What does a balcony or terrace in Glen Parva need?
Settled, rocking or cracked paving is a common reason to re-waterproof a terrace in Glen Parva. Slabs bedded directly on the membrane can damage it over time. Relaying them on adjustable pedestals protects the waterproofing and gives a level surface that drains underneath.
Around Glen Parva, flat roofs are common on 1960s and 1970s link-detached houses with flat-roofed garages and porches and on 1930s semis with flat-roofed garages and kitchen extensions. The East Midlands is drier than the west of Britain, so most flat roofs here fail through age, UV and poor detailing at upstands rather than sheer rainfall.
How much does balcony or terrace waterproofing cost in Glen Parva?
At East Midlands guide rates, a 12 m² balcony in a liquid-applied system including scaffold comes to £1,850–£3,200 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 | £1,850–£3,200 |
| Single garage (18 m²), EPDM rubber | £1,550–£2,750 |
| Extension (20 m²), GRP, new deck + insulation | £2,950–£5,300 |
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?

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.

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.
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.
