Exposed Fastener & Corrugated Metal Roofing in Austin
Corrugated and ribbed metal panels screwed through the face are the most economical way to put a metal roof on a building. They're a Central Texas staple on shops, barns, porches and Hill Country homes. Here's how exposed fastener metal roofing works, where it makes sense, and what it takes to keep it tight for the long run.

- Fasteners need periodic checking and replacement as washers age in the sun.
- It suits shops, barns, porches, outbuildings and budget-minded re-roofs.
Corrugated vs. ribbed panels
Corrugated
The classic wavy profile. Common on barns, porches, accent roofs and Hill Country-style homes, and available in Galvalume and painted finishes.
Ribbed panels (R-panel, PBR)
Trapezoidal ribs give more strength across longer spans, which is why they're common on shops, garages and light commercial buildings.
Galvalume or painted
Both profiles come in bare Galvalume or painted steel. Painted finishes add color and can reflect more heat. See Galvalume vs. painted.
Galvalume metal roofingTrim and closures
Ridge caps, eave trim and foam closures keep wind-driven rain and pests out of the panel ribs. They matter as much as the panels.

Why installation decides how long it lasts
With an exposed fastener roof, every screw is a potential leak. Screws driven at an angle, overtightened so the washer splits, or undertightened so it doesn't seal are the usual causes of leaks on these roofs, often years later. Correct fastener placement, the right screws for the panel and substructure, and proper laps and closures are what separate a roof that stays tight from one that drips.
Over time, the rubber washers age in the Texas sun and screws can back out as panels expand and contract. Regular metal roof maintenance catches that early, and on older roofs, a coating restoration can add years. When a roof is past that point, we handle metal roof replacement.

Frequently asked questions
Is corrugated metal good for a house?
It can be, especially for Hill Country and farmhouse styles, as long as it's installed carefully and the fasteners are maintained. Many homeowners choose standing seam for lower long-term upkeep.
How long do exposed fastener metal roofs last?
The panels can last for decades. The fasteners and washers are the weak point and typically need attention well before the panels do.
Do exposed fastener roofs leak?
They can, usually at fasteners that were installed incorrectly or have aged. Correct installation and periodic fastener checks prevent most leaks.
Is exposed fastener cheaper than standing seam?
Yes. Materials cost less and installation is faster, which is why it's the budget option for metal roofing.
