What makes a quote go up — or down
- What has to come off first. Removing a failed membrane or saturated screed is often more work than the new system.
- Details. Roofs crowded with AC units, pipes and tank stands have more upstands to reinforce.
- Falls. Correcting ponding with new screed adds cost — and is why a roof stays dry.
- Access. Towers need permits, lift bookings and safe roof access.
- Size. Small jobs carry a minimum charge; larger areas cost less per m².
Why the cheapest quote often costs the most
A low price per m² usually means a coating over the old, failed layer — no preparation, no detailing at drains and upstands, and no flood test. When it leaks again next winter, you pay twice. Compare quotes on scope: is the leak source confirmed, is the old system removed, are the details reinforced, is there a flood test, and will they come back if it leaks again?
