It’s common knowledge that roofs have a limited life span due to years of wear and tear, but what causes it remains a mystery for many. In this blog, roof installation contractor Kearns Brothers shares the common causes of roof wear and tear.
- High Winds — High winds are one of the leading causes of roofing wear and tear. It can lift the edges of roofing shingles, expose the underlying layers to water damage and cause stress cracks. If you happen to live in an area that’s in the path of high winds or frequent storms, invest in a roofing system rated for Category 3 or 4 hurricanes. In addition to more durable materials, such roofing systems also feature reinforced shingles and starter strips that prevent wind tear-offs.
- Rainwater — Heavy rainfall causes erosion on the roofing surface. Over time, the granules that coat asphalt shingles get worn out, exposing the backing material underneath. Quality asphalt shingles are usually warranted against granule erosion for the first 10 years or so and investing in such roofing systems may save you from problems such as unexpected roof repair, or a premature replacement.
- Sunlight — Exposure to sunlight—or, more specifically, solar heat and UV rays—is unavoidable. Nevertheless, it causes advanced aging. This is why west and south-facing roofs appear to age faster, as they’re exposed to peak amounts of sun. Cool roofs, or roofs with reflective properties, reflect sunlight to reduce heat absorption and are also less prone to succumb to premature aging from sunlight.
- Surrounding Trees — Have the trees in your yard trimmed if its branches are touching the roof surface. Sharp branches can poke the shingles and scratch the granules off it. It may even poke holes on the roof. The same branches can also give squirrels and other climbing animals easy access to your roof. Hire a local arborist to trim your trees without harming it. A 10-foot clearance should allow several years’ worth of growth before it needs trimming again.
