One of the most common questions homeowners ask roofing contractors about is whether to remove old shingles before installing a metal roof. You have two options: have them removed or leave them as they are, providing local codes allow it.
Installing Metal Roofs Over Existing Shingles
There have been numerous metal roofing installations in which metal panels or shingles were applied over old asphalt shingles. In addition to being cost-efficient, this roofing method is possible because the new material weighs less than standard shingles, reducing the amount of weight being added to the entire roof structure because of how the asphalt shingles lose a great deal of weight due to granule and oil loss over time.
The Benefits of Installing Metal Over Asphalt
For residential roofing pros, a notable advantage of installing metal panels over asphalt roofs is that this won’t affect the durability or finish of the material. The same can’t be said for new asphalt shingle installations. Apart from the added weight and the fact that it may void the manufacturer’s warranty, the new shingles’ lifespan could be shortened because of heat building up underneath the new layer.
Another great thing about installing metal panels or shingles over old asphalt shingles is that you’re not only saving money on this project, but also preserving the environment by not contributing to construction waste that ends up in landfills. Your chosen roofing contractor, however, may have to inspect your old shingle roof first to see if it has any obvious and hidden issues that need to be addressed. Removing the old shingles completely is possible depending on the extent of the damage detected.
