Quality materials and a proper installation—these are the two things that make residential roofing systems last a long time. Inexperienced roofing companies, however, tend to commit installation mistakes that can render your warranty void. Here are the most common errors made by amateur roofers:
Installing new shingles over old ones is a cost-cutting measure that many “budget” installers push on their customers. With this method of installation, however, the new shingles will deteriorate early in their lifespan and the roof structure will suffer damage due to the additional load. The upfront savings might be tempting, but having your new roof installed this way can potentially void your warranty.
Roof Components from Different Companies
Pairing shingles from Manufacturer A with underlayment, hip and ridge, ice and water barrier, and other roof components from Manufacture B might seem harmless, but it will almost certainly lead to a voided warranty. Avoid this by making sure you work with expert roofers who are certified to install roofing systems from top roofing brands. This way, your new roof, components and all, will come from a single manufacturer that will stand behind every product.
Roofing systems are complex which means installing them requires skill and product knowledge on the part of the professionals. In other words, the roofs must be installed according to the manufacturer’s precise specifications. Underqualified and unscrupulous roofers who cut corners risk voiding the protection that roofing warranties are meant to provide.
Lack of Ventilation
Attic ventilation is crucial to the roofing system’s longevity and integrity. Without proper ventilation, expect problems to arise, from damaged shingles to mold growth. In time, the roof will fail prematurely, which can cost a lot to repair and will not likely be covered by warranty.
