GAF Timberline HDZ Architectural Shingle Roof with Golden Pledge Warranty | R-Panel Metal Roofing Over Screened-In Porch









This Austin home needed a full shingle roof replacement after storm damage in Colony North. We removed the old comp shingles and installed GAF Timberline HDZ SG architectural shingles. The system uses FeltBuster synthetic underlayment, StormGuard ice and water shield, and Cobra ridge venting. HDZ shingles resist Central Texas hail and hold up under 100-degree summer heat.

We also replaced the screened porch roof with durable R-panel metal roofing on this Austin project. Exposed-fastener R-panel handles heavy rain and hail without the granule loss shingles can suffer. The metal panels give the porch a crisp, low-maintenance finish that pairs well with the new shingle roof. Metal is a smart pick for Austin's mix of sun, storms, and cedar pollen.

The homeowner found us through an internet search and reached out on June 20, 2023. They had storm damage on the roof and wanted a contractor who could handle an insurance claim. We set up an inspection to document the hail damage and map out a plan.
By late June, we were up on the roof taking a close look. We found hail bruising across the shingles and a worn screened-porch covering that no longer shed water well. The gutters checked out fine, so we flagged them for detach and reset rather than replacement. That inspection became the basis of the estimate.
We built the scope around GAF Timberline HDZ SG shingles for the main roof and R-panel metal for the porch. The homeowner approved the project on July 17, 2023. Since this was an insurance job, we coordinated the paperwork so the covered storm damage was clearly documented.
This was a multi-day install. The crew tore off the old comp shingles, hauled them away, and rebuilt the system with FeltBuster underlayment, StormGuard, and 7,200 coil nails. We installed the ProStart starter, Timbertex ridge caps, and Cobra ridge vent, then set the R-panel metal over the screened porch and reset the gutters.
We completed the roof on August 28, 2023, and walked the property to confirm every detail was buttoned up. The finished system carries the GAF Golden Pledge Warranty, GAF's strongest coverage.
We replaced the full shingle roof and the screened-porch metal roof on this Colony North home in Austin, TX. The result is a storm-ready system built to handle Central Texas hail, heat, and driving rain.
The roof had taken a beating from a Central Texas hailstorm, and this was an insurance claim. Many homes in this part of Austin date to the 1980s and 90s, so their original roofs are well past their prime.
Here's what pushed the project forward:
Once we were up on the roof, the hail bruising was clear across the field of shingles. That kind of damage cracks the mat and speeds up granule loss, which then exposes the asphalt to Austin's brutal UV. We also looked closely at the screened porch, where the old covering had worn thin and no longer shed water the way it should. The gutters were solid, so we planned to detach and reset them rather than replace. That inspection shaped the whole scope, from the tear-off plan to the choice of metal over the porch.
We installed GAF Timberline HDZ SG shingles as the main system. These architectural shingles have a wide nailing zone that speeds up install and holds firm in high wind.
The full assembly included:
Synthetic underlayment matters here. Old felt paper can tear and trap heat, and in a 100-degree Austin attic that shortens a roof's life. FeltBuster stays stable and adds a second line of defense under the shingles.
The porch called for something tougher than asphalt, so we went with R-panel metal roofing. Exposed-fastener R-panel is one of the most practical metal profiles for a porch or patio structure. It sheds water fast, shrugs off hail that would dent or crack shingles, and needs almost no upkeep. Metal also handles the cedar pollen and pooling debris that Austin springs throw at low-slope roofs. Pairing metal over the porch with shingles over the main house gave this home the right material in the right place.
This was a multi-day job that we wrapped on August 28, 2023. We tore off the old comp shingles, hauled everything away, and rebuilt the system from the deck up.
Key steps on site:
With proper venting and the Golden Pledge Warranty, these architectural shingles are built for decades of Central Texas sun and storms. The Cobra ridge vent we added helps the attic breathe, which protects the shingles from heat buildup.
This job fell in the $20,000 to $25,000 range and was handled as an insurance claim. Storm-damage roofs in Austin often qualify, so it's worth having a contractor document the hail damage for you.
Yes, for a screened porch or patio cover, R-panel metal usually outlasts shingles and resists hail dents better. It's a clean, low-maintenance finish that pairs well with a shingle main roof.
We finished the work on August 28, 2023, after the claim was approved in July. The file closed out in October 2023 once everything was invoiced and reviewed. If you want the same crew for your roof, reach out to Austin Pro.
