Complete GAF Timberline HDZ Shingle Roof Replacement | Full Flashing and Balanced Attic Ventilation Upgrade
This Round Rock shingle roofing project replaced an aging composition roof in the Greenlawn neighborhood. We installed GAF Timberline HDZ architectural shingles over FeltBuster synthetic underlayment and StormGuard ice and water shield. These GAF materials hold up well against Central Texas hail and 100-degree summers. The finished roof gives the homeowner strong protection and a clean, modern look.

The homeowner reached out to Austin Pro on November 27, 2023, through a family and friend referral handled by our office staff. The first conversation focused on storm damage to an aging composition roof in Greenlawn. We logged it the same day as both a prospect and a qualified lead.
Our team inspected the existing roof and found worn comp shingles along with aged flashing at the pipe boots and electrical mast. We documented the condition for the insurance claim. The findings pointed clearly to a full tear-off rather than a patch.
The project moved to approved status on November 30, 2023, just three days after first contact. We built the estimate around a complete GAF Timberline HDZ system and confirmed materials through the distributor. This being insurance work, the scope was set to match claim requirements.
Crews completed the tear-off and rebuild on January 2, 2024. They laid FeltBuster synthetic underlayment across 10 squares, added StormGuard ice and water shield in the vulnerable zones, and set 120 feet of ProStart starter strip. New vents, drip edge, and flashing finished the system.
The roof was completed January 2, 2024, with all penetrations sealed and touched up. Installing the full GAF system as one package qualified the roof for stronger warranty coverage.
We replaced a worn composition roof on a home in the Greenlawn neighborhood of Round Rock, TX, with a full GAF Timberline HDZ shingle system. The old roof came off, and a tighter, storm-ready roof went on in its place.
The old composition shingles had reached the end of their life. Years of Central Texas hail and relentless summer sun had worn them thin. This was insurance work, so the priority was a full, code-correct rebuild.
Once the old shingles came off, we got a clear look at the deck and all the roof penetrations. Round Rock roofs take a beating from wind-driven rain and cedar pollen that packs into every seam and valley. We found the usual weak points around the pipe boots and the electrical mast, where old flashing had aged past its useful life. Rather than patch those spots, we replaced every flashing piece so water has no path back into the home. That kind of detail is what most homeowners never see, but it is exactly where roofs tend to fail first.
We built this roof as a complete GAF system, not just a shingle swap. Timberline HDZ shingles handle Texas heat and hail better than basic three-tab options, and the matched components carry a stronger warranty when installed together.
The synthetic underlayment matters more than folks expect. Old felt paper soaks up moisture and tears in high wind. Synthetic stays flat and dry, which keeps your deck protected even if a shingle lifts in a storm.
Good airflow keeps an attic cooler and helps shingles last through 100-degree summers. We set up a balanced vent system as part of the rebuild.
The crew completed the full tear-off and rebuild on January 2, 2024. Fasteners were spec-driven throughout, with 7,200 roofing coil nails and 2,000 plastic cap nails securing the underlayment and shingles. Every seam and penetration got sealed with Geocel 2300 TriPolymer sealant. Exposed metal touch-ups were finished with Rustoleum protective enamel for a clean look.
The homeowner ended up with a tight, well-vented roof designed for the long haul in Central Texas. Every flashing point was renewed, so limestone-soil settling and heavy downpours have no easy way in. The GAF system also gives this Round Rock home a fresh, uniform finish from the street.
The on-site work wrapped in a focused push, finishing January 2, 2024. The project was approved on November 30, 2023, so scheduling and prep took just over a month.
These architectural shingles resist wind and impact far better than three-tab shingles. That matters in a region where spring hail and summer heat both test a roof hard.
Yes. This was logged as an insurance project, and the total landed in the $10k–$15k range. We worked through the claim and material orders with the distributor to keep the scope accurate.
Installing matched GAF components as one system qualifies the roof for stronger manufacturer coverage than mixed brands allow. That is a key reason we build every layer with the same vendor.
