Measure and Estimate the Space

After all the necessary materials have been collected, measure the roof and the area where work will be done. Measure the dimensions, lengths and widths of the roof and roofing elements, so you know what you are dealing with. Make sure that you double check your calculations.

Budget and Cost Analysis

You’ll need to complete a budget and cost analysis to understand and manage costs. When preparing the budget, be sure to factor in materials, labor, installation, and any additional fees or taxes.
