When your roof is badly damaged or has reached the end of its lifespan, replacing a few shingles won't remedy the problem. You’ll need to have a new roof made out of fresh materials installed. If your roof is irreparable, your roofing contractor may recommend a full roof tear-off as a first step.

What Happens During a Full Roof Tear-Off?

During a tear-off, a roofing contractor will completely remove your current roofing material, whether it's shingles, shakes, or tile. This will expose the decking—a solid layer, usually plywood, that sits on top of the rafters. Your roofing company will inspect the decking and rafters and repair any damaged sections. Your home is then ready for roof replacement.

Why Choose a Tear-Off?

Some homeowners decide to add new roofing right over the old roofing. However, there are disadvantages to doing this.

First, adding new roofing doesn't get rid of issues like wood rot, which can continue to weaken the new roof. This option also doesn't allow your roofing contractor to inspect the decking, which can be dangerous if the roof is starting to weaken from wear or moisture. In addition, having two layers of roofing material puts extra weight on the decking and rafters, meaning they can collapse easier and wear out quicker.

Additionally, your roofing contractor will be unable to issue a complete manufacturer's warranty if the shingle system are not installed directly on the roof deck.

Finally, a double layer of roofing traps heat and can raise your energy bill in the summer. Completely tearing off the old roof before adding a new one means you’ll have existing problems fixed, saving you money and time spent on extensive repairs later on.
