To calculate the total cost of a p shapped roof you need to order 3 sections.
1. The larger section in either a victorian or edwardian style.
2. a made to measure leanto roof for the small section (order the gutter side size)
3. A valley section as below.

Example 1. Above
Victorian 3 Facet 3.75m x 4.0m = £1457.00
Leanto roof 2.0m x 2.25m = £550.00
Plus Valley Bar = £351.31
Total Price = £2358.32
Price excludes gable infill panel.

Example 2 Above
This roof also has a hip bar on the lean to section.
Victorian 3 Facet 3.75m x 4.0m = £1457.00
Leanto roof 2.0m x 2.25m = £550.00
Plus Valley Bar = £351.31
Plus a hip bar = £225.00
Total Price = £2580.39
