First, measure the length and width of each plane of the roof, including dormers or other protrusions. Then measure the length of each plane. Then multiply the length by the width of each plane to get the square footage of each roof section. Roof replacement costs can vary significantly by region due to differences in labor rates, material availability, and local building codes. The good news is that replacing the fascia and the ceiling is a project you can do yourself, so replacing them yourself is an easy way to save on the cost of replacing the roof.
In addition, you can use the roof cost calculator at the top of this page to get a better estimate of what it will cost you to replace the roof. Depending on the material, you may not have to remove the existing roof, which can save you quite a bit of money on installation costs.
Roofing
contractors usually estimate the cost of replacing a roof based on the square footage of the roof. Roof Maxx offers a free tool that calculates the cost of replacing your roof and also shows how much you could save with roof rejuvenation, which extends the lifespan of asphalt shingles up to 15 years and can cost up to 80% less than the replacement.Metal roofs also take up to three times longer to install than asphalt shingles, increasing the total cost of roof installation. Next, we calculated the square footage of the roof using a roof pitch multiplier of 1.12 for one- or two-story homes, along with a sample of the costs of 3-ply (low-end) asphalt roof tiles, mid-range metal tiles, and high-end slate tiles. Taking into account the slope and horizontal area, multiply the horizontal area by a correction factor corresponding to the slope, as shown in the table below, to determine the actual roof area to be used in the roofing materials calculator. The cost may be higher for larger homes, homes with complex roofs, or when more expensive materials are installed.
Keep in mind that while this will save you money now, you'll eventually have to remove those layers, so subsequent roof replacements will cost more. Most roofing contractors will provide you with a quote with the cost per square of materials, where one square of roof equals 100 square feet. Roof Maxx rejuvenates existing roof tiles and extends their lifespan up to 15 years without the need to replace them expensive. Roof Maxx rejuvenates asphalt shingles and extends their lifespan up to 15 years, while costing up to 80% less than a traditional roof replacement.
