Balconies and roof terraces in West Bromwich

A leak under a balcony in West Bromwich usually shows up as a stain on the ceiling below, but the cause is often at the door threshold or an outlet. We trace it at survey, then waterproof the whole balcony properly rather than sealing one spot and hoping for the best.

What does a balcony or terrace in West Bromwich need?

A roof terrace in West Bromwich 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.

In a large town like West Bromwich, flat roofs are commonly found on shops with flat-roofed rear stores below flats or 1930s semis with flat-roofed garages and kitchen extensions. 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 West Bromwich?

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.

Which waterproofing system is best for a balcony?

For most small balconies, a liquid-applied membrane is the practical choice, because it is brushed or rolled on and forms one continuous layer around posts, door frames and outlets with no seams to fail. Many systems include a hard-wearing, anti-slip topcoat.

GRP fibreglass gives a rigid, walkable surface and suits balconies left exposed rather than paved. On larger roof terraces under paving or decking, single-ply membranes are common, and mastic asphalt has a long record on concrete terraces and blocks of flats.

The choice also depends on what goes on top. Paving on pedestals protects the membrane, while an exposed balcony needs a system rated for foot traffic in its own right. We specify the build-up at survey.

What's included?

  • Written workmanship guarantee, with approvals handled where needed
  • Lifting and setting aside of existing paving or decking
  • New liquid, GRP, single-ply or asphalt waterproofing
  • Free survey of the deck, falls, outlets and door thresholds

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.

Who checks building regulations for a flat roof in West Bromwich?

Where the work needs approval it goes to Sandwell Council building control, or a registered building control approver. We tell you at the survey whether your job needs it and deal with the paperwork as part of the quote.

How much does balcony or terrace waterproofing cost in West Bromwich?

£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.

Can I put decking straight onto my flat roof?

Not directly onto the membrane. Decking needs a supporting system that spreads the load and lets water drain, and the roof must be checked for the extra weight.

Do you install balustrades?

Our work is the waterproofing and drainage. We detail the membrane around balustrade fixings so they stay watertight, and we can advise on where posts should be fixed.
