What are the Cons?
One of the biggest problems with these shingles is that they are very heavy. This is something that can slow the installation process down, especially when you are working by yourself. The more help that you have, the faster and easier installation will be for you. Something else that you are going to have to be careful of during installation is when you are cutting the shingles. The shingles will give off a dust that can be very dangerous to inhale. The dust is called silica and can cause serious illness. However, once you have cut the shingles and the dust has had time to settle the risk of this dust is gone forever.
