As summer heat intensifies, strong sunlight and extreme temperature shifts are silently impacting the safety and comfort of your roof. For many buildings, the roof is more than just a shield from wind and rain — it’s a vital barrier that helps regulate indoor temperature and energy efficiency. As a professional provider of roofing underlayment products and services, we remind all property owners: summer is the critical time for roof maintenance.

Three Major Summer Challenges for Roofs:

• · Thermal expansion accelerates material aging
  Hot days and cooler nights create frequent expansion and contraction cycles, which stress roofing materials and often lead to cracks, bubbling, or surface damage.
• · Strong UV rays weaken waterproof layers
  Prolonged exposure to intense sunlight can cause traditional waterproofing layers to lose flexibility, crack, and develop leak points.
• · Sudden thunderstorms increase drainage pressure
  Frequent short, heavy summer storms can overwhelm drainage systems. If gutters and downspouts are blocked, water can accumulate and lead to backflow or leakage.

Summer Roof Maintenance in Three Steps:

✅ Inspect underlayment and waterproofing layers
A quality roofing underlayment is key to withstanding heat and moisture. Check for signs of aging, cracking, or detachment — and replace damaged sections promptly.

✅ Clear out gutters and downspouts
Leaves and debris can block drainage paths. Regular cleaning helps prevent ponding and water backup issues.

✅ Assess insulation and ventilation systems
The hotter your roof, the harder your building works to stay cool. Proper insulation paired with a well-functioning ventilation system reduces energy costs and improves comfort.
