This case study details the complete roof replacement performed by Presidio Roofing Company for a residential property in Oakmont Estates in Corinth, Texas. The project involved removing storm-damaged architectural shingles and installing GAF Timberline HDZ Barkwood Architectural Shingles to improve energy efficiency and wind resistance. The project was completed in April 2025 with a total coverage of 5,400 sq ft.
This roof replacement had unique challenges. First off, we were under a time crunch due to this roof being replaced coincided with the sale of the home. Couple that with a poor weather forecast and we were left with only a one day window to complete the entire 5,400 square foot job, including the gutters. The home had multiple leaking skylights that had to be addressed and the backside of the home had a metal extension tied into the shingles that had to be salvaged. Lastly, the roof had a pretty severe pitch of about 12/12 (or around 45 degrees).

Challenge 1: Severe Time Crunch Coupled With Inclement Weather
This roof needed to be replaced asap as part of the closing of the sales of the home to new buyers. Luckily USAA insurance agreed there was hail damage and paid for the roof but it was rainy season in North Texas and they needed the roof done within a week roughly. The forecast had 1 sunny day in that time period.
The Solution: Proper Preparation & Mobilization
We quickly moved to get materials ordered and crew ready. We had 1 sunny day to get this roof done and brought out an oversized crew of 14 people to make sure we would finish it in 1 day. This is why having a company like Presidio that has the ability to mobilize crew and materials, and install a $45k roof in 1 day on minimal notice is a huge advantage for homeowners needing quick service. Most companies do not have the ability to control so many moving parts so fast.
Our crew of 14 guys started the job at 6am and were done by sun down and like expected it rained the next day.
Challenge 2: Fix Multiple Leaky Skylights
The skylights on this job were weak points. They had previous leaks so we needed to treat them with caution.
The Solution: Practical Know-How and Execution
We tore the roof to the decking as should occur on all roof replacements. This let us get to the bottom of any issue and build back up. With the flashings we replaced the step flashing as well as wrapping them in ice and water shield. This creates a seamless barrier for any water to flow along the top and the sides of the skylight curbs.
Challenge 3: Salvage & Incorporate the Metal Roof Extension in the Back
The back side of the home had a metal roof extension that tied into the shingles but was not be replaced as part of this work scope. That meant we need to protect it from damage as well as make sure it was properly flashed in with the new shingles.
The Solution: Patience, Attention to Detail and Diligence
We carefully laid out osb boards across the entire metal roof facet so that there was a sturdy surface on top of it in case shingles or other debris fell down onto it. Doing this with wood is important because just tarping it could still lead to scratching of the metal surface through the tarp.
For the transition to the shingles we followed all GAF specs for metal roof tie-ins which are also called transition flashings. We use rolled metal as well GAF stormguard leak barrier to create a self adhered and seamless flashing so water can not flow back up under the asphalt shingles from the metal roof.
The Result:
A difficult but outstanding roof installed in one day and covered by an awesome warranty. Zero skylight leaks and zero damage to the tied-in metal extension in the back. The home was sold without any delays.
How to Maintain Your New GAF Timberline HDZ Class 3 Shingle Roof
After any severe weather event, perform a ground-level inspection. Look for signs like dings in your gutters, tears in window screens, or shingles lying in the yard. Do not climb the roof yourself; call a professional if you suspect damage.
Ensure that leaves and branches are cleared from roof valleys and gutters. Accumulated debris can trap moisture and lead to algae growth or water backing up under the shingles.
Check your downspout splash blocks. If you see excessive accumulation of granules (the “sand” from the shingles), it may indicate that the roof is aging or has sustained new hail damage.
