On 60 Interlock® aluminum roofs we contracted in New England in 2025 and 2026, the middle half came to $31,900 to $58,300, a median of $43,900. By roof area that is $16.44 to $20.06 per square foot ($1,644 to $2,006 per roofing square). These figures are a rough guide only.

What moves the price on a New England roof
Roof area
The biggest single factor: the more square feet of roof, the more material and labor.
Pitch, dormers and chimneys
Steep Capes and Victorians, dormers, turrets, valleys, skylights and chimneys each add flashing and time. A plain gable costs less per square foot than a cut-up roof. Every Interlock profile needs a minimum 3/12 slope.
What comes off
Cedar shingles and shakes, concrete tile and natural slate always come off. Many New England houses have two or more layers of asphalt, or asphalt over old cedar; those come off too. A single layer of asphalt can be roofed over only if the inspection finds it suitable. Deck repairs the inspection finds go into the written price.
Height and staging
Triple-deckers and other tall houses, tight city lots and shared driveways need more staging, more setup and more care moving material, and that shows up in the price.
Coastal and exposed sites
Shoreline and hilltop houses take the full force of nor'easter wind and salt air, and island jobs add transport and logistics. We plan the details for the exposure at your consultation.
Historic districts and town permits
In a local historic district, the historic commission's review can affect the profile and color you choose and the timing; check with the commission before you sign. Building permit requirements and fees are set by each town.
Winter scheduling
Snow, ice and short days affect when a roof can be opened up and how fast it goes. We talk through timing with you at the consultation.
Profile and options
Slate, Cedar Shingle, Shake, Mediterranean Tile, Standing Seam and solid copper are priced differently. The Class A Fire Rated Available assembly (two layers of GAF VersaShield® over 15/32-inch plywood), ice-and-water membrane, snow guards and gutters are line items.
What the price includes
- The Interlock® aluminum roof, made in North America by Interlock Roofing, installed by our own company, Interlock Metal Roofing (New England) Inc., in business since 1999.
- The Guardian Lifetime Limited Material Warranty from the manufacturer: material and finish, for as long as the original purchaser owns the home, transferable once. Workmanship is not part of it.
- Our 10 Year Limited Labor Warranty on the installation (see the labor warranty page for its terms).
- Wind resistance warranted to 120 mph installed to manufacturer specification.
- A written price after your roof consultation: what the inspection finds goes into it before you sign.
Comparing it with steel and asphalt
Aluminum costs more than steel or asphalt up front. The fair comparison is over the years you'll own the home: an asphalt roof lasts about 20 years on published averages and is then torn off and replaced, while an Interlock roof is built to be the last one. Get every quote in writing and compare them over the same period.
If you'd like to spread the cost, financing is available from 9.99% APR on approved credit; the terms are on our roof financing page.

Do these prices include sales tax?
They are contract totals as signed, and our job book doesn't record taxes separately. Your written price after the roof consultation shows exactly what is included.
Why is aluminum more expensive than steel?
Aluminum costs more as a metal, and an Interlock roof uses interlocking panels with concealed fasteners rather than exposed screws. What you get for it is a roof that doesn't rust, which matters on the coast, and a Guardian Lifetime Limited Material Warranty.
