Roofing Calculators
Estimate materials, geometry, and costs for roofing projects. These 9 calculators cover shingle bundles, rafter length, roof pitch, slope conversion, cost estimation, and gutter installation. Use them to plan material orders, verify contractor quotes, and compare roofing scenarios before you commit to a project.
-
Roofing Calculator
Estimate roof area, roofing squares, material packages, and waste from footprint dimensions or known area with editable pitch and coverage.
-
Roof Estimate Calculator
Estimate roof area, roofing squares, waste, and total project cost for any material type with transparent line item breakdown.
-
Roof Replacement Cost Calculator
Estimate total roof replacement cost by size, pitch, material, tear-off, and repairs with an itemized low, typical, and high range.
-
Metal Roof Cost Calculator
Estimate adjusted roof area, material, labor, tear-off, accessories, and total installed cost for a metal roof.
-
Shingle Calculator
Estimate bundles, roofing squares, waste, starter strip, and ridge cap for asphalt shingle roofs.
-
Rafter Calculator
Calculate rafter length, roof angle, overhang cut length, and total lumber needed for any pitch.
-
Roof Pitch Calculator
Calculate roof pitch in degrees and ratio from rise and run measurements.
-
Rise Over Run Calculator
Convert rise and run measurements to slope percentage, angle, and pitch ratio.
-
Gutter Installation Cost Calculator
Estimate gutter installation cost by linear footage, material type, and story height.
When to use these calculators
- You're estimating roof area and material quantities before ordering shingles, panels, or tiles.
- You're planning a roof replacement and want a transparent cost estimate before calling contractors.
- You're estimating the full installed cost of a metal roof before requesting bids.
- You're ordering shingles and need to know how many bundles to buy.
- You're comparing material estimates before hiring a roofing contractor.
- You're planning a new roof and need rafter length before ordering lumber.
- You're building a shed, porch, or garage roof and want the rafter geometry for a given pitch.
- You're checking a contractor's lumber quote against your own measurements.
- You need to calculate roof pitch from rise and run measurements for framing or material selection.
- You're estimating gutter installation cost by linear footage before scheduling a replacement.
