If you’re concerned about the condition or appearance of your roof, ask your contractor about reroofing. This is the process of applying new materials—such as asphalt shingles—over the existing rooftop. This may be a viable option in some cases, but it’s often safer and more cost-effective to invest in new roof installation. Here are three reasons to avoid adding a second layer of residential roofing.

Why a New Roof May Be a Wiser Choice

1. Heavy Weight

The addition of more weight to any size roof can be problematic. In many cases, the structure isn’t strong enough to handle the additional strain. This can pose a safety threat to the home, especially during heavy rainfall or the occasional snow or ice. The moisture adds to the weight and puts a burden on the bottom layer to support everything. Too much could eventually cause breakage and leakage.

2. Damage Issues

It’s not safe to install a new product over an old material if the previous surface is in poor condition. This could be the case if there’s damage to the underlayment due to years of widespread water damage or if it hasn’t been properly maintained during that time.

Since this type of situation requires extensive repairs to the base layers, contractors will not install fresh materials on top. In this case, a new roof installation is the only viable solution.

3. Uneven Appearance

Unfortunately, not all rooftops hold up well over the years. Systems that are especially old may be subject to shifting and movement due to inclement weather conditions, including rainfall and heavy winds.

As the shingles move out of place, they create an unsteady and uneven surface that doesn’t provide a safe or sufficient canvas for a new layer. This will make it difficult to secure the fresh shingles, which in turn leaves it vulnerable to issues like water damage and breakage.

This also applies to roofs that have already had a second layer added in the past—a third layer is not allowed, per residential roofing building codes.
