James Hardie HardiePlank Select Cedar Mill Fiber Cement Re-Side | Complete GAF Timberline HDZ Shingle Roof Replacement
This Cedar Park project centered on a full re-side using James Hardie HardiePlank Select Cedar Mill fiber cement in the 8.25-inch profile, a material that stands up to 100-degree summers, hail, and the moisture swings that warp lesser products. We installed both primed and finished Select Cedar Mill planks, painted the new siding, and refreshed the fascia and soffit up to 24 inches for a clean, uniform exterior. Fiber cement was the right call for an aging home in the 78613 area because it resists rot, pests, and the expansion-contraction cycle that comes with our limestone-soil climate. The result is a low-maintenance, hail-resistant facade that should look sharp for decades. Anyone researching siding in Cedar Park, TX will find this is the kind of upgrade that pays off through Texas weather extremes.

The secondary scope was a complete shingle roof replacement using GAF Timberline HDZ architectural shingles, including a full tear-off, haul-off, and disposal of the old comp shingles. We layered the system properly with GAF FeltBuster synthetic underlayment across 10 squares, ProStart starter strip along the eaves at 120 feet, galvanized steel drip edge, and GAF Z-Ridge ridge cap at 33 feet. Sheathing and OSB decking were replaced where needed using 7/16-inch 4x8 panels, and everything was sealed with Geocel construction sealant. For shingle roofing in Cedar Park, TX, the Timberline HDZ system delivers the wind and impact performance these hail-prone neighborhoods demand.
This was a returning client who had worked with Austin Pro before, so when their home's exterior started showing wear, they reached out to us directly. The lead came in on June 6, 2023, and we moved them into our prospect pipeline the very next day, June 7. From the first conversation, the homeowner wanted both the siding and the roof handled together under one crew.
Our assessment of the Cedar Park property covered both the walls and the roof. The original siding was worn from years of Texas heat and hail, and the fascia and soffit needed attention up to 24 inches. On the roof, the comp shingles were near end-of-life and portions of the decking needed evaluation for replacement, which is common for homes of this era in 78613.
We built out a combined scope covering James Hardie HardiePlank Select Cedar Mill siding and a full GAF Timberline HDZ roof replacement, including underlayment, starter strip, ridge cap, and decking allowances. The homeowner reviewed and approved the project on July 8, 2023. From there we coordinated material orders and crew scheduling around availability.
The full installation was executed on October 26, 2023. The crew tore off the old comp shingles with haul-off and disposal, replaced compromised 7/16-inch OSB decking, dried in the roof with GAF FeltBuster underlayment, and installed Timberline HDZ shingles with ProStart starter and Z-Ridge cap. In parallel, the siding crew installed the 8.25-inch Select Cedar Mill planks, sealed joints with Geocel, and painted the siding and fascia.
We finished with two rounds of yard cleanup and a final punch-out to ensure the site was left spotless — no stray nails or debris. The project completed and invoiced on October 26, 2023, delivering a hail-resistant fiber cement exterior and a fully rebuilt GAF roof system. We kept the file open through follow-up and closed it out clean on January 4, 2024.
This one came back to us. The homeowner on Shenandoah Drive in Cedar Park had worked with Austin Pro before, and when the exterior of the house started showing its age, they called us first. That kind of repeat trust is something we don't take lightly.
The house sits in the 78613 corridor, the kind of late-90s-into-2000s build that's all over this part of Williamson County. The siding was tired. The roof was aging out. Rather than chase two separate contractors on two separate timelines, the homeowner wanted both handled together, by one crew, with one point of accountability. We labeled the job APS-3752 and got to work.
The lead came in on June 6, 2023. We had them flagged as a prospect by June 7, and the project was approved July 8. We coordinated material and crew scheduling around availability, and the full installation was knocked out in a single concentrated push on October 26, 2023.
When we assessed the property, two things stood out.
The original siding had taken a beating from Central Texas weather. Years of 100-degree summers and the occasional hail event leave their mark, and the existing material wasn't holding up to the expansion-and-contraction cycle our limestone-soil climate puts every house through. The fascia and soffit also needed attention up to about the 24-inch mark.
The roof told a similar story. The existing comp shingles were near the end of their service life, and parts of the decking needed evaluation for replacement. In a region that gets hit with hail regularly, a marginal roof is a risk you don't want to carry.
Our recommendation was straightforward: full re-side with fiber cement, and a complete tear-off and roof replacement. Do it right, do it once.
For the siding, we went with James Hardie HardiePlank Select Cedar Mill in the 8.25-inch profile. There's a reason this is our go-to for Cedar Park homes.
Fiber cement doesn't rot. It doesn't feed pests. It doesn't warp when the thermometer swings 40 degrees in a single Texas day. And critically for this area, it holds up to hail far better than older siding materials. The Select Cedar Mill texture gives the house a warm, woodgrain look without any of the maintenance headaches that come with actual wood.
The scope included:
Proper installation matters as much as the material. Fiber cement has to be cut, gapped, and fastened correctly, with sealant at the right transitions, or you lose the longevity it's known for. Our crew handled the detail work, and we coordinated finish coatings through Sherwin Williams for a durable paint system.
On the shingle roofing side, we did a complete R&R of the comp shingles with haul-off and disposal, then rebuilt the roof as a full system using GAF Timberline HDZ architectural shingles.
A roof is only as good as the layers underneath the shingles, so we didn't cut corners on the components:
The Timberline HDZ line is built for exactly the wind and impact conditions Cedar Park throws at a roof. Paired with a properly installed underlayment and starter system, it's a roof designed to ride out the storms that roll through Williamson County every spring.
The coordination here is what made this project work. Materials came through suppliers including Home Depot and ABC Supply, and the whole job was managed through our production system so the siding and roofing crews stayed in sync.
We staged decking and shingle material, executed the tear-off, replaced compromised OSB, and dried the roof in with underlayment before the shingle install. The siding crew worked the walls in parallel where it made sense. We wrapped with two rounds of yard cleanup and punch items, plus a final punch out to make sure nothing was left behind — no stray nails, no debris, a clean site handed back to the homeowner.
Installation completed on October 26, 2023, and the project invoiced the same day. We kept the file open through follow-up and closed it out clean on January 4, 2024.
If you own a home built in the late 90s or 2000s in the 78613 area, you're likely staring down the same two items: original siding that's reaching its limit and a roof that's aging out. Tackling them together saves you a second mobilization, a second cleanup, and a second round of scheduling headaches.
Fiber cement siding and a GAF architectural roof are both built for our specific punishment — relentless summer heat, sudden hail, and soil that never sits still. This homeowner gets a hail-resistant, low-maintenance exterior that should look sharp for decades.
If you're weighing a similar project, or you want to add gutters or exterior painting into the mix, we're happy to walk your property and tell you straight what it needs. No pressure, just an honest assessment from a crew that's done this work all over Central Texas.
