Your roof is a significant investment, which is why getting stuck with a voided manufacturer’s warranty is the last thing you want to happen. There are several factors that can nullify your warranty, but some are more common than others. Your premier roofing contractor shares the top three today:
Improper Installation
Roofing manufacturers have strict guidelines about the installation of their roofs. This is because even with high-quality materials, improper installation can significantly shorten the lifespan of the roofing system. To ensure that you experience the full benefits of their products, manufacturers specify things like the length and number of nails used per shingle. If your roofer fails to follow these guidelines when installing your new roof, your warranty might be voided.
Excessive Pressure Washing
Moss on your roof can trap moisture on its surface. This causes premature wear on your system that can lead to increased frost damage and cracked shingle granules. To remove moss, many homeowners choose to pressure wash their roofing system. Unfortunately, doing so can damage your shingles. Close-range washing can cause your roofing granules to deteriorate and separate from the shingles. You can consult our residential roofing experts for safer alternatives to pressure washing.
Insufficient Ventilation
Proper ventilation in the attic prevents hot air and moisture from getting trapped under your roof, allowing you to enjoy a more comfortable indoor environment and improved roof performance. Heat at the bottom of your shingles can cause premature wear and tear, while moisture can wreak havoc on your roof, especially in winter. Work with a professional roofer to build a ventilation system that works for your home.
