Installation Errors

By applying a commercial roofing system to a deck, the installer is affirming that the deck and underlying structure are suitable for the material being installed. By attesting that the shingle manufacturer’s warranty is valid, the installer is affirming that all of the manufacturer’s conditions to make the warranty effective have been met. By performing work under a building/construction permit that references a particular building code, the installer must hold his workmanship and the entire roof system against the rigid requirements of modern codes.

Unfortunately, there are few barriers one will encounter when entering this industry, and no legal prerequisites are required to certify oneself as an experienced roofing contractor. Roof installation is hard work, and given the extreme competition and shortage of experienced labor in this industry, errors, mistakes, shortcuts, and other problems are an inevitable consequence. Installation errors, mistakes, and damages are very common in roofing, and experience suggests that human error is a bigger a cause of roof problems than all other potential culprits combined.

Donan Engineering’s team of professional engineers is experienced at studying commercial roofing systems to ensure that each product has been correctly applied. Our engineers are familiar with the challenges that a competent roofing contractor faces, and we strive to place ourselves in the shoes of the contractor when studying these roofs and interpreting how and why installation errors, mistakes, and damages occur.
