How roofing jobs are priced
It's not just size. The price of a new roof is based on a number of factors.
The type of roofing materials you choose and the type of warranty you get, play a big role.
The slope of the roof can make a big difference. According to Angie's List, it costs more to replace a very steep roof because it requires greater staging and safety equipment, and in some cases, different materials.
How many layers of shingles are there on the roof that need to be removed? The price is typically based on time and disposal charges.
And of course, the price will go up if any of the plywood needs to be replaced.
When preparing an estimate, the contractor will also look at obstacles, such as chimneys, skylights and box vents. Limited access to the roof can also be a factor.
Angie's List says it's not necessary to replace the soffits or gutters when replacing your roof. The contractor just needs to be careful not to damage the gutters when they're removed.
Keep in Mind: No reputable roofer will give you a quote without coming to your house, examining the roof and going inside the attic.
