What should you do about a roof leak in Westminster?
Landlords with flats or HMOs in Westminster are generally expected to deal with leaks promptly once tenants report them. An emergency visit stops the water, and our written report and quote give you what you need to approve the permanent repair.
Westminster's flat roofs are mostly on shops with flat-roofed stores below flats above, with plenty on mansard and dormer loft conversions too. The Thames basin is one of the drier parts of Britain at roughly 730 mm of rain a year, but summer heat is the bigger test here: dark membranes on south-facing roofs swing a long way in temperature.
How much does an emergency leak repair cost in Westminster?
Guide price in Westminster: £220–£540 for an emergency temporary weatherproofing visit, including VAT at London rates. We confirm the price once we've traced the leak or seen the damage.
| Job | Guide price inc VAT |
|---|---|
| Emergency temporary weatherproofing visit | £220–£540 |
| Localised patch repair | £180–£600 |
| Upstand or flashing repair | £300–£780 |
| Condition survey and leak investigation | £180–£360 |
How quickly can someone come out?
We send a team for a temporary weatherproofing visit as soon as one is available. We don't promise a set response time, because demand jumps after storms and we would rather give you an honest answer on the phone than a figure we can't keep.
When you call, we ask a few questions about the roof and the leak so we can judge how urgent it is and what the team will need. Height matters: a single-storey garage or extension can usually be reached with ladders and edge protection, while a dormer or second-floor roof may need scaffold or a tower.
Safety comes before speed. In high winds, lightning or heavy rain, a team may not be able to work on the roof safely, and the visit may need to wait until conditions ease. Your best protection in the meantime is to contain the water indoors, as above.
What's included?
- Safe working, with edge protection on every job
- Temporary weatherproofing as soon as a team is available
- Advice by phone on keeping the water contained safely
- Written quote for the permanent repair or replacement
Building regulations in England
Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

How much does an emergency leak repair cost in Westminster?
£220–£540 for an emergency temporary weatherproofing visit, at London guide rates including VAT. We confirm the price once we've traced the leak or seen the damage.
Can I put a tarpaulin on my flat roof myself?
We'd advise against it. Getting onto a flat roof in bad weather is dangerous, and many roofs and rooflights are fragile. Contain the water indoors and call us instead.
Will my home insurance cover an emergency roof repair?
It depends on your policy and the cause. Storm damage is often covered, while wear and tear usually isn't, so check with your insurer. Notes made at the time, plus our written report, can help with a claim.
