What Are The Commonly Used Roofing Materials?

What Are The Commonly Used Roofing Materials?

A roof can be made with a range of synthetic and natural materials. From straw to rubber, nearly anything can make a roof. What we need to know is how durable and functional roofs made of different materials are, what type of problems they each encounter and how long they typically last. Some of these are discussed below.

Concrete is a very resilient material and makes excellent roofs. It is however heavy and also cracks under temperature stresses. It is best for concrete structures as wooden houses may be too weak to withstand its weight. Using concrete shingles, slabs and pouring concrete in steel frames are ways to make a concrete roof.

Asphalt is used for roll roofing as well as for making asphalt shingles that can be used to make a roof. Asphalt is probably the cheapest and most common roofing material in America. Asphalt roofs are really easy to install. Temperature induced tearing is more common in roll roofing and shingles are therefore more durable.

Slate roofing is done using slate tiles. Slate is essentially stone and is extremely durable and can be modified to look like wooden tiles as well. Because slate is also heavy material, the structure should be stable enough to support the slate roof.

Wood shakes are high maintenance and not the most resilient roof materials. This is because they are neither fire nor wind resistant. They will let fungus grow on them and rot in time as well. They need fire retardants to be applied on them. The benefits of wooden roofs are that they make up in looks what they lack in durability and they are environmental friendly and lightweight.

Although metal roofing is not popular for houses, it is a great choice in terms of appearance as well as strength. Not many contractors deal with metal roofing and you may have to search to find those who do. When it gets oxidized, copper looks brilliant, but galvanized steel is the metal of choice for residential roofing. Soldering and screws are used to hold together both corrugated and flat sheet metals used for metal roofing.

Bitumen, EPDM rubber, PVC and CSPE plastics are some of the materials used for membrane roofing, which is a popular flat roofing method. Most roofs made of one of these instead of asphalt have better features than asphalt roofs. To install these roofs, heat welding, an adhesive or tape is used.

Straw and seagrass are used till date to make roofs. Roofs made of other natural materials like ceramic, clay and terracotta are also very popular and have the benefit of being fireproof and ‘green’. In addition to this, they have great aesthetic appeal. Many roofs also have solar panels, which is indeed a very useful addition.


Five Common Roofing Problems You Should Know

Five Common Roofing Problems You Should Know

Your roof will require proper care and maintenance to ensure that it functions correctly, and that it looks good all year round. If you suspect that you have a problem with your roof then you will need to get it fixed as soon as possible. Failure to do so could result in serious damage, both to your roof and to the interior of your home. This article takes a look at five of the most common roofing problems, and it also explains how you can locate and choose a roofing repair specialist in your area.

Damaged Flashing

The flashing refers to the thin metal which is designed to keep water from seeping through the shingles. It is typically installed around the roof’s edges, and around skylights prior to the installation of the shingles. Flashing can become damaged due to harsh weather conditions or because of poor installation. Damaged flashing will result in leaks which can cause serious problems in your home.


Rotting can occur when moisture gets into the core of the shingle. Rotting roofs should be seen to immediately to prevent the rot from spreading and causing more damage.

Buckling Shingles

When a roof is not properly ventilated the shingles can become buckled. Buckled shingles can lead to leaks, therefore it is essential that a specialist roof repairer comes and fixes the problem quickly. In some instances you may require a new section of roof in order to repair the problem.


The shingles can also curl due to poor ventilation, high nails, or the wrong type or number of fasteners. Curled shingles look unattractive, and they can also lead to leaks.

Ceiling Spots

Ceiling spots are marks which appear on the ceiling inside of your home. They can indicate that there is moisture seeping through the roof of your home. Ceiling spots mean that you need to hire a professional to take a look at your roofing immediately. If you don’t the water will continue to seep through and cause additional damage to your ceiling. Not only does it look unsightly, but it can also pose a safety risk to you and your family as the ceiling can collapse if the problem is not addressed.

How to Find and Choose a roofing Repair Specialist

The best way to locate a roofing repair specialist that serves your area is to search for their website online. All good roofing repair specialists will have a website which will list more detailed information on the services that they offer as well as their contact details. Before you hire a roofing specialist you should ask them some questions to ensure that they are the right person for the job. These questions can include things like:

* How long have they been working as a roof repair specialist for?
* What qualifications do they hold?
* Is the work guranteed?
* Is there a waiting list?
* Do they offer free quotes?
* How much do they charge?
* What payment methods are accepted?

Always choose an established and trusted company or individual to ensure that you will be receiving a high quality service.


The Most Popular Metal Roofing Products

The Most Popular Metal Roofing Products

There is a wide variety of metal roofing products on the market today. Most of these materials are more expensive than standard fiberglass and asphalt shingles, but their durability and extended life spans make them viable options for both residential and Commercial Roofing applications.

Below is a list of the most popular metal roofing products:

Corrugated Galvanized Iron, or CGI, is the roofing material which is often seen on sheds and barns. This steel roofing, which is cheap and lightweight, is still used in developing countries for residential purposes; however, the problem with CGI is that rusting is inevitable with time even though it has been galvanized.
Galvalume is a combination of steel, zinc, and aluminum, and is one of the best roofing materials due to its corrosion resistance and long life. It is strong and light weight but will not crack or peel when subjected to the elements. Galvalume is factory painted which adds an additional layer of protection and provides the customer with a wide selection of colors to choose from.
Stone Coated Steel consists of structural grade steel panels coated with a corrosion resistant aluminum-zinc alloy, topped with a layer of granite stone chips. The stone chips are ceramic coated to increase ultraviolet resistance and provide color to the panels. This type of roofing is very durable and is normally guaranteed to withstand damage from hailstones up to 2.5″ in diameter.
Aluminum is the metal roof of choice for those who put a premium on quality. Aluminum is a lightweight yet very durable metal which can be formed into intricate designs. It is a popular roofing material on coastal area due to its resistance to rust and corrosion. One additional advantage of aluminum is that it is environmentally friendly-it is totally recyclable.
Stainless Steel is an alloy that contains at least 10.5% chromium which gives the material an inherent ability to protect itself from corrosion. Chromium forms an invisible film of protection on the steel and, if the panel is damaged, the chromium reacts with oxygen present in the air to regenerate the protective film. Initially, the cost of stainless steel is typically higher than other metal roofing products but its durability and strength could prove more cost effective in the long run. The Chrysler Building in New York City, built between 1929-1932, is an example of the longevity found in a stainless steel roof.
Copper roofing is expensive but has several desirable properties. It is popular in areas prone to forest fires due to the fact that it is highly resistant to fire–it can even extinguish small embers. It is also favored in areas of heavy snow falls since the snow will easily slide off a roof with a sufficient slope making the possibility of a roof collapse almost nonexistent. Copper is susceptible to oxidization, but it does not affect the quality of the metal. Over time oxidation will change the color of the copper into a jade-like green patina which is very resistant to corrosion.

For someone wanting an attractive and long-lasting roof, metal may be the best choice.


Finding a Reliable Commercial Roofing Service

Finding a Reliable Commercial Roofing Service

The storm’s come and gone. Now, what’s left behind by the storm is a broken roof over your place of business. Your stocks have also faced some damages with no roof over them. You have faced a great loss. But no fret, you can always get your roof fixed, and get new stocks in. Yet, is it that simple to minimize your losses? While you may not need the best roofing services, you will want an honest one who would not rip you off. Read on to learn how to find an honest Commercial Roofing service.

First thing you should do is to enquire from other local places of business on whose Commercial Roofing services they have tried and recommends. Do not think that just because a service may appear professional at first means that their work would also be professional. Recommendations are always a good place to start.

When you are surveying for the service, listen out to what their salesperson has to say. If their pitch seems absurdly too good to be true, there may be lots of hidden painful truths lingering behind it. It could be a low estimate, with lots of hidden cost, or a buy now to enjoy great offers kind of thing, but end up you have to pay additional costs to enjoy better offers. Just be careful with such salesperson’s pitch.

Different types of roofing jobs will cost differently, depending on the complexity and the materials. Try to get quotes from different services and compare them before settling for one. For the same thing, they should cost average out the same, so beware of an extremely low or high-priced service.

Lastly, ask the right questions. Some questions you should pose are whether they are a registered trade member, what kind of insurance they have and cover, and if they charge for estimates. Estimates should generally be free.

Some Benefits of Metal Roofing

Some Benefits of Metal Roofing

When considering what type of roof to put on your new home or to replace your roofing with, metal roofing is certainly worth considering for its many benefits and qualities; especially if you live in a climate which is subject to heavy snowfall.

A variety of metal roofing materials are available, from the more familiar standing-seam sheet metal roof to newer, specialized metal roof shingle products that look more like tiles.

Read on to learn some of the benefits of metal roofing materials over other types of roofing products.

Metal roofing Service Life

When correctly installed, a metal roof can last as long as the house itself and will seal out water, withstand high winds, and shed snow with ease. A metal roof is quite fire resistant and prevents problems such as mildew, insects, and rot from occurring. Warranty terms vary for metal roofing materials, but most reputable manufacturers warranty their products from twenty to as much as fifty years!

Easy, Speedy Metal roofing Installation

Typically, metal roofing materials are delivered in multi-shingle sheets or sections, which make installation very quick for an experienced roofing contractor. When your old roofing has been stripped, you want to get the new roof installed as quickly as possible before inclement weather potentially damages your home.

Metal roofing Heat Conduction Qualities

A metal roof is very effective in reflecting the radiant heat of the sun during warm weather, helping keep your home cool. Despite the fact that metal roofing will have a low R-value, most metal roofing systems incorporate dead air space between the deck of the roof and the roofing material to increase insulation and energy efficiency.

Metal roofing is Light Weight

When compared to most tile roofing at 750 pounds per square (100 square feet) or concrete tile roofing at 900 pounds per square, metal roofing materials are quite lightweight; the average metal roofing materials weigh between 50 and 150 pounds per square.

In some cases, a metal shingle roof can be installed over existing roofing without the expense of tear off or the addition of structural support changes to the roof, since in most cases it will be lighter than the previous roofing material!

Fire Resistant Metal roofing Materials

Since metal is noncombustible, a metal roof has a Class A fire rating, meaning it is considered the most fire resistant type of roof available.

Installing your metal roofing over an existing wood roof does decrease its fire rating since the old materials below your new metal roof will be combustible. For this reason, it is generally worth the additional cost of having the old roof torn out before installing metal roofing.

Metal roofing Doesn’t Require a Steep Pitch

Since a metal roof is quite effective in shedding water and snow, it can be installed on a less steeply pitched roof without danger of leaking. On a new home designed with metal roofing in mind, the pitch will generally be three in twelve, meaning the roof rises three inches per horizontal foot.

With all these advantages and benefits, it’s easy to see why so many homeowners are choosing metal roofing systems these days.


Things You Need to Consider When Choosing a New Roof

Things You Need to Consider When Choosing a New Roof

There are so many different roofing options from slate to rubber roofing and more, so ensure you ask yourself the following questions and identify the answers to help you make the best decision to meet your unique needs and budget.

The first factor to take into consideration is the lifespan of the roof. Some roofing materials will provide you with years of use and enjoyment, most should last a number of years and some can last up to fifty years, if not more. Rubber roofing tends to last around fifty years, while tile and slate can last twenty years, sometimes more, depending on the climate and weather conditions.

You need to look at how the roof will handle the elements. This will be determined by where you live, if you live in a cooler and wet climate, then you want to find a product that can handle high volumes of water and ice, a material which is waterproof to protect the interior of your home and provide you and your family with complete peace of mind at all times.

The slope of the roof is also important, bearing in mind that some roofing materials are ideal for pitched roofs, some are better suited for flat roofs and some can be used on all types of roofs. Speak to your roofing specialist to get ideas on what materials are going to be best suited to meet your roofing needs. This will help you identify the materials you can use, you can then review and compare them to identify the one you feel is the perfect match for you moving forward.

Weight plays a very important role and you want to ensure when choosing a new roof that you choose a roof which can easily be supported. This is probably one of the most important factors and you need to also take into account what happens if it snows, bearing in mind that the walls will have to withstand the weight of the roof and snow. Ensure you choose a material which is lightweight enough to provide you with a roofing solution that will not collapse or cave in when you least expect it.

Eco friendly has become a word that many people use when it comes to building or repairing their home and if you are looking for an eco friendly roofing solution, then rubber may be the way to go. Rubber roofing is made from recycled materials which provides you with an environmentally friendly and eco friendly solution. The rubber reflects the heat, which helps keep the property cool during the summer months.

In addition to this, your final consideration when choosing roofing for your home is the price. You don’t want to break the bank, but at the same time, the roofing option you choose will add value to your home for the future. Don’t focus on price along, set yourself a budget and then see what roofing options fall into that budget.


Metal Roof Restoriation

Metal Roof Restoriation

An overview of how a Metal Roof should be Sealed with An Elastomeric Roof Coating. Also discussed are the advantages of a elastomeric roof coating product.

A metal roof can be a challenging roof surface to seal from the elements. One of the major factors is the constant expanding and contracting of the roof surface itself. A metal roof can expand and contract as much as 2 inches every 100 feet which can be devastating to fasteners and seams, which 90% of all roof leaks occur at these points.

If you are experiencing problems with a metal roof then the two options are to either replace the roof which can be extremely expensive and time consuming or restore it with a elastomeric roof coating, which can be very cost effective as compared to replacing the roof.

A high quality elastomeric roof can add many years of life to your existing roof, they come in many different forms but the high quality ones are generally more expensive but should be the only choice. Lower cost coatings dont stretch as well and seldom have the proper UV protection built into them.

Another key feature in Elastomeric roof coatings are the energy savings you will benefit from them. Immediatly after coating the metal roof surface its temperature can drop as much as 40 degrees or more in a very short period of time. This reduction in heat transfer from your roof will make your building much cooler and will save your money in your energy bills.

The roof coating however does not simply just work alone, there are steps necessary to ensure that your roof is properly sealed from the elements and it’s better to be done by a professional roof coating contractor.

The first thing that must be done is to ensure a clean roof surface, this should be done with a high power pressure washer to remove hard to get roof scum. Next you need to go around the roof and spray all rusty areas with an inhibitor to stop further corrosion of the metal. You should then go around and reinforce any where there is a roof penetration with elastomeric roof cement, by penetrations I mean pipes, air ducts, fan units and any other areas where there is something entering through the roof surface. You then also need to go reinforce or replace rexisting roof flashings that may be running around the roof.

After the roof has dryed the next step is to seal fasteners individually with a rivet guard type material and all missing fasteners should be replaced as well. After this step you must individually seal every seam with a seam guard, this is usually a roll out tape, a really thick elastomeric cement or a combination of both of pending on the product you are using.

Now finally you can coat your roof with the final roof coating to finish the job. You will need a roof coatings sprayer which you can pick up from a paint supplier just be sure that you change the sprayer head with the proper size for your roof coating. You may need a primer coat depending on which product you are using and you should put down two coats of finish roof coating material as well. Be sure that the roof surface is dry and that now rain is forcasted for the day you decide to finish the roof. Elastomeric coating will not stick to a wet roof surface so be sure that it is good and dry. Temperature is also an important factor, it should be no less then 55 degrees to put down the roof coatings to ensure that it cures properly.

That is pretty much how you would go about sealing your metal roof. But it is much better to hire a qualified roof coatings contractor to do the work.


Some Tips on Roof Installation, Repair and Choosing a Roofing Contractor

Some Tips on Roof Installation, Repair and Choosing a Roofing Contractor

Our home is one of the must important assets that we own and often it requires maintenance and remodeling of one kind or another. We all dream and aspire to have a place where we can retreat from the stresses of the out side world and connect with ourselves and with our family. This necessity it is not a cheap one but rather something that takes time and money as well as a good home remodeling & repair company to achieve. A home is as personal and as precious as a beautiful piece of jewelry and just like an expensive diamond is handled by a professional jeweler so too a home should be given to a good home building contractor to remodel or maintain.

Roof maintenance, unlike other home repairs and remodeling, is not something you can just put off for next year. When one finds a roof leak it needs to be fixed right away or at least before the next winter shows up, otherwise the water damage caused by the leaking roof can be substantial and can lead to unnecessary expenses in the long run. The urgency of roof maintenance is important also for making your home more energy efficient and for reducing high energy bills. As a matter of fact professional craftsmanship in roof repairs and installation is the first step in improving energy conservation and efficiency for your entire home and you’ll be amazed at the positive effect this will have on your utility bills.

Most roof types and materials are very durable and can last for many years, but because at least 40 % of your home’s front elevation is the roof, it is constantly exposed to changing weather conditions that can cause damage and can make the roof look dirty and neglected. Thus, whether it’s a tile roof, shingle roof, or even steel roofing, periodic roofing services would be necessary and when it does it needs be taken care of by a professional roof contractor.

In addition to natural causes, sloppy craftsmanship is another common reason for leaking roof and other roof related issues. If the roof installation was not done properly, by winter time you will surely know about it. For example – If the parameter edge is re-roofed without a starter shingle or if the starter shingle is improperly installed, you definitely have a problem there. Exposed fasteners and nails that are not sealed will eventually cause a roof leak. Improper installation of counter flashing or missing counter flashing under the step flashing, no underlayment, debris in the gutters, rough cut shingles are also examples of bad roofing that one should watch for.

Some general rules to follow when considering the type and color of your new roofing is also in place. Today what we predominantly see in terms of roofing materials are tile roof & steel roof or metal roofing systems, as well as the fiberglass shingle roofing system. In the shingle roof system you have the standard fiberglass roofing or you have what is called dimensional roofing which is becoming popular and is considered as high-end roofing. In selecting your roofing it is really going to depend on what is predominant in you neighborhood or if you are looking for a unique look you would want the roofing to match in with the bricking or sidings of your house. If you have lighter shad bricking or sidings you don’t want go for a really high contrast where you have a really dark roof but rather you should go with a lighter shad approximate to your sidings. Basically the roof needs to blend with the color of your brick, sidings and the gutter system. For instance if the sidings are of a lighter shade tone you need more or less a lighter shade color for your roof, like light grey or a light brown.

In a last note – remember that cost does not determine quality, and not all of kinds of roofing will meet the needs of your specific home. But by carefully selecting the right roofing material and making sure it’s installed properly by a licensed roofing contractor and by performing maintenance occasionally, you can have a roof that functions properly for 20 to 30 years or even longer.


Is It Possible To Lay New Roof Shingles Over Old?

Is It Possible To Lay New Roof Shingles Over Old?

The answer is yes, you can lay new roof shingles over old ones. Now that we’ve taken care of the primary question at hand, we’ll consider a couple of reasons why you might want to do this. Then we’ll look a lot more reasons why you might not want to do this. But before we get started, one thing must be clear: adding new roofing over old (sometimes called a re-roof) is possible only with asphalt shingles (also called composition shingles). You can’t do it with wood or slate, for example, and you should never mix materials, such as laying asphalt shingles over cedar shakes. Also, the old roofing has to be in pretty good condition. Otherwise you’re just putting lipstick on a pig (but let’s leave politics out of this).

Why Add New Roof Shingles Over Old?

Contrary to what might seem like an obvious benefit, having multiple layers of shingles does not necessarily make a roof more, for lack of a better word, waterproof, and it often creates its own problems. So why would you lay new roof shingles over old? Convenience and cost. If you keep the old shingles on, you skip the messy, laborious removal step — called the tearoff — and you’ll save some money on the roof job.

However, both of these benefits have caveats. It’s clearly easier and cheaper to leave the old shingles in place, but there’s some special prep work involved with a re-roof (removing vents, ridge caps and misshapen shingles, among other things) and you still have to replace or add new flashing, which sometimes can be tricky over old roofing. Eliminating the tearoff can easily save $1,000 or more on a new roof, but you’re really just delaying the cost: when it’s time to replace the roof again and you have no choice but to start anew (two layers is the maximum allowed in most areas), you’ll have to pay extra for the two-layer tearoff and disposal.

Why Not Add New Roof Shingles Over Old?

As suggested above, the potential cons of re-roofing tend to outweigh the potential pros, but it all depends on your situation. The following list includes some universal reasons not to reroof as well as some considerations or things to check out if you’re seriously considering adding new roof shingles over old ones.

1. Shingles are designed for flat surfaces. They don’t do a good job of bridging over gaps, dips or humps, including the stepped texture created by overlapping shingles. Re-roofers have tricks to lay new roof shingles over old so that the same step-ups between courses are maintained, but if any old shingles are cupped, curled, or otherwise misshapen, those defects will “telegraph” through to the new layer. Many roofers recommend using laminated, or dimensional, shingles for re-roofs because they’re thicker than standard shingles and often have a staggered edge profile (for looks) that helps hide any dips or high spots in the old roofing.

2. Shingles add weight. Good-quality composite shingles can weigh 350 to 450 pounds per “square” (100 square feet of roofing, installed). Chances are, your roof structure was designed for a dead load of one layer of shingles, plus extra for snow and a safety margin. Installing new roof shingles over old effectively doubles the weight of the roofing, so you have to make sure your roof structure can handle the extra load. That’s also why building codes commonly limit re-roofing to no more than two layers. On some houses, the extra weight of multiple layer causes the roof sheathing (decking) to sag between the rafters or trusses.

3. No visual inspection of roof sheathing. Without a tearoff, roofers can’t see what the decking looks like. A good roofer will perform a careful “walking” inspection for spongy areas and other problems, and they can make localized repairs before re-roofing. A not-so-good roofer might be less conscientious.

4. Can’t replace underlayment. The building paper (tar paper) that’s laid between the roof sheathing and the shingles is there for a very good reason — because water has a way of getting under shingles, no matter how many layers of roofing you have. If the underlayment is old and deteriorated, it won’t protect your roof deck from water that gets past the shingles. In snowy climates, most new roofs these days get an ice-and-water shield (a rubbery moisture membrane) applied to the sheathing along the eave to protect against ice dams. Adding this membrane isn’t an option with a re-roof, and the extra layer of shingles offers little protection against ice dams.

5. Re-roofing may affect the warranty on the new shingles. Pretty self-explanatory. Be sure to check with the shingle manufacturer regarding all warranty issues and installation requirements before re-roofing.

6. Local codes might not allow re-roofing. Two layers is the maximum in most areas, but some building codes allow only one. For example, towns in climates with heavy hailstorm activity or significant ice dam problems may not allow multiple roofing layers.

7. A re-roof might not look good on an inspection report. Adding new roof shingles over old ones is tempting to a lot of people planning to sell their house in the near future: why pay for a tearoff if you can get away without it? Of course, it’ll be the new owners who are stuck with the extra expense of a two-layer tearoff down the road, along with any problems arising from an improper re-roof job. Because of this, home inspectors often report double-layer roofs when they find them, and they may warn the buyers of potential problems associated with re-roofs. If you’re planning to sell your house after installing a new roof, it’s a good idea to discuss your options with local real estate pros and/or home inspectors.
