Bloomington Acrylic Roof Coating Contractor

Film thickness, slope, drainage, and cleaning quality set the life of an acrylic roof. Roofs that shed water fast get the most from it. Ponding, piled debris, and foot traffic wear it sooner, and a recoat at the right time extends it.

On clean, primed steel, acrylic grips firmly and stretches with the panels as they expand in July and contract in January. It stays bright and reflects sunlight. Low spots that hold water need a fix or a different coating in those areas.

Two or more coats reach the specified dry film thickness, often in contrasting colors so coverage is easy to confirm. Each coat dries before the next one goes on. Humidity and temperature change drying time, so the schedule leaves room for weather between coats.

Sloped metal sections that drain well take acrylic after a thorough wash, because stone dust weakens adhesion. Rusted laps and screws get primer and reinforcement. Flatter areas where water sits suit silicone better, so some mill roofs end up with both.

Water-based acrylic needs air and surface temperatures above the maker's minimum, a dry roof, and several hours without rain after application. In Indiana that means late spring, summer, and early fall, with starts after the morning dew has dried.

Acrylic sits within our coating range of about $2.50 to $4.00 per square foot, with the price set after an inspection. The amount of rust treatment, lap sealing, screw replacement, roof size, and access change where your roof falls.

Old acrylic and most factory paints accept new acrylic once they are washed and pass an adhesion test. A previous silicone coating is the exception, since acrylic will not stick to it. We cut a few test patches during the inspection to see what the old film is.
