Roof Coating Restoration in Hoover, AL

We screen in three steps. First, a walk to find soft spots, open seams, blisters and ponding lines. Second, an infrared moisture survey at dusk, when wet insulation shows warmer than dry. Third, core cuts at the doubtful spots, so we can see what is under the surface.

A roof qualifies when the membrane is intact, the insulation is mostly dry and the deck is firm. Roofs with large wet areas do not qualify. For them, a recover or a replacement costs less over time than a coating that fails.

Hail matters too. On April 25, 2003, central Alabama took stones as big as softballs. Hail bruises can hide under an old surface. We check for them first. If bruising is found, the hail damage is repaired before any coating goes on.

Two coatings do most of the work. Silicone handles standing water. It is the better pick when a roof holds a shallow pond after rain. Acrylic is water-based and bright. It suits roofs that drain well and lets owners add a second coat later.

Rain in the Birmingham area adds up to about 56.6 inches a year, and ponding is common on flat roofs. A ponding line is the first thing we mark. If it comes from a clogged drain, we fix the drain. If it comes from a low spot, we plan a tapered build-up or choose silicone. Never coat over a drainage problem. It hides the cause and shortens the coating.

Coatings need dry, warm days and a clean surface. In central Alabama, the best windows are late spring before the heat peaks and early fall after it. Summer works if mornings are dry. Winter is the weakest season, because cold and damp slow the cure.

Storm season peaks in March and April, with a second round in November. Plan the job so it finishes before March. Start the screening in the fall, get the scope approved by January and schedule the work for the first dry stretch. If the budget year starts in July, the job slides to August or September. Either way, the cure should finish well before the next storm window.

A typical coating job runs by section. We clean, repair, prime and coat one area, then move to the next. Tenants stay in place. Rooftop units are tied in and masked. Each section is checked with a thickness gauge before we leave it.

Cost follows roof area, repair needs, coating type and thickness, and access. A coating usually costs less than a tear-off. It also avoids disposal fees and downtime. That is why owners with sound roofs choose it.

The price rises with the prep work. Open seams, bad flashings and rusted metal all need repair before the coat. We list them as separate lines, so the owner can see what is prep and what is coating.

Compare three paths in writing: repair, coat or replace. Add the likely years each buys. The lowest cost per year wins, as long as the roof qualifies. We give that comparison with the scope. If a roof is near the end, we say so and show the replacement number beside it. Warranty terms depend on the maker, and a coating may be covered only when the roof and the prep meet them.
