If any mods are around could I get a sticky on this please?
Many people come here asking for estimates on their projects, unfortunately price can vary greatly due to a number of factors which make it almost impossible to do over the internet. Your best course of action is to get at least three estimates from local, reputable, insured roofing contractors and compare. If you post a full set of quality pictures, list your city/state and a quick synapsis of your project, you may get lucky and have a Roofing.com member shoot you a very ball park price for your area. However keep in mind that the only price that will matter in the end is the one on the contract you sign.
