⚠️ That's a very large roof. Please double-check your measurements are in
metres, not millimetres — e.g. a 3.9 m roof is entered as “3.9”, not “3900”.
Enter the four outside measurements of your L-shaped roof, matching the numbers on the diagram. The two inner step measurements (2 & 3) are worked out for you. Don't add anything for overhangs — we add 200mm to every side automatically.

Rubber sheet join
The two rubber sheets will need to be joined along the orange line shown on the diagram — we include the seam tape for this in your quote. Choose whichever direction suits your roof.
Covering an "L" shape? Choose "L-shaped" above and enter the outside
measurements — we'll work out the inner steps and where the rubber sheets will need to be joined.
Step 2: Click each edge of your roof and choose its type
Click each numbered edge of your L-shaped roof and choose what it meets (wall, gutter, kerb…). The join between the two sections is handled automatically — you don't need to mark it.
