Chad Alphonso's Roofing and Repairs | Roofing Services in Chalmette, LA 70043

In our Chalmette climate, shingle curling is often caused by moisture absorption from our high humidity, combined with heat from the sun baking the roof. This weakens the shingle's structure. We fix it by first identifying the root cause—poor attic ventilation or aging materials—and then recommending targeted repairs or a section replacement. For widespread curling, a full roof replacement with modern, algae-resistant shingles rated for our Gulf Coast weather provides the most reliable, long-term solution.

Roof mold in Chalmette typically stems from moisture trapped under shaded, organic debris like leaves or moss, especially in our humid environment. We safely remove the growth and clean the affected area. The key to prevention is addressing the source: we improve roof drainage, trim back overhanging branches to increase sun exposure, and often recommend installing zinc or copper strips at the roof's ridge. These metals release ions that wash down with rain, creating an environment where mold and algae struggle to regrow.

Great question, and it's very common here. Those dark streaks are likely Gloeocapsa magma algae, which thrives in our humidity and can accelerate shingle deterioration, leading to curling. We treat this as one integrated job. We'll first professionally clean the roof to remove the algae biomass. Then, we assess the shingles underneath. Often, repairs or replacement are needed in the most affected areas. We can then discuss protective measures, like using algae-resistant shingles for any replacement work, to tackle both problems together for a comprehensive, lasting fix.
