Seam splits, membrane punctures, failed flashing at parapets and penetrations, and leaks that show up two rooms away from where the water actually enters. Flat roof leaks travel. We trace them to the real entry point, repair it correctly, and show you photos of the fix.

For a structurally sound flat roof that's chalking, cracking, or starting to leak at seams, a silicone restoration coating is often the smart middle move: a seamless, UV-stable, ponding-resistant membrane over your existing roof at a fraction of replacement cost. High-solids silicone systems from manufacturers like Gaco and Henry are the standard for this climate because silicone is one of the few coating chemistries that tolerates standing water.

Spray polyurethane foam roofs are a Southwest specialty: seamless, self-insulating, and common on St. George homes and light commercial. But foam has a maintenance contract with the sun. Its protective coating must be renewed roughly every 10 to 15 years, or UV starts eating the foam itself. We repair bird pecks, blisters, and punctures, and recoat foam systems before the damage goes structural.

When a membrane is at end of life (widespread seam failure, saturated insulation underneath, a foam roof neglected past saving) we replace the full system. For most replacements here that means single-ply TPO or PVC membrane. The major systems in this market come from manufacturers like Carlisle SynTec, GAF, and Holcim Elevate (the former Firestone Building Products), each with different seam and thickness specs we'll walk you through.

Offices, retail, and light industrial from Bluff Street through Washington City run almost exclusively flat. We handle repairs, preventive maintenance, coating restorations, and full replacement, scheduled around your business hours, with documentation your property manager or insurer can actually use.

Water that sits more than 48 hours after a storm is degrading your membrane and voiding most material warranties. On St. George flat roofs, ponding usually traces to clogged drains and scuppers or low spots that have developed as the structure settled. We fix the drainage, not just the symptom.

A flat roof almost never fails in the middle of the field. It fails at the seams, the parapet walls, and the penetrations. Thermal cycling here is brutal on seam adhesives and old flashing details. Most "mystery leaks" on flat roofs are a seam or a flashing detail doing exactly what aged seams do.

Run your hand across an aging coated roof here and it comes back white — that's the coating sacrificing itself to the sun. Chalking is normal; chalking through to exposed membrane or foam is a countdown. Caught in time, it's a recoat. Ignored, it becomes a replacement.

Exposed foam is soft foam: birds peck it, hail pits it, foot traffic crushes it, and UV crumbles it. The repair window on foam is generous if the coating is maintained and unforgiving if it isn't. If your foam roof hasn't been recoated in over a decade, an inspection is overdue.

July through September, a flat roof has to shed a month of rain in an afternoon through a handful of drains. Debris that sat harmlessly all spring becomes a dam in the first big cell. Pre-monsoon inspections exist for exactly this reason.

Flat roofs collect bad patches: roofing cement smeared over a seam, incompatible coatings layered on each other, a shingle-guy fix on a membrane roof. We see them constantly, and part of every inspection is telling you which old repairs are holding and which are the next leak.
