Choose your city
Louisiana's climate, with its intense humidity and frequent heavy rains, requires an asphalt shingle roof installed with meticulous attention to water shedding and wind resistance. Our installation process begins with a thorough inspection of your existing roof structure. We then remove all old roofing materials down to the deck. This critical step allows us to identify and repair any underlying rot or structural damage that could compromise the new roof's integrity.
We install a high-quality underlayment and a robust ice and water shield, especially along eaves, valleys, and around penetrations, to prevent moisture from reaching the deck. The asphalt shingles are then applied with precise overlap and secure fastening methods designed to withstand strong winds. Proper attic ventilation is also integrated to help dissipate heat and moisture, preventing mold and mildew growth. The final cost of your asphalt shingle roof installation is determined by the roof's surface area, its pitch, the specific type and quality of shingles chosen, and the extent of any necessary deck repairs.
