At Exterior Pro, we believe in empowering homeowners with knowledge. A common concern we encounter is the appearance of wavy or rippled patterns on asphalt shingle roofs. While it’s easy to dismiss these as mere cosmetic issues, they often hint at deeper, underlying problems. Let’s explore the primary causes behind these irregularities and understand their implications.
The Initial Settling Period
It’s not uncommon for newly installed shingles to appear slightly uneven. However, they should settle and lay flat within a few days. If your roof has been in place for several years and you start noticing a wavy pattern, it’s a clear indication of an underlying issue. Beyond the aesthetic concerns, these buckled shingles can also be symptomatic of moisture damage.
The Role of Framing and Sheathing
The sheathing, typically crafted from plywood or oriented strand board (OSB), is affixed to the home’s frame, joists, and trusses. If installed without adequate gaps between the boards, the sheathing can cause visible ripples on the roof. These ripples often manifest at intervals of four to eight feet. Additionally, moisture exposure, either due to inclement weather or storage in damp conditions, can cause the sheathing boards to warp, leading to a rippled appearance.
The Critical Importance of Attic Ventilation
A well-ventilated attic is essential for the health of your roof. Proper ventilation ensures that moisture escapes, preventing its accumulation on the underside of the decking boards. If unchecked, this moisture can seep through, affecting the shingles and causing them to buckle. If you notice such signs, it’s imperative to consult roofing experts like us at Exterior Pro. We’ll assess the situation and enhance your attic’s ventilation if required.
Hidden Dangers of Roof Leaks
Roof leaks can be insidious. Often, they go unnoticed, especially if homeowners don’t routinely inspect their attics. The water infiltration is gradual, allowing moisture damage to set in before it becomes evident. As the water penetrates the shingles, it can remain trapped between the underlayment and decking for extended periods. This retained moisture can cause the surrounding shingles to warp, leading to a rippled appearance.
The Impact of Workmanship Quality
The quality of workmanship plays a pivotal role in the longevity and appearance of your roof. Improper stapling or nailing can lead to wavy or rippled shingles. Moreover, if these components are not installed correctly, they can become vulnerable to leaks. In extreme cases, strong windstorms can even dislodge improperly affixed shingles.
