Multiply the square feet by the cost per square foot of the selected material. Add in the additional costs associated with the slope or complexity of your roof. The height and accessibility of the roof influence the price of roof replacement. Installing a new roof in a two-story house will take longer than installing a single-story roof, since it takes longer to place the materials for the roof.
It also means that roofers must take extra precautions to ensure they complete the job safely. With a number in hand, you're ready to calculate how much your new Texas-sized roof is going to cost. A variety of factors determine the cost when you have to change your old roof; one of the main influencing factors is the difficulty of designing your roof. The area calculator can be used to calculate the area in a variety of simple ways that, together, can comprise the roof area.
Roofing contractors usually estimate the cost of replacing a roof based on the square footage of the roof. Taking into account the slope and a measurement of the horizontal area, multiply the horizontal area by a correction factor corresponding to the slope, shown in the table below, to determine the actual roof area to be used in the roofing materials calculator. Another factor that will influence the cost of your new roof is whether you are going to replace all or only part of it. In cases where a roof has a complex shape, as in the image on the right, measuring the dimensions and areas of each part of the roof to calculate the total area will result in a more accurate measurement of the area. A larger roof not only means that more raw materials are needed, but it also means higher labor costs due to the additional time needed for installation.
The good news is that replacing moldings and ceilings is a project you can do yourself, so replacing them yourself is an easy way to save on the cost of replacing the roof. If you cannot contact any contractor, calculate the cost of materials (for example, if you go to the nearest construction store) and multiply this price by 2.5.The roof calculator allows you to determine the area of the gable roof or shed of your house and estimate its cost accurately. Next, we calculated the square footage of the roof using a roof pitch multiplier of 1.12 for one- and two-story homes, along with the sample costs of 3-ply asphalt shingles (low-end), mid-range metal shingles, and high-end slate shingles.
