Why Metal

What metal buys you over asphalt

2-3x the lifespan

Asphalt runs 15-25 years in the DMV's freeze-thaw cycles. Properly installed standing seam runs 40-70. You buy one roof instead of three.

Storm resilience

Metal sheds hail that bruises asphalt and holds seam integrity in winds that strip shingles. Insurance carriers know it — some offer premium credits for impact-rated metal roofs.

Energy savings

Reflective Kynar finishes cut summer attic temperatures and cooling bills — a real number in Maryland's humid summers — and many panels qualify as cool roofs.

Systems We Install

Standing seam vs. screw-down

Standing seam

Concealed-fastener panels with raised, interlocking seams — no exposed screws to back out and leak. The premium residential choice, with clean lines and the longest service life. Available in snap-lock and mechanically-seamed profiles.

Exposed-fastener (screw-down)

Ribbed panels fastened through the face — a lower-cost metal option well suited to outbuildings, barns, and some low-slope sections, installed with proper gasketed fasteners and a fastener-replacement plan.

Substrate done right

Whichever panel, the roof is only as good as what's under it. We typically tear off to inspect and repair decking, lay a high-temp underlayment, and detail every valley, penetration, and transition before a panel goes down.

Common Questions

Straight answers

Is a metal roof louder in rain?

No — over solid decking and underlayment, a metal roof is no louder than asphalt. The rain-on-a-barn sound comes from open-frame structures.

Can you install metal over my existing shingles?

Sometimes, but we usually recommend tear-off so decking issues get found and fixed — that's what protects the 40-70 year lifespan.

Does metal cost more?

Upfront, yes — typically 2-3x asphalt. Over the roof's life it's usually cheaper per year, and it adds resale value.

Standing seam or screw-down?

Standing seam hides its fasteners and is the premium residential choice; exposed-fastener screw-down panels cost less and suit outbuildings and some low-slope sections. We recommend based on your roof, not our margin.
