Flat Roofing
Low-slope roof repair, replacement and coating for homes and commercial buildings across Mesa, Tempe, Phoenix and the Valley.
Mesa, Arizona
Low-slope roofing built for Arizona sun and drainage.
Flat roofs are everywhere in the Valley — mid-century homes, additions, patio structures and nearly every commercial building. Whether water is sitting where it should drain or the surface has chalked out from years of sun, we walk the roof and photograph it before recommending a direction.
The Blackline way
The systems we work with
01
Spray foam
Applied as a liquid that expands into a seamless, insulating layer with no seams for water to find. Needs a protective coating for UV.
02
TPO membrane
Single-ply sheet, mechanically fastened or adhered and heat-welded at the seams. Reflective, durable, long service life.
03
Acrylic coatings
A reflective, elastomeric surface over foam, TPO or metal to extend the life of a roof that's still sound.

Straight talk
Why flat roofs fail here
A flat roof isn't truly flat, and everything about how it performs comes down to whether water leaves the way it was designed to. Ponding accelerates the breakdown of whatever surface is underneath.
Sun does the rest: coatings chalk and thin, membranes lose reflectivity, and exposed foam degrades quickly once its protective layer wears through.
Penetrations are the other pattern. Every vent, curb and equipment mount interrupts the field of the roof — and that's where leaks start.

Flat Roofing: common questions.
Often, yes. If the substrate is dry and sound, a coating or targeted repair can add years.
