One of the most distasteful but necessary parts of roof replacements is tearing off the old shingles to make way for the new. However, many homeowners bypass this process through shingle reroofing. Is this an effective alternative? Today, we’ll answer some important questions about reroofing to help you decide if it’s right for you!
Can You Put a New Roof Over the Old One?
Yes, and no. When it comes to installing your new roof over the old one (reroofing) is only viable for asphalt shingles. Keep in mind, there are some requirements that you should observe before choosing reroofing for your home. First, you’ll want to make sure that your old shingles provide a flat surface for your new ones to lay over. Any curled or warped shingles on the bottom layer will have ill effect on the top layer.
The next (and most important) requirement, is to make sure your roof supports can handle the extra weight of a second layer. Many houses aren’t designed to take on the additional weight and you might have to install additional supports.
Are There Any Downsides to Reroofing?
The primary benefit of reroofing is avoiding the tear off process. This convenience can save you a thousand dollars or so in the short run, but you’ll need to consider the downsides as well. For starters, any problems that you’ve had with your previous roof layer will still be present beneath the new layer. If you’ve had leaking problems in the past that were never resolved, they’ll still be there. If you are considering shingle reroofing after a hail storm, you’d be better off filing an insurance claim and getting your roof replaced.
Shingle reroofing also makes it difficult or impossible to examine the layers beneath your new shingles, such as the decking and sheathing. Shingle manufacturers’ warranties will cover roof replacement, but they won’t always apply to reroofing jobs. Finally, avoiding tear off now doesn’t mean you won’t have to do it in the future. After your second layer of shingles wears out, you’ll have to tear down two layers instead.
