About Our Metal Roofing Installation & Repair Service
A properly installed metal roof is the longest-lasting roof most New Jersey homes will ever have — 40 to 60 years of service with almost no maintenance. We install standing-seam and metal shingle systems, and repair existing metal roofs, with the concealed-fastener detailing and thermal-movement allowances that separate a metal roof that lasts from one that leaks at year fifteen.
Why Homeowners Choose Metal
Metal roofing has moved from a niche, agricultural product to a mainstream premium residential choice in New Jersey over the last decade. The appeal is straightforward: a standing-seam metal roof installed correctly will outlast two or even three asphalt roofs, shed snow and ice instead of holding it, and never need the granule-loss-and-curl replacement cycle that defines asphalt. For homeowners planning to stay in a home long-term, the lifecycle math often favors metal despite the higher upfront cost.
Standing-Seam vs. Metal Shingle
There are two main residential metal systems, and they are not interchangeable. Standing-seam uses long vertical panels that lock together along raised ribs, with the fasteners concealed beneath the seam — no screw ever penetrates the weather surface. Metal shingles (including stone-coated steel) mimic the look of asphalt, slate, or shake while delivering metal's longevity, and install in a more traditional overlapping pattern.
- Standing-seam: cleanest look, concealed fasteners, the premium long-term choice — best for most NJ residences.
- Stone-coated steel: metal performance with a traditional shingle or tile appearance, often used where HOA aesthetics matter.
- Exposed-fastener panels: lowest cost, appropriate for outbuildings and garages, but every exposed screw is a future maintenance point.
The Detail That Makes Metal Last: Thermal Movement
Metal expands and contracts significantly with temperature — a 30-foot panel can change length by a quarter inch between a cold morning and a hot afternoon. The single most common reason metal roofs fail early is rigid fastening that doesn't allow this movement, which elongates fastener holes and eventually admits water. Our standing-seam installs attach panels with concealed clips that let the metal float, so the roof handles New Jersey's freeze-thaw cycling without stressing a single penetration.
Snow & Ice Performance in NJ
Metal sheds snow rather than holding it, which dramatically reduces ice-dam risk compared to asphalt. The trade-off is that accumulated snow can release in large sheets, so we install snow guards above entryways, walkways, and anywhere a sudden slide could damage gutters, landscaping, or a person below. It's a small detail that prevents a real hazard.
Repairing an Existing Metal Roof
Not every metal roof needs replacement. We repair existing metal roofs by replacing aged fastener gaskets on exposed-fastener systems, re-sealing penetrations and transitions, addressing rust at cut edges before it spreads, and correcting failed flashing at walls and chimneys. If your metal roof is leaking, we diagnose whether it's a repairable detail failure or genuine end-of-life before recommending anything.

Metal Roofing Installation & Repair — Common Questions
How much does a metal roof cost in New Jersey?
Installed standing-seam metal in NJ generally runs $9–$16 per square foot — roughly 2–3× the cost of architectural asphalt. Stone-coated steel and exposed-fastener panels fall at the lower end; premium standing-seam with upgraded coatings at the higher end. Use our roof cost calculator for a size-based estimate, then we'll give you a firm written quote after an inspection.
How long does a metal roof last?
A properly installed standing-seam metal roof lasts 40–60 years in NJ's climate, often outliving the homeowner's tenure in the house. The coating (the painted finish) typically carries a 30–40 year warranty against fade and chalk, while the panel itself lasts far longer. This is the core reason metal's higher upfront cost can be the lower lifecycle cost.
Is a metal roof noisy when it rains?
No — this is the most common metal roof myth. A residential metal roof installed over a solid deck with synthetic underlayment is no louder in rain than asphalt. The 'noisy metal roof' image comes from barns and sheds where metal is installed over open purlins with no deck or insulation beneath it.
Can you install metal roofing over my existing shingles?
In some cases metal can go over a single layer of asphalt, but we almost always recommend tear-off. Going over old shingles hides the deck condition, can telegraph unevenness through the metal, and complicates the underlayment and ventilation detailing that metal needs to perform. We'll tell you honestly whether your roof is a candidate for an overlay.
