Metal roofing is some of the most durable types of roofing available. A metal roof can last for several generations before showing signs of wear. Metal roofing is available in shingles or standing-seam form. An asphalt roof is made up of many similar-sized asphalt shingles. Asphalt roofing is also durable but not as durable as metal roofing. However, a well-maintained asphalt roof can still last for a few decades before it needs replacing.
Installing a steel roof atop a covered patio can run between $3 and $10 a square foot. An aluminum roof can cost anywhere between $7 and $15 per square foot. The cost of professionally installing a metal roof made up of metal sheets or shingles will cost in the lower range of the above-mentioned figures. Standing seam roofing costs fall in the higher range of these figures. Asphalt shingles are much cheaper than metal roofing. Professionally installing an asphalt roof can cost between $1 and $4 per square foot.
Other than materials and labor costs, several additional costs may accompany a roofing installation project. Removing and disposing of a preexisting covered patio roofing system can cost up to $5 per square foot of roofing removed. In some cases, a roof requires extra support to hold up the weight of heavy roofing like steel roofing. Replacing or reinforcing the frame around a covered patio to accommodate a new roof can cost several hundred if not thousand dollars
