Roofing installation in the UK typically runs between £5,000 and £8,500.
In 2023, the roofing activities market is projected to be worth £5.5bn.
Simply multiply the length of your roof by the height of your roof slope, then multiply that number by two to get your roof area. If you exclude the area that is not tiled, such as around a chimney, this should give you the entire area of your roof.
Most British homes have roof pitches between 40 and 50 degrees, with the maximum being 70 degrees (anything higher is technically a wall). As it is up to the designer, different houses from different eras may have vastly varying roof pitches. A pitched roof has an incline of 15 degrees or more, typically much more.
