The roof of your home is one of its most important features, but it is also one of the most neglected. An aging roof can cause serious problems to your house and some of them may not be visible until it is too late. For example, water could damage the decking or frame. To reduce your risk, it is important to have the roof inspected on a regular basis, especially after heavy rain or strong winds. Quite often, a Roofer in Johnston will offer discounts on roof inspections or perform this service as part of the repair.
The typical household roof is a pitched affair that uses a man-made decking over a structural framework. This decking is usually OSB (Oriented Strand Board) or plywood. Over the decking is a layer of roofing felt and a final layer of shingles. This type of shingle is usually a three tab, asphalt shingle with a service life between fifteen and twenty-five years. Asphalt shingles are the preferred choice for most contractors because they provide great coverage for a reasonable price. However, many homeowners look for other options when it comes time to replace it.
Roof coverings such as composite shingles, steel roofing and fiber-cement provide the homeowner with a longer lasting roof. Composite shingles are also made from asphalt, but the shingle has multiple layers that give the product more depth. The typical composite shingle has two or three layers and is often used to simulate a slate roof. This is because the shingle is thick and has unique outer edges. Most manufacturers warranty composite shingles for the life of the home.
Alternatives such as steel roofing and fiber-cement also have long warranties. Most steel roofing is warranted for a minimum of fifty years while fiber-cement tiles average thirty to thirty-five years. There are benefits to both choices, but steel may be your best bet. For instance, if the roof is simply aging it may be possible to install steel roofing over the existing asphalt. This technique requires the Roofer in Johnston to place battens over the existing shingles in order to secure the steel in place. One benefit that this technique provides is additional airflow around the roof. To learn more about roofing options click to investigate.
