Calculate the price of your next EPDM roofing project

Input your roof size and RoofUs, our RoofBot, will automatically generate a quote with recommended products & prices

Step 1: Please enter your roof size in either metres or feet, and RoofBot will automatically add on 400mm as overhang

If you wish to cover a roof which is neither a square nor rectangle (such as an "L" shape), please calculate your EPDM in multiple parts by separating it into individual rectangles.





Your total area (excluding overhang and upstands): {{ area }}m²

Step 2: Please select your edge and trim type from the options below

We have a variety of edge trims available: please click on the corresponding corners to choose the edge trim which is most suitable for your specification.
