Commercial Roofing in Dallas, TX

What Does Commercial Roofing Involve?

Commercial roofing covers low-slope or flat roof systems on offices, warehouses, retail spaces, and apartment buildings. Unlike residential sloped roofs, commercial roofs rely on seamless membranes, metal panels, or built-up layers to shed water. We install, repair, and replace these systems using materials rated for Dallas's extreme sun and storm conditions.

Materials and Methods We Use

TPO (Thermoplastic Polyolefin) 60-80 Mil Thickness

TPO is our most common single-ply membrane for Dallas commercial roofs. The 60-80 mil thickness resists UV radiation degradation, which is critical in our intense sun. We heat-weld seams to prevent thermal cycling separation and cracking. Costs range from $5.50 to $8.50 per square foot installed.

EPDM (Ethylene Propylene Diene Monomer) 45-90 Mil

EPDM rubber roofing handles ponding water and hail impact well. We use 45-90 mil sheets, fully adhered or ballasted. This material withstands thermal cycling but requires careful seam sealing. Installation runs $4.50 to $7.00 per square foot.

Metal Standing Seam with Kynar 500 Coating

For pitched commercial roofs, we install standing seam metal panels with Kynar 500 finish. This coating resists fading and rust streaks along roof edges and flashing. Metal roofs last 40+ years and cost $8.00 to $12.00 per square foot.

How Much Does Commercial Roofing Cost in Dallas?

Costs depend on size, material, and complexity. For a typical 5,000-square-foot commercial roof, you'll pay $25,000 to $55,000 for TPO, $22,000 to $35,000 for EPDM, or $40,000 to $60,000 for metal. We provide free estimates with line-item pricing for removal, deck repair, and disposal.

Signs You Need Commercial Roofing Services

Visible Water Stains on Interior Ceiling Tiles

Brown or yellow stains on ceiling tiles indicate a leak above. We locate the source using infrared scans, then repair or replace damaged membrane sections.

Ponding Water Visible After Heavy Rainfall

Water that sits for 48+ hours stresses the roof deck and accelerates membrane degradation. We add tapered insulation or crickets to improve drainage.

Membrane Blistering or Bubbling in Patches

Trapped moisture under TPO or EPDM creates blisters. We cut out affected areas, dry the substrate, and patch with new material.

Rust Streaks Along Roof Edges and Flashing

Rust on metal flashing or panels signals corrosion from standing water or chemical exposure. We replace flashing and apply rust-inhibitive primer.

Hail Damage Punctures Metal Panels and Creates Pooling Areas

Dallas hailstorms dent metal panels and puncture single-ply membranes. We inspect after every severe convective storm and file insurance claims for you.

Wind Uplift at Edges from Severe Convective Storms

High winds peel back membrane edges or loosen metal panels. We re-adhere edges with enhanced fastening patterns per latest IBC standards.

The Commercial Roofing Process Step by Step

Step 1: Free Inspection and Load Analysis. We assess your roof's condition, measure slope, and check for structural issues. For roofs over 5,000 sq ft, we coordinate with a structural engineer for certification.

Step 2: Material Selection and Permitting. We help you choose TPO, EPDM, or metal based on budget and lifespan. We pull permits from Dallas building department and submit wind uplift calculations.

Step 3: Tear-Off and Deck Repair. We remove old roofing, inspect the deck for rot or rust, and replace damaged sections. This takes 1-3 days for a 5,000-sq-ft roof.

Step 4: Membrane or Metal Installation. For TPO/EPDM, we mechanically attach or fully adhere sheets and heat-weld seams. For metal, we install standing seam panels with concealed fasteners. Installation takes 3-7 days.

Step 5: Final Inspection and Warranty Activation. We perform a water test, check all flashings, and provide manufacturer warranty (15-30 years) plus our workmanship warranty. We clean all debris and haul away materials.

Insurance and Warranty Information

We work directly with your commercial property insurance for storm damage claims. Our workmanship warranty covers leaks from installation errors for 5 years. Manufacturer warranties on TPO and EPDM range from 15 to 30 years, depending on thickness.

Local Dallas Considerations

Extreme heat accelerates membrane degradation and requires reflective coatings. We use white TPO or EPDM to reduce cooling costs. High wind speeds in Gulf coastal areas demand enhanced attachment at edges and corners. Heavy rainfall creates pooling risk on low-slope commercial roofs, so we design drainage systems with multiple scuppers and internal drains. All work meets Dallas building codes and TDLR requirements.
