What do commercial flat roofs in Westhill need?
A commercial re-roof in Westhill has to fit around customers, staff and deliveries. We agree working hours, skip positions and access routes before we start, keep fire exits clear throughout, and choose a flame-free system where your site does not allow hot works near stock or occupied rooms.
Westhill's flat roofs are mostly on bungalows with flat-roofed side extensions and dormers, with plenty on low-rise post-war blocks of flats too. Scotland averages roughly 1,570 mm of rain a year, with the west far wetter than the east, so drainage, falls and wind uplift are part of every specification we write.
How much does a commercial flat roof cost in Westhill?
For Westhill we use Scotland rates: £12,550–£20,700 is the guide for a 100 m² commercial roof in single-ply with insulation, VAT included. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Commercial roof (100 m²), single-ply + insulation | £12,550–£20,700 |
| Condition survey and leak investigation | £140–£290 |
| Block of flats (150 m²), felt + insulation + scaffold | £14,750–£25,850 |
Which roofing system suits a commercial flat roof?
Single-ply membrane usually suits large, simple roofs; built-up felt suits roofs with heavy foot traffic, plant or complex detailing; and a liquid-applied overlay suits a sound roof that needs new waterproofing without a full strip-out.
- Single-ply (PVC, TPO or FPO): light and quick to lay over large areas, with hot-air welded laps and fixing or bonding designed for the site's wind uplift. Indicative life 25–35+ years. See single-ply roofing.
- Built-up felt: two or three layers of reinforced bitumen membrane laid to BS 8217, hard-wearing around plant and maintenance routes. Modern systems last 15–25 years, high-performance systems longer. See torch-on felt roofing.
- Liquid-applied overlay: a reinforced coating that cures to one continuous layer, well suited to pipework, plant bases and awkward details. Indicative life 10–25+ years depending on the product. See liquid roofing.
Mastic asphalt suits concrete decks and walkways, and EPDM suits simpler roofs with few penetrations. An overlay only works where the existing roof is dry and firmly bonded, so we check for wet insulation before recommending one (see overlay or strip).

Building standards in Scotland
In Scotland the building standards technical handbooks (Section 6 for energy) apply, and the council's building standards service decides whether a building warrant is needed. Like-for-like repairs to a roof covering can be exempt; alterations, structural work and new roofs usually need a warrant before work starts. The domestic roof benchmark is 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. More on the rules.

£12,550–£20,700 for a 100 m² commercial roof in single-ply with insulation, at Scotland guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Can you re-roof while our premises stay open?
Usually, yes. We phase the work so each section is watertight before the team leaves site, keep entrances and fire exits clear, and agree working hours and deliveries with you first.
Do you need a hot works permit?
Only if torch-on felt or other naked-flame work is used, in which case the team works under your permit system with a fire watch afterwards. Where hot works are not allowed, we specify a flame-free system such as a cold-applied membrane.
