Owens Corning Roof Replacement in McKinney – Vista of Eldorado
A windstorm damaged the roof on this 13-year-old home in McKinney’s Vista of Eldorado neighborhood, tearing loose shingles that the homeowner’s handyman had to temporarily tarp over. With the roof already nearing the end of its typical service life, the homeowner’s insurance carrier approved a full replacement rather than a patch repair. Our team handled the project from initial inspection through final walkthrough, replacing the roofing system (down to the decking in some areas) with new architectural shingles, upgraded underlayment, and additional attic ventilation built for North Texas storms and heat.

The Challenge: A 13-Year-Old Roof Meets a Windstorm
A windstorm passed through Vista of Eldorado and damaged shingles across this home’s roof, which was already 13 years old and nearing the end of its expected service life. The homeowner’s handyman put temporary tarps over the worst-hit areas while the homeowner worked with their insurance company to get a replacement approved.
With a roof already at that age, wind damage on top of normal wear made a full replacement the more sensible path forward rather than patching isolated areas. The homeowner’s insurance carrier approved the project, and the goal was a roofing system built to hold up against the same kind of wind events that had already gotten the better of the old shingles.
The Discovery: Steep Pitches and Undersized Ventilation
Once tear-off began, the crew found that the home’s roof planes ranged from 7/12 to 9/12 pitch. Slopes that steep increase wind uplift on aging shingles and require more careful footing and handling during both removal and installation.
The original ventilation setup relied on a mix of turbine and box vents that wasn’t pulling enough hot air out of the attic for a home this size. The team also found that flashing around the valleys and roof edges had degraded enough that it needed full replacement rather than reuse.
The Solution: A Full System Replacement, From Decking to Ridge
The team removed the old roofing system and installed TRI® Charcoal Bronze Style A aluminum drip edge along the perimeter to direct water into the gutters. Over the bare decking, we applied Owens Corning® ProArmor® synthetic underlayment, which resists tearing better than traditional felt paper, and lined the valleys with Owens Corning® WeatherLock® Mat self-sealing waterproofing barrier to keep water from migrating sideways under the shingles.
The main roofing layer is Owens Corning® TruDefinition® Oakridge® architectural shingles in Estate Gray, secured with coil roofing nails. To address the ventilation issue found during discovery, we replaced the mixed turbine/box vent setup with five Air Vent 12-inch externally braced aluminum turbine vents. Plumbing stacks were resealed with new galvanized flashing and lead pipe jacks, coated in Rust-Oleum® protective spray paint to match the shingle color.
The Results: A Wind-Resistant Roof With Better Airflow
The home now has a dimensional architectural shingle profile that gives it a more modern look than the flat 3-tab shingles it replaced. The upgraded turbine ventilation gives the attic continuous airflow, which should help ease the load on the home’s air conditioning during North Texas summers.
With new underlayment, valley barrier, and flashing throughout, the roof is set up to shed wind-driven rain without the vulnerabilities that led to this replacement in the first place.
The Phillips Way
How we handled every step of this project — from first inspection to final sign-off.
Step 1
Inspect & Document
Our team assessed wind damage across the roof and documented the steep 7/12 to 9/12 pitch slopes that would require extra care during tear-off.
Step 2
Advocate & Confirm
We worked with the homeowner’s insurance claim to make sure the scope of work matched what the roof actually needed, including the ventilation upgrade.
Step 3
Prepare & Protect
Protective tarps were set up around the property’s landscaping and exterior features to catch debris during the tear-off.
Step 4
Install & Restore
Crews installed Owens Corning architectural shingles, ProArmor underlayment, WeatherLock valley barrier, and five aluminum turbine vents across the steep-pitch roof.
Step 5
Clean Up
The crew hauled off old shingles, underlayment, and packaging then swept the property with magnetic sweepers to pick up loose roofing nails from the lawn and landscaping.
Step 6
Walkthrough & Sign-Off
The completed roof was reviewed with the project manager and homeowner to confirm every item in the scope of work was finished.

Why Proper Preparation Matters
On a roof with pitches as steep as 7/12 to 9/12, safe footing and full debris removal matter just as much as the materials going down. The crew set up tarps around the landscaping and exterior features to catch old shingles and nails during tear-off, then cleared the decking down to bare wood so the new underlayment could lay flat without gaps or trapped debris underneath.
Materials Selected for Long-Term Performance
Owens Corning® TruDefinition® Oakridge® shingles were selected for their dimensional, heavier-weight construction, which holds up better against wind uplift than standard 3-tab shingles — relevant given this roof was replaced because of wind damage. ProArmor® synthetic underlayment was used in place of traditional felt paper because it resists tearing and holds up better under temperature swings. WeatherLock® Mat was installed in the valleys, where the largest volume of water runs during a storm, to seal around every nail penetration and keep water out of the decking below.
The Phillips Approach
This project involved working through the homeowner’s insurance claim to make sure the approved scope actually matched what the roof needed — including the ventilation upgrade, which wasn’t part of the original 3-tab shingle scope. Rather than installing standard shingles over the old underlayment, the team replaced the full system: decking-level moisture barrier, valley lining, drip edge, and ventilation, along with the primary shingle layer. The steep-pitch sections were handled with the same care as the rest of the roof, down to matching the pipe jack paint color to the new shingles.
