Asphalt roofing is created by joining several lengths of same-sized asphalt shingles together. Several materials are used in the creation of a metal roof including steel, aluminum and copper.
Homeowners can install a roof themselves to avoid costly professional contractor installation rates. Having an asphalt or metal roof installed professionally can add thousands of dollars to the ultimate price of a roof.
Having to install a roof on a steep angle or around complex architectural features can drive up the overall cost associated with an asphalt or a metal roof by up to an extra $1 to $3 per square foot.
The sources at costhelper.com claim that having a professional install an asphalt roof after removing and disposing of the existing roof will run the consumer between $1 and $4 per square foot. A profesionallly installed metal roof can cost between $3 and $18, depending on what type of metal will be used.
Removing and disposing of existing roofing can be a large underlying cost associated with a roof installation project. It can cost the consumer anywhere between $3 and $5 per square foot to remove and dispose of an existing roof.
