Reasons Why You Don’t Want More Than 2 Layers of Shingle on Your Roof

One of the reasons why asphalt shingles are so popular is because they are a great low cost roofing material. Asphalt shingles do a great job of stopping water leaks and last a decent amount of time. They are even very easy to work with if you want to throw down a new layer of shingle over them. Be aware though that you cannot just throw on shingle layer after shingle layer on your roof. Experts highly recommend that you don’t have more than two layers of shingle covering your roof at any one time.

Many people are not happy about this recommendation because it’s so much easier and cheaper not to have to tear off the old shingles before you put down a new layer. In this article we will give you some information as to why it’s best to follow the experts’ advice and never put more than two layers of shingle on any building or home that you own.

Many times even if you desire to put a third layer of shingles on your roof it’s actually illegal to do it. That’s because a majority of state and local building codes specifically state you can have no more than two layers of shingles on any roof in their jurisdiction. If you get caught violating a building code there are usually some hefty fines associated with that violation.
