Exposed-Fastener Metal Roofing
Corrugated & R-Panel Metal Roofing for North Texas
Corrugated and R-panel steel is the value end of metal roofing: quick to install, typically Class A fire-rated as an assembly, and at home on barndominiums, shops, ranch barns and a growing number of houses across North Texas. We install it to the manufacturer’s fastening schedule and tell you honestly where standing seam is worth the upgrade.

What is corrugated and R-panel metal roofing?
Both are exposed-fastener steel panels: long sheets screwed through the face into wood purlins, steel purlins or a solid deck, with a rubber-washer screw sealing every hole. Corrugated has the classic rounded wave. R-panel uses tall trapezoidal ribs with flat pans between them, and PBR (purlin bearing rib) adds a bearing leg along the overlap so the side lap sits on the purlin and stays tight. Many DFW homes and barndominiums use R-panel or PBR for strength and a cleaner line, while corrugated suits a rustic or modern-farmhouse look.
Who is corrugated metal roofing right for?
It is right for buildings where cost, speed and toughness matter more than a hidden-fastener finish. We install it on four kinds of projects:
Homes
Modern farmhouse and ranch-style houses, porch and patio covers, and accent roofs. Best on unrestricted lots, since HOAs often push back on exposed fasteners.
Barndominiums
Living space and shop under one roof, common across Parker, Wise, Denton, Ellis and Johnson counties. We plan condensation control and closures so the living side stays dry.
Shops, garages and carports
Detached workshops, RV covers and carports where long spans and fast installs matter. Seamless gutters on the eaves keep runoff off the slab.
Ranch and ag buildings
Hay barns, loafing sheds and equipment barns around Weatherford, Denton and Ellis County. Many Galvalume warranties exclude enclosed livestock buildings, so we match the substrate to the use.
Corrugated vs. standing seam: which is better?
Standing seam is the better long-term roof for a primary home. Exposed-fastener panels win on cost and speed and are often the right call for shops, barns and budget-minded barndominium builds.
| Factor | Corrugated / R-panel | Standing seam |
|---|---|---|
| Typical installed price (2026) | About $5.50-$11.50 per sq ft in Texas | Typically $10-$18 per sq ft |
| Fasteners | Thousands of screws through the panel face | Concealed clips, no holes through the panels |
| Thermal movement | Pinned at every screw; holes can elongate on long runs | Floating clips let panels expand and contract |
| Maintenance | Screw and washer check, typically at 10-15 years | Periodic inspection |
| Solar mounting | Sealed brackets through the ribs | Clamp-on, no penetrations |
| Best for | Shops, barns, carports, many barndominiums | Primary homes, low-slope porches, solar plans |

How do we install exposed-fastener metal so it lasts in Texas?
The details decide whether an exposed-fastener roof lasts or leaks: gauge, coating, screws, closures and condensation control.
- Gauge. We recommend 26-gauge as the floor for homes and barndominiums, and 24-gauge (about 28% thicker) where hail exposure justifies it. A quality 26-gauge panel can still carry UL wind, fire and Class 4 impact ratings; we confirm the rating on the exact product.
- Substrate and paint. Galvalume (AZ50 under paint, AZ55 bare) suits inland DFW. Kynar 500 PVDF holds color longest; SMP is fine on light colors and budget buildings but fades and chalks sooner.
- Screws. Long-life screws with EPDM washers, driven snug but never crushed, placed where the manufacturer specifies, with tighter spacing at edges and corners where wind uplift peaks.
- Laps and closures. Butyl tape at laps on lower slopes and foam closures at eaves and ridge to stop wind-driven rain, wasps and birds.
- Underlayment or condensation control. Over a solid deck, high-temperature synthetic underlayment rated to 240°F or more. Over open purlins, DFW’s average humidity of about 62% means bare steel can drip on cool nights, so we add drip-stop backing, a vapor retarder or insulation.
How does corrugated metal handle DFW hail, wind and heat?
Well, with honest caveats. Steel panels do not crack or shed granules, but large hail can dent any metal, and exposed fasteners need periodic attention in Texas heat.
Texas has led the nation in major hail events for 11 straight years, and on April 28, 2026 preliminary reports put 4.5-inch hail near Cresson and Godley, ranch country south of Fort Worth. No roof is immune to stones that size. Dents that still shed water are typically cosmetic, and many policies exclude cosmetic hail damage to metal roofs, so read your endorsement. A TDI-recognized impact-resistant credit requires a panel tested to UL 2218, and the credit amount is up to your carrier.
Wind is a fastening question. March 2025 brought 105 mph straight-line winds to Haltom City and 90 mph winds that collapsed a warehouse wall in Richland Hills; the manufacturer’s screw pattern at edges, corners and ridges keeps panels on. Heat is the slow threat: about 20 days a year at or above 100°F cycle the steel, elongating screw holes and aging washers, so we recommend a fastener check after major storms and around year 10.
Will an HOA approve a corrugated metal roof?
Often not easily. Texas Property Code §202.011 protects wind- and hail-resistant shingles that resemble the neighborhood’s roofs, not exposed-fastener panels, so deed-restricted subdivisions may say no. Unrestricted lots in Parker, Wise, Ellis and Kaufman counties are where corrugated fits best. Inside an HOA, consider metal shingles instead.
How much does a corrugated metal roof cost in DFW (as of 2026)?
Exposed-fastener and basic metal profiles typically run about $5.50 to $11.50 per square foot installed in Texas as of 2026, compared with about $5.00-$8.50 for architectural shingles and typically $10-$18 for standing seam. What moves your price:
- Gauge (26 versus 24) and paint system (SMP versus PVDF)
- Tearing off an old roof versus new construction over purlins
- Trim package: ridge, rake, eave trim and closures
- Condensation control and insulation
- Building height, pitch and site access

When should you choose corrugated, standing seam or something else?
Choose corrugated or R-panel for shops, barns, carports and budget-focused barndominiums. Choose standing seam for a primary home you plan to keep, especially if solar panels are in your future. In an HOA, metal shingles or Class 4 asphalt shingles clear review more easily. Already have an exposed-fastener roof that leaks? Our roof repair crews re-fasten and reseal metal panels.

What Dallas-Fort Worth Homeowners Say About Texas Metal Panels
Corrugated and R-panel roofing FAQ
What is the difference between corrugated and standing seam?
Corrugated and R-panel roofs are fastened with exposed screws through the panel face. Standing seam hides its fasteners under raised, interlocking seams on clips that let the metal move. Exposed-fastener roofs cost less and go up faster; standing seam lasts longer with less maintenance.
How much does a corrugated metal roof cost?
As of 2026, exposed-fastener and basic metal profiles typically run about $5.50 to $11.50 per square foot installed in Texas. Gauge, paint system, tear-off versus new construction, trim and condensation control move the number, and we quote in writing from measurements or your plans.
Do exposed fastener roofs leak?
Not when they are installed and maintained correctly, but the screws are the weak point. Rubber washers degrade under UV and heat cycling and typically need attention in 10 to 15 years. Replacing or re-seating screws on schedule keeps the roof dry.
How long does a corrugated metal roof last?
Metal roofs commonly last 40 years or more in Texas, and painted Galvalume substrates typically carry warranties of up to about 50 years. The fasteners are the maintenance item, usually needing attention at 10 to 15 years, so plan a screw check on that schedule.
Can you put corrugated metal over shingles?
Sometimes, over a single sound layer with purlins or battens, where local code and the permit office allow it. On DFW homes we usually recommend a tear-off, because hail-worn shingles can hide rotten decking and a tear-off lets us fix the deck before the new roof goes on.
Is R-panel good for a house roof?
It can be, especially on modern farmhouse, ranch and barndominium-style homes on unrestricted lots. Use 26-gauge or heavier, a PVDF finish for color retention, and proper underlayment over a solid deck. For a long-term primary home, standing seam is the lower-maintenance upgrade.
What roof works best for a barndominium in North Texas?
PBR or R-panel is a common, economical choice, and standing seam over the living area is a popular upgrade. Either way, plan condensation control, closures, gutters and the fastening schedule up front so the living side stays dry and quiet.
