A Certified Roofing Contractor-Your best Choice – This informational article gives insight into the various choices in roofing and their special needs. A certified roofing contractor knows how to meet those requirements; this article offers valuable information to help select the best contractor for your project.

The life expectancy of your roof depends on several factors

Type of roofing, quality of material, and exposure to harsh weather elements among the top. With regular maintenance and normal weathering factors, a roof can last anywhere from 10 – 100 years.

Common roofing material such as built up roofing usually lasts 12 – 20 years, metal roofing 15 – 40 years, wood shake or shingles 10 – 40 years, asphalt shingles 15 – 20 years, and specialty material like slate up to 100 years under good conditions.

Leaks start as small cracks in roofing material that may not be visible; water may collect in an adjacent area. To detect such damage, a close inspection of the roof may be necessary.

A certified roofing contractor can be called to avoid further damage to the roof, or personal injury to the homeowner caused by trying to inspect it his or her self. A roof inspection should be performed annually; constant weathering by sun, heat, rain, snow, hail, wind, and cold can cause roofing material to break down. A certified roofing contractor will know what to look for.

A roof and soffit system should be properly vented to prevent over-heating and moisture retention, two factors that can cause a roof to break down prematurely.

Selecting a Qualified Roofing Contractor

A certified, experienced contractor offers various services. From completely tearing off an old roof and replacing it with a new one, to inspecting and “certifying” an existing roof. The latter is a process in which the roof is inspected and “guaranteed” to function properly for a certain period of time; usually 2 years. The contractor takes responsibility for any necessary roofing repair during that period.

A certified contractor is knowledgeable of roof system types, materials, and installation procedures best suited to each project, and will ensure there is adequate venting.

Ask potential roofing contractors questions such as whether or not they are licensed and bonded. What liability insurance coverage they carry, and whether it is up to date. Ask which roofing product manufacturers they are licensed and approved by, for installation of products and warranty purposes. Also, ask if they are a member of any regional or national trade organizations.

Several resources are available to find a certified roofing contractor; referrals, local government licensing agencies, and websites that offer contractors for hire, or a list of contractors who are licensed and bonded.

Why a slate roof ?

why a slate roof - roofer made a roof with slates

Why a slate roof ?  Primarily used on steeply pitched roofs, slate is used in Brittany because of its proximity to mining sources (Brittany, Anjou), but also because it is an integral part of the landscape of western homes, as are clay tiles in the south of France.

What are the style and color options for slate roofs?

There are many styles of slate roofing, ranging from textured and graduated installations to mixed colors and patterns. Two of the most common styles are the standard pattern style and the random width style. Slate varies not only in style, but also in texture, which can range from very smooth and uniform to very rough and rustic. Slate colors range from muted colors to bright colors. Grays and blacks are the most common colors, but greens, purples and reds are also available.

Why a slate roof ? How long does a slate roof last?

Slate is essentially a rock, a homogeneous metamorphic rock that is derived from an original schist-like sedimentary rock composed of clay or volcanic ash through low-intensity regional metamorphism. Therefore, this roofing material is millions of years old. Slate is incredibly durable and can last several hundred years, often with little or no maintenance. It is safe to say that your roof will last you at least 75 to 100 years or more. However, it is important that you do not put anything on your roof, such as sealant or paint, as this can cause the roof to age prematurely.

What are the advantages of slate over shingles?

Slate is what we like to call a “forever roof” because homeowners will only need to install one in their lifetime, whereas a shingle roof may need to be replaced two or three times. Another benefit of slate roofing is its ability to increase the resale value of your home due to its natural beauty and durability. Slate is known as an elegant roofing material that will enhance the architectural style of your home and maintain the same appearance over the years. Other benefits of slate include its natural ability to resist fire and mold, as well as its low water absorption, which makes it highly resistant to frost damage and frost breakage.

Why a slate roof ? What should you do to prepare your roof for slate?

Slate is an extremely heavy product and can add an additional 200 kg to your rooftop. If your home is not designed to accept slate, you will need to have your rooftop inspected by a structural engineer. The engineer will ensure that your rooftop is ready to support the weight of the slate roofing.

Why a slate roof ? What is the price difference between slate roofing and shingle roofing?

Slate is an expensive product and you can expect it to be two to three times more expensive than a standard architectural shingle roof. The price can vary from 35 to 55 euros per m2. The price of a canopy also varies depending on the size of the house and the pitch of the roof.

Why a slate roof ? Can a slate roof be repaired?

You can repair your slate rooftop at any time. It is important to have a licensed roofer examine your covering to find any damaged parts. Repair is as simple as sliding off the damaged slate and replacing it with a new piece. Having your roof professionally inspected once a year will also help keep your slate in the best condition possible.

Roof Preparation before Installing Roof Shingles

Roof Preparation Installing Shingles roofer VancouverRoof Preparation before Installing Roof Shingles : installing roof shingles can be an arduous task and should not be attempted if you don’t know what you are doing. It is vital to ensure that you complete adequate roof preparation before installing roof shingles otherwise you are risking the integrity of your new roof. A poorly prepared roof can quickly lead to holes and cracks that will in turn lead to a leaking roof, notices Vin Faugeres . Obviously, the first part of your roof preparation before installing roof shingles is to rip off the hold or damaged shingles that you are replacing. While it is possible to leave these on if they are showing any signs of damage or wear you should replace them whenever possible.

Secure the roof boards

If you are using the same roof boards without replacing them you really should check each and everyone to make sure none of them need replacing. Make sure they are all securely fastened down to prevent any damage to the lining or to the shingles. You also need to make sure there is no debris lying around because this too can cause damage to your new roof. Make sure no nails or other objects are protruding out of the roof.

Installing the drip edge.

Install the drip edge around the eave ends of the roof. Be sure to use galvanized nails so that they don’t rust in the rain. When adding the drip edge to the top of the roof install in the same way but this must drape over the rest of the drip edge to be effective. If you need to make any joints because the length of the drip edge is not long enough to fit down the whole length of the eave then simply overlap the two pieces and bend the aluminum into place.

Ice and water shield.

You should consider putting down a layer of ice and water shield. Some states require that you use this and have set distances that the shield must be from the wall. It is very good stuff and incredibly adhesive so place it down where you want it to go before removing the backing paper. Once it’s stuck there is no way of removing it. Ice and water shield will cost you a fair amount at around $50 per square foot but the job it does is invaluable and a vital step when you are finishing your roof preparation before installing roof shingles. Cover any large knot holes with aluminum flashing or similar material and hammer these down (you may want to use a hammer tacker or nail gun to make this step a little quicker and easier).

Adding the layer of felt.

Overlap you are felt by a few inches and completely cover one side of the roof. To install a roof vent at this point you should cut a small part of the roof on either side of the peak virtually the whole length of the roof. Now cover the remaining side of the roof with felt and also cover over the roof vent hole you have created. This will be cut later. You have now finished the roof preparation before installing roof shingles and are ready to shingle your roof.

Flat Roofs

 flat roof lexington ky

Flat roofs are a great way to keep a building safe from water. Knowing exactly what to do with a flat roof will ensure you have a working roof system that will last a long time.

Though they may look good and are very common, flat roofs do require routine maintenance and detailed repair in order to effectively prevent water infiltration. If this is done correctly, you’ll be happy with your flat roof for a very long time.

Flat roofs aren’t as glamorous and/or popular as its newer counterparts, such as slate, tile, or copper roofs.

However, they are just as important and require even more attention. In order to avoid throwing away money on short-term repairs, you should know exactly how flat roof systems are designed, the various types of flat roofs that are available, and the importance of routine inspection and maintenance.

A flat roof system works by providing a waterproof membrane over a building. It consists of one or more layers of hydrophobic materials that is placed over a structural deck with a vapor barrier that is typically placed between the deck and the roof membrane.

Flashing, or thin strips of material such as copper, intersect with the membrane and the other building components to prevent water infiltration. The water is then directed to drains, downspouts, and gutters by the roof’s slight pitch.

There are four most common types of flat roof systems.

Listed in order of increasing durability and cost, they are: roll asphalt, single-ply membrane, multiple-ply or built-up, and flat-seamed metal. They can range anywhere from as low as $2 per square foot for roll asphalt or single-ply roofing that is applied over an existing roof, to $20 per square foot or more for new metal roofs.

Used since the 1890s, asphalt roll roofing generally consists of one layer of asphalt-saturated organic or fiberglass base felts that are applied over roof felt with nails and cold asphalt cement and usually covered with a granular mineral surface. The seams are typically covered over with a roofing compound, explains Code postal Nantes . It can last about 10 years.

Single-ply membrane roofing is the newest type of roofing material.

It is often used to replace multiple-ply roofs. 10 to 12-year warranties are typical, but proper installation is crucial and maintenance is still required.

Multiple-ply or built-up roofing, also known as BUR, is made of overlapping rolls of saturated or coated felts or mats that are interspersed with layers of bitumen and surfaced with a granular roofing sheet, ballast, or tile pavers that are used to protect the underlying materials from the weather. BURs are designed to last 10 to 30 years, which depends on the materials used.

Ballast, or aggregate, of crushed stone or water-worn gravel, is embedded in a coating of asphalt or coal tar. Since the ballast or tile pavers cover the membrane, it makes inspecting and maintaining the seams of the roof difficult.

Lastly, flat-seamed roofs have been used since the 19 th century.

Made from small pieces of sheet metal soldered flush at the joints, it can last many decades depending on the quality of the material, maintenance, and exposure to the elements.

Galvanized metal does require regular painting in order to avoid corrosion and split seams need to be resoldered. Other metal surfaces, such as copper, can become pitted and pin holed from acid raid and usually requires replacing. Today copper, lead-coated copper, and terne-coated stainless steel are favored as long-lasting flat roofs, explains Roofer Lexington KY

Guide To Hiring A Roofer

Guide To Hiring A santa rosa Roofer

Guide To Hiring A Roofer : the average life of a roof is approximately fifteen years. If the roof is under fifteen years old yet you are having problems, it will likely be able to get repaired as opposed to having to install a completely new roof. However, if your roof exceeds this age it may be necessary to install a new roof. To accomplish either repairs or new installs, a roofing contractor should be employed. A roofer will be able to properly install or repair roofing materials to ensure a quality finished product.

Before hiring a roofer it is always wise to get recommendations from friends or family.

Whether or not you have recommendations, get several quotes before determining the roofer to hire. A quote should be detailed and include the work to be done, cost, and time-frame for completion. Be sure clean up is included in the quoted price. If you want to save some money, offer to do the cleanup yourself.

Ask the roofer how long they have been in business. Roofers with many years of experience are preferable, adds modifier stl. Also, make sure they have a physical address. Many roofing scams are conducted by people working out of a truck with no valid business license or permanent address. Ask for references and check them. Roofers should be properly insured. Ask for proof of insurance to be sure you are protected from any damage to your home.

Roofing repairs and new roofs may require specific building permits.

Make sure the company you work with is familiar with local building codes and that they obtain proper licenses or permits. Most locations also require inspections during certain phases of construction and a final inspection when the work is complete. Check your local building codes to ensure the roofer is complying with all regulations. You may be liable if this does not occur.

Before starting the project get a contract. This should include all the details of the project, time frame for completion, and price. It should clearly outline payment policies and warranties. Read the warranty carefully to make sure you are adequately protected. Also, be sure the contract states they are responsible for clean up. Roofing materials can be very messy and you do not want to have to clean up and dispose of waste yourself. But keep in mind you can save yourself some money if you choose to tackle the cleanup process yourself.

Never be rushed into hiring a roofer.

Take the time to interview potential roofers and check experience and references. Roofing repairs can be expensive and a new roof is a major investment. Protect your home by doing some research. Hire the roofer who has the best combination of experience and price and with whom you feel most comfortable.

The Truth About Roofs

The Truth About westminster roofers

The Truth About Roofs : if you’ve got roofs, then it’s a matter of time. Read Bruce’s pragmatic advice for finding the source of roof leaks quickly and efficiently

You can’t have too many roofs in your inventory without dealing with leaks. If you rehab, you EXPECT to find ceiling stains, the tell tale sign of a leaky roof, in almost every project. I find projects without signs of past or present leaks the exception to the norm!

Sometimes shingles are just going to need replaced.

There is no getting around it, says fonction matlab . Curled shingles and numerous leaks are a pretty good indication that it would be cheaper to replace the roof rather than repair it. Just factor that into the repairs and accept it. It’s one thing you won’t have to worry about if you are keeping the property, and it ups the value whether you keep it or sell it on the retail market after the rehab.

If the shingles still have some life on them, but there is some leakage to repair, finding the real source of the problem can take multiple tries. It can get pretty aggravating as you sometimes try and fail to fix a leaky roof. Naturally, you want to try to fix this without calling out an expensive professional roofer. Sometimes you can, sometimes you can’t. Here are some tips for diagnosing roof leaks.

– I find that in the course of a rehab, it’s always “good” to have an extended period of heavy rains.

That way, any and all leaks become evident. If you have a property that is not occupied, or that is not being actively rehabbed after a period of extended rains, go visit and check for signs of leaks. If you can stop by while it’s still raining, that’s the number one, best time to investigate leaks from inside the attic.

– Get a mini flashlight that goes into a small belt holster and make that part of your normal clothing.

You will use it all the time…for more than looking in attics! It’s great for plumbing, under cabinets, etc. Make it part of the “uniform.”

– The garden hose – a rehabber’s friend.

In a recent project of mine, the roof was relatively new yet I had a ceiling stain in the kitchen. We’d thought it was all taken care of in two tries, so we patched the ceiling, applied stain block, and textured over the spot. Then came the rains, and the circular and symmetrical spot was back! I’d had just about enough so I climbed onto the roof, garden hose in hand, and stationed my handyman in the attic. In less than a minute of hosing down the roof, we found the very tiny hole that was the culprit. A dab of tar below and above the shingle and viola! Problem solved. The tiny hole was causing water to drip directly onto the ceiling drywall, hence the circular stain.

– Watch for stain patterns.

The pattern can offer you hints. When you come across a circular ceiling stain, there’s a good chance the leak is dripping directly onto the ceiling drywall from above. Put a nail in the center of the stain and get into the attic and look directly above the nail and you might just find the problem. If you do this in bright daylight, a spec of light might be visible, which would make the repair a little easier. Even if you find a hole, I still recommend the garden hose trick to see if there are other problems to fix.

If the stain is small and circular, it usually means the amount of water is small…lucky you. If the stain region is larger, it may still be an easy fix especially if it is a single hole. If there is enough rain making onto the ceiling drywall, it will pool and soak in. This will make it look like a massive leak when it might be a one-shingle repair (plus some new ceiling drywall). The garden hose trick will quickly tell you if the problem is a single hole, or your roof is like Swiss cheese.

Stains that appear along a line may indicate that water is draining along a rafter or truss. Inspect that rafter starting from the top looking for signs of water. The source may be a single hole that is sending water down the rafter making multiple stains show up in a line.

– Isolating the leak. Be aware of the ridgeline.

When you are inspecting a property, be aware of the direction the roof ridgeline runs as you inspect the interior. If you come across a ceiling stain toward the middle of the house near where the ridgeline is above you, the source of the water is easier to isolate. Water doesn’t flow up! So, the suspect area extends from roughly the stain area, up to the ridgeline. In many cases, that’s a lot less roof to investigate.

On the other hand when stains are out near the roof edges, they are the trickiest to diagnose. Why? The source of the water could be from higher in the roof than where the stain is. The water could be getting under a shingle near the peak, draining down between the shingles and ply, and finally leaking at the point you are seeing the stain. It’s just hard to tell upon initial inspection. Get into the roof and check out the rafters around that area for signs of water stains? If you’re lucky you’ll see light and a hole. If you’re not that lucky, it’s time to get on the roof and see what you can find. If you don’t find anything obvious, it’s time to call a roofer…that is, unless you decide to replace the whole roof.

– Valleys are often the culprit when it comes to leaky roofs.

I especially find this in property that has been neglected or vacant for long periods of time. Very often the problem is caused because leaves have accumulated in the valley. These leaves hold moisture which rots the shingles and underlying ply over time. Depending on the extent of the rot, the repair can range from replacing ply and shingles to cleaning off the leaves and letting it dry. Be aware of your roof valleys and keep them clear!

With roof leaks, there are no shortcuts. It’s easier and cheaper, in the long run, to aggressively diagnose the leak problem and seek hidden leaks that just haven’t soaked through the ceiling drywall yet. Don’t assume that once you find one hole in the roof or a cracked shingle that the problem is fixed. Get that hose out and confirm it! There is something about climbing in an attic and on a roof that isn’t fun to re-do.
