Houston's subtropical climate with hot humid summers and mild winters beats down roofs fast. UV rays crack shingles while trapped moisture from humidity grows mildew under the surface. I see this every week on houses in Midtown and Downtown where cheap crews skipped the primer and the coating peeled after one summer.
A common failure point in Harris County stock is the lack of proper edge sealing around vents and skylights. Water sneaks in during the mild winters when people do not notice until the ceiling stains. We use a high-solids acrylic base coat followed by a reflective top coat rated for 500 percent elongation to handle expansion.
Homeowners often ask how roof coating differs from a full replacement. Coating works when the deck is still solid and leaks are few. It costs less than replacement but only lasts if the prep is done right. Skip the cleaning step and the new coat fails in the first humid season.
Why roof coating fails in Houston summers
Bad prep is the top reason coatings fail here. Contractors who skip the mildew wash or use thin material watch it blister when temperatures hit 95 degrees with high humidity. We always test adhesion on a small patch first.
