Houston's subtropical climate brings intense UV exposure, high humidity, and sudden downpours that accelerate flat roof degradation. Proper coating selection matters: acrylic systems offer strong reflectivity and lower cost but require dry application windows, while silicone coatings maintain flexibility and adhesion even when applied over minor moisture. In neighborhoods like Montrose and the Heights, older modified bitumen and EPDM roofs often show alligatoring and seam separation that demand targeted restoration before coating.
Ponding water remains the leading cause of premature failure on commercial flat roofs near Downtown and Midtown. Restoration crews address this by adding tapered insulation or drainage improvements before applying high-solids coatings rated for 20-plus mils dry film thickness. Houston building codes require positive drainage on re-roofing projects, and skipping this step leads to warranty voids and repeated leaks. Edge details around HVAC curbs and parapets receive extra reinforcement with fabric and mastic to prevent wind-driven water intrusion.
Application timing is critical during mild winters when temperatures stay above 50°F for curing. Crews avoid peak summer afternoons when surface temps exceed 140°F, which can cause rapid skinning and blisters. Restoration also includes removing existing failed coatings, pressure washing to remove biological growth common in humid Harris County, and documenting existing roof conditions with photos for property records.

How it works
- 1
Roof Assessment
Technicians inspect membrane condition, seams, drains, and ponding areas across the entire flat roof surface.
- 2
Surface Preparation
Power washing removes dirt, algae, and failed coating; repairs address blisters, splits, and loose flashing.
- 3
Primer and Detail Work
Primer is applied to porous surfaces; all penetrations, curbs, and edges receive fabric reinforcement and mastic.
- 4
Coating Application
Multiple coats are sprayed or rolled to specified mil thickness with proper curing time between layers.
- 5
Final Walk and Documentation
Completed roof is inspected for uniform coverage; photos and warranty information are provided to the owner.
Pricing
Pricing depends on roof size, existing condition, and coating type; request an on-site assessment for an upfront quote.
