Flat Roof Repair for Phoenix Homes and Businesses
Flat and low-slope roofs are everywhere in the Valley, from Pueblo-style homes and additions to apartment buildings, offices and retail centers. They work well in a dry climate, but they have a weakness that pitched roofs do not: water has to be led off the roof rather than simply running down it. When the surface wears, a seam opens or a drain is blocked, monsoon rain sits on the roof and finds its way in.
Raise The Roof AZ, LLC repairs flat roofs across Phoenix, on homes and on commercial buildings. We work on foam, TPO, modified bitumen and coated roofs, and we tell you whether your roof needs a repair, a restoration coating or a replacement before anything is quoted. ROC #337745, Class CR-42, licensed, bonded and insured.
The Flat Roof Systems We Repair
- Foam roofs (SPF): Spray foam is a popular Phoenix roof because it insulates well and forms one seamless surface. Its weak point is the protective coating on top. Once that coating wears through, the sun breaks down the foam underneath. We repair damaged foam and recoat it before the damage spreads.
- TPO roofs: A single-ply membrane common on commercial buildings. Most TPO leaks start at seams, edges and penetrations, which we repair and reseal.
- Modified bitumen: A layered roll roofing used on many homes and small commercial buildings. Blisters, cracks and failed laps are the usual problems, and most are repairable.
- Coated roofs: Elastomeric and other roof coatings protect the surface beneath them from UV and water. When a coating is chalking, cracking or peeling, recoating can add years of life to an otherwise sound roof.
Common Flat Roof Problems
- Ponding water: Low spots that hold water after rain speed up wear on every flat roof system. We address the cause where we can, from blocked drains to sagging areas.
- Blocked scuppers and drains: Dust, debris and leaves collect at drains and scuppers. Once water cannot leave the roof, it backs up against parapet walls and finds a way in.
- Parapet wall and flashing leaks: The joint where the roof meets a parapet wall is one of the most common leak points on Phoenix flat roofs. We repair the flashing and the top of the wall so water is kept out.
- Worn coatings and UV damage: Years of direct sun break down surfaces that are not protected. A coating that is wearing thin is the cheapest point at which to act.
- Seam and penetration leaks: HVAC units, vents, conduit and other penetrations are frequent leak sources. We seal them and the seams around them.
- Blisters and cracks: Trapped moisture and heat cause blisters and cracking in membranes and coatings. We cut out damaged areas and repair them properly.
Repair, Restore or Replace?
Many flat roofs that leak do not need replacing. If the structure and most of the roof surface are still sound, a targeted repair or a restoration coating over the existing roof is usually the most cost-effective choice, and it avoids the disruption of a tear-off. If the roof is saturated with water, badly damaged or past the point where a coating will hold, replacement is the honest answer, and we will show you why.
