Roof size
The measured area, number of slopes and total ridge, verge and valley lengths determine material and labour quantities.
Straightforward pricing guidance
Every roof is different, so a reliable price needs a survey. This guide explains the main factors behind a quotation and helps you compare proposals fairly.
— What changes the price?
A low headline figure can be misleading if scaffolding, waste, leadwork or essential roof details have been left out.
The measured area, number of slopes and total ridge, verge and valley lengths determine material and labour quantities.
Hips, valleys, dormers, roof windows and steep pitches require more cutting, detailing, access and installation time.
Materials differ in purchase cost, coverage per square metre, fixing method, weight and the time needed to lay them.
Conservatories, narrow side passages, extensions, public pavements and limited delivery space can alter the access plan.
Rotten rafters, failed decking or damaged roofline timbers may only become fully visible once the roof is stripped.
Chimneys, abutments and valleys need skilled detailing. Guttering and eaves arrangements may also need adjustment.
Upgrades can improve performance and help the roof meet current requirements, but must be specified for the building.
— Comparing roofing quotes
Ask whether the price includes scaffolding, skips or waste removal, membrane, battens, ridge and verge work, leadwork, ventilation, making good and applicable warranties. Confirm what happens if hidden timber repairs are required.
A well-written quotation helps prevent misunderstandings and makes different proposals easier to compare. If a detail is unclear, ask before accepting the work.
— A price for your actual roof
A photograph or rough house type does not reveal access, pitch, junctions, hidden coverings or structural condition. An inaccurate instant price can create false expectations.
