Flat & TPO Roofing in Leander, TX

What's Included in Our Flat & TPO Roofing Service

Low-slope roofs fail differently than steep roofs, so they have to be built differently. We install and restore flat roofing systems that drain properly, seal at the seams, and reflect the Central Texas sun.

A flat or low-slope roof is really a continuous waterproof membrane, not a field of overlapping shingles. That means the seams and the flashing details are everything. We install single-ply TPO, modified bitumen, EPDM rubber, and built-up systems, and we choose the one that fits your building, your budget, and how the roof drains. Depending on the project, the work can include:

• Tear-off or recover of the existing membrane and inspection of the deck below
• Mechanically fastened or fully adhered single-ply TPO with hot-air-welded seams
• Multi-ply modified bitumen or built-up roofing for high-traffic and heavy-duty roofs
• EPDM rubber membrane for simple, durable low-slope coverage
• Tapered insulation and crickets to correct slope and eliminate ponding water
• New flashing, edge metal, drains, scuppers, and curb details
• Fluid-applied silicone or acrylic coatings as a restoration on sound membranes

Common Problems With Flat Roofs

Most calls we get on low-slope roofs trace back to the same handful of issues. Ask for a free inspection if you see any of these:

• Ponding water that sits for more than 48 hours after rain
• Open, split, or lifting seams where two sheets of membrane meet
• Blisters or bubbles in the membrane from trapped moisture or heat
• Cracked or alligatored built-up or modified bitumen surfaces
• Failed flashing at parapet walls, curbs, drains, and roof penetrations
• Interior leaks and stains that show up far from the actual entry point
• A dark, heat-absorbing surface driving up summer cooling bills

Our Flat Roofing Process

1. Free Inspection & Moisture Check

   We walk the roof, check every seam and drain, map ponding areas, and confirm whether the deck and insulation below are dry.

2. System Recommendation & Written Estimate

   We recommend the right membrane or coating for your building and drainage, then put the scope and price in writing with no pressure.

3. Installation

   Our crew tears off or preps the surface, corrects the slope, welds or adheres the new membrane, and details every flashing and drain by the book.

4. Water Test & Final Walkthrough

   We check drainage, confirm the seams are sealed, clean the site, and walk the finished roof with you before we leave.

Flat Roof Material Options

The right membrane depends on your building, foot traffic, budget, and how the roof drains. Here is how the three systems we install most often compare.

System	Best for	Strengths & lifespan
TPO (single-ply)	Most homes and commercial buildings wanting a reflective, energy-smart roof	Welded seams, bright white reflective surface, lower cooling load, 20 to 30 years
Modified bitumen	High-traffic roofs and decks needing a tough, multi-layer surface	Thick, puncture-resistant, proven track record, roughly 15 to 25 years
EPDM (rubber)	Simple, large low-slope roofs on a budget	Durable rubber membrane, flexible in temperature swings, 20 to 25 years, darker surface absorbs more heat

If your existing membrane is still sound but tired, a fluid-applied silicone or acrylic coating can be the smartest move. A coating seals the seams, stops minor leaks, and adds a reflective white layer that lowers cooling load, all for far less than a full tear-off.

What Affects the Cost of a Flat Roof

Flat-roof pricing is driven by the system you choose and the condition of what is already up there. The main factors are:

• Membrane type and thickness, since heavier mil TPO and multi-ply systems cost more
• Square footage and roof access, especially on commercial and multifamily buildings
• Tear-off versus recover, and whether wet insulation or decking must be replaced
• Drainage corrections like tapered insulation, crickets, new drains, or scuppers
• Number of penetrations and curbs that each need flashing and detailing
• Restoration versus replacement, since a coating costs a fraction of a new system

Flat Roofing Built for the Central Texas Climate

Low-slope roofs in Leander face a punishing combination of conditions. Summer surface temperatures bake dark membranes while attics and interior spaces below can climb past 150 degrees, which is exactly why a reflective white TPO or coated surface pays off here. Spring hail, common across Central Texas, dents soft membranes and tests every seam. Sudden downpours overwhelm shallow slopes and clogged drains, leaving ponding water that hammers the membrane. We build for all of it with reflective surfaces, generous drainage, and Hill Country code-compliant flashing and edge metal.
