As climate change intensifies, extreme heatwaves have become the new normal during summer months. For roofing professionals and property owners alike, high temperatures pose serious challenges—not just for materials, but also for on-site safety and energy efficiency. The question is: how can modern roofing systems stand up to the heat?

Top 3 Challenges Roofs Face During Extreme Heat

1. Material Deformation and Aging
   Traditional felt underlayments can soften, melt, or crack under prolonged sun exposure, reducing the roof’s durability and performance.

2. Worker Safety Risks
   Rooftop temperatures can soar 10–20°F higher than ground level, increasing the risk of heatstroke, dehydration, and reduced productivity.

3. Spiking Energy Costs
   Overheated roofing systems can raise indoor temperatures, forcing HVAC systems to work harder and driving up energy bills.

Synthetic Underlayment: A Smarter Way to Handle the Heat

✅ High Thermal Stability

Mountain Bigfoot Barrier’s synthetic underlayments are engineered with heat-resistant polymers that won’t warp or deteriorate in high temperatures.

✅ UV-Reflective Surface
Designed with a UV-reflective layer to reduce solar absorption and prevent excessive heat buildup on rooftops.

✅ Flexible and Weather-Ready

Performs reliably even during early morning or late afternoon installations, when surface temperatures fluctuate.

✅ Improved Energy Efficiency
When combined with proper insulation and ventilation, synthetic underlayments help lower indoor temperatures and boost overall energy performance.

A Commitment to Heat-Ready Roofing

“A roofing system that stays stable in extreme heat is no longer optional—it’s essential,” says the Technical Director at Mountain Bigfoot Barrier. “We design our products not only to protect roofs, but also to protect the people working on them.”

As hot summers continue to impact the construction industry, investing in synthetic underlayment built to withstand extreme conditions is more than smart—it’s necessary for quality, safety, and long-term efficiency.
