TPO & PVC Membranes
Heat-welded seams create a monolithic, watertight surface. Great UV resistance for Houston sun and compatible with reflectivity/"cool roof" specs.
Flat & Low-Slope Roofing — Houston, TX
Professional TPO, PVC, modified bitumen, and roof coatings engineered for Houston's heat, humidity, and heavy rain. We design drainage correctly, flash parapet walls, and build durable, code-compliant systems that stand the test of time.
Built the Right Way—From Deck Prep to Final Flashings
We don't just lay a membrane. We manage drainage, transitions, penetrations, and edge metal so your flat roof stays watertight for years.
Modified Bitumen
Time-tested SBS/APP systems with multi-ply redundancy. Reliable for high-traffic areas and complex details.
Coatings & Recover Options
Silicone or acrylic coatings can extend life when substrate is sound—cost-effective maintenance with proper prep.
Tapered Insulation Plans
Custom slopes direct water to drains or scuppers to avoid ponding. We design, model, and install the taper layout.
Edge, Wall & Curb Flashing
Metal edge terminations, parapet caps, and curb flashings (HVAC, vents, skylights) are detailed per manufacturer specs.
Insurance-First Restoration
We document hail/wind damage, assist with the claim, and restore your roof to a code-compliant system with clean job sites.

| PVC | Grease/chemical exposure areas | Hot-air welded | Excellent chemical resistance | $$$ | Premium membranes; robust seams |
| Modified Bitumen | High-traffic roofs, complex details | Cold/torch/welded laps | Multi-ply redundancy | $$–$$$ | Great for transitions & curbs |
| Silicone/Acrylic Coatings | Life extension on sound substrates | Liquid-applied (no seams) | Depends on prep & thickness | $–$$ | Cost-effective if existing roof qualifies |
Flat Roof Replacement & Repair in Houston, Katy, Cypress & The Woodlands
Sherlock Home Roofing specializes in flat and low-slope systems—TPO, PVC, modified bitumen, and coatings—installed to manufacturer specification and local code. We design tapered insulation to move water, clean and prep the deck, weld or lap seams correctly, and terminate membranes with edge metal, parapet caps, and curb flashings that hold up to Houston weather.
Drainage Done Right
Flat roofs fail when water sits. We use drains, scuppers, and tapered plans that direct water off the roof quickly—protecting seams and extending life. After hail or high winds, we document damage and guide the insurance claim process.
Maintenance & Restoration
Annual inspections, seam checks, and penetration reseals keep membranes watertight. If your substrate is sound, a silicone or acrylic coating can restore reflectivity and extend service life. Outside of a claim, explore our financing options.

Flat Roofing FAQs — Houston Homeowners
Insufficient slope, clogged drains, or poor scupper placement. We design tapered insulation and set proper drain elevations to remove water efficiently.
Not below manufacturer minimums (typically 2/12 or 3/12). Low-slope sections need a dedicated flat-roof membrane like TPO, PVC, or modified bitumen to stay watertight.
With proper installation and maintenance, 20–30 years is common. UV exposure, foot traffic, and maintenance frequency affect longevity.
Yes—if the existing roof is dry and structurally sound. Coatings can add reflectivity and extend life at a lower cost than full replacement. We'll inspect and core-sample if needed.
Absolutely. We fabricate and install edge metal, caps, and curb flashings to manufacturer spec—critical to long-term performance.
