Roof size is the measured roof surface, which is larger than your home's floor area because of pitch and overhangs. One “square” equals 100 sq ft of roof surface. If you are not sure, start with your home's footprint plus roughly a third — an inspection measures it exactly.

Disclaimer: This calculator provides a rough educational range for planning purposes only, using general market rates. It is not an offer, quote, or guarantee of price for any property. Roofing prices change with material and labor costs, and hidden conditions found during tear-off can change a final price. Always rely on a written, property-specific estimate from a licensed contractor before making a decision.

Compare scope, not just totals
Two estimates can look similar while covering very different work.
Measurements, waste factors, product lines, and accessories may differ.
One estimate may include flashing, ventilation, or tear-off that another omits.
Decking allowances and hidden-condition language can change the final price.
Warranty coverage and manufacturer-system requirements affect scope.
Steep slopes, height, staging, and access can materially change labor.
A property-specific written estimate is the only meaningful way to price the work.
Calculator questions
Roof cost questions, answered honestly.
The calculator gives you a planning range. These answers explain what it can and cannot tell you — and how to get a real number.
How much does a new roof cost in Maryland?
It depends on measured roof size, material, pitch, complexity, and tear-off. Enter those details in the calculator on this page and it will turn them into a broad planning range in seconds. The only meaningful number for your home is a written, property-specific estimate after an inspection.
Is the roof cost calculator a quote?
No. The calculator returns a rough educational range built from general market rates per square. It is not an offer, a quote, or any contractor's pricing, and it does not include items like decking replacement or structural repairs. An inspection and a written estimate are required for real pricing.
What is a roofing square?
A square is a standard roofing measurement equal to 100 square feet of roof surface. A 1,700 sq ft roof is 17 squares. Roof surface is larger than a home's floor area because pitch and overhangs add area.
Why do roof estimates for the same home vary so much?
Estimates vary because contractors may measure differently, include different product lines, and make different assumptions about tear-off, decking, flashing, ventilation, disposal, and warranty scope. Comparing scope line by line matters more than comparing totals alone.
How do I get an exact price for my roof?
Schedule a free roof inspection. A specialist measures the roof, checks decking and flashing conditions that are visible, documents the findings, and provides property-specific pricing and options with no obligation.
