Low-slope roofs (¼:12 to 2:12) are common in Houston’s mid-century modern and contemporary homes. But even a 1% slope won’t drain properly without advanced water management. At Houston Roofing & Gutters, we treat drainage as an active system—not a passive hope.

Traditional gutters and single drains fail on low-slope roofs because water moves too slowly. Advanced solutions include:

• Tapered Insulation Systems: Creates engineered slopes (minimum ¼” per foot) toward internal drains or scuppers, eliminating ponding zones.
• Siphonic Roof Drains: Uses pipe-full hydraulic action to suck water horizontally—perfect for large low-slope areas.
• Secondary (Overflow) Drainage: Code-mandated but often ignored; we install higher-standing overflow drains to prevent collapse under storm loads.
• Gutter Apron Design: Custom-fabricated with deeper profiles and anti-splash edges for slow water runoff.

We also use infrared scanning to find hidden ponding that leads to membrane fatigue, then redesign slope planes accordingly.

On a low-slope roof, water is not your friend. Smart drainage engineering turns it into a temporary visitor.

Advanced drainage solutions transform problematic low-slope roofs into reliable, long-lasting assets. Houston Roofing & Gutters delivers flat roofing systems that actually shed water.
