How much do roofers ask for upfront?

It's best to get at least three quotes from reputable roofers in your area. They will come out to your house and inspect the roof to see what needs to be done, then give you an estimate for the job. The installation of a new roof usually includes removing the old roofing material, installing insulation and underlayment, installing the new roofing material, and then sealing the edges. The price will vary depending on the materials used (metal vs. asphalt shingles vs. tiles) and on the size and complexity of the job. Hope that helps!
