Why Flat Roofs Leak, and How Ours Don’t
Water doesn’t run off a flat roof. It has to be drained.
The modern homes going up around Boerne and the retail and office buildings along I-10 and Main Street use flat and low-slope sections, and every one of them lives or dies on drainage. Ponding water, clogged drains, failed seams and poor flashing at parapets cause almost every flat roof failure we see.
We correct drainage with tapered insulation, heat-weld TPO seams stronger than the membrane, flash every penetration with manufacturer details rather than mastic, and tell you what to check twice a year.
- TPO single-ply membrane
- PVC for restaurants and grease exposure
- Modified bitumen (torch-down and self-adhered)
- Silicone and acrylic coatings
- Tapered insulation for drainage
- Parapet, drain and penetration flashing

Flat Roofing Systems We Install
The right system depends on traffic, exposure and how long you’re keeping the building.
TPO
White reflective membrane, heat-welded seams, 20-plus year life.
Modified bitumen
Multi-layer asphalt, durable underfoot.
Coatings
Silicone or acrylic over a sound roof adds 10 to 15 years.
Drainage correction
Tapered insulation, added drains or scuppers.
Residential flat sections
Porches, additions and modern homes, tied into pitched sections.
Commercial systems
See commercial roofing.
Coat It or Replace It?
A coating is a great investment on the right roof and wasted on the wrong one.
Sound membrane, dry underneath, simply aging: a silicone coating restores it for years at a fraction of replacement. Wet insulation beneath: coating traps the moisture and the roof fails anyway. We test for moisture before recommending either.
Flat Roofing FAQ
How long does a flat roof last here?
TPO and PVC, 20 to 30 years with maintenance. Modified bitumen 15 to 25. Coatings add 10 to 15 to a sound roof.
TPO or modified bitumen?
TPO for most: reflective in Hill Country heat, welded seams, cost-effective. Mod-bit where foot traffic is heavy or tie-ins matter.
Why does water pond on my roof?
Deck deflection, clogged drains or insufficient slope. We correct with tapered insulation or drains.
Can you fix a leak without replacing the roof?
Usually. Most flat roof leaks are at a seam, drain, penetration or parapet.
Do flat roofs need maintenance?
More than pitched roofs. Drains, seams and flashing checked twice a year. We offer programs for both residential and commercial.
