Owens Corning Roof Inspection in Fort Worth: What to Know First
An independent Owens Corning roof inspection in Fort Worth typically takes 45 to 90 minutes and costs between $150 and $400 depending on roof size, pitch, and access. We walk the roof, check the decking and flashing by hand, and give you a written report with photos and a straight answer about what needs attention now and what can wait. No sales pitch attached to the inspection, and the price goes on paper before we show up.
This page is for homeowners in Fort Worth who have Owens Corning shingles, underlayment, or ventilation products and want someone who knows how those specific materials age in North Texas weather. If you have curling shingles, granule loss in the gutters, or a leak you can’t trace, call (682) 900-7902 and we’ll get you on the schedule.
How Owens Corning Products Fail – and How We Fix Them
- Duration Series granule loss after hail seasons. Owens Corning Duration shingles use SureNail fabric, but the granule layer takes a beating in Fort Worth hail country. We regularly see Duration shingles from 2016 to 2019 that shed granules faster than expected after two or three storm seasons. The real cause is usually impact damage that fractured the granule bond, not a manufacturing defect. Our fix: we document the loss pattern across the roof face, check for bruising under the mat, and recommend either spot replacement or a full reroof depending on how far the loss has spread.
- Oakridge series edge lifting at the rake. Oakridge shingles are a common sight on Fort Worth homes built before 2010. The failure mode we see most is edge lifting at the rake and eave lines, where sealant strips break down under sustained UV exposure and wind. The shingle itself is fine, but the seal strip has given up. We reseal or replace the affected shingles and check the drip edge behind them, because if the drip edge is rusted or loose, the lifting will come back.
- Decking rot under Owens Corning underlayment failures. When Owens Corning Deck Defense or older felt underlayment fails at a seam or valley, water sits on the decking and rots it before you ever see a ceiling stain. In Fort Worth, the freeze-thaw cycle in January and February makes small underlayment tears widen. We pull shingles at suspect valleys and penetrations during inspection, not just around the obvious leak. If the decking is soft, we show you a photo and tell you the square footage that needs replacing.
- VentSure ridge vent clogging in North Texas pollen season. Owens Corning VentSure ridge vents are well built, but Fort Worth live oaks dump pollen and leaf debris every spring, and it collects inside the vent baffles. A clogged ridge vent shortens the life of the entire roof system because attic heat and moisture stop moving. We check airflow at the ridge during every inspection, and if it’s clogged, we clear it or recommend a vent replacement if the baffles are crushed from past hail.
- Synthetic underlayment seam tape separation on steep Fort Worth roofs. On Owens Corning RhinoRoof or ProArmor synthetic underlayment, we see seam tape release on roofs steeper than 8/12, especially on south-facing slopes that get the full Texas sun. The tape adhesive breaks down and the seam opens, letting wind-driven rain reach the decking. Our inspection specifically checks seam integrity on steep southern exposures because that’s where the failure hides, often with no interior leak until the decking is already compromised.
Styles & brands we work with






Our Owens Corning Roof Inspection Process
- 1
Call and schedule. A live person answers at (682) 900-7902, takes your address and roof details, and books a two-hour arrival window. You get a written price for the inspection before we come out.
- 2
Exterior walk and roof walk. Travis Oakley or one of our background-checked, uniformed technicians walks the roof itself, checking shingle condition, granule retention, seal strips, flashing at chimneys and pipes, valley metal, drip edge, and ridge vent airflow. We do not inspect from the ground or from a ladder at the eave only.
- 3
Attic check. We go into the attic and look at the underside of the decking for water stains, mold, or soft spots. This is where Owens Corning underlayment failures show up before the shingles do.
- 4
Parts decision. If we find damage, we tell you whether the fix needs Owens Corning OEM materials to preserve a manufacturer warranty, or whether a quality matching aftermarket component will do the job at a lower cost. We explain the trade-off in plain English so you decide with real information.
- 5
Written report. You get a report with photos, measurements, and a line-item list of what we found, what it needs, and what it costs. The price goes on paper before any repair work starts, and it does not move at the door.
- 6
Guarantee. Every repair or replacement we do is backed by the 365-Day Done Right Promise in writing. If it fails within a year, we come back and make it right at no charge.

AfterWhat Owens Corning Roof Inspection Costs in Fort Worth
Most Owens Corning roof inspections in Fort Worth land between $150 and $400. A straightforward single-story ranch with a 15-minute walk and standard attic access runs $150 to $225. A two-story home with a steep pitch, multiple valleys, and a tight attic runs $275 to $400. If you need a documented inspection report for an insurance claim or a real estate closing, that’s on the higher end because it takes longer to photograph and document every slope.
What moves the price: roof size, pitch, number of stories, attic accessibility, and whether you need the full written report with photos. We do not charge a trip fee, and the inspection price is on paper before we arrive. If you hire us for a repair found during the inspection, we credit the inspection fee toward the repair. Call (682) 900-7902 for an exact quote, and the estimate is free.
Why Fort Worth Homeowners Call Brennan Roofing Co Fort Worth for Owens Corning Work
We’re an independent Owens Corning service provider in Fort Worth, not a factory-authorized dealer, which means we answer to you, not to a corporate program. We work on Owens Corning roofs because they’re common here and we know their failure patterns, but we also install and inspect GAF, CertainTeed, IKO, Atlas, Tamko, and Boral materials, so our recommendation is never forced toward one brand. Every technician who steps onto your roof is background-checked and in uniform, and you’ll know exactly who’s up there.
The Garrison Standard is the rule we operate under: written price before any work starts, a live person on the phone around the clock, and a one-year written guarantee on every job. Travis Oakley walks roofs himself, checks decking and flashing by hand, and gives straight answers. His rule is simple: “Tell me what the roof is doing – we’ll figure out what it needs.” Call (682) 900-7902 and you’ll get a live person, not a voicemail queue.
FAQs
No. Having an independent contractor inspect your Owens Corning roof does not void the manufacturer warranty. The warranty covers material defects, and an inspection doesn’t alter that. What can void a warranty is improper repair work or installation using non-compatible materials, which is why we’re careful to flag OEM versus aftermarket part decisions and explain them before touching anything.
We can typically schedule an Owens Corning roof inspection in Fort Worth within 3 to 5 business days, depending on weather and season. If you have an active leak or storm damage, call (682) 900-7902 and we’ll work you in sooner. Hail season in March and April fills the schedule fast, so call early if you suspect impact damage.
Repair makes sense when the damage is isolated: a handful of lifted shingles, one damaged valley, or flashing that has separated but hasn’t rotted the decking. Replacement is the honest answer when granule loss covers most of the roof face, the seal strips have failed on multiple slopes, or the decking under the underlayment is softening in more than one spot. We’ll show you photos of what we found and give you both numbers, repair cost and replacement cost, so you can decide with a written price in hand.
For most common Owens Corning lines in Fort Worth, Duration and Oakridge especially, matching shingle colors are available through our local supply houses within a day or two. Some older or discontinued color blends take longer, and if we can’t match the shingle exactly, we’ll tell you before we start and offer a close-match option or a different approach. We don’t start work until you’ve approved the plan and seen the written price.
It covers the work we do, in writing, for one full year. If a repair we made fails within that period, we return and fix it at no charge. No fine print, no trip fee, no argument. That’s the Garrison Standard on every job, Owens Corning roof or any other.
