Why choose torch-on felt roofing in Sleaford?
For a commercial roof in Sleaford, such as a shop, surgery or club, torch-on felt offers a hard-wearing mineral finish that takes occasional maintenance traffic. Phased work keeps part of the building weathertight while the rest is re-roofed, so the business can usually keep trading.
In and around Sleaford, flat roofs are typically found on low-rise post-war blocks of flats, and on newer estates where the first extension roofs are now being replaced. 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 a torch-on felt roof cost in Sleaford?
For Sleaford we use East Midlands rates: £1,500–£2,550 is the guide for a typical 18 m² garage roof in torch-on felt, VAT included. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Single garage (18 m²), torch-on felt | £1,500–£2,550 |
| Extension (20 m²), felt, new deck + insulation | £2,650–£4,600 |
| Block of flats (150 m²), felt + insulation + scaffold | £15,250–£26,650 |
| Single garage (18 m²), EPDM rubber | £1,550–£2,750 |
| Extension (20 m²), EPDM, new deck + insulation | £2,750–£4,800 |
Should I choose torch-on felt or a different flat roof system?
Choose torch-on felt when you want a proven, layered system at a sensible price, particularly on larger roofs, blocks of flats and commercial buildings where several layers give useful redundancy. It is a weaker choice where hot works are hard to manage safely.
For: generally lower cost per square metre; two or three layers, so a single defect in one layer need not cause a leak; tough mineral finish; long track record and a British Standard code of practice; repairs can be made with compatible materials.
Against: needs a naked flame unless a cold-applied or self-adhesive alternative is used; shorter typical life than EPDM or GRP; the finish is functional rather than decorative; more laps to detail than a single sheet.
On small domestic roofs near timber, EPDM avoids the torch entirely. GRP gives a harder, neater surface. For an overlay, a liquid-applied system is often simpler. Large commercial roofs may suit single-ply, and older buildings may suit mastic asphalt. See our comparison guide.
What's included?
- Mineral-finished cap sheet, upstands, outlets and edge trims
- Vapour control layer and warm-roof insulation where needed
- Two- or three-layer reinforced bitumen membrane with staggered laps
- Hot-works checks and fire watch on every torch-on job
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 torch-on felt roof cost in Sleaford?
£1,500–£2,550 for a typical 18 m² garage roof in torch-on felt, at East Midlands guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Can torch-on felt be laid in wet weather?
Not in rain or on a wet deck, because moisture trapped under the membrane causes blisters. Light cold weather is usually workable, but we will postpone rather than lay on a damp surface.
Is torch-on felt better than the old felt roofs?
Yes, considerably. Modern torch-on membranes are polymer-modified and polyester-reinforced, laid in bonded layers, and typically last much longer than the older felt systems they replace.
