Roofing Mistakes That Can Void Your Warranty

Commercial and residential roofing systems are designed with specific components that need to be installed correctly. Any mistakes during the installation process can lead to roofing problems or damage. Apart from that, your roofing warranty will likely be voided as well. 

Below are some common roofing mistakes that you and your roofer should avoid so that you can keep the coverage provided by your warranty.

Installation of New Shingles Over Old Ones

This method of installation is typically offered to homeowners who want to save on roofing costs. Since the old roof does not have to be removed, roofers have less to do so labor expenses become cheaper. However, this isn’t recommended by trusted experts and roofing manufacturers because it contributes to a shorter life span for the roofing material. Although re-roofing may be allowed in some cases, make sure to check first the installation requirements from the manufacturer. This way, you can be sure you are not risking your roofing warranty.

Use of Incompatible Roofing Components

When shopping for materials to be used in your roof replacement project, it’s usually best to stick with one specific line of roofing products. For instance, if you pair roof shingles from one manufacturer with an underlayment from another, this could potentially create problems. You might not be able to maximize the performance of your new roof, or you might compromise the integrity of your entire roof system.

Failure to Create Proper Ventilation

When designing your roofing system, ensure that proper ventilation is taken into account. Experienced roofers are knowledgeable about this, so they will see to it that your attic is well-ventilated. Without adequate ventilation in your roof area, you will likely encounter problems such as buckling of the shingles, warping of the roof decking, and mold and mildew growth.
