We know the east side of town near I-35E takes the hardest hail hits because of open exposure, and we know the tree-lined streets in older subdivisions like Red Oak Creek deal with more limb damage than hailstones. Knowing which problem you’re actually dealing with changes the whole inspection. With 3-tab shingles from the 1970s and 80s now well past their lifespan, most Glenn Heights homeowners aren’t looking at a simple repair. They’re looking at a replacement that has to be quoted honestly, with real numbers for the decking underneath.

Why Mercer Roofing Co Dallas Is Glenn Heights’s Preferred Roofing Company
Glenn Heights homeowners call us because we treat the front door like the beginning of the job, not an afterthought. Every technician who rolls up to your home in Glenn Heights is background-checked, identity-verified, and arrives in a clean uniform with a photo ID badge. You get their name and photo sent to you before they show up. That’s the Threshold Verified standard, and it’s contractually required of every Mercer location. You’ll know exactly who’s walking up your driveway before they ring the bell.
Our Roofing Company crews work with the shingle brands Glenn Heights homeowners actually ask for, including GAF, CertainTeed, and Owens Corning. More importantly, we stock fasteners, flashing, and underlayment sized for the roof pitches common to this area, which keeps turnaround tight when a spring storm opens up a section of roof.
Grant Whitlock leads our team, and the standard he set was simple: no surprises on the invoice, no strangers without ID at the door, and no repair left unwritten. If a Mercer repair fails within 365 days, we return and make it right. That guarantee is written. It’s included. It’s not a negotiation.

Styles & brands we work with
Roof Maintenance in Glenn Heights
Roof maintenance in Glenn Heights means getting ahead of the two things that quietly shorten a roof’s life here: pooled debris at the decking seams and wind-driven rain that works under aging shingles near I-35E. The spring storm season in southern Dallas County and far northern Ellis County pounds east-facing slopes with heavy hail and straight-line wind, and the older 1970s-80s homes with original 3-tab shingles don’t shed water the way they did 20 years ago. A maintenance visit runs $250 – $500 and catches loose flashings, cracked sealant at pipe boots, and shingle tabs that have lost their seal. Small fixes now are far cheaper than a full replacement after the next supercell.
Fall And Spring Checks
Glenn Heights sees its heaviest hail from March through May, with a secondary wind season in late fall. We recommend a fall check before the winter freeze-thaw cycles set in, and a spring check right after the first severe storm line passes. The spring check is the one that matters most on the east side of town, where open exposure turns quarter-sized hail into a full roof replacement trigger.
What We Inspect
We walk every slope, check valleys for granule loss, lift shingle tabs to test seal strength, and pull the old leaves out of gutter ends that back water up against the fascia. On Glenn Heights homes built in the 1980s, we pay extra attention to the drip edge: many original installs nailed it directly to the fascia with no ice and water shield behind it, which is exactly where rotted decking starts after 30 years of wind-driven rain.
Roof Coating in Glenn Heights
Roof coating in Glenn Heights works on low-slope sections, porch roofs, and flat garage roofs that pitch and decking systems don’t cover as well. For a flat or metal roof, a properly applied elastomeric or silicone coating seals micro-fractures and reflects heat, which matters when July pushes attic temperatures past 140 degrees. Coating a low-slope section on a Glenn Heights home runs $1,200 – $3,500 depending on square footage and the condition of the existing surface. The coating bonds best on a clean, dry substrate, which is why we schedule coating work for dry stretches in late spring or early fall, when humidity in this part of Texas is low enough for proper cure time.
When Coating Makes Sense
If your flat roof is 10 – 15 years old but still structurally sound, a coating can add seven to ten years before a full tear-off. This is a good option for carports, overhangs, and the low-slope additions common on Glenn Heights homes built in the 1990s and 2000s. We’ll tell you honestly if the decking underneath is too far gone: coating over rotten plywood just makes the replacement bill bigger later.
Why We Seal Penetrations Separately
Before coating, every pipe boot, vent cap, and A/C penetration gets new sealant and a fabric-reinforced patch. Coating over old sealant is the number one reason flat roofs leak within a year in Glenn Heights. We’d rather spend an extra hour on penetrations than have you call us back after a heavy June thunderstorm.

AfterCommon Roofing Company Problems We See in Glenn Heights Homes
- Hail-stripped slopes on the east side near I-35E. Open exposure to the prevailing storm path means the east-facing roof plane takes the direct impact. We often find the original 3-tab shingles torn back to the nail line, with granules knocked off the shingles on the adjoining slope.
- Rotted decking under 1970s-80s drip edge. Builders here often nailed drip edge straight to the fascia with no ice and water shield between, so wind-driven rain wandered into the decking for decades. The shingles look okay from the ground, but underneath, the plywood has turned to mulch.
- Storm damage from falling limbs on tree-lined lots. Older subdivisions like Red Oak Creek and the established blocks off Bear Creek Road have mature oaks and pecans hanging over the roofline. A fallen branch doesn’t just tear shingles; it sometimes cracks the decking seam and opens a path for water to find the attic on the next rain.
- Failed valley flashing on original 1980s installs. The valleys on homes built in the 80s were often done with thin 26-gauge metal that has now rusted through. Water follows the valley seam down into the soffit and fascia, which is why we replace valleys, don’t caulk them, on any Glenn Heights roof over 20 years old.
Pricing for Roofing Company in Glenn Heights, TX
Here’s what a Glenn Heights homeowner should expect to pay. A focused repair, like re-flashing a pipe penetration or sealing a small leak, starts around $450. A valley replacement with new flashing and underlayment runs $800 – $1,400. Full replacement on a 1,800 – 2,400 sq ft home lands between $8,500 and $14,500, with the final number driven by pitch, decking condition, shingle grade, and how many roof penetrations need re-flashing. A roof coating on a low-slope section comes in at $1,200 – $3,500.
What moves the price more than anything on an older Glenn Heights home is the decking. Homes built in the 1970s and 80s with original shingles often have rotted sections that only show up after tear-off. Any roofer who quotes a replacement without pricing the decking allowance in writing is setting you up for a surprise change order. We write the decking allowance into the contract before we start, so when we open up the roof and find rot, the replacement cost per sheet is already agreed in writing. Call (432) 302-5605 for a free estimate, and we’ll give you a real number, not a teaser rate.

FAQs About Roofing Company in Glenn Heights
Because the original 3-tab shingles on those homes are already 25 – 40 years old, which means the seal strip has failed and the granules are worn down to the mat. When a hailstone hits an already-compromised shingle, the damage isn’t isolated; it’s the final straw across the whole slope. Patching a roof that age in Glenn Heights is a temporary fix that leaves you re-paying for a replacement within two years. If you’re unsure whether your roof is at that tipping point, call (432) 302-5605 for a no-pressure inspection and a written opinion on what’s actually repairable.
In southern Dallas County, a city roofing permit on a property where decking is opened often requires ice and water shield along the eaves and in valleys, and it can trigger a ridge vent upgrade if the current attic ventilation doesn’t meet the minimum ratio. That’s not a money grab; it’s code. Builders in the 1970s and 80s didn’t install ice and water shield to today’s standard, and older ridge vents are often undersized for a modern architectural shingle layer. We fold those upgrades into the written price before the first shingle comes off, so the permit inspection passes and you’re not hit with a surprise line item at the end.
East-side homes near I-35E take direct hail and wind from the prevailing storm path, so the east-facing slope gets brutalized first and most completely. Tree-lined lots in the older subdivisions like Red Oak Creek see fewer full-slope hail failures, but more blunt-force damage from falling limbs that crack decking and tear shingles in isolated spots. The inspection sequence changes based on where you live: east side, we inspect the whole east plane for hail bruising and granule loss; tree-lined lots, we check the valleys and drip edge first, then look for limb strikes. Both call patterns are common in Glenn Heights, and both drive different repair scopes.
Yes. Architectural shingles are thicker, have a stronger seal strip, and are rated for higher wind speeds than the 3-tab shingles they replace. On a Glenn Heights home near I-35E, a GAF architectural shingle rated to 130 mph is the difference between a roof that survives a spring supercell and one that gets stripped back to bare decking. The tradeoff is weight and cost: architectural shingles run $200 – $400 more per square than 3-tab. For the specific storm exposure on the east side of Glenn Heights, that’s money well spent.
We write the decking allowance and flashing replacement into the contract before we start, so when our crew opens up the roof and finds rotted plywood under the old drip edge, the per-sheet cost is already in writing. If the rot extends further than the allowance covers, we stop work, show you photos, and get written approval before we go one step further. No unapproved change orders. No surprise invoice. Just a written price for exactly what we found, and your sign-off before we touch it. Call (432) 302-5605 to schedule your free estimate in Glenn Heights.
