Aging and extreme weather can cause your roofing to deteriorate. In some cases, the damage can still be fixed by a roofing contractor. But in other instances where the damage is severe, roof replacement will have to be done. More specifically, a roof tear-off will likely be recommended. This means removing the existing roof, including the underlayment so that a new one can be installed in its place.
The other option is reroofing, a method that involves laying new shingles over old ones. While roofers may allow this type of roof replacement for special cases, it is still more common for them to recommend a full replacement.
In this post, Mass-Tech Roofing and Building Co. discuss the benefits of tearing off an old roof and also replacing the underlayment.
Why You Should Opt for a Tear-Off
Below are some of the major advantages of a roof tear-off:
- Tear-offs are usually required by building codes. So if you want to comply with these regulations and avoid a hefty fine and redoing your roof, it’s best to have your old roof completely removed.
- Depending on the terms of your roofing warranty, a tear-off may be stated as the recommended installation method. In this case, you’ll have to follow the manufacturer’s instructions to keep the validity of the warranty.
- A tear-off allows roofing companies to have a look at the roof decking and check it for mold, rot, or damage. The condition of the roof deck can affect the quality, performance, and longevity of the new roofing. So if you want to maximize the benefits of a new roof, you should also ensure that the other roofing components are in good shape.
- The underlayment is a material located underneath the shingles. If your shingles are already damaged or missing, there’s a chance that the underlayment has been damaged and exposed to the elements. An underlayment in poor condition should also be replaced so that you can ensure the quality of your new shingles.
When Reroofing Can Be Considered
Roofers may only recommend reroofing if the roof is old but still in generally good condition. That said, they would have to do a thorough inspection to ensure that your roof has no severe water damage, moss and mildew, and missing shingles.
