Commercial Building Reroof Project

You can definitely put a new roof over your old one, and this is typically called reroofing. However, it is always best to call for experts’ advice and rely on their knowledge and experience, instead of trying to do things on your own.

What roofers basically do is put another layer of shingles over the existing one. Because you have only two layers of shingles on your roofing system, you can only reroof it once. This process does not involve tearing off the first layer of shingles, or the inner layer, only the exterior layer, which shows signs of deterioration.

There are certain situations in which putting a new roof over your old roof can be a good idea. First of all, your roof may be in an overall good condition, with only a few signs of damage. Your shingles may lose color, granules and generally become worn out due to aging, but the interior layer is still in good shape.

At the same time, you may want to change the color or design of your roof, and reroofing seems to be the perfect choice in this case. Because of the existing layer underneath, putting a new layer of shingles can give your roof a more tridimensional look.  As is in any situation, calling professional commercial builders is a must
