What does a balcony or terrace in Strood need?

A roof terrace in Strood may be re-waterproofed when the owners want to change the finish, swapping old tiles for decking or porcelain on pedestals. Lifting the surface exposes the membrane, and replacing it then avoids having to lift the new finish again later.

Strood's flat roofs are mostly on lock-up garage blocks on estates, with plenty on newer estates where the first extension roofs are now being replaced too. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.

How much does balcony or terrace waterproofing cost in Strood?

At South East guide rates, a 12 m² balcony in a liquid-applied system including scaffold comes to £2,100–£3,600 including VAT. The fixed price comes after a free survey for new and replacement roofs.

JobGuide price inc VAT
Balcony (12 m²), liquid-applied, scaffold£2,100–£3,600
Single garage (18 m²), EPDM rubber£1,750–£3,100
Extension (20 m²), GRP, new deck + insulation£3,300–£5,900

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?

  • Free survey of the deck, falls, outlets and door thresholds
  • Strip-out of the failed membrane and deck repairs
  • New liquid, GRP, single-ply or asphalt waterproofing
  • 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 Strood?

£2,100–£3,600 for a 12 m² balcony in a liquid-applied system including scaffold, at South East guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

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.

How long does balcony waterproofing last?

It depends on the system and how well it is protected. As indicative ranges, liquid-applied systems last 10–25+ years by product and mastic asphalt 30–60, with good maintenance.
