Disclaimer. Prices shown are estimates based on the information you entered and on Google satellite imagery and 3D height data, which may be months or years old. They are for planning and budgeting only and are not a quote, bid or contract. Your final price is set in a written proposal after a free on-site inspection, and it can change with the condition of your roof (rotted decking, extra layers of old roofing), pitch, access, permits, Florida Building Code and wind-zone requirements, and material prices and availability. Roof measurements are estimates and are checked on site before any material is ordered. Dumpster and travel charges are figured from the squares measured and the ZIP code you entered.
