Torch on felt roofing is a proven solution for flat roofs where strong weather protection and durability are required. Torch on felt roofing is commonly used on garages, extensions, and residential flat roofs to provide a layered waterproof system that resists leaks and surface wear.
This system is applied using heat bonded layers to create a secure seal across the roof surface. Torch on felt roofing is suitable where long term protection is needed without frequent maintenance or repeated repairs.
Torch on felt systems are commonly installed as part of broader roofing services that help maintain strong waterproof protection across flat roof structures.

Every torch on felt roofing project is delivered as a managed service. We focus on preparation, correct layering, and controlled application to ensure the felt bonds properly and performs as intended.
Our work prioritises waterproofing, surface strength, and edge security. All installation stages follow guidance from the British Standards Institution to reduce risk and improve roof lifespan.
If the roof surface develops cracks or leaks over time, targeted flat roof repairs can restore protection without replacing the entire roofing system.
Our service covers everything required to deliver a finished and weather resistant flat roof. We assess the existing surface, prepare the structure, and apply the felt system using approved techniques.
Where required, we also improve drainage and edge protection to reduce the risk of standing water and future damage. Another durable flat roof system is GRP fibreglass roofing, which provides a seamless waterproof surface often used on garages and extensions.
We install complete torch on felt systems on new flat roof structures. This includes full deck preparation, primer application, and heat bonded felt layers finished with edge trims and weatherproof sealing.
When an existing felt roof has failed or reached the end of its lifespan, we strip the old system, inspect the deck for rot or damage, and install a new torch on felt system to current standards.
We carry out targeted repairs where the existing system is mostly sound but has developed localised cracking, lifting edges, or failed seals. Repairs are completed using compatible torch on felt materials to restore waterproofing without full replacement.
Herringbone is one of the most popular timber flooring patterns in the UK, using rectangular planks laid at 45 or 90 degree angles to create a striking chevron effect. We install herringbone flooring in solid and engineered oak using glued installation on prepared subfloors, ensuring correct alignment and precise border detailing throughout.
Reclaimed timber flooring uses original boards salvaged from old buildings, warehouses, and industrial properties. Each board carries its own character, grain, and patina that cannot be replicated in new timber. We install reclaimed flooring on prepared subfloors with appropriate moisture protection and structural assessment before installation begins.
We install a range of hardwood flooring species beyond oak including walnut, ash, maple, and iroko depending on the design requirements and budget. Every hardwood installation includes subfloor assessment, moisture testing, and correct acclimatisation of the boards before fitting begins.
Torch on felt roofing fails most often because of poor surface preparation and rushed heat application. EBT Build treats every flat roof job with the same level of preparation, whether it is a single garage or a full extension roof. We do not subcontract, we do not rush, and we do not cut corners on the stages that matter most.
Every project is managed from first survey through to final handover. Our team follows British Standards Institution guidance on heat application, overlap requirements, and edge detailing to make sure the finished roof performs for its full lifespan.

Torch on felt roofing is used primarily on flat roofs for garages, extensions, dormer roofs, porches, and commercial properties. The system works by heat bonding multiple layers of bitumen felt onto the roof deck, creating a waterproof barrier that resists rain, wind, and surface wear. It is one of the most widely used flat roofing systems in the UK because it is durable, cost effective, and suitable for a wide range of roof sizes and structures. Torch on felt is particularly popular for garage roofs and single storey extensions where long term waterproofing is the priority.
A properly installed torch on felt roof typically lasts between 15 and 25 years depending on the quality of materials used, the standard of installation, and how well the roof is maintained. The key factors that affect lifespan are surface preparation before installation, the number of felt layers applied, and how well the edges and upstands are sealed. Roofs that are inspected periodically and have minor issues addressed early will consistently last longer than those that are left unattended. Choosing an experienced and insured roofing contractor is the single most important factor in getting the full lifespan from a torch on felt system.
Torch on felt roofing offers stronger and more reliable bonding than cold applied felt systems. Because the felt is heat bonded directly to the roof deck and to each layer beneath it, there is far less risk of lifting, bubbling, or water penetration over time. Cold applied felt uses adhesives rather than heat, which can be less consistent and more vulnerable to movement in extreme temperatures. For residential flat roofs, extensions, and garages where long term durability is important, torch on felt is generally considered the superior option. Cold applied systems may be suitable for very minor repairs or areas where open flame working is not practical.
In some cases torch on felt can be installed over an existing felt surface, but only if the existing deck is structurally sound, dry, and free from significant damage or rot. If the existing felt is blistered, cracked, or retaining moisture, it must be removed before new felt is applied. Installing over a failing surface traps moisture beneath the new layers and leads to premature failure. A proper inspection is always carried out before any installation decision is made. Where the existing roof deck is damaged or soft, boarding repairs or full deck replacement will be recommended before the new felt system goes down.
The cost of torch on felt roofing in the UK typically ranges from £40 to £90 per square metre depending on the size of the roof, the number of felt layers required, the condition of the existing deck, and access requirements. A standard garage roof of around 15 to 20 square metres would typically cost between £800 and £1,800 fully installed. Larger flat roof extensions will cost more depending on scope and specification. Prices vary between contractors so it is always advisable to get at least two or three written quotes before committing. All quotes from EBT Build are provided in writing with a full breakdown of materials and labour.
There are several clear signs that a torch on felt roof is reaching the end of its life or has been poorly installed. Visible blistering or bubbling on the surface indicates that moisture has become trapped beneath the felt layers. Cracking or splitting along the surface or at the edges suggests the felt has dried out and lost its flexibility. Water stains on ceilings directly below the flat roof are a strong indicator of felt failure or a failed edge seal. Pooling water that does not drain within 24 to 48 hours after rainfall points to drainage or surface problems that need attention. If your felt roof is more than 15 years old and showing any of these signs, a full inspection and likely replacement is recommended.
