Tamko Roofing Company in Dallas: What to Know First
We’re an independent Tamko service provider in Dallas, and we repair, replace, and inspect Tamko roofs across the metro, from Oak Cliff to Richardson. Most Tamko repairs we quote run between $450 and $2,800 depending on what failed, and we put that number in writing before any work starts. If you own a Tamko roof and want a straight answer on cost, call (903) 499-4441.
This page is for Dallas homeowners whose Tamko roof has a problem: a leak after a hailstorm, shingles blowing off in spring winds, granule loss clogging gutters, or flashing that’s pulling away at a chimney. We’ll tell you how Tamko products fail in North Texas specifically, what it costs to fix them, and how our process works. No brand fluff, no vague promises. Just what we see on actual Tamko roofs in Dallas week after week.
How Tamko Products Fail – and How We Fix Them
Tamko makes a solid shingle, but every product line has failure patterns that show up consistently in Dallas. Here’s what we find when we get on a roof and pull back the layers:
- Heritage shingle granule loss on south-facing slopes. Tamko’s Heritage line is common on Dallas homes built in the 2000s. On roofs with full southern exposure, we routinely see premature granule shedding within 12 to 15 years. The Dallas sun cooks the asphalt, the granules loosen, and homeowners notice them piling in gutters. We don’t patch granule loss; we assess whether the shingle mat is still viable. If it’s localized, we replace affected slopes. If it’s widespread, we tell you honestly that replacement is cheaper than chasing it slope by slope.
- Elite Glass-Seal wind lift at the rake edges. Tamko Elite Glass-Seal shingles, especially on homes with open eaves, catch North Texas wind at the gable ends. The sealant strip holds fine on the field, but we see corner tabs lift first at the rake. The fix is usually simple: re-seal the lifted tabs with a manufacturer-approved adhesive and double-check nailing pattern on the affected course. We don’t replace the whole field for a rake-edge issue.
- MetalWorks stone-coated steel fastener back-out. Tamko’s MetalWorks panels hold up well to hail, but we’ve pulled enough of them in Dallas to know the fastener pattern matters. When installers under-drive screws or miss the batten, the panels shift slightly, and you get a slow leak at the overlap. We reset the panel, drive new fasteners to spec, and replace the neoprene washers. This is a case where going cheap on the original install costs more later.
- Flashing failures at chimneys and skylights on Heritage II roofs. This isn’t unique to Tamko, but it’s the most common call we get on Heritage II installations in older Dallas neighborhoods. The shingles are fine; the step flashing corrodes or the counterflashing separates from the mortar joint. We replace the flashing with proper step pieces, re-bed the counterflashing, and re-lay the Tamko shingles around it. Done right, it outlasts the original install.
- Decking rot under unventilated Tamko installs. Dallas humidity plus closed attic spaces equals decking problems. On Tamko roofs over poorly ventilated attics, we find OSB delamination starting at the eaves and working up. We cut out the compromised decking, replace it to code, and before we lay new Tamko shingles we make sure ventilation is adequate. Laying new shingles over rotting decking is how you get a five-year-old roof with a leak.
Styles & brands we work with






Our Tamko Roofing Company Process
- 1
You call, a live person answers. No voicemail, no callback queue. We answer around the clock and get your address, what you’re seeing, and when we can get a technician out. We’re at (903) 499-4441.
- 2
We inspect and show you what we found. Travis Oakley or one of our background-checked, uniformed techs gets on the roof, photographs the failure, and explains it in plain language. You’ll see the granule loss, the lifted tab, the rotted decking, before any price gets quoted.
- 3
We write the price down. Before any work starts, you get a line-item written price. That number does not move at the door. No surprise add-ons, no “while we’re up there” changes. The price on paper is the price you pay.
- 4
We decide parts: OEM where it matters, quality aftermarket where it’s smart. For warranty-sensitive repairs on newer Tamko roofs, we use Tamko-branded shingles and accessories so your manufacturer warranty stays intact. For older roofs where the series is discontinued, we match color and profile with a quality equivalent and tell you exactly what you’re getting.
- 5
We do the work and leave the site clean. Uniformed techs, drop cloths, magnetic nail sweeps at the end. Your yard looks like we were never there, except the roof is fixed.
- 6
You get the 365-Day Done Right Promise in writing. Every Tamko repair and installation is guaranteed for one full year. If it fails within that year, we come back at no charge. That’s not a marketing line; it’s printed on the paperwork you sign.
What Tamko Roofing Company Costs in Dallas
Here are the ranges we quote on typical Tamko work in Dallas. These are ballparks, not bids. Your exact price depends on roof pitch, access, and what we find under the shingles, but this gets you in the neighborhood before you ever pick up the phone:
- Small repair (re-seal lifted tabs, minor flashing patch, replace a few shingles): $450 – $850
- Chimney or skylight flashing replacement on a Tamko roof: $900 – $1,800
- Decking replacement (per sheet, including re-lay of Tamko shingles): $125 – $185 per sheet
- Partial slope replacement (one roof face re-shingled with Tamko or matched equivalent): $1,400 – $2,800
- Full Tamko roof replacement on an average Dallas home: $9,500 – $16,000 depending on square footage, pitch, and tear-off complexity
What moves the price: roof height and steepness, decking condition, how many penetrations (chimneys, vents, skylights) need flashing work, and whether you’re matching an existing Tamko color that’s still in production or working with a discontinued line. Call (903) 499-4441 for a written quote. The estimate is free, and the number we give you is the number you’ll pay.

AfterWhy Dallas Homeowners Call Brennan Roofing Co Dallas for Tamko Work
We install and repair materials from GAF, Owens Corning, CertainTeed, and Tamko because different roofs need different solutions. When your house already has Tamko on it and you want it fixed right, we work within that system without trying to sell you a full tear-off you don’t need. If a replacement is the smarter call, we’ll say so. If a repair buys you five more years, we’ll say that instead.
Every Brennan Roofing job runs under The Garrison Standard: written price before any work starts, background-checked uniformed technicians on your roof, and the 365-Day Done Right Promise backing the whole thing in writing. Phones answered by a live person around the clock, not an automated system. That’s the standard, and it’s the same on a $450 repair or a $16,000 replacement. Travis Oakley has been putting roofs on across the Southwest since his days at Los Angeles Trade-Technical College, and he keeps a worn copy of the local building code in his truck. A roof either keeps water out or it doesn’t – everything else is just conversation.
FAQs
Yes, if the roof is still within Tamko’s warranty window, we use Tamko-branded shingles and accessories on the repair so the manufacturer warranty remains valid. We document everything we touch and give you a written record of what was replaced, what was used, and when.
Most current Tamko lines, including Heritage and Elite Glass-Seal, are available through Dallas distributors. For discontinued colors or older series, we match profile and color with a quality equivalent and show you a sample before any work starts. Call (903) 499-4441 and we’ll check availability for your specific Tamko color.
Most Tamko repair calls in the Dallas metro get a technician on site within 24 to 48 hours. If you have an active leak, call (903) 499-4441 and we’ll prioritize getting it tarped and stopped, then schedule the permanent fix around your availability.
If the failing area is localized and the surrounding shingles still have life, repair makes sense. If you’re seeing granule loss across multiple slopes, recurring leaks in different spots, or decking rot under the shingles, replacement is usually the cheaper long-term option. We’ll show you the condition of the whole roof when we do the inspection, not just the spot you called about.
No. The written price you get before work starts does not move at the door. If we open up the roof and find something we didn’t expect, we stop, show you what we found, and write a new line-item quote for your approval before proceeding. No unapproved add-ons, ever. That’s The Garrison Standard.
