What does a balcony or terrace in Telford need?
Owners of flats in Telford sometimes find that a neighbour's balcony is leaking into their home. Where a balcony serves one flat but sits over another, the repair needs proper waterproofing and drainage, and a clear written specification helps everyone involved agree the work.
In a city like Telford, flat roofs are commonly found on terraced streets with flat-roofed rear kitchens and bathrooms or low-rise post-war blocks of flats. England averages roughly 870 mm of rain a year and the West Midlands sits close to that, so falls and outlets are the difference between a roof that drains and one that ponds.
How much does balcony or terrace waterproofing cost in Telford?
At West Midlands guide rates, a 12 m² balcony in a liquid-applied system including scaffold comes to £1,900–£3,250 including VAT. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Balcony (12 m²), liquid-applied, scaffold | £1,900–£3,250 |
| Single garage (18 m²), EPDM rubber | £1,600–£2,800 |
| Extension (20 m²), GRP, new deck + insulation | £3,000–£5,400 |
How long does it take to waterproof a balcony?
A small balcony is typically waterproofed in two to four working days, plus time for scaffold if it is above ground floor. Liquid and GRP systems need dry weather and cure time between coats, which sets the pace.
The balcony door will be out of use while the membrane is laid and curing, and the room behind may be noisy while old paving or screed is broken out. If the team needs to work through the house, we agree a route and protect floors. Larger terraces with paving or decking take longer, because the finish has to be lifted and reinstated. Resin systems smell while they cure, so nearby windows are best kept closed.
What's included?
- New liquid, GRP, single-ply or asphalt waterproofing
- Free survey of the deck, falls, outlets and door thresholds
- Strip-out of the failed membrane and deck repairs
- Sealed details at doors, outlets, walls and balustrade posts
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 balcony or terrace waterproofing cost in Telford?
£1,900–£3,250 for a 12 m² balcony in a liquid-applied system including scaffold, at West Midlands guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Why is water coming through the ceiling below my balcony?
The usual causes are a failed door threshold, a blocked or poorly sealed outlet, or a fixing through the membrane. A survey, sometimes lifting paving, finds the source.
Is a roof terrace heavier than a normal flat roof?
Yes. Paving, people, planters and furniture all add load, so a structural engineer should confirm the roof can carry it before a terrace is formed.
