Why choose torch-on felt roofing in Ferndown?
For a commercial roof in Ferndown, 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 a town like Ferndown, flat roofs are commonly found on terraced streets with flat-roofed rear kitchens and bathrooms or newer estates where the first extension roofs are now being replaced. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage.

How long does a torch-on felt roof last, and what is the guarantee?
A modern torch-on roof typically lasts 15 to 25 years, and high-performance systems with better membranes can last longer. That is a big step up from older felt roofs, which were often single-layer, unreinforced or poorly bonded.
What shortens the life of a felt roof is usually visible: mineral chippings worn away so the bitumen is exposed to sunlight, blisters where moisture was trapped, split laps, and upstands that have slumped or pulled away from the wall. Ponding speeds all of this up.
Manufacturer material guarantees are available on many specified torch-on systems; they often depend on a particular build-up and registration, which we handle where the system allows. Every re-roof also comes with our written workmanship guarantee, the length of which is stated in the quote, and insurance-backed options can be discussed. Our flat roof lifespan guide compares felt with the other systems.
What's included?

- Deck inspection with replacement of damaged boards
- Strip-off of the existing roof covering and removal of waste
- 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 Ferndown?
£1,550–£2,700 for a typical 18 m² garage roof in torch-on felt, at South West guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Why does my felt roof have blisters?
Blisters usually form when moisture or air trapped beneath the felt expands in the sun. A few small, intact blisters may be monitored, but widespread or split blisters point to a repair or replacement.
Is torch-on suitable for a block of flats?
Yes, layered bitumen systems are widely used on blocks of flats and commercial buildings. Larger roofs often use three layers and insulation, with hot works planned around residents.
