Types of Metal Roofing We Install

Standing Seam Metal Roofing

The premium choice in metal roofing. Standing seam panels interlock with concealed fasteners — no exposed screws, no penetration points for water intrusion. This system is ideal for Maryland homeowners seeking maximum longevity and a sleek, modern appearance. Standing seam metal roofs carry 40–50 year warranties.

Metal Shingles

Metal shingles replicate the look of asphalt, slate, or wood shake roofing while delivering the durability of steel or aluminum. Perfect for homeowners in historic neighborhoods or HOA communities in Montgomery and Howard County who want metal performance with a traditional aesthetic.

Corrugated Metal Roofing

A cost-effective metal option commonly used for garages, outbuildings, and commercial applications. Corrugated panels are lightweight, durable, and install quickly — a practical solution for Maryland property owners on a tighter budget.

Benefits of Metal Roofing in Maryland

Frequently Asked Questions — Metal Roofing in Maryland

Detailed answers for Montgomery County homeowners considering standing seam metal roofing in Rockville, Gaithersburg, Potomac, Germantown, and surrounding areas.

What is standing seam metal roofing and how does it differ from exposed-fastener metal?

Standing seam metal roofing uses panels with raised interlocking seams along their length — the seams clip or snap together and are hidden above the panel surface, eliminating all exposed fasteners. No screws penetrate the panel face, so there are no penetration points that can rust, back out, or leak over decades. Exposed-fastener metal (corrugated or R-panel) uses screws through the panel face with rubber washers that degrade in 10–15 years, eventually leaking at each fastener. For Montgomery County residential installations in zip codes 20850–20878, ARHT installs concealed-fastener standing seam systems only — Fabral, McElroy, and Metal Sales — which are warrantied for 50 years structural and 40 years paint. Exposed-fastener systems are appropriate for outbuildings and garages, not primary residential roofs.

What metal roofing systems does ARHT install in Montgomery County?

ARHT installs three manufacturer systems for residential standing seam metal roofing in zip codes 20850–20878: Fabral (Grand Manor and Horizon series), McElroy Metal (Meridian and 238T series), and Metal Sales (Classic Rib and Standing Seam series). All three are available in Galvalume steel (G-90 galvanized or AZ-50 Galvalume coating) and aluminum, in panel widths of 12”, 16”, and 18”. Color options: 40+ standard colorways including Charcoal Gray, Gallery Blue, Colonial Red, Bronze, Forest Green, and custom colors via special order. All carry Kynar 500 or Hylar 5000 fluoropolymer paint systems with 40-year fade and chalk warranties. ARHT’s licensed crews are factory-trained on each manufacturer’s installation specifications.

How much does metal roofing cost in Maryland?

Standing seam metal roofing for a typical Montgomery County residential home (1,500–2,800 sq ft) costs $18,000–$38,000 installed. Steel systems (Galvalume or painted) are at the lower end; aluminum systems run 15–20% more due to material cost but offer superior corrosion resistance. Steep pitches (above 8:12), complex rooflines with multiple valleys and dormers, and homes requiring structural decking repairs add cost. Metal roofing costs 2.5–3x the price of GAF Timberline HDZ asphalt shingles upfront — but the lifetime cost calculation changes significantly when you account for 40–70 year lifespan versus 20–25 years for asphalt, eliminating 1–2 replacement cycles. ARHT provides free itemized written estimates for all Montgomery County zip codes — call 301-913-0650.

How long does metal roofing last in Maryland’s climate?

Properly installed concealed-fastener standing seam metal roofing lasts 40–70 years in Maryland’s climate — outperforming architectural asphalt shingles (20–25 years) by 2–3x. Maryland’s climate is actually favorable for metal roofing: freeze-thaw cycling that degrades asphalt granule bonds does not affect steel or aluminum panels; Nor’easter wind loads are shed by the panel geometry rather than absorbed; and summer UV exposure that bleaches asphalt shingles has minimal effect on Kynar 500-coated metal panels. Galvalume steel (AZ-50 coating) is rated for 60+ year structural performance in non-coastal environments. For Montgomery County zip codes 20850–20878, the primary longevity concern for metal is paint fade on south-facing exposures — covered by the 40-year paint warranty on all Fabral, McElroy, and Metal Sales systems ARHT installs.

Is metal roofing better than asphalt shingles for Maryland homes?

For homeowners planning to stay 15+ years, metal roofing consistently delivers better lifetime value in Maryland’s climate. Comparison vs GAF Timberline HDZ and CertainTeed Landmark Pro asphalt: (1) Lifespan: 40–70 years metal vs 20–25 years asphalt; (2) Ice dam performance: metal panel geometry sheds snow before ice dams form, while asphalt requires ice-and-water shield to mitigate dam infiltration; (3) Wind resistance: 140+ mph rated concealed-fastener systems vs 130 mph for Class 4 asphalt; (4) Energy: cool-roof coated metal reflects 70–80% of solar radiation vs 25–35% for standard asphalt; (5) Maintenance: virtually none for metal vs periodic inspection and spot repairs for asphalt. For homeowners selling within 10 years, asphalt at lower upfront cost is typically the better financial decision.

Does metal roofing require a permit in Montgomery County?

Yes — metal roofing installation requires a building permit from Montgomery County Department of Permitting Services (MCDPS), the same as any full roof replacement. ARHT (MHIC #137753) handles all permit applications as part of every project — no homeowner paperwork required. Metal roofing over an existing shingle roof (without tear-off) may also be permitted in some cases, but ARHT recommends full tear-off to inspect decking condition and ensure the substrate is sound before installing a 50-year system. Permits in zip codes 20850–20878 are typically approved within 1–3 business days. Unpermitted metal roofing installation can void the manufacturer warranty and create insurance complications.

What is a cool-roof coating on metal roofing and does it help in Maryland?

Cool-roof coatings are high-reflectance pigment systems applied to metal panels that reflect solar infrared radiation rather than absorbing it. Standard Kynar 500 painted metal panels have solar reflectance of 0.25–0.40 (25–40% solar reflection). Cool-roof coatings (ENERGY STAR® qualified) achieve 0.65–0.75 solar reflectance — reducing summer roof surface temperatures by 50–100°F versus dark asphalt. In Montgomery County zip codes 20850–20878, summer cooling savings of 15–25% on air conditioning loads are typical for homes with cool-roof metal versus dark asphalt. Available colorways include Light Stone, Bone White, Regal White, and Medium Bronze. Cool-roof coatings add approximately $0.50–$1.50 per sq ft to material cost and are most cost-effective on south and west-facing roof sections.

How does metal roofing handle ice dams and snow in Montgomery County winters?

Standing seam metal roofing performs significantly better than asphalt shingles in ice dam conditions for two reasons: (1) Snow shedding — the smooth metal panel surface releases snow before it accumulates enough depth to generate significant melt water; (2) No granule layer to degrade — ice dam water that contacts metal panels does not cause the same granule loss and mat exposure that damages asphalt. Ice dams can still form behind gutters on metal roofs if attic insulation and ventilation are inadequate, but water backing up under a concealed-fastener standing seam panel cannot find a penetration point to enter, unlike asphalt where water infiltrates at fastener holes and shingle laps. Snow guards are available and recommended on steeper pitch metal roofs in zip codes 20850–20878 to prevent sudden snow avalanche from upper-floor entries and walkways.

Is metal roofing loud in rain?

No — on a properly installed residential standing seam metal roof with solid decking beneath (plywood or OSB sheathing), rain noise is indistinguishable from asphalt shingles inside the home. The decking, attic air space, and ceiling insulation absorb sound effectively. The “loud in rain” perception comes from metal roofing on open-frame structures (pole barns, outbuildings) where there is no decking or attic buffer. Every residential metal roof ARHT installs in Montgomery County uses solid plywood or OSB decking plus underlayment, which completely eliminates the rain noise concern. On homes with cathedral ceilings and minimal attic buffer, a sound-deadening underlayment (such as Quiet-Batt or similar) can be specified at minimal added cost.

What warranty covers ARHT’s metal roofing installations?

Every ARHT metal roofing installation includes three warranty layers: (1) Manufacturer structural warranty — 50 years on Fabral, McElroy, and Metal Sales Galvalume steel systems; (2) Manufacturer paint warranty — 40 years against fade and chalk on Kynar 500/Hylar 5000 coated panels; (3) ARHT workmanship warranty — covers installation quality, seam integrity, and flashing details. Warranty registration is completed by ARHT with each manufacturer at project completion and documentation is delivered to the homeowner. Warranty service requests go directly to our team at 301-913-0650 — no manufacturer call centers. Available across all Montgomery County zip codes 20850–20878 and surrounding Maryland service areas.
