Most roofing jobs require professional installation, so you'll need to factor in labor costs in addition to material costs. Did you know? The average size of residential roofs in the U.S. The US is approximately 1,700 square feet or 17 square feet, although there are many larger homes with roofs that can exceed 2,000 square feet. In fact, larger residential properties with garages can easily exceed 3,000 m2. Did you know? Proper tile alignment is not really a concern with architectural or dimensional shingles that have a more random pattern compared to 3-tab uniform strip shingles.
Did you know? A portion of the increase in the total cost of installing premium shingles must be reflected and offset by a longer labor warranty (the promise of quality installation) provided with the installation. A comprehensive 10-year labor warranty is what you should expect, at a minimum, at this price. From the Northeast, the Massachusetts area and I have been looking for quotes to re-roof an 840 square foot total roof that I rounded up to 900 square feet to be generous. Therefore, a 3,000 square foot single-story home can have a fairly large roof, depending on the slope of the roof and whether there is a garage that also needs a new roof.
Some roofs may also have peaks, dormers, and valleys that can add square feet to the roof topology. Renting a dumpster can be more expensive upfront, but if you have a complete roof replacement with several trucks loaded with shingles to dispose of, your roofer may charge more for multiple trips to the junkyard. To calculate how much roofing material you need, you'll need to know the square feet of your roof, along with its pitch. I live in Fort Washington, Maryland (near Washington, DC), and I have a 14-square straight roof replacement (1 layer of 20-year-old 3-tab shingles).
The price per square can often be higher when a roof has many complex features, such as end walls, multiple chimneys, and skylights or dormers. However, an 11-square roof is a relatively small job, so the price per square will generally be higher than the average. We knew the roof was old and would need some repairs, but they charge us almost double the estimate. All things being equal, professional roofers in expensive coastal areas (such as homes in Boston, New York, Washington DC, Miami, Los Angeles, San Francisco, Portland OR, and Seattle) will charge more for their services compared to roofing contractors in the South, Midwest, or rural areas.
This is for approximately 35 tile squares in a two-story house with a hipped roof and includes the cost of installation and a dumpster. Based on the details you shared, it looks like you have a single-story ranch with a fairly simple roof (inferred from the square feet of the floor plan vs.
