Owens Corning Roof Inspection in Dallas: What to Know First
We provide independent Owens Corning roof inspections across Dallas, and in most cases we can complete the inspection and put a written report in your hand within 24 to 48 hours. The inspection itself runs $195 to $395 depending on roof size, slope, and whether you need thermal imaging or a second-story inspection by ladder. This is a real price, on paper, before we ever set foot on the roof, and it doesn’t change once the work begins.
This page is for Dallas homeowners who own Owens Corning roofing and want a straight answer about its condition, its remaining life, and what it will cost to fix what’s wrong. If you’ve got a Owens Corning Duration or Oakridge roof, or you’re not sure which line you have, we’ll identify it and tell you exactly what leaks, what doesn’t, and what to do next. Call (903) 499-4441 to schedule an inspection. A live person answers, 24/7, no voicemail queue.
How Owens Corning Products Fail – and How We Fix Them
Owens Corning makes solid roofing, but every product line has its own failure pattern. Here’s what we find on Dallas roofs, what causes it, and how we correct it.
- Duration Series shingles losing granules at the leading edge. Old Duration shingles sometimes drop granules along the lower edge, especially on south-facing slopes in Dallas where the sun beats on the same spot all afternoon. The asphalt then oxidizes and hairline cracks form. The fix is not caulk, it’s replacement of the affected shingles with color-matched Owens Corning material or closest-approved equivalent, sealed with proper nail placement.
- Oakridge shingles cracking at the nail line. Oakridge is a lighter line, and when nailing was done too high, too hard, or too close to the edge, a line of cracks opens up right at the shingle’s fastener zone. We replace those shingles and adjust the nailing method on any new installation so the same stress doesn’t recur.
- Decking failure under Owens Corning vent caps. In Dallas we see a lot of nail-anchored vent caps working loose after 8 to 12 years of high wind and thermal movement. The shingle around the cap is fine but the decking underneath has softened from moisture that wicked in around the loosened fasteners. We pull the cap, dry the area, repair the decking, and re-set it with correct fastening and sealant.
- Flashing failures at roof-to-wall junctions over Owens Corning stripping. The shingle itself often isn’t the leak source; it’s the original galvanized flashing behind the step flashing that has corroded through in Dallas’s wet-dry seasonal cycling. We remove the affected shingles, replace the flashing, and reinstall the Owens Corning material so the wall junction sheds water correctly.
- Hail bruising on Owens Corning Duration Designer lines. Dallas hail bruising shows up as soft spots in the shingle mat that are invisible from the ground. The mat fractures under the granule layer even if the surface still looks intact. We check for bond failure at the sealant strip and examine the mat from underneath when possible, which is a check most roof inspections skip.
Each of these is a repair, not a reroof. We fix what’s broke and leave the rest alone, because replacing a whole Owens Corning roof over one failed flashing run is the exact move that keeps a homeowner poorer than they need to be.

Our Owens Corning Roof Inspection Process
This is the procedure we follow on every Owens Corning inspection in Dallas. No shortcuts, no drive-by look from the street.
- 1
We walk the property with you. We note what you’ve already seen: stains on the ceiling, granules in the gutter, a lifted shingle edge you spotted from the lawn. Your observations set the starting point.
- 2
We inspect every slope, valley, ridge, and penetration. Ladder work, not binoculars. We get on the roof and put hands on the shingles.
- 3
We pull samples when needed. If a shingle feels soft or the mat is suspect, we take a small sample from an inconspicuous location, check the mat and sealant strip condition, and show it to you before we leave.
- 4
We test the flashing and sealants. Step flashing, counterflashing, pipe boots, exhaust vents, box vents, chimney flashing. We prod, peel back, and photograph each joint.
- 5
We inspect the attic and the decking. Moisture readings, fastener inspection from below, decking condition, ventilation balance. Owens Corning products perform best when the attic moves air properly.
- 6
You get a written report. Then, if we find anything, you get a written price. Repair recommendations, life expectancy, warranty implications. The price goes on paper before any work starts and it does not move at the door.
Every repair we do on an Owens Corning roof is covered by the 365-Day Done Right Promise: if it fails within one full year, we come back and make it right at no charge. In writing.
What Owens Corning Roof Inspection Costs in Dallas
The straight numbers, because you shouldn’t have to call just to get a ballpark:
- Visual roof inspection (single story, standard slope): $195 to $250
- Visual inspection with full attic access and moisture readings: $275 to $350
- Two-story inspection with thermal imaging: $350 to $395
- Inspection after hail or storm event (with documentation for insurance): $250 to $395, depending on scope and whether you need photos formatted for an adjuster
What moves the price: roof complexity, number of stories, whether we need to pull back shingles to examine decking, and whether you want a second technician to shoot thermal imagery of the attic. Square footage matters less than you’d think; it’s the pitch, access, and damage level that determine labor.
We never charge for the estimate on any repair that comes out of the inspection. Call (903) 499-4441 and we’ll get you scheduled. The inspection price is fixed before we arrive.

AfterWhy Dallas Homeowners Call Brennan Roofing Co Dallas for Owens Corning Work
Because when Travis Oakley sends a crew to your house, the price is already on paper and the two guys who show up are background-checked, in uniform, and they know exactly what they’re supposed to do. That’s The Garrison Standard. It’s the same on a $400 flashing repair as it is on a $40,000 full replacement.
We’re not an Owens Corning authorized dealer or affiliate. We’re an independent Owens Corning service provider based here in Dallas, which means we call the fix straight: if your Owens Corning roof has ten more years left in it, that’s what we tell you. If it doesn’t, you’ll hear that too, with the numbers to back it up. We also stock and install GAF and CertainTeed, so if a full replacement ever makes sense, we’ll price your options without pushing you toward one brand or another.
A roof either keeps water out or it doesn’t – everything else is just conversation. We live by that, and we put it in writing.
FAQs
No. The Owens Corning material warranty remains with the shingles regardless of who inspects or repairs them. What we are careful about is using repair methods and materials that don’t compromise the manufacturer’s warranty language, which is why we use Owens Corning or closest-approved materials on all repairs.
In almost all cases, yes. Owens Corning produces the Duration, Oakridge, and Duration Designer lines in large production runs and most colors are stocked or special-ordered within two to four weeks. We’ll match the color and the shingle series, not just the color, since a mismatched series is obvious even from the street. Call (903) 499-4441 if you want us to bring a color sample to your next inspection.
We give you a written report that states the remaining life in years, the cost to repair what’s currently wrong, and the cost per year to replace versus keep. If the repair cost exceeds what the roof is worth in remaining life, we tell you to replace. The replacement quote comes with the same written-price guarantee as a repair.
We can usually get out within 24 to 48 hours of your call, and we prioritize storm-related inspections when homeowners have water actively entering the house. The inspection includes photos formatted for your insurance claim, including mat bruising documentation that many adjusters miss. Call (903) 499-4441 and a live person will get you scheduled.
On shingle replacements we use Owens Corning material whenever it’s available, color-matched and series-matched. On underlayment, flashing, and ventilation we use manufacturers that Owens Corning’s own installation guides accept as compatible. We never substitute a cheap underlayment to shave a few dollars off a repair because that underlayment is what fails first and we’d be coming back to fix it under the guarantee.
