When it comes to roof replacements in North Carolina, you might have heard that the North Carolina State Building Code allows for up to two layers of asphalt shingles on a residential roof. While that’s true, Skyview Roofing chooses not to install a second layer of shingles—and for good reason.
Why Skyview Roofing Doesn’t Install Multiple Layers of Shingles — And Why That’s a Good Thing
The Risks of Layering Shingles
1. Increased Risk of Roof Leaks
Multiple shingle layers can hide underlying damage, making it harder to detect and repair issues. Over time, this can lead to moisture buildup and roof leaks, which may result in costly repairs. If you do not fix the original issue and choose to cover it up, this is a guarantee for future issues.
2. Excess Heat Retention
Two layers of shingles trap more heat, which can cause your attic and home to become less energy efficient. This increased temperature can also shorten the lifespan of your roofing materials.
3. Added Weight on Your Roof Deck
Extra shingles add significant weight to your roof structure. Over time, this additional weight can compromise the integrity of your roof deck, especially if it wasn’t designed to handle that load.
4. No Manufacturer Warranty
Shingle manufacturers typically won’t honor warranties for roofs that have more than one layer of shingles. That means if anything goes wrong, you’re left footing the bill.
5. No Workmanship Warranty
At Skyview Roofing, we believe in doing the right thing and pride ourselves on providing high-quality roofing services with a guaranteed workmanship warranty. However, installing a second layer of shingles doesn’t meet our standards—so we couldn’t offer our usual coverage for that type of job.
