Stone-Coated Steel Roof Installation by ARCM Roofing
The look of traditional shingles, tile, or shake — with steel underneath. Protection engineered for 50 years or more.
5 Highlights on Stone-Coated Steel
Tile Looks. Shake Looks. Steel Strength.
Acrylic-bonded stone granules over galvanized steel — the granule finish that separates this system from painted metal shingles, with barrel tile and shake profiles no painted panel can match.
Class 4 Impact Resistance
Our panels withstand hail up to 2.5 inches in diameter, and many insurance carriers reward that rating with premium discounts.
Class A Fire Rating
Steel panels won't ignite from embers or wildfire exposure — a real consideration along Colorado's wildland-urban interface.
Wind Warranties Up to 120 MPH
Interlocking panel systems from DECRA and Unified Steel resist uplift far better than asphalt shingles.
Lightweight Construction
At roughly 1.5 pounds per square foot, stone-coated steel weighs 75% less than concrete tile, so your framing carries less load.
50-Year Limited Warranties
Manufacturers back these roofs for decades, and the granular stone coating keeps its color without cracking, curling, or rotting.
A roof built to outlast the mortgage.
Why Choose Us
We Install These Systems Every Week
We're not a general contractor who dabbles in metal. Our installers hold manufacturer certifications from DECRA and Westlake Royal Roofing, which qualifies your project for extended warranty coverage non-certified contractors can't offer.
Our project managers photograph each stage of the installation, from deck inspection to ridge cap, so you see exactly what we built. Estimates itemize panels, underlayment, battens, flashing, fasteners, and labor — no vague line items.
Our 10-year workmanship warranty stands separate from the manufacturer's material warranty, we carry full liability and workers' compensation on every crew member, and magnetic sweeps run daily with all tear-off debris hauled away.
Our reviews reflect completed stone-coated steel projects, not just asphalt work.
When It Makes Sense
Signs Stone-Coated Steel Is the Right Upgrade
Repeated Hail Damage Claims
If you've filed two or more insurance claims for hail-bruised asphalt shingles, you're stuck in a replacement cycle. Class 4 stone-coated steel panels shrug off impacts that fracture fiberglass mats and dislodge granules on conventional shingles.
Curling, Cupping, or Granule Loss
Asphalt shingles nearing end of life curl at the edges, cup in the field, and shed granules into your gutters. Once the fiberglass mat is exposed, UV degradation accelerates and leaks follow. Steel panels never curl.
Cracked or Slipping Tile
Concrete and clay tiles crack under foot traffic and slip when fasteners corrode. Stone-coated steel replicates the barrel tile profile at a fraction of the weight, and you keep the Mediterranean look without the structural strain.
Wind Uplift and Blow-Offs
Missing shingles after every storm point to failed sealant strips or inadequate nailing patterns. Interlocking stone-coated panels fasten horizontally into battens or directly to the deck, creating a continuous mechanical connection that resists uplift at every edge.
Rising Cooling Costs
Dark asphalt roofs absorb heat and push attic temperatures past 150 degrees in summer. Stone-coated steel reflects solar radiation, and battened installations create an air gap that ventilates heat away from the deck.
Stuck in the hail-claim cycle? Break it with Class 4.
How We Work
Our Eight-Step Installation Process
01
Inspection and Measurement
We inspect your existing roof, measure every plane, and check the decking for soft spots, rot, and fastener pull-through.
02
Written Proposal
You receive an itemized estimate with panel profiles, color samples, and warranty documents. We answer every question before you sign.
03
Tear-Off or Overlay Assessment
We remove old shingles down to the deck in most cases. Where code allows, stone-coated steel's light weight permits installation over one existing shingle layer.
04
Deck Repair and Underlayment
We replace damaged sheathing, then install synthetic underlayment and ice and water shield in valleys and at eaves.
05
Batten Installation
For batten systems, we fasten treated wood or steel battens on precise spacing to match the panel course layout.
06
Panel Installation
Crews interlock each panel and fasten it into the batten or deck, working from eave to ridge.
07
Flashing and Detail Work
We flash chimneys, skylights, and sidewalls, seal every penetration, and install matching ridge caps, hip caps, and trim.
08
Final Walkthrough
Our project manager inspects the finished roof with you, registers your warranty, and hands over all documentation.
Refined across hundreds of projects — firm schedule before work begins.

FAQs
FAQs About Stone-Coated Steel Installation
›What is stone-coated steel roof installation?
Stone-coated steel roof installation is the process of fastening interlocking steel panels, coated with acrylic-bonded stone granules, onto your roof deck or batten grid. The panels mimic shingles, shake, or tile while delivering steel's durability.
›How long does installation take?
Most residential projects take three to five days. Complex roofs with multiple valleys, dormers, or steep pitches may run a week. We give you a firm schedule before work begins.
›How much does a stone-coated steel roof cost?
Expect $9 to $16 per square foot installed, depending on profile, roof complexity, and tear-off requirements. That's two to three times the cost of asphalt, but the roof lasts three to four times longer.
›Can you install stone-coated steel over existing shingles?
Yes, in many cases. The panels weigh about 1.5 pounds per square foot, so local code often permits overlay installation on a single shingle layer. We verify code compliance and deck condition first.
›Does a stone-coated steel roof lower insurance premiums?
Many carriers discount premiums for Class 4 impact-rated roofs. Discounts vary by state and insurer, and we provide the product documentation your agent needs.
›Why do panels need battens?
Battens create the fastening grid for horizontal panel courses and add an air gap that ventilates heat away from the deck. Some profiles fasten directly to the deck instead. We recommend the system that fits your roof and climate.
›When should I schedule installation?
Spring and fall offer ideal conditions, but our crews install stone-coated steel year-round. Call ARCM Roofing today for a free estimate.
