Step 1

What do you need?

Tap one to see your price range.

Not sure what you need?

Leaking or worn out, and not sure if it needs a repair or a new roof? We look at it on a free quote visit, tell you which, and send a written quote. Pick Flat Roof Repair

Know it leaks but can't find where? Electronic leak detection pinpoints it, with a written report, for a flat £500 inc VAT. Pick Electronic Leak Detection

Need a written report, for a house purchase, an insurer or a tenant? That's a roof survey, a paid service for single ply and green roofs. Pick Roof Survey

Still not sure? Call us on 07807 815181 or send us a message and we'll point you the right way.

Homeowner prices include VAT. Commercial building? Pick Commercial Project.

Step 2

Roughly how big is the roof?

A guess is fine. Most domestic garages are 15–25 m². A full house extension is typically 30–60 m².

How to measure your roof
LENGTH (L) WIDTH (W) L × W = m²

Measure two sides of the roof in metres:

  1. The longest side (Length)
  2. The shortest side (Width)
  3. Multiply them together → that’s your m²

Example: a garage 5m long × 3m wide = 15 m²

Only if it’s safe
Don’t climb onto a roof you’re not confident on. Measure from the ground or an upstairs window, or tick “Not sure” and we’ll measure it for you at a free quote visit.

= ? m²

Step 3

    Sedum green roof in flower on a new stone garage in Sheffield

    Green roofs

    Thinking about a green roof?

    Pre-grown Fatra sedum over a root-resistant single ply roof. The estimator prices the whole job: the roof beneath, the sedum layer and an electronic leak test. Your firm price follows a free quote visit. A structural engineer confirms the structure can carry the green roof, and we install on the basis of their calculation. You arrange the engineer, and their fee is separate from our price.
