Introduction
This case study covers the complete roof replacement Presidio Roofing performed for a residential property in Oakmont Estates, Corinth, Texas. The work involved removing storm-damaged architectural shingles and installing GAF Timberline HDZ Barkwood Architectural Shingles to improve energy efficiency and wind resistance. The project wrapped in April 2025, covering 5,400 sq ft.
This job came with a full set of complications. The roof had to be done as part of a home sale closing, and the timeline wasn’t flexible. North Texas was deep into rainy season, and the forecast gave us one workable day to finish the entire 5,400 sq ft job, including the gutters. The home also had multiple leaking skylights and a metal extension on the back that tied into the shingles – both required careful handling. The roof pitch was a steep 12/12, about 45 degrees
Challenge 1: Severe Time Crunch Coupled With Inclement Weather
The roof needed to be replaced right away – the home sale was closing and the new buyers were waiting. USAA confirmed hail damage and covered the roof, but it was rainy season in North Texas. They needed the job done within about a week, and the forecast gave us exactly one sunny day to work with.
The Solution: Proper Preparation & Mobilization
We moved fast – materials ordered, crew staged. With one workable day, we brought out 14 people to make sure the job got finished start to finish. Not many companies can mobilize a crew, coordinate materials, and install a $45k roof in a single day on short notice. That capability matters when a homeowner’s closing date is on the line.
The crew was on-site at 6am and done by sundown. It rained the next day, exactly as forecast.
Challenge 2: Fix Multiple Leaky Skylights
The skylights were a known weak point. Previous leaks meant we couldn’t treat the flashing as a routine job.
The Solution: Practical Know-How and Execution
We stripped the roof to the decking – the right call on any full replacement. That gave us a clean foundation to assess and build back up from. At the skylights, we replaced all step flashing and wrapped the curbs in ice and water shield, creating a continuous barrier along the top and sides to stop water intrusion at the source.
Challenge 3: Salvage & Incorporate the Metal Roof Extension in the Back
The back of the home had a metal roof extension that tied into the shingles but fell outside this project’s scope. We needed to protect it from damage during installation and make sure the transition to the new shingles was correctly flashed.
The Solution: Patience, Attention to Detail and Diligence
We laid OSB boards across the entire metal roof section to create a solid working surface and protect the metal from debris. Tarping alone isn’t enough – material and foot traffic can still scratch through.
For the transition, we followed GAF specs for metal-to-shingle tie-ins, using rolled metal and GAF StormGuard Leak Barrier to build a fully adhered, continuous flashing. Water can’t travel back up under the shingles from the metal surface.
The Result
Fourteen crew members, one day, 6am to sundown. The roof was finished before the rain returned. USAA approved the hail damage claim and covered the full project, which came in at $45,000-$49,000 and carries a GAF Golden Pledge Warranty with 25-year workmanship coverage. Zero skylight leaks post-installation. No damage to the metal roof extension.
The homeowner told us that finishing the entire roof in one day was the only reason the closing stayed on schedule. The home sold on time, with no roofing-related delays to the transaction. Read more from clients who’ve been through the same process.
How to Maintain Your New GAF Timberline HDZ Class 3 Shingle Roof
While your new roof is built to last, regular maintenance ensures it remains eligible for warranty claims and performs optimally.
After any severe weather, do a ground-level inspection. Dings in gutters, torn window screens, shingles in the yard – these are all signs worth a call. Stay off the roof and bring in a professional if anything looks off.
Keep roof valleys and gutters clear of leaves and branches. Trapped debris holds moisture, which leads to algae growth and water working back under the shingles over time.
Check your downspout splash blocks regularly. Excessive granule buildup – the gritty “sand” from the shingles – can signal aging or new hail damage. Either way, it’s worth a closer look.
