Understanding the Impact of Sun, Wind, and Hail on Your Roof

 

Impact of Sun, Wind, and Hail on Your Roof

Your roof is a critical part of your home’s structure and its primary shield against the unpredictable forces of nature. In the Niagara Region, with its unique climate, that means withstanding everything from intense summer sun to severe winter storms. While asphalt shingles are built to be tough, they are not immune to the slow, cumulative damage caused by exposure to the elements. Understanding how weather affects your shingles can help you spot problems early and protect your investment. 🏠

At AJT Roofing & Contracting, we are the perfect solution to all your roofing problems. We want to help you understand what’s happening on your roof so you can be proactive about its care.


The Silent Destroyer: Sun (UV Radiation) ☀️

The sun is arguably the most consistent and damaging force your roof faces. It’s a slow and silent destroyer that works year after year, even on cloudy days.

  • UV Ray Degradation: The sun’s ultraviolet (UV) rays are like tiny, persistent hammers. Over time, they break down the asphalt binder in your shingles. This causes the protective granules to loosen and fall off. Those granules are crucial because they reflect UV rays, keeping the asphalt layer below cool and protected.
  • Heat and Brittleness: The intense heat from the sun can make your shingles expand and contract throughout the day. This constant movement puts stress on the material, leading to cracking, curling, and brittleness. You may not see the damage right away, but this process makes your shingles more vulnerable to other weather events.

What to Look For: Patches of missing granules, faded shingle color, or shingles that look cracked or curled at the edges.
