Flat Roof Installation in Houston

Ranked 38th in the Nation. Architecture-Trained Oversight on Every Flat Roof We Install.

Houston’s heat, humidity, and storm seasons put flat roofs under stress that most climates never produce. Getting the installation right from the start, with the correct membrane system, proper drainage design, and tight workmanship, affects how well the roof holds up over its service life. At Hargrove Roofing - Houston, founder Billy Hargrove’s architecture background shapes how we approach every project: material selection, system fit, and design-level quality control that most roofing contractors don’t bring to the table. We’ve served South Texas homes and businesses since 2017 and are ranked 38th in the Nation on the roofingcontractor.com Top 100 Roofing Contractors list.

Our mission is straightforward: good communication leads to great quality. That means you know what’s happening at every stage, and the work reflects it.

Signs Your Property Needs a New Flat Roof

Not every roof problem calls for a full replacement. But some conditions signal that the existing system can’t be repaired back to reliable performance. If you’re seeing any of the following, it’s worth having us take a look before another storm season arrives.

Replacement warning signs to watch for:

• Ponding water: Water that doesn’t drain within 48 hours after rain indicates a drainage or slope failure in the membrane system
• Membrane cracking, blistering, or seam separation: These are signs the system has reached the end of its service life
• Recurring leaks after repairs: When leaks return in the same areas, the problem can indicate widespread membrane failure, not isolated damage
• Soft spots or sagging underfoot: Structural softness can mean moisture has compromised the roof deck, and a full replacement is needed
• Age: Flat roof systems typically carry a service life of 15 to 30 years depending on the material; a roof approaching that range warrants a replacement evaluation
