Call (903) 499-4441 to schedule a free estimate.
We know Seagoville’s roofs block by block. The 1960s ranches off Kaufman Street have different bones than the 2000s subdivisions east of Highway 175. That matters when hail hits. When you call our Roofing Company team, you get a crew that understands both eras of construction, not a salesperson reading from a generic checklist.
Why Brennan Roofing Co Dallas Is Seagoville’s Preferred Roofing Company Company
Homeowners in Seagoville keep our phones ringing for one reason: we put the price on paper before any work starts, and it does not move at the door. That practice alone sets us apart in a market where too many roofers quote low, start tearing off shingles, then hand over a change order the size of a car payment. Travis Oakley runs this crew to a defined standard, and that standard does not bend depending on the neighborhood.
Our response time to Seagoville is predictable because we keep crews staged across the southeast Dallas County corridor. A live person answers every call, around the clock. No voicemail, no callback queue, no automated system. When a hail storm pounds the north-facing slopes along Malloy Bridge Road, you get a real person on the phone who can schedule a damage inspection, not a robot that promises to return your message.
Seagoville customers also get the 365-Day Done Right Promise in writing. If a repair or installation fails within one full year, we come back at no charge. That is not a marketing line. It is the Garrison Standard, and it is printed on every contract we hand a homeowner in Seagoville.

Roofing Contractor in Seagoville
A roofing contractor in Seagoville has to diagnose failure risks differently block by block, because the city’s housing stock splits sharply between 1960s-1980s ranches and 2000s subdivisions. On the older homes, you are usually looking at original 15-pound felt and 3-tab shingles over solid board decking. On the newer builds, you have architectural shingles on lightweight trusses that can struggle under wind uplift. A contractor who treats both the same will miss problems that cost you thousands later.
Decking and Underlayment Inspection
On a 1972 brick veneer ranch near Kaufman Street, our crew found the original 15-pound felt had dried and cracked under the north-facing slope, letting water into the decking. We tore off the 3-tab shingles, replaced rotted decking boards, and installed GAF Timberline HDZ architectural shingles with a full synthetic underlayment, new drip edge, and ice and water shield in the valleys. We documented every surprise with photos and got the homeowner’s written approval on the change order before we touched the damaged wood. That is the discipline a Seagoville roof demands.
Flashing and Valley Seals
Heavy spring rains in Seagoville expose weak flashing joints and valley seals fast, especially where old metal meets shingles. We replace every flashing junction during a re-roof, not just the visible sections. The valleys get ice and water shield. The pipe boots get new collars. The chimney gets fresh step flashing. Skipping these details leaves your new roof leaking in the first storm.
Commercial Roofing in Seagoville
Commercial roofing in Seagoville runs a different playbook than residential work. Flat and low-slope systems on the warehouses and retail buildings along Highway 175 and Malloy Bridge Road take a beating from North Texas heat that climbs past 100°F in July and August. Thermal cycling cracks membranes, splits seams, and pulls flashings loose over time. A commercial re-roof here typically runs $6.50 – $11.00 per square foot installed, depending on the system and deck condition.
Flat Roof Systems
Most commercial buildings in Seagoville use TPO, EPDM, or modified bitumen systems on low-slope decks. Each has different failure modes in our climate. TPO membranes can shrink and pull at parapet walls after years of thermal cycling. Modified bitumen tends to crack at seams near HVAC curbs. We inspect the field seams, the penetrations, and the drainage before recommending a repair or replacement, and the price goes on paper first.
Hail and Wind Damage Assessments
Commercial roofs in Seagoville get hammered by the same spring hailstorms that shred residential shingles, but the damage looks different. Membrane punctures, crushed insulation under the membrane, and lifted edge metal are common. We document everything with photos and provide a written scope with line-item pricing. No vague allowances. No surprises at the end.
Trusted Brands We Service in Seagoville
We install materials from manufacturer lines homeowners in Seagoville ask for by name: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That means we do not push one brand because it carries the best margin. We explain the real differences between architectural shingles from GAF and CertainTeed, or mineral-surfaced roll roofing from Tamko, and let you choose with confidence. Parts for common Seagoville roof types stay stocked locally, which shortens turnaround after a hail damage claim gets approved.
Common Roofing Company Problems We See in Seagoville Homes
- Cracked 15-pound felt on 1960s-1980s ranches. The original underlayment on these homes dries out, cracks, and lets water reach the decking even when the shingles above look fine from the ground.
- Lightweight truss uplift on 2000s subdivision roofs. Architectural shingles over lightweight truss systems can lift during straight-line winds, especially if the original install skipped enough fasteners at the eaves and gables.
- Rosettes of missing shingle tabs on north-facing slopes. Hail hits hardest against the prevailing wind, which means the north slope of most Seagoville homes takes the worst damage in a storm.
- Flashing failures at valleys and pipe boots. Spring rains pour through old metal-to-shingle junctions that were never replaced during the last re-roof, often on homes that got a cheap overlay job years ago.

FAQs About Roofing Company in Seagoville
How do I know if my Seagoville roof’s decking needs replacement before a re-roof?
You cannot know for certain until the shingles come off, which is why a tear-off and decking inspection is the only honest way to price a Seagoville roof. Our crew checks every decking board from the attic side before we sign the contract, looking for water stains, soft spots, and sagging between rafters. Once the old shingles are off, we confirm what we found and get your written approval before replacing any decking. Call (903) 499-4441 for an inspection.
What’s the code requirement for underlayment and ice and water shield when a permit is pulled in Seagoville?
Current code in Seagoville requires synthetic or #30 felt underlayment across the field and self-adhering ice and water shield in the valleys and at eaves where ice damming is a risk. Older homes built before these requirements often have 15-pound felt, which fails faster. Any permitted re-roof we perform meets or exceeds the current standard, and we pull the permit ourselves as part of the job.
My 1978 ranch has original 3-tab shingles and 15-pound felt. Can you just go over them?
We will not go over them. Layering new shingles over cracked 15-pound felt and aging decking hides problems and cuts the new roof’s life short. The right move is a tear-off, a decking inspection, new synthetic underlayment, and new drip edge. That is the only way to see what is actually under the old shingles before you sign a contract.
Why do north-facing slopes in Seagoville lose more shingles after a hailstorm?
Hailstones in our storms drive hardest against the prevailing wind, which hits the north slope of most Seagoville homes first and with the most force. That slope loses more shingle tabs, and damage there often signals deeper bruising to the mat underneath. We inspect the north side first on every hail damage call in your neighborhood.
My 2005 subdivision home uses architectural shingles but they lift in strong winds. What’s failing?
The shingles themselves are usually fine. The failure is almost always in the fastening pattern on the lightweight truss system underneath. Many 2000s-era Seagoville subdivisions were built fast, with fewer nails per shingle than wind uplift standards call for. Our repair involves re-fastening the affected area and, in severe cases, upgrading the edge fastening at the eaves and gables. Call (903) 499-4441 for a precise quote.
