Scope of Work
What We Did
Complete GAF Timberline HDZ SG Roof Replacement · 5-Inch Gutter System with Oversized 3x4 Downspouts
Shingle Roofing
This Round Rock shingle roofing job started with a full tear-off and haul-away of the aging roof. We installed GAF Timberline HDZ SG asphalt shingles, a proven pick for Central Texas hail and 100-degree summers. The steep 8/12 and 10/12 pitch meant a careful, multi-day install with proper safety and detail. We finished with GAF Tiger Paw underlayment, StormGuard ice and water shield, ProStart starter strip, and Cobra ridge venting to keep the attic cooler and the roof watertight.

We wrapped this Round Rock project with new 5-inch seamless aluminum gutters and 3x4 downspouts. Seamless gutters are formed on site, so there are no middle seams to crack or leak. The larger 3x4 downspouts handle the fast runoff from a steep roof during sudden Texas downpours. The whole gutter install took just one day once the roofing was complete, leaving the home ready for storm season.

How It Went
The Journey
From the first phone call to the final walkthrough — what actually happened on this project.
First contact
October 4, 2023The homeowner reached Austin Pro on October 4, 2023 through a family referral passed along by our office staff. The first conversation focused on storm damage to the aging comp roof and the insurance claim process.
Evaluation
October 17, 2023We inspected the roof and found worn comp shingles across steep 8/12 sections, plus tired flashing at the penetrations. The gutters were also due for replacement. Findings moved the job to the prospect stage on October 17, 2023.
Planning & approval
October 18, 2023The project was approved on October 18, 2023, just one day after the prospect stage. We built the scope as a full GAF Timberline HDZ SG system with a matching 5-inch gutter package to fit the insurance claim.
Installation
The crew tore off the old shingles and installed the new GAF system over multiple days, taking extra care on the 8/12 and 10/12 steep sections. Tiger Paw underlayment, StormGuard, ridge venting, and new flashing all went in before the gutters followed in a single day.
Completion
October 30, 2023Both the roof and gutters were completed on October 30, 2023, with a final cleanup and metal touch-up using Rust-Oleum enamel.

The Full Story
Inside This Project
Why did this Round Rock home need a new roof?
The existing comp shingles had reached the end of their service life. Years of hail, hard sun, and wind had worn the shingle mat thin. This was insurance work, so getting the full system right mattered for long-term coverage.
- Full tear-off of old comp shingles with haul off and disposal
- Steep-pitch sections at 8/12 on the roof and 10/12 on the gutter runs
- Lead came in October 4, 2023 through a family referral to our office staff
- Approved fast, just one day after the prospect stage
What did the crew find during the roof work?
Steep pitch was the story on this house. We logged a steep fee for the 8/12 roof and a separate charge for a 10/12 section, which changes how a crew moves and how long each square takes. Steep roofs slow everyone down for safety, so we planned this one over multiple days instead of rushing it. The pitch also means water sheds fast, which makes the underlayment and flashing details even more important. Skip those, and steep roofs leak at every penetration. We took the time to get the pipe flashing and ridge caps sealed right.
- GAF ProStart starter strip run along the eaves (120 feet)
- GAF Z-Ridge hip and ridge caps (33 feet)
- Galvanized steel base pipe flashing sized 1 1/2 to 3 inches
- Geocel 2300 tri-polymer sealant at penetrations
What materials went into the roof, and why?
We built the roof as a full GAF system, not just shingles on felt. Timberline HDZ SG shingles sit on Tiger Paw synthetic underlayment, with StormGuard ice and water shield at the vulnerable spots. The synthetic underlayment holds up to Central Texas heat far better than old-style felt, which can dry out and crack when attic temps climb past 100 degrees. We also added a mix of Cobra ridge venting and a slant-back box vent to move hot air out of the attic. Balanced airflow keeps the shingles cooler from below and helps them last their full life.
- GAF Tiger Paw underlayment (10 squares)
- GAF StormGuard ice and water shield (2 squares)
- GAF Cobra Rigid Vent 3 ridge exhaust (4 feet, 9-inch)
- Air Vent RVG-55 galvanized slant-back box vent
- ACM galvanized drip edge, 2x2 profile
- 1 1/4-inch coil nails and 1-inch plastic cap nails for underlayment
How did the gutter install go?
The gutters went in as a clean one-day job after the roof was finished. We ran 5-inch gutters with 3x4 downspouts, sized to handle the heavy, fast rain that hits Round Rock in storm season. Oversized downspouts also clog less when cedar pollen and leaf grit wash off the roof.
- New 5-inch gutters with 3x4 downspouts
- Installed as a single-day phase after roof completion
- Downspouts route water away from limestone-heavy soil near the foundation
- Aluminum Versa Cap #3050 flashing detail tied into the roof edge
What were the results?
The home now has a complete, sealed roof-and-gutter system ready for the next hail season. The GAF setup carries strong manufacturer coverage, and the gutters protect the fascia and foundation from runoff. Everything closed out cleanly in early 2024.
- Roof and gutters both completed October 30, 2023
- Invoiced December 14, 2023; file closed February 22, 2024
- Project value landed in the $15k–$20k range
- Rust-Oleum protective enamel used to touch up exposed metal
Straight Answers
Questions About This Project
Why are GAF Timberline HDZ shingles a good fit for Round Rock?
They handle heat, wind, and hail well, which matters in a region that sees all three. The HDZ line also installs with a wide nailing zone, so the crew can seat each shingle accurately even on a steep 8/12 pitch.
How long did the whole project take?
The roof ran over multiple days because of the steep pitch, and the gutters followed in one day. From approval on October 18 to completion on October 30, 2023, the field work wrapped in under two weeks.
Why use 3x4 downspouts instead of standard ones?
Bigger downspouts move more water per minute and resist clogging from cedar pollen and debris. During a hard Central Texas downpour, that extra capacity keeps water off the fascia and away from the foundation.
Was this covered by insurance?
Yes, this was an insurance claim job. We documented the storm damage and matched the full GAF system to the scope, so the homeowner got a complete roof rather than a patch.
