Calculate Roof Installation Cost based on your roof size, slope, roofing material, & building height. Estimates costs for Asphalt, Metal and Flat roofing. This calculator will help estimate total roof installation cost for new or re-roof projects, by a professional roofing contractor, & includes all materials, labor, & misc. costs of new roof install, such as dump fees, building permits, profit & overhead.
To estimate roof replacement cost, you need to get ground measurements of your house (if your roof has overhangs, ADD [overhang width * 2] to both length and width), roof slope (pitch), roof complexity, height of the building, number of chimneys / skylights, length of ridge vent (if any), number of roof layers to be removed (tear-off) and a roofing material you are estimating.
Roofing prices are approximate, and will vary depending on your geographic location, and current roofing materials costs.
See how we came up with the prices for this roofing calculator in our roof installation prices guide.
If you do not know your roof slope, use our Roof Pitch Calculator to measure / calculate / convert the slope.
Factors affecting Roof Prices Calculation:
Do note that roofing materials cost, used in this calculating roof installation prices, fluctuates greatly, depending in large on the cost of crude oil, as well as other factors, such as season, region of the country, and in part by natural disasters such as hurricanes, etc. We try to keep the calculation formula in sync with roofing materials costs.
Additionally, it is impossible to have a exact roof estimated cost, as there are many variables that can affect the final number. These variable include local conditions and complexity of your roof, local economic conditions, and costs of liability and worker’s compensation insurance for the contractor, waste dumping costs, labor cost of the contractor doing the work, as well as overhead and profits. The calculated roofing prices are ONLY approximate figures, to let homeowners have a better understanding of what it would cost the to replace their roof.
