Why choose torch-on felt roofing in Saffron Walden?
Where a flat roof in Saffron Walden already has a felt covering and the building owner wants like-for-like, torch-on is the natural replacement. The old roof is stripped, the deck checked and the new layers laid, often with warm-roof insulation added when the space below is heated.
Around Saffron Walden, flat roofs are common on 1960s and 1970s link-detached houses with flat-roofed garages and porches and on bungalows with flat-roofed side extensions and dormers. 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.

Does replacing a felt roof mean upgrading the insulation?
Usually, yes, when the roof is over a heated space and more than half of it is being re-covered. In England, Wales and Northern Ireland that is renovation of a thermal element, which should be brought towards the renovation U-value where feasible; a Scottish project goes through the council's building standards service, which confirms whether a warrant applies.
A felt replacement is a good point to switch to a warm roof, with insulation laid above the deck under the new membranes. On larger roofs, tapered insulation can also correct poor falls that have caused ponding, which a patch repair cannot fix. Raising the roof level affects upstands and door thresholds, so we check heights at survey. Any approval is arranged by us as part of the job, and the building regulations page sets out the rules by nation.
What's included?
- Two- or three-layer reinforced bitumen membrane with staggered laps
- Hot-works checks and fire watch on every torch-on job

- Mineral-finished cap sheet, upstands, outlets and edge trims
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 Saffron Walden?
£1,600–£2,750 for a typical 18 m² garage roof in torch-on felt, at East of England guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Can I paint or coat an old felt roof?
Reflective or liquid coatings can extend the life of a sound felt roof, but they will not fix wet insulation, a rotten deck or poor falls. A survey shows whether coating or replacement makes more sense.
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.
