Protecting Your Roof from Summer Sun: What You Need to Know
Your roof is the first line of defense against the elements, and during the summer months, it takes a significant beating from heat and UV rays. While we often worry about rain, snow, and wind, prolonged sun exposure can be just as damaging, especially in the warmer climates and seasonal highs of the Northeast.
Below, our roofing experts break down how high temperatures and ultraviolet (UV) rays affect your roofing system over time and what you can do to protect your investment.
1. Shingle Deterioration
UV rays break down the chemical compounds in roofing materials, especially asphalt shingles. Over time, this leads to fading, brittleness, cracking, and loss of granules. These granules are essential for protecting the shingles from further damage, and once they’re gone, the roof becomes increasingly vulnerable.
2. Thermal Expansion and Contraction
As temperatures rise during the day and fall at night, your roof expands and contracts. This constant movement puts stress on roofing materials, fasteners, and flashing. Over time, it can lead to warping, splitting, or gaps in the roofing system, allowing moisture to enter and cause structural damage.
3. Accelerated Aging
Just like your skin, roofing materials age faster when exposed to sunlight every day. Prolonged exposure to UV rays and high heat accelerates the aging process of your roof, reducing its lifespan, especially if the roof is not properly ventilated or maintained.
4. Weakened Sealants and Adhesives
Sealants and adhesives used around flashing, skylights, and vents can dry out and lose effectiveness when exposed to heat. This can compromise the roof’s waterproofing capabilities, increasing the risk of leaks and water damage.
5. Energy Efficiency Issues
Heat absorption can affect your home’s energy efficiency. A dark or damaged roof can absorb more heat, raising attic and indoor temperatures. This forces your cooling systems to work harder, increasing your energy bills.
