What are exposed-fastener metal panels?
They are corrugated or ribbed steel sheets fastened with screws driven straight through the face into purlins or a roof deck. Each screw head stays visible and is sealed by a rubber washer.
That simple attachment is why they cost less and go up faster than standing seam, which hides its clips under raised seams. It is also why they need more upkeep, which we cover honestly below.
We offer five profiles in this family. Two are round-wave corrugated panels, one is a tall-rib industrial panel, and two are 36-inch PBR-style panels. The right one depends on the look you want, how far the panel must span, and whether it goes on a roof or a wall.
Which exposed-fastener profile do you need?
Each profile has its own page with a spec table, best uses and installation notes. Start with the one that matches your building.
2.67″ x .5″ Corrugated Panel
The traditional shallow wave. It suits porch roofs, wainscot, accent walls and farmhouse-style outbuildings.
2.67″ x .875″ Corrugated Panel
A deeper 7/8-inch wave with bolder shadow lines and more stiffness. Architects like it for commercial siding.
7.2 Rib Panel
Tall ribs on 7.2-inch centers. This is the heavy-duty choice for warehouses, big shops and metal buildings.
PBR Panel
The 36-inch workhorse with a purlin bearing leg under each side lap. It is the standard barn and barndominium roof.
RPBR Panel
The PBR profile formed in reverse, so panels lap in the opposite direction when the layout calls for it.
How do the five profiles compare?
These are typical industry dimensions for each profile. Exact coverage, gauge and slope limits come from the panel’s published load tables, and your shop drawing confirms them before anything is cut.
| Profile | Look | Rib or wave height | Net coverage (typical) | Common gauges | Strongest fit |
|---|---|---|---|---|---|
| 2.67″ x .5″ corrugated | Classic round wave | 1/2 in. | About 37 in. roof, 40 in. wall | 26 or 24 ga steel | Porches, wainscot, accent walls |
| 2.67″ x .875″ corrugated | Deep round wave | 7/8 in. | About 32 in. roof, 34-2/3 in. wall | 24 or 22 ga steel | Commercial siding, longer spans |
| 7.2 rib | Tall trapezoid ribs | About 1-1/2 in. | About 36 in. | 26, 24 or 22 ga steel | Warehouses, metal buildings |
| PBR | Square ribs with bearing leg | About 1-1/4 in. | About 36 in. | 26 or 24 ga steel | Barns, barndominiums, shops |
| RPBR | PBR formed in reverse | About 1-1/4 in. | About 36 in. | 26 or 24 ga steel | Opposite-direction layouts |
Two notes for buyers. Corrugated panels cover less on roofs than on walls, because roofs need a wider side lap to shed wind-driven rain. And every figure above is a typical value, so ask us for the exact data sheet that matches your order.
Where do exposed-fastener panels make sense in DFW?
They fit buildings where budget and speed matter more than a fastener-free look. Across Dallas-Fort Worth, that usually means the list below.
- Shops and garages, from weekend workshops to RV covers on acreage lots.
- Barns and stables, including hay barns, horse barns and equipment sheds.
- Barndominiums, usually with a PBR roof and a contrasting wainscot on the walls.
- Porches and patios tied into a house that has a different main roof.
- Carports and open-sided steel frames where panels span between purlins.
- Agricultural buildings such as feed storage, loafing sheds and pump houses.
- Pre-engineered metal buildings for warehouses, small businesses and churches.
- Wainscot and wall panels on new builds and on re-skins of tired metal walls.
They are a harder sell on the main roof of a house in an HOA neighborhood. Many DFW deed restrictions limit visible fasteners on the primary home, and standing seam or metal shingles usually win approval more easily. On rural acreage with no HOA, the choice is yours.
Mixing systems is common and sensible. A home might carry a standing seam roof while the detached shop and back porch use PBR or corrugated panels in a matching color.
Exposed fastener or standing seam: which should you choose?
Choose exposed-fastener panels for outbuildings, tight budgets and speed. Choose standing seam for a home you plan to keep for decades. The difference comes down to what holds each panel down.
| Factor | Exposed-fastener panels | Standing seam |
|---|---|---|
| Attachment | Screws through the panel face | Hidden clips under raised seams |
| Thermal movement | Screws resist it, so holes can slowly elongate | Floating clips let panels slide |
| Routine upkeep | Periodic screw and washer checks | Very little |
| Minimum slope | 3/12 is common for corrugated; ribbed profiles go lower with sealed laps | 3/12 snap lock, 1/2:12 mechanical lock |
| Look | Agricultural to industrial | Clean and architectural |
| Up-front cost | Lower | Higher |
| PMRS warranty | Written terms on your quote | Lifetime Non-Prorated Limited Warranty on PMRS standing seam roofs |
Price matters here, so here is a reference point. On a house, our installed standing seam in 24-gauge Kynar 500 is currently about $15 per square foot of roof. Exposed-fastener systems generally land below that, depending on gauge, finish and framing. Our metal roof cost guide explains what moves the number.
Weighing the concealed-fastener options too? Compare snap lock with mechanical lock standing seam.
How much maintenance do exposed fasteners need in Texas?
More than standing seam, and you should know that before you buy. Every screw is a small hole sealed by a rubber washer, and North Texas sun is hard on rubber.
Dallas summers routinely bring a UV index of 9 to 10. DFW also averages about 20 days a year at 100 degrees or hotter. Each day the panels heat, stretch and cool again. Over the years that cycle hardens the washers, can back screws out slightly and can wallow out holes on long runs.
Industry experience puts the first round of fastener work at roughly 10 to 15 years. A simple routine keeps the roof tight:
- Look over the roof once a year and after any hailstorm or high-wind event.
- Watch for cracked or flattened washers, tilted screws and rust around screw heads.
- Snug loose screws gently, and replace stripped ones with the next size up.
- Keep laps, valleys and gutters clear so water never sits at a fastener line.
Installation quality decides how soon that day comes. We drive screws square, seat each washer without crushing it and keep fasteners on the pattern the panel maker tested.
How do these panels handle DFW hail, heat and humidity?
They hold up well when the gauge and details are right. Texas has led the nation in major hail events for 11 straight years, according to NICB analysis, so gauge is the first decision.
Thicker steel dents less. A 24-gauge panel is roughly 28 percent thicker than 26 gauge, and ribs or corrugations add stiffness that helps hide minor dimpling. If you want an insurance credit, ask for the manufacturer’s UL 2218 listing for that exact panel and gauge. The Texas Department of Insurance leaves the size of any credit to each carrier.
For heat, a light or cool-pigment finish reflects more sun and keeps a shop cooler inside. PVDF finishes such as Kynar 500 hold their color longer than SMP in hard sun. Our PVDF coatings guide compares them.
Humidity is the hidden issue on open-framed buildings. DFW averages about 62 percent relative humidity, so bare panels over purlins can drip condensation on cool mornings. A faced insulation blanket or vapor retarder under the panels prevents it.
How does PMRS supply and install exposed-fastener panels?
We treat a barn or shop like any other roof system. It is measured, drawn, fabricated and installed by one company.
- Panels cut to the length of each run, so most slopes need no end laps.
- Ridge caps plus rake, eave, corner and base trim bent on our computerized folders.
- Profile-matched foam closures at eaves and ridges to stop wasps, birds and blown rain.
- Color-matched self-drilling screws with sealing washers on the tested pattern.
- Gutters and downspouts sized for heavy Texas downpours, covered on our gutters page.
Pick colors from our metal roof color chart. The 2.67″ x .5″ corrugated panel is also listed in crinkle and Tedlar finishes. Sealants, pipe boots and underlayment are on the accessories page.
Contractors can order panels and trim by the job, with shop drawings when a project needs them. Our services page covers materials supply and estimating.
Homeowner Reviews
What Dallas-Fort Worth Homeowners Say About Permanent Metal Roofing Systems
Corrugated and Exposed-Fastener Panel Questions
Is corrugated metal a good roof for a house in Dallas?
It can be, especially on farmhouse or rustic designs on acreage. The trade-offs are exposed screws that need periodic checks and HOA rules that often favor concealed fasteners. For a primary home in a subdivision, most owners choose standing seam. For porches, shops and accent roofs, corrugated is a strong value.
Is PBR the same as R panel?
They share a 36-inch footprint and a similar rib pattern. The difference hides in the side lap: PBR adds a flat ledge along one edge that bears on each purlin and props up the neighboring rib. R panel has no ledge, so its lap is weaker. Our PBR panel page has the full specs.
How long do exposed-fastener metal roofs last in Texas?
The steel panels can last for decades with a quality finish. The weak point is the rubber washer under each screw, which typically needs attention after roughly 10 to 15 years in Texas sun. Replacing tired screws is routine maintenance, not a new roof, and it costs far less when caught early.
What is the minimum slope for corrugated metal roofing?
Corrugated panels are typically installed at 3/12 or steeper. Taller ribbed panels such as PBR and 7.2 rib are often allowed on lower slopes when side and end laps are sealed, per the manufacturer. On very low slopes, a mechanically seamed standing seam roof rated to 1/2:12 is the safer choice.
Do you sell corrugated and PBR panels to contractors?
Yes. Contractors and builders can order panels cut to length with matching trim, closures and fasteners. Send plans or measurements and we will return a take-off and a written quote. Delivery is available across Dallas-Fort Worth, and our services page explains materials supply.
Which panel works well for a barndominium?
Most barndominiums around DFW use PBR on the roof for its span and side-lap strength. Walls are often PBR or corrugated, with a wainscot band in a contrasting color. If the living area sits under the roof, consider 24 gauge for hail and a high-temperature underlayment over a solid deck.
Are exposed-fastener panels Class 4 hail rated?
Some exposed-fastener assemblies carry UL 2218 Class 4 ratings, but each rating belongs to a specific tested panel, gauge and fastening method. Ask for the manufacturer’s listing for your exact panel. Each insurer decides whether it offers a credit and how large that credit is.
