A client’s roof has been slowly leaking around their chimney. It is very important to remove all of the old roofing materials before installing a new roof. For a long time, it was common practice to install a new roof on top of the first or even second layer of shingles. The shingle manufacturers have since changed their stance and will no longer warranty shingles if that is done. There are a slew of issues related to installing multiple layers.
