An asphalt shingle roof that looks wavy or rippled is something you might want to be on the lookout for on your property. Apart from its appearance ruining your home's curb appeal, it can also indicate other things, including potential roof damage.
Wet Underlayment
Underneath your shingles is the underlayment, which is a thin, waterproof material that serves as a secondary barrier against moisture intrusion. The underlayment must remain completely dry during a roof installation before the shingles are layered over it. Otherwise, the material may start to wrinkle, causing the asphalt shingles to look uneven and bumpy instead of flat. This, however, is one mistake inexperienced roofers make during shingle roof installations.
Incorrect Sheathing Installation
Before the new roof is installed, roofers must make sure that the roof decking or sheathing is structurally sound. Made of wood or oriented strand board (OSB), the decking or sheathing covers the joist and trusses to support the rest of the roofing system, including the shingles and underlayment. If installed without taking thermal expansion into account, expect rippling to occur over time. The same can happen if the decking material doesn't have an underlayment that protects against the elements.
Imprecise Shingle Alignment
Taking the correct measurements and using high-quality shingle material matters in making sure the roof looks perfectly aligned. Without any of these, you can expect your newly-installed roof to look uneven. This won't be an issue if you work with a trusted professional like A1 Quality Roofing, Inc.
