Which flat roofs are common in South Yorkshire?
Flat roofs in South Yorkshire sit on lock-up garage blocks on estates, bungalows with flat-roofed side extensions and dormers and newer estates where the first extension roofs are now being replaced. England averages roughly 870 mm of rain a year; the Pennine side of Yorkshire is wetter and windier than the east, so we specify for the site rather than the county. Approximate 1991–2020 regional averages based on Met Office data.
Building regulations in England
Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. Renovated roofs over heated rooms are insulated to around 0.16 W/m²K where that's feasible, and new extension roofs are built to 0.15 W/m²K. In South Yorkshire the application goes to Sheffield City Council, Rotherham Council, City of Doncaster Council and 1 other council. More on the rules.
When is EPDM the right choice, and when is another system better?
EPDM is a strong choice for simple domestic roofs that people do not walk on, such as garages, single-storey extensions, porches and dormers. It is less suited to roofs with regular foot traffic or many pipes and vents.
Where it does well: few or no joins on small roofs, flexible in cold weather, tolerant of minor building movement, and laid without a flame.
Where it falls short: the finish is plain dark rubber, it can be punctured by dropped tools or sharp debris, and it is not designed as a walking surface without added protection. Roofs with many penetrations take a lot of careful detailing.
If you want a hard, walkable finish or a complex shape, GRP fibreglass often suits better. On a tight budget, or a larger roof where a layered system is preferred, torch-on felt is worth pricing. Liquid-applied roofing handles awkward details and overlays, single-ply membranes are built for larger commercial roofs, and mastic asphalt belongs on older and heritage buildings. Our EPDM vs GRP vs felt guide sets them side by side.
Do I need building regulations approval to replace a roof with EPDM?
Often, yes. In England, Wales and Northern Ireland, re-covering more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof should be insulated towards the renovation standard where that is feasible; in Scotland, the council's building standards service decides whether a building warrant is needed.
An unheated detached garage normally falls outside these rules, and a patch repair is treated differently from a full re-cover.
In practice that means a warm roof: insulation above the deck, a vapour control layer beneath it and the EPDM on top. The extra thickness lifts the finished roof, so at survey we check door thresholds, window cills, wall flashings and upstand heights, aiming for an upstand of about 150 mm above the finished surface. Where approval is needed, we deal with building control or building standards for you. The building regulations page and our warm vs cold roof guide go into more detail.

Which towns in South Yorkshire do you cover?
All of South Yorkshire. The main towns have their own pages below, and if yours isn't listed we still cover it: send your postcode and we'll confirm.
How much does an EPDM rubber roof cost in South Yorkshire?
£1,500–£2,650 for a typical 18 m² garage roof in EPDM, at Yorkshire and the Humber guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Which council handles building control for a flat roof in South Yorkshire?
It depends on where the roof is: in South Yorkshire that's Sheffield City Council, Rotherham Council, City of Doncaster Council and 1 other council. Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. We confirm which applies at the survey.
How long does it take to fit an EPDM roof?
A single garage typically takes one to two days and an insulated extension roof two to three, weather permitting. Larger roofs, scaffold and complex details add time.
Can an EPDM roof be fitted in winter?
Yes, as long as the deck is dry. The adhesives are affected by cold and damp, so very cold or wet days can delay bonding, and the roof is kept temporarily weathertight between dry spells.
Can EPDM be laid over an old felt roof?
Sometimes, but we usually recommend stripping old felt first. Overlaying hides any rot or wet insulation underneath, and over a heated room a full replacement is often when insulation has to be added anyway.
