Why choose torch-on felt roofing in Romsey?
Torch-on felt suits property owners in Romsey who want a dependable, layered roof without paying the top price per square metre. With two or three bonded layers, a single small defect in one sheet need not lead to a leak, which is a real advantage on larger roofs that are hard to inspect often.
Romsey's flat roofs are mostly on lock-up garage blocks on estates, with plenty on bungalows with flat-roofed side extensions and dormers too. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.
How much does a torch-on felt roof cost in Romsey?
For Romsey we use South East rates: £1,650–£2,900 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.

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?

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 Romsey?
£1,650–£2,900 for a typical 18 m² garage roof in torch-on felt, at South East guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
How long does it take to lay a torch-on felt roof?
A garage roof typically takes one to two days and an insulated extension two to three. Larger roofs and blocks are phased over longer, with each area made weathertight before the team leaves.
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.
