3 Things To Consider Before Installing a Second Layer of Shingles

ROOFING SERVICES IN BENTONVILLE, AR

Installing new roofing at your Bentonville, AR business can be a complex endeavor. One of the big questions is whether or not it is okay to install the new roofing over the old shingles. There are several key factors to consider in making this decision.


1. Know the condition of the old roof.

The condition of the current roof is very important. If there is curling or other damage, it is best to remove the existing roofing before installing the new material. Shingling over the existing roofing will not fix leaks. Also understand that both layers of roofing have to be asphalt shingles. Other roofing materials cannot be double-layered. If the original layer is in good condition, a second layer can add extra protection. For example, if a shingle from the top layer detaches during a storm, the original shingle will still be underneath.


2. Understand local building codes.

Many areas only allow a home to have at most two layers of roofing because many structures cannot support the weight of three or more layers. Some localities may only allow a single layer. Check your roof and local ordinances to determine whether or not you are eligible to add another layer of roofing.


3. Consider whether you plan to sell your your property.

Sometimes business owners hope to increase the value of their property by re-roofing it before selling. Unfortunately, this does not always go as planned. Many inspectors will inform prospective buyers of two-layer roofs due to problems that may occur down the road. When the new owners have to replace the roofing, they will have to remove both layers. This will cost them more and may deter some potential buyers.

Roofing can be a complex task. From deciding whether to add another layer of shingles to installing the material, an experienced roofing company can help you with all your roofing needs.
