What a Metal Roof Costs in Monticello, MN

Per square foot, installed

These are ranges for the Monticello and greater Twin Cities market as of 2026, for a complete installed roof — tear-off or recover, underlayment, ice barrier to code, flashing, trim and disposal. They are not material-only prices.

These are planning ranges, not an offer. Your actual price depends on decking condition, roof complexity, pitch, access, and the ventilation work your attic needs. We do not issue a firm price without getting on the roof. If a number here turns out to be wrong for your house, we will tell you before you sign, not after the tear-off.

Rough it out yourself

Enter your roof area — not your floor area. A single-story house with a 6:12 pitch has roughly 1.2 square feet of roof for every square foot of footprint; a steep 12:12 closer to 1.4.

What actually moves the number

Roof complexity, far more than roof size

The flat field of a roof goes down fast. The cost is in the edges: every valley, dormer, chimney, skylight, sidewall and pipe penetration needs flashed metal cut and fitted. Two houses of identical square footage can differ by 40% on this alone. It is why the St. Michael roofs we quote generally run above the Big Lake ones.

Decking condition

We do not know what is under your shingles until they come off. Soft or delaminated sheathing has to be replaced, and that is priced per sheet. A written scope should state the per-sheet rate up front so there is no negotiation happening while your roof is open.

Ventilation work

If the assessment finds an attic that is under-ventilated or leaking air, correcting it is part of the job rather than an upsell. Skipping it means installing a fifty-year roof over the exact condition that shortened the life of the last one.

Snow retention

Metal sheds snow in slabs. Where a roof plane discharges over a door, walkway, deck or driveway, engineered snow retention is a safety requirement rather than an accessory. Budget for it wherever people walk.

How to compare two bids properly

Ask both contractors to put these in writing. The cheaper bid frequently omits three of them.

• Panel profile and gauge — 24-gauge versus 26-gauge is a real difference in oil canning and denting.
• Clip type — floating or fixed. This governs whether the roof tolerates thermal movement.
• Ice barrier coverage — measured to 24″ inside the exterior wall line, per MN Residential Code R905.1.2. On deep eaves that is two courses.
• Underlayment type — synthetic versus felt, and what goes under the panel in the field.
• Decking replacement rate — priced per sheet, agreed before work starts.
• Who pulls the permit — and who books the final inspection.
• Warranty terms — separate the manufacturer's material warranty from the installer's workmanship warranty. They are not the same thing and only one of them is about the work.
