Who we are
A flat roofing contractor that turns up, and finishes
Balmoral Flat Roofing was established in 1990 by Shane Crossland and has been based in Mansfield Woodhouse ever since. We specialise in flat roofing only — built-up felt, liquid applied waterproofing, and the deck, insulation and drainage that sit beneath them.
That focus means we are not learning on your roof. Our operatives are CSCS certified and UKATA trained, our work is insured to £5m public liability, and every job is signed off by the same team that surveyed it.
- Flat roofs only. No general building work, no subcontracted crews.
- Honest recommendations. If a repair is the better spend, we will say so.
- Written quotations. Priced line by line, with any exclusions stated up front.
- Work that is inspected. Final checks on drainage, upstands and lap sealing before we leave.

Systems we install
Choosing the right membrane matters more than the brand on the box
Two systems cover almost every flat roof we are asked to price. Knowing which one your roof actually needs — and when a third is overkill — is the part that saves money.
System 01
Torch-on felt (built-up bitumen)
The traditional East Midlands workhorse, and still the most cost-effective answer for most garages, extensions and low-slope roofs. Layers are heat-fused to each other rather than glued, so the finished covering is a single bonded sheet with no glue lines to fail.
System 02
Liquid waterproofing — ARBOFLEX PU
Cold-applied polyurethane that cures into a seamless rubber membrane. Because it is painted on, it wraps rooflights, pipe penetrations and awkward junctions that a sheet material simply cannot follow — and it can usually be applied over the existing covering, so there is no strip-out and very little disruption.
How we work
From first phone call to final inspection
Four steps, no surprises, and a named contact throughout.

Frequently asked
Flat roofing questions, answered
The questions we are asked most often — answered properly, without the sales language.
As a 2026 guide for the East Midlands, torch-on felt runs about £60–£100 per m² installed, liquid waterproofing £75–£130, and GRP fibreglass £90–£140. Most domestic replacements land between £1,800 and £5,000 all in. Scaffolding, timber deck repairs and insulation upgrades are priced separately and always listed on the quotation.
We quote by survey, so the number you get is for your roof — not an average pulled off a website.
No. Surveys and written quotations are free and carry no obligation. If a repair will buy you another few years, we will tell you that instead of quoting for a replacement.
A properly installed built-up felt roof typically gives 10–20 years. Liquid waterproofing systems such as ARBOFLEX PU are usually specified at 20–25 years. Lifespan comes down to three things: the quality of the deck beneath, whether water can drain away, and whether anybody has walked on it.
Yes. We carry £5 million public liability and £10 million employers' liability insurance, and certificates can be issued to commercial clients and principal designers. Our operatives are CSCS certified, UKATA asbestos-trained, and DBS checked.
Both, and we have done for over three decades — from schools, healthcare buildings and leisure centres to warehousing, retail units and domestic extensions. Commercial work is usually programmed around your operating hours to keep disruption down.
Often, yes. Blisters, failed laps, localised ponding and split flashings can frequently be cut out and repaired, or the whole roof re-coated with a liquid system over the top. It depends on the condition of the deck and how much water has already got in — which is why we inspect before we quote.
