Why Mercer Roofing Co Dallas Is Glenn Heights’s Preferred Roof Installation Company
Glenn Heights sits in a weather spot that punishes bad roofing work. We’ve torn off enough hail-battered shingles here to know the difference between a roof that merely looks installed and one that’s installed to hold. The homes are mostly single-family brick veneer and siding from the 1970s through the 2000s, and many original 3-tab roofs have passed their usable life. Homeowners here don’t need a sales pitch; they need a crew that understands wind-driven rain, county-level permitting, and what an insurance adjuster actually wants to see after a storm.
Our Roof Installation team arrives with a promise most roofers won’t make: you’ll know the technician’s name and see a photo before they pull into your driveway. Every Mercer technician is background-checked, identity-verified, and arrives in a clean, marked uniform with a photo ID badge. That’s the Threshold Verified standard, and we hold every independently owned location to it. For a homeowner in Glenn Heights who is often alone, or has young kids, or just wants proof of who’s at the door, that badge is the reason they call us again.
We’re part of the Threshold Group family, founded in 2000, and every roof we install carries the 365-Day Done Right Promise. If the work isn’t right within a year, we make it right. That guarantee is written, not spoken. And dispatch and scheduling are coordinated from our Dallas-Fort Worth office, with crews serving Glenn Heights locally.
Styles & brands we work with






Roof Flashing Installation in Glenn Heights
Roof Flashing Installation in Glenn Heights is the part of the job that keeps water out of the places water always finds: valleys, chimneys, skylights, and wherever a roof meets a wall or vent pipe. Flashings are the metal pieces that direct water away from those joints. When they’re installed wrong or left off entirely, the roof leaks from day one, even if the shingles look fine.
What Flashing Work Includes
A proper flashing install covers step flashing along sidewalls, counter-flashing where needed, pipe boot replacement, and valley metal. On a typical Glenn Heights re-roof, we replace every piece of flashing rather than reuse old metal. Old flashing may look intact but it’s often corroded at the nail line or sprung just enough to let wind-driven rain through.
When Glenn Heights Homes Need It
Flashing fails before shingles do. If you see rust streaks below a chimney or stains on the ceiling near a skylight after a spring thunderstorm, the flashing has likely failed. We price flashing work line-by-line in the written estimate, so you’ll see exactly what’s being replaced and what it costs before we start. Expect new flashing as part of any full replacement; as a standalone repair it generally runs $450 to $1,400 depending on the number of penetrations.
TPO Roofing Installation in Glenn Heights
TPO Roofing Installation in Glenn Heights applies mostly to flat or very low-slope sections: the covered porch over a back patio, a garage addition, or a sunroom roof. TPO is a white, heat-reflective membrane that’s welded at the seams, which makes it a strong choice for the hot Texas sun. It reflects heat instead of absorbing it, which keeps those spaces cooler in July.
How TPO Works on a Glenn Heights Home
TPO is installed in large sheets, then the seams are heat-welded to form a continuous waterproof surface. That’s different from asphalt shingles, which rely on overlap and gravity. For a porch roof with a slope under 2/12, shingles are the wrong material. TPO on a typical residential porch or low-slope addition in Glenn Heights runs about $7 to $10 per square foot installed.
Hail and TPO
TPO holds up well to hail when it’s installed over a solid deck. But a poor weld or lack of proper edge termination will lift in a wind event, and then the damage starts. We inspect the existing deck and insulation before quoting, and we write what we found into the estimate. No one should weld a new membrane over water-damaged substrate.
Trusted Brands We Service in Glenn Heights
We install and repair roofs using manufacturer-recognized shingle brands, and for Glenn Heights homes we stock the lines that hold up to local conditions. We regularly install GAF Timberline HDZ architectural shingles with the manufacturer’s high-wind nailing pattern, which matters a great deal on the exposed east-facing slopes near I-35E. CertainTeed Landmark shingles are another common choice for homeowners who want a specific color match to go with brick veneer. For flat and low-slope sections, we install GAF TPO membrane. Whichever brand fits your home and budget, the price is in writing before work begins, and the workmanship carries the 365-Day Done Right Promise.

AfterCommon Roof Installation Problems We See in Glenn Heights Homes
- Wind-blown water intrusion on east-facing rake edges. Homes near I-35E with open exposure take the worst of spring storms. Without a proper starter strip and drip edge, wind-driven rain gets under the shingles and rots the decking within a few seasons.
- Water-damaged OSB from limb falls. Tree-lined lots in the older subdivisions, especially north of Belt Line Road, see more damage from falling limbs than from hail itself. A limb punctures the shingles, water gets into the OSB, and by the time anyone notices the sag, the decking is spent.
- Poorly documented permits and inspections. A cheap quote will often skip the county-specific permit process. When you go to file a hail claim, the insurer asks for proof of wind-rated installation. If you can’t produce it, the claim gets harder and the premium doesn’t improve.
- Reused flashings and bad valley details. Reusing old flashing or skipping ice and water shield in valleys saves money on the front end. It also creates the first leak after the next hard rain. We replace flashings and install full ice and water shield in valleys on every roof we install in Glenn Heights.
Pricing for Roof Installation in Glenn Heights, TX
Most full roof installations for Glenn Heights single-family homes fall between $9,800 and $18,600. That range reflects roof size, pitch, the number of valleys and penetrations, and how much decking needs replacement. A straightforward 1,600-square-foot ranch with a 5/12 pitch is going to land near the low end. A two-story with a cut-up roof, multiple valleys, and rotted OSB replacement goes toward the high end. We write every estimate as a line-item price, not a lump sum, so you can see the cost of decking, underlayment, flashing, shingles, and disposal separately. The price you approve is the price you pay. No change orders, no surprise invoices. Call (432) 302-5605 to schedule your free written estimate.

FAQs About Roof Installation in Glenn Heights
For most of Glenn Heights, your new roof should be installed to meet a minimum of 110 mph wind rating, and many insurers now want documentation that shingles were nailed per the manufacturer’s high-wind pattern. That means six nails per shingle on the high-wind zones instead of the standard four, plus a properly installed starter strip and drip edge. The rating isn’t just about the shingle; it’s about how the entire system is fastened. Call (432) 302-5605 and we’ll document every step for your insurer.
Glenn Heights straddles two counties: northern Ellis County and southern Dallas County. Each county can have slightly different wind-load requirements, inspection steps, and permit fees. That means a house on one side of Ovilla Road may fall under different rules than a house a few blocks away. Before we nail a single shingle, our team checks your exact address against the correct county’s code and pulls the right permit. That’s the only way a permit-inspected installation holds up when you file a claim.
A compliant quote includes the county permit, the scheduled inspection, full decking inspection with documented replacement, starter strip and drip edge on every rake edge, ice and water shield in valleys and around penetrations, and six-nail high-wind shingle fastening where the code requires it. A cheap quote skips the permit, reuses flashings, and doesn’t document anything. The difference shows up two ways: your roof performs differently in the next storm, and your insurance claim is handled differently after it. We write all of it into the line-item price.
Homes on the east side of Glenn Heights near I-35E sit with open exposure and take the full force of straight-line winds and hail as storms move through. Those roofs need a full starter strip, reinforced drip edge, and high-wind shingle nailing on every slope. Tree-lined lots in the older subdivisions deal less with wind shear and more with falling limbs, which means attention to decking integrity and valley protection. We inspect each roof for the failure mode that actually applies to its location, not a generic checklist.
A documented, permit-inspected, wind-rated roof gives your insurer evidence that the risk on your home is lower, and many carriers in Texas will apply a windstorm mitigation credit or better terms at renewal. That only works if the documentation exists: the permit, the inspection sign-off, the invoice showing high-wind nailing and the shingle brand, and photos from the install. We provide all of it. Without it, the insurer assumes the roof was nailed to a standard and prices the risk accordingly. Call (432) 302-5605 for a free estimate and we’ll walk you through what the documentation will look like before you sign anything.
