A roof layover is a roofing installation method in which a new layer of shingles is installed over the existing shingles on a roof. This method is typically used as a quick and cost-effective way to extend the life of an existing roof. However, it is important to note that layering shingles on top of existing shingles can cause problems such as moisture buildup and increased weight on the roof structure, which could lead to structural damage. Therefore, it is important to consult with a professional roofing contractor to determine if a layover is a suitable option for your roof.
It's worth noting that installing a layover on a roof can void the warranty on the existing shingles, as well as any new materials used in the layover. Most manufacturers of roofing materials have specific installation guidelines that must be followed in order to maintain the warranty on their products. If a layover is installed, it is likely that the manufacturer's guidelines were not followed and the warranty will be voided. It's also important to be aware that a layover may not be an appropriate option for your roof depending on its current condition, age, and the type of materials used.
Laying over a roof may save money in the short term but at what cost to the roof system and home? Removing old shingles is always the best option when installing a new roof. Either way, contact a local professional to give you different options to solve your current problems!
