Flat Roof Repair Services in Plano TX
Flat and low-slope roofing is common in Plano on commercial buildings, home additions, patio covers, garages, and modern architectural homes. Flat roofs require fundamentally different repair techniques than pitched asphalt shingle roofing — incorrect repairs can make problems worse and void membrane warranties.
Our team is experienced with all major flat roof membrane systems used in the DFW area, including TPO, EPDM, PVC, modified bitumen, and built-up roofing. We diagnose the root cause of flat roof failures — not just the visible symptom — and repair or replace the affected area correctly.
TPO Membrane
Most common commercial flat roof in DFW. Heat-welded seams require specialist equipment.
EPDM Rubber
Highly durable rubber membrane for residential additions and patio covers in Plano.
Flashing & Seams
Parapet wall and penetration flashing — most common source of flat roof leaks.
Flat Roof Systems We Service in Plano TX
TPO Roof Repair Plano TX
Thermoplastic polyolefin (TPO) is the most widely installed flat roof membrane in DFW commercial construction over the past 15 years. TPO is heat-welded at seams, providing strong watertight joints when installed correctly. Common failure points in Plano's heat and UV environment include seam separation from thermal cycling, membrane shrinkage pulling away from edges and penetrations, and punctures at HVAC equipment areas. TPO repairs require proper heat-welding equipment — not adhesive patches from a hardware store. We use commercial-grade equipment and materials for all TPO repairs in Plano.
EPDM Roof Repair Plano TX
Ethylene propylene diene monomer (EPDM) rubber membrane is highly durable and UV resistant — well suited to North Texas sun exposure. EPDM is the most common flat roof material on residential additions and patio covers in Plano. Common EPDM failures include seam adhesive breakdown (particularly on older installations), punctures, and shrinkage at penetrations and termination bars. EPDM repairs use either lap sealant and seam tape or cut-in patch systems depending on the failure type and membrane age.
PVC Roof Repair Plano TX
PVC (polyvinyl chloride) membrane is used in commercial applications requiring chemical resistance and high heat reflectivity. PVC is heat-welded like TPO but has different thermal movement characteristics. We service PVC roofs on commercial buildings and specialised residential applications across Plano and Collin County.
Modified Bitumen Roof Repair Plano TX
Modified bitumen (mod-bit) is torch-applied or self-adhered multi-ply asphalt membrane — a significant upgrade from traditional built-up roofing. Common on flat sections of homes built in the 1990s and 2000s in Plano. Failure modes include alligatoring (surface oxidation), lap seal failure, and flashing separation at parapets. Repair typically involves torch-applied patches, seam reinforcement, and reflective coating for UV protection.
Built-Up Roofing (BUR) Repair Plano TX
Built-up roofing — multiple alternating layers of asphalt and reinforcing fabric topped with gravel — is found on many older commercial buildings in Plano. BUR repairs require specialist knowledge of the specific ply system and surfacing. We assess the layer condition and recommend repair, recovery (adding a new layer over existing), or replacement based on the system's remaining serviceable life.
Flat Roof Replacement Plano TX
When flat roof repair is no longer cost-effective — typically when the membrane is over 15–20 years old with widespread failure — full replacement is the right solution. We provide complete flat roof replacement in Plano for all commercial and residential applications, with full specification and warranty documentation.
Common Flat Roof Problems in Plano TX
- Ponding water: Water pooling more than 48 hours after rain indicates drainage failure or settled areas — a leading cause of premature flat roof failure in Plano
- Membrane blistering: Air or moisture trapped between layers causes bubbles — indicates adhesion failure requiring investigation
- Seam separation: Heat-welded or adhesive seams failing — most common along ridges and at penetrations
- Flashing failure: At parapet walls, mechanical equipment curbs, and penetrations — the most common source of flat roof leaks
- UV degradation: Surface oxidation and cracking from North Texas sun exposure — accelerated without reflective coating
- Foot traffic damage: Punctures from HVAC maintenance and other roof access
Flat Roof Repair vs. Replacement in Plano
We recommend repair when the membrane is under 12–15 years old and damage is localised. Replacement makes more sense when:
- The membrane is over 15 years old with widespread alligatoring or delamination
- There have been multiple repairs to the same general area
- Ponding water has caused significant membrane compression and substrate damage
- The substrate (insulation and decking) has been repeatedly wetted — moisture damage to the roof assembly
Flat Roof Repair FAQs — Plano TX
How do I know if my flat roof needs repair or replacement?
A professional inspection is required to assess membrane condition, substrate integrity, and drainage performance. We provide free flat roof inspections with no obligation.
Can you repair TPO and EPDM roofs on residential properties?
Yes — we service both residential and commercial flat roofs in Plano TX. Home additions and attached garages with flat roofs are among our most common residential flat roof jobs.
Does insurance cover flat roof damage in Plano?
Hail damage to commercial flat roofs is typically covered under commercial property policies. Residential flat roof additions are covered under homeowner's policies for sudden storm damage. We document damage for insurance submission.
