What do commercial flat roofs in St Ives need?
Businesses in St Ives need a roofing contractor who arrives with a plan, not just a price. We put the system, build-up, phasing, access and payment terms in a fixed written quote, and keep each section of the roof watertight before the team leaves site, so trading is not put at risk.
Around St Ives, flat roofs are common on shops with flat-roofed rear stores below flats and on terraced streets with flat-roofed rear kitchens and bathrooms. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof.

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 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 a commercial flat roof cost in St Ives?
£13,900–£22,850 for a 100 m² commercial roof in single-ply with insulation, at East of England guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
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.
What happens to air conditioning units and other roof plant?
Plant can often stay in place, with the new roof detailed around its supports. Where it has to be isolated and lifted, your mechanical contractor does that while we re-roof beneath it, and we agree the timing at survey stage.
