In our local climate, the primary culprits are extreme thermal expansion and contraction from daily temperature swings and prolonged UV exposure. This constant stress can weaken seals and fasteners, causing the metal flashing to pull away from the roof edge or wall. K&T Roofing addresses this by inspecting the full perimeter, resealing with high-grade, flexible sealants, and ensuring proper fastening to prevent future separation.

Repairing expansion cracks requires more than just a patch. We first assess the underlying cause—often thermal stress or improper initial installation. Our repair involves carefully removing the compromised section, installing a new, properly sized piece of flashing with expansion joints or flexible sections factored in, and sealing it with materials designed to withstand our Arizona heat. This approach provides a long-term solution, not just a temporary fix.

Even small flashing failures are a direct pathway for water. In San Tan Valley, our occasional heavy monsoon rains can drive water through these cracks and separations with surprising force, leading to hidden rot, mold, insulation damage, and interior ceiling stains within a short time. A prompt, professional repair from K&T Roofing seals your home's critical waterproofing layers, preventing costly secondary damage and preserving your roof's lifespan.
