Did you know that a seemingly minor detail like the number of shingle layers on your roof can significantly impact its lifespan and your warranty?
Many homeowners are unaware that adding new shingles over old ones can lead to a host of problems, including:
Increased Weight
Extra layers can put undue stress on your roof’s structure, potentially leading to sagging or collapse.
Poor Ventilation
Trapped moisture and heat can accelerate the aging process of your roof, reducing its lifespan.
Uneven Surface
Old shingles can create an uneven surface, compromising the seal of new shingles and increasing the risk of leaks.
Avoid Risking Your Warranty
Many roofing manufacturers explicitly state that adding shingles over existing layers can void the roof’s warranty. As mentioned earlier, this is because multiple layers can lead to increased weight, poor ventilation, and an uneven surface, all of which can compromise the integrity of the new roof. By removing all existing layers, you can ensure that your new roof is properly installed and that your warranty remains valid.
Protect Your Investment: Choose a Reputable Contractor
To avoid these issues, it’s crucial to select a reputable roofing contractor who will remove all existing layers of shingles before installing a new roof. This ensures proper installation and maintains your roof’s warranty.
