Tamko Home Additions & ADU: The Fort Worth Owner’s Guide
If you’re looking for a Tamko home addition or ADU in Fort Worth, you’re likely staring at a roof or siding product that’s failing and wondering if the whole addition needs rework, or whether it can be saved. Most Fort Worth owners discover the problem after a hailstorm or a hard summer: curled shingles, lifted flashing, water staining at the eaves, or siding that’s buckled and pulling away from the framing. A full addition or ADU with Tamko roofing and siding runs $45,000 to $130,000 in this market depending on square footage, whether we’re tying into existing structure, and what’s hidden once we open the walls. We stock Tamko-compatible materials on the truck and can typically get eyes on your addition within 48 hours. Sawyer Remodel Fort Worth is an independent contractor, not affiliated with Tamko, but we install their product lines regularly and know where they fail first in Texas weather.
Which Tamko Models This Applies To

Tamko makes two product families that show up on Fort Worth additions and ADUs: Heritage and Titan XT asphalt shingles for roofing, and the Envision composite decking line if your addition includes a second-story deck or covered porch. The gotcha most owners hit is assuming any Tamko shingle matches any Tamko shingle. Heritage shingles are a standard architectural profile, three-tab width, around 240 pounds per square. Titan XT is a heavier, high-wind shingle rated for 130 mph and up, with a different nail line and wider exposure. If your addition was roofed with Titan XT and a repair crew patches it with Heritage, you’ll see the mismatch from the street, and the warranty won’t apply. Check the underside of a lifted shingle for the ink stamp, or look at the original invoice for the exact SKU. For Envision decking, measure the board width. Envision runs 5.5 inches wide in the standard profile. Some contractors substitute a 5.25-inch board from a big-box store, and the gap between boards reads wrong on a second-story deck.
On the OEM versus aftermarket question: for structural components like roof decking, underlayment, and fasteners, quality aftermarket equivalents from GAF or Owens Corning accessories work fine and save money. For the Tamko product itself, particularly Titan XT, we recommend staying OEM. The wind-rating depends on the shingle’s sealant chemistry and nail-line placement, both of which are proprietary to Tamko, and aftermarket “equivalents” don’t carry the same Texas Department of Insurance windstorm certification that matters in Tarrant County.

Signs Your Tamko Home Addition & ADU Is Failing
- Granule loss collecting in gutters or at downspouts. A new shingle sheds some granules in year one; a ten-year-old Tamko roof that’s dumping granules like sand means the asphalt layer is oxidizing. In Fort Worth’s UV and hail cycles, this accelerates fast once it starts.
- Curling or lifting shingle edges along the west-facing slope. That’s not just cosmetic. Texas afternoon sun bakes the adhesive seal strip until it loses grip. Wind then catches the edge and peels shingles back, letting water ride under the course.
- Water staining on the ceiling or wall where the addition ties into the original house. The tie-in valley is the first place Tamko roofs leak. If the flashing wasn’t replaced when the shingles were, or it was step-flashed wrong, you’ll see it on the interior before the roof looks bad from below.
- Expanding gaps between Envision decking boards or screws that won’t stay seated. Composite decking moves more than wood in Texas temperature swings. If the framing below has started to flex, the boards telegraph it. Standing water on the deck surface after rain is another tell that drainage pitch has failed.
- Siding or fascia that’s soft when you press it, or paint that blisters in a vertical line. That’s water getting behind the envelope. On a Tamko addition, it usually traces back to missing kickout flashing at the roof-to-wall junction. By the time you feel softness, the sheathing underneath is already compromised.

AfterReplacement Cost & What’s Included
For a Tamko home addition or ADU in Fort Worth, you’re looking at $45,000 to $130,000 all-in. That’s not a parts page price; that’s the installed reality of a project that involves framing, roofing, siding, insulation, and finishes. If the failure is limited to the roofing or decking layer, a re-roof or deck resurface on an existing addition runs materially less, often in the $8,000 to $20,000 range depending on squares and pitch. What drives the full-project number: whether the existing foundation can carry an ADU or whether we’re pouring piers, whether the tie-in to the existing house requires structural engineering, and whether the insulation and window package needs to meet Fort Worth’s IECC 2021 energy code or just current conditions. Every bid from us includes a written line-item breakdown before work starts. The number you approve is the number on the invoice. No change orders unless you ask for a change.
DIY or Call Us?
You can safely inspect your Tamko product yourself. Walk the perimeter, check gutters for granules, look for lifted shingles, press on fascia boards. That tells you the scope. What you shouldn’t do is get on a ladder and start pulling shingles or unscrewing Envision boards near the edge of a second-story deck. Falls from one-story height put people in the ER every spring in Fort Worth, and opening up the envelope without knowing what’s underneath risks turning a $2,000 patch into a $20,000 structural issue. If the framing or sheathing has begun to rot, that’s a structural repair, not a parts swap. If you’re seeing any of the signs above, call us at (682) 841-6652 and we’ll come do a proper inspection. The inspection cost comes off the job if you hire us.
FAQs

A Tamko Heritage roof in Tarrant County lasts 15 to 20 years, and Titan XT can run 25 or more, but hail events and the freeze-thaw cycles in February reset that clock faster than the warranty suggests. Texas sunlight ages the sealant strip, and once shingles start lifting, the clock is running out. Call (682) 841-6652 and we’ll tell you honestly whether you’re looking at a repair or a re-roof.
Yes, if the damage is isolated, like a section of lifted shingles after a microburst or one flashing point that’s opened up. If granules are falling across the whole roof or multiple valleys are showing their felt, you’re chasing leaks and paying for labor twice. We’ll show you photos of what we’re seeing and give you the repair number and the replace number side by side before you choose.
A roof repair on a moderate-size addition is usually one to two days of work once materials are on site. A full ADU build is a different animal, typically 8 to 16 weeks from framing to final inspection depending on permitting and weather. We schedule work so you’re never waiting on a crew that doesn’t show; the arrival time is confirmed live on the day.
For common Tamko products like Heritage shingles in the Fort Worth color palette, we keep inventory on hand and on the truck. Titan XT and Envision decking we order per project, which adds 3 to 5 business days. Before you buy anything from a big-box shelf, check the specifications against your existing product. We’ve seen too many homeowners pay for the wrong shingle and end up paying twice once a crew has to pull it all off.
If your Tamko home addition or ADU in Fort Worth isn’t holding up, don’t wait until the next storm finds the weak spot. We’ll inspect it, price it in writing, and tell you exactly what’s wrong in plain English. Call (682) 841-6652 to schedule your free estimate. The work talks. We just back it up.
