Balconies and roof terraces in Leyland

A leak under a balcony in Leyland 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 Leyland need?

A roof terrace in Leyland 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.

Around Leyland, flat roofs are common on newer estates where the first extension roofs are now being replaced and on 1930s semis with flat-roofed garages and kitchen extensions. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour.

How much does balcony or terrace waterproofing cost in Leyland?

At North West guide rates, a 12 m² balcony in a liquid-applied system including scaffold comes to £1,800–£3,100 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?

  • Sealed details at doors, outlets, walls and balustrade posts
  • Written workmanship guarantee, with approvals handled where needed
  • New liquid, GRP, single-ply or asphalt waterproofing
  • Strip-out of the failed membrane and deck repairs

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 Leyland?

£1,800–£3,100 for a 12 m² balcony in a liquid-applied system including scaffold, at North West 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.

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.
