Roof Cost Calculator for Boulder, CO
This calculator turns four quick answers about your house into a planning range for a new pitched roof in Boulder, CO. It uses 2026 Colorado installed prices and works the same for any home in Boulder County. Nothing you enter is saved or sent anywhere, and the result is a starting point, not a price.
How to Use This Tool
Before you start: the tool estimates how much roof sits over your house, then multiplies that area by a per-square-foot price. It divides your living space by the number of stories to get a footprint, adds a factor for how steep the roof is, and adds 10% for the eaves that hang past the walls. The area is rounded to the nearest 10 sq ft.
For shingles, the range runs from the "Colorado 3-tab shingles, per sq ft" row (about $5.10) to the "Colorado premium shingles, per sq ft" row (about $6.95). For metal, it starts at the low end of the "Colorado exposed-fastener metal, per sq ft" row (about $7.50) and tops out at aluminum standing seam (about $15.45), with the "Colorado standing-seam metal, per sq ft" row in between. All figures come from RoofObservations (2026) and include tear-off. Slate, tile and flat roofs fall outside this tool and need a roofer's own quote.
What to Do With the Result
Keep the range handy when estimates arrive. If a written price sits far outside it, ask the roofer to walk you through the lines that differ, such as extra layers, decking boards or steep sections. To see whether the roof needs replacing at all, take the repair-or-replace quiz, or read the cost guide for tile and slate figures. For a real figure, fill in the request form and a single independent roofer from the area will get in touch.
