Metal Sales positions itself as the nation’s largest manufacturer of metal roofing and wall systems. They’ve been at it for over 60 years, operating 21 manufacturing facilities across the country. The brand targets professional contractors in commercial, agricultural, and residential construction with what they claim are “one of the highest quality metal panels on the market.”
Skip their metal panels if you’re just re-roofing a basic residential job with budget constraints. Asphalt shingles cost less upfront and any roofer can install them. Metal Sales makes sense when longevity matters, when the building faces extreme weather, or when fire resistance drives the decision.
Standing Seam and Concealed Fastener Systems
The Magna-Loc systems use concealed fasteners with a 3:12 minimum slope requirement. That concealed design eliminates the weak points where exposed fasteners penetrate the panel — no rubber washers to fail, no screw holes to leak. These panels install over solid substrate with 30# felt underlayment.
The concealed fastener approach costs more than exposed systems but delivers genuine performance advantages. No fastener maintenance. No re-tightening screws every few years. The panels interlock to create a weathertight seal that handles thermal movement without stressing penetrations.
Metal Sales offers features contractors actually care about: low maintenance, easy installation, full line of trims and accessories, highly resistant to wind, hail, snow and rain, mildew resistant and will not rot or absorb water. That’s not marketing fluff — those are the exact reasons contractors choose metal over asphalt.
Exposed Fastener Panel Options
The exposed fastener lines come in both 29 and 26 gauge options. These panels work for agricultural buildings, shops, and budget-conscious projects where the concealed fastener premium doesn’t pencil out.
| Panel Type | Gauges | Coverage | Minimum Slope |
|---|---|---|---|
| R-Panel | 29 & 26 | 36” | 3:12 |
| PBR-Panel | 29 & 26 | 36” | 1:12 |
| Mesa | 29 | 24” | 3:12 |
| Multi-Rib | 29 | 21-1/3” roof, 24” wall | 3:12 |
The 29 gauge handles most applications fine unless you’re dealing with exceptional snow loads or spans.
PBR-Panel drops to 1:12 minimum slope — useful for those nearly-flat commercial roofs where drainage matters but steep pitch isn’t practical. The Multi-Rib offers different coverage for roof (21-1/3”) versus wall (24”) applications, with 1/2” rib height.
Code Compliance and Testing
Metal Sales backs their reputation with specific ICC-ES compliance reports and Florida Building Code approvals for high-wind zones. Their products meet requirements for High Velocity Hurricane Zones including Miami-Dade County approvals. The company claims 40-70 year lifespans for their systems.
Specific Florida approval numbers include 14645.6 and 14645.8. Those aren’t just paperwork — they represent actual testing for wind uplift, water penetration, and structural performance. Products undergo evaluation and certification by ICC Evaluation Service (ICC-ES), with detailed reports like ESR-2385-25 that verify product performance, installation guidelines, and code compliance.
Montana contractors might wonder why Florida approvals matter here. Simple: if a panel survives Miami-Dade testing, it’ll handle whatever weather Montana throws at it. The testing protocols for hurricane zones exceed anything required for snow country.
Metal Sales emphasizes their 45-year finish warranties backed by superior protective coatings. They incorporate up to 30% recycled steel content and offer over 100 ENERGY STAR listed colors. The recycled content matters for LEED projects. The color selection matters because nobody wants to explain why the barn has to be red or white.
The Bottom Line
Metal Sales positions their products as “one of the highest quality metal panels on the market” with complete roof system solutions from underlayment to ventilation accessories. They back it up with legitimate testing data, code approvals, and a 45-year finish warranty that beats most competitors.
The exposed fastener panels work fine for basic agricultural and storage buildings. Step up to concealed fastener systems when the building matters more — commercial projects, high-end residential, anywhere that maintenance access proves difficult. Their code compliance documentation helps contractors satisfy inspectors and insurance companies.
Metal Sales operates like a commercial supplier, not a retail brand. You won’t find weekend warrior products or homeowner-friendly packaging. This is contractor-grade material backed by the testing data professionals need.
Frequently Asked Questions
Q: What’s the actual difference between 29 gauge and 26 gauge panels? A: Both gauges are available in most Metal Sales exposed fastener systems. The 26 gauge measures about 15% thicker, handles longer spans, and resists denting better. Most agricultural and residential projects run fine on 29 gauge unless you’re spanning unusual distances or facing exceptional snow loads.
Q: Do Metal Sales panels really last 40-70 years? A: The company claims 40-70 year lifespans for their systems. They back this with 45-year finish warranties and superior protective coatings. The steel itself lasts that long — the coatings and fasteners determine real-world lifespan. Concealed fastener systems eliminate the weak point of exposed screws, making 40+ years realistic with minimal maintenance.
Q: Can I install Metal Sales roofing over existing shingles? A: Their specifications call for installation over solid substrate with 30# felt underlayment. That typically means removing old roofing first. Some jurisdictions allow metal-over-shingle installation with proper furring strips, but you’ll need local code approval and it may void warranties.
Q: What makes Metal Sales different from other metal roofing brands? A: They claim to be the nation’s largest manufacturer with 21 facilities and over 60 years of experience. Their products carry specific ICC-ES reports and Florida Building Code approvals including Miami-Dade County certification. The real differentiator is documentation — they provide the testing data commercial contractors need for code compliance.
