Shingle Roofing in Greenlawn, Round Rock, TX

Why did this Greenlawn home need a new roof?

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.

• Work type logged as an insurance claim
• Old comp shingles removed with full haul-off and disposal
• Value fell in the $10k–$15k range
• Lead came through a family and friend referral

What did the crew find during tear-off?

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.

What materials did we use, and why?

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.

• GAF FeltBuster Synthetic Underlayment across 10 squares for a dry, tear-resistant base
• GAF StormGuard Ice & Water Shield at 2 squares for the most leak-prone areas
• GAF ProStart Starter Shingle Strip running 120 feet along the eaves
• GAF Z-Ridge capping 33 feet of ridge line
• ACM Galvanized Steel Drip Edge, 2x2, protecting the roof edges

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.

How did we handle attic ventilation?

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.

• Air Vent RVG-55 galvanized steel slant-back box vent
• Air Vent TOB-12S 12-inch turbine
• New galvanized steel base pipe flashing sized 1 1/2 to 3 inches
• GAF Aluminum Versa Cap #3050 for the mast penetration

How did the installation go?

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.

What were the results?

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.
