Roofs vary in size, height, scaffolding requirements, location, accessibility and most importantly the roofing material. This makes it impossible to accurately give the cost of a new roof. Roofers will not charge the same price as the cost of insurance, advertising and premises among other things differ from one contractor to the other.
Aluminium roofing systems will not cost the same as flat tiles roofing. Below is a rough price estimate of a new roof in the UK.For a start, you need to calculate the area the roof is supposed to cover in square metres. If all you need is a quick estimate of the area, you can measure from the floor of the house but if you need more accurate readings, you need to measure from a ladder. You need to calculate the rear area and the front area, then add a breakages allowance. If, for instance, the total area is 52 square metres, add 3 square metres breakages allowance to get 55 square metres. If 15.7 tiles are required for 1 square metre, then the whole house will need 864 roof tiles.
Now all you need is to get the price of one tile from suppliers and the cost of other materials then call your local contractor for a rough estimate of the cost of installation.
