Replacing your roof is a major endeavor. With that in mind, it’s understandable if homeowners are constantly looking for ways to keep costs low. Oftentimes, this is done by negotiating with roofers, doing part of the work themselves or using their insurance to lower the overall cost of the roofing project. However, apart from getting low-quality materials, there is another thing you should never do: nail a new roof over the old one.
When it comes to the question of nailing over instead of replacing your roof, no roof repair and replacement professionals worth their salt will ever recommend nailing over the old roof. In fact, two layers of shingles is the maximum amount that should be installed on a roofing system. There are also many disadvantages to nailing over your old roof; one of these is that you won’t be able to replace the ice and water shield of your roof, leaving you vulnerable to moisture damage in the long run.
Apart from the moisture concerns, another disadvantage that nailing a new roof over the old one brings is that it adds more weight to the system. This can easily compromise its structural integrity and absorb more heat, which not only shortens the roof’s lifespan, but wreaks havoc on your cooling bills as well.
