Changing from an asphalt shingle roof to a metal roof is a viable option for most homeowners, but a lot of them are unfamiliar with how switching to a metal roof will actually be carried out. One of the most crucial decisions is choosing whether to remove the existing shingles before the metal panels are laid out. Is it necessary for roof replacement?
A Matter of Heat
One of the main reasons why experts advise removing old shingles before installing new shingles is because of asphalt’s high thermal resistance. Because the old asphalt tends to stop heat transfer, the heat is trapped between the old and the new shingles, causing wear and tear on your new roof. However, this is only true if you’re installing new asphalt shingles and not metal.
Metal Sheds Heat
While asphalt shingles are vulnerable to the trapped heat, metal roofing panels don’t suffer from the same problem. This is because metal sheds heat faster than any other roofing material available. In fact, this is also the main reason why any roofing contractor will say that metal roofs are great for homes in areas with a generally warm climate.
Other Benefits of Not Removing Shingles
Aside from saving time and effort during replacement, leaving the old shingles intact also offers a few benefits. First, the old shingles can still function as a secondary layer of protection. Next, it also means that the roof replacement will contribute less debris to be cleaned up and sent to landfills. Last but not least, the money you save not removing the tiles can be spent on getting higher quality metal panels.
Roof Work by the Pros
Whether you choose to leave your shingles intact or otherwise, you still need to have your roof estimate reviewed by a certified roofing expert to figure out how much you can potentially save on your next replacement project. Furthermore, getting your new metal roof should also be done by the pros to ensure that it is installed according to manufacturer specifications.
