Roof cost by material
Material is the biggest single lever on a roofing price, and it moves labor as well as material — heavier and more fragile systems install more slowly on the same roof.
Every page below runs the same central pricing engine and the same published assumptions, so the numbers are comparable across materials rather than collected from unrelated sources. Regional adjustment is applied to the labor component only, because material is not priced by a regional index. Each assumption carries its own verification status in the source registry, and the calculation is described step by step in the methodology.
Asphalt shingles
The most widely installed residential system in the United States. Three-tab is the entry point; architectural (laminated) shingles are thicker, carry longer manufacturer warranties and are what most quotes now default to. Labor is the fastest of any pitched system, which is why the installed price sits at the bottom of the range.
Metal
Exposed-fastener panels and concealed-fastener standing seam are two different projects. Panels compete with premium shingles on price; standing seam costs more because the panels are formed and seamed on site and the flashing detail is unforgiving. Both are light enough for typical framing.
Tile and slate
Heavy systems. The material is expensive, the installation is slow, and the structure may need review before the old roof comes off. Where these are the regional norm, local crews are practiced and the labor premium narrows.
Wood
Cedar shake is a specialty install with a shrinking pool of experienced crews, and local fire codes can restrict it. Price it as a craft trade, not a commodity.
Low-slope and flat membranes
A flat roof is not a cheap roof — it is a different one. Modified bitumen, TPO, EPDM and PVC are priced per square of membrane plus edge detail, drains and insulation, and the seam method drives the labor line.

An average is not your roof. Run your own size, pitch and complexity through the calculator, or take a quote you already have to the checker.
Pricing assumptions require source verification
The unit costs, regional index and adjustment multipliers behind this estimate are currently labeled DEMO / PLACEHOLDER. They exist so the calculation engine, methodology and source registry can be reviewed end to end. They are not published market prices, and every value is editable in the pricing database once verified data is loaded.
