Have you ever looked at a house and noticed that there was something strange going on with the roof, but you couldn't quite put your finger on it? How about your own roof? Does it look solid on the outside, but leak on the inside? Here are some hidden roof problems that need to be addressed before they become visible.
Incorrect Shingle Alignment
A quality roofing contractor such as Cottrell Bros. knows how to properly align shingles when attaching them to the roof. However, occasionally, due to a manufacturing defect or a overzealous do-it-yourself moment, the alignment between rows of shingles can be slightly off. This can cause water to seep into the cracks between the shingles and create multiple other problems such as roof leaks and warped decking. The best defense you have against this problem is to hire a skilled roofing contractor any time you need to replace a large quantity of shingles on your roof.
Over time, if there is not a proper moisture barrier between the shingles and the decking of a roof, the decking will begin to warp. This will cause the roof to look wrinkled or sag, and eventually to decay. If the whole roof has this problem, it may be that the entire roof and deck need to be replace, but if it is only in a small area, it may be possible to repair just the section of decking that has gone bad. In order to prevent this event from occurring again, make sure to use or tar or tar paper under the shingles as a moisture barrier.
A Leak With No Holes
A hole in the roof is a pretty obvious sign that you need to hire a roofing contractor, but what if you have a leak, but cannot find any holes? The problem may be due to an improperly sealed joint. This can occur at any peaks of the roof or where there are changes in the angle, such as around chimneys and dormers. It is important to find the cause of these hidden leaks quickly, and then make sure to dry any parts of the decking, rafters, and walls where the leak occurred as quickly as possible to prevent further damage. A roofing contractor can help to sure up those problem areas so that there is a tight seal to prevent future leaks from occurring.
If you see a problem with your roof, even if you are not quite sure what is wrong, have it evaluated by a roofing contractor. Getting ahead of a problem could save you a lot of time and money in the future.
