There are several things that make a roof functional. For instance, the shingles that keep out the rain are made from a bitumen material known as asphalt. Unfortunately, asphalt can dry out over time and this allows the shingles to crack and eventually, to leak. Another factor that helps the roof protect the home is the way that the roof is installed. A roof needs to be properly overlapped or water can run back under the roofing material. An expert in residential roofing in St. Charles, MO can ensure this is done properly so that the water sheds correctly.
The roof is not an install-and-forget job. In fact, the roof needs to be inspected on occasion so that no small problem results in expensive repairs. For instance, whenever there is a major storm, it is a good idea to check around the roof for signs of damage and debris. If the storm is massive, then it may be useful to have someone with experience in residential roofing in St. Charles, MO do the inspection. A small leak can easily turn into a major repair once the water begins to seep under the shingles.
The most common problem with residential roofing is a leak, but leaks can occur for many reasons. For example, a leak may be due to damage to the shingles or dried sealant around flashing or attic vents. Attempting to repair the problem can actually make things worse. Consider the faulty sealant. Placing a lot of additional sealant over the affected area may only reroute the water without actually sealing the hole.
Another concern with many roofs is old shingles. Asphalt shingles, especially budget grade versions, suffer under the heat of the sun. This allows the material to crack, which can let water enter the roof. Replacing the old shingles may seem like an expensive repair, but it could actually save money in the long run. For example, replacing the roof before water enters it can avoid damage to the decking. Decking is usually a man-made product of compressed wood and resins, typically a material known as OSB (oriented strand board). Once water saturates the wood, it begins to break down.
