Metal Roof Replacement in Granada Estates, Southwest Austin

The homeowner in Granada Estates, Southwest Austin, needed a new roof because their insurance carrier would not renew their policy. The 40-year-old, 26-gauge Texas Rib metal roof was badly rusted, its exposed fasteners were backing out, and the panels sat on 1×4 purlins with no solid roof deck. We installed 7/16-inch radiant barrier sheathing over the purlins on the house and garage, then replaced the roof with a 24-gauge ShurLoc 150 standing seam metal roof in Galvalume with a vented ridge, completed in 5 days.

The Situation

The homeowner needed a new roof because their insurance carrier would not renew their policy. The house and garage still had a 26-gauge Texas Rib metal roof with exposed fasteners, and it was about 40 years old.

What We Found

Extensive rust on the 26-gauge Texas Rib metal panels.
The exposed fasteners were backing out. On an exposed-fastener roof, every screw goes through the face of the metal panel, so each one that backs out leaves a hole where water can get in.
In the attic, the panels were fastened to 1×4 purlins running across the rafters, 11in on center, with no solid roof deck underneath.

What We Installed

Tore off the old Texas Rib metal panels and exposed fasteners, leaving the 1×4 purlins in place.
Installed West Fraser SolarBord 7/16-inch radiant barrier OSB sheathing over the purlins on the entire house and garage, giving the roof its first solid deck.
Installed Palisade synthetic underlayment over the entire deck.
Installed high-temperature ice and water barrier at the pipe penetrations, the chimney and the sidewalls.
Notched the garage eave to make room for a tree.
Installed 24-gauge ShurLoc 150 standing seam panels in AZ-55 Acrylic Galvalume, with 1½-inch snap-together seams and one-piece clips that let the panels expand and contract with the heat. The clips are hidden under the seams, so no screws go through the face of the panels.
Installed new chimney flashing and Dektite pipe flashings.
Installed a vented ridge along the top of the roof so hot air can escape from the attic.

The Result

The house and garage now have a solid roof deck for the first time and a 24-gauge standing seam metal roof with no exposed fasteners to back out. The panel system is rated Class 4 for impact and Class A for fire. The homeowner now has beautiful new metal to replace the 40-year-old roof that put their insurance policy at risk.
