Cost guide
What a metal roof costs in Maine
Standing seam in Maine runs roughly $9 to $16 per square foot installed, and a typical whole-house project lands around $15,000 to $28,000 (Maine cost data). National publishers put standing seam at $7 to $30 per square foot (Angi) and $9 to $16 (HomeGuide). That is the honest answer up front; the rest of this page is what moves a quote inside those bands.
Cost by system
| System | Maine | National | Worth knowing |
|---|---|---|---|
| Standing seam (concealed fastener) | $9 to $16 per sq ft installed | $7 to $30 (Angi); $9 to $16 (HomeGuide) | The snow-country system. Panels lock over hidden clips; nothing penetrates the surface. |
| Exposed-fastener panels (screw-down) | Below standing seam; see national band | $3.50 to $15 (Angi); $5 to $12 (HomeGuide) | The budget option. Gasketed screws through the panel face need periodic re-tightening. |
| Asphalt shingles, for comparison | $7,500 to $14,000 typical house (architectural) | $3 to $5 per sq ft installed | The 15 to 30 year cycle a metal roof replaces. |

Whole-house totals
What does the whole project cost? For a typical Maine house, published data puts a standing seam replacement at about $15,000 to $28,000, and a 1,500 square foot roof at $13,500 to $24,000 (Maine data). Nationally, Angi reports standing seam projects from $9,400 to $32,600 with a $19,000 average (Angi), and HomeGuide reports $13,500 to $40,000 installed (HomeGuide). Large, complex, or coastal-aluminum roofs land above the middle of those ranges.
Against that, a Maine architectural-shingle replacement on a typical house runs about $7,500 to $14,000 (same dataset). The metal premium is real. What it buys is the end of the shingle cycle: metal roofs are documented at 40 to 70 years of service against 15 to 30 for asphalt (Bob Vila), which is one roof instead of two or three over the same decades.
What moves a Maine quote
-
Roof size and shape
Cost scales with area, but complexity scales faster. Dormers, valleys, and chimneys mean more flashing hours per square foot than a plain gable.
-
Tear-off vs overlay
Removing the old shingles adds labor and disposal. Some Maine metal roofs install over one shingle layer where the structure and code allow; the estimate should say which and why.
-
Material and gauge
Aluminum for coastal homes prices differently than Galvalume steel, and heavier gauge costs more. Within 1,500 feet of saltwater the material choice is a warranty question, not a taste question.
-
Snow retention and trim detail
Snow guards over entries, ice-and-water membrane at the eaves, and quality trim are where snow-country installs differ from catalog pricing.
-
Access and season
Steep pitches, tall eaves, and tight sites slow the crew. Scheduling shoulder-season work can matter more than haggling.
How to compare quotes without getting burned
Maine law is on your side here: any home construction contract over $3,000 must be written and signed, with the down payment capped at one third of the price (10 M.R.S. 1487). Insist on itemized estimates that name the panel system, the metal and gauge, underlayment, tear-off or overlay, trim, and snow retention. Two quotes that both say "metal roof" can be two different roofs; the paperwork is how you find out. The Maine Metal Roofing Guide carries the full owner checklist, and the replacement page covers the tear-off decision in detail.
