Roofer London Multi-Layer Waterproofing Membranes
SINGLE-POINT 30-YEAR GUARANTEES
As an approved Garland UK contractor, London Roofing Specialist delivers projects backed by Garland’s industry-leading Single-Point Guarantee for up to 30 years. Unlike split warranties where membrane manufacturers and contractors blame one another in the event of a leak, Garland UK accepts undivided liability for the technical specification, bespoke tapered insulation design, membrane manufacture, and on-site installation quality.
DEDICATED TECHNICAL MANAGER AUDITS
Every Garland project we undertake in London is surveyed, specified, and inspected throughout the build by a dedicated Garland UK Technical Manager, who issues photographic stage reports and signs off the finished roof prior to guarantee activation.
Flat Felt Roofer in London
We install the full suite of Garland UK reinforced bituminous systems—including StressPly Everton, StressPly Flex, Torch-On, and Flame-Free self-adhesive or cold-applied build-ups—tailored to the exact fire profile and thermal requirements of your building.
STRESSPLY ELASTOMERIC CAP SHEETS
Reinforced with dual polyester and glass-fibre mats, Garland cap sheets achieve exceptional tensile strength and elongation, accommodating seasonal structural movement on Victorian crown roofs and concrete podium decks without splitting at the lap joints.
PART L WARM ROOF & TAPERED INSULATION
Laid over a high-performance vapour control layer, rigid PIR or non-combustible mineral wool thermal insulation, and a robust elastomeric underlay, our three-layer Garland systems eliminate ponding water and cut winter heat loss to below 0.18 W/m²K.

Homeowners, surveyors, and block managers across London increasingly specify Garland UK multi-layer bituminous systems over single-layer membranes where heavy foot traffic, rooftop plant maintenance, or falling slate impact could puncture a thinner 1.2mm sheet. With a combined waterproofing thickness exceeding 7mm to 9mm across the vapour barrier, underlay, and mineral-surfaced cap sheet, a Garland built-up felt roof shrugs off mechanical abuse while maintaining full BROOF(t4) fire compliance.

Frequently Asked Questions: Garland Felt Roofer London
Can Garland felt systems be installed without naked gas flames on timber roofs?
Yes. Where buildings contain dry Victorian timber decks, thatched or shingled junctions, or strict hot-works insurance exclusions, we specify Garland UK’s Flame-Free self-adhesive and cold-bonded bituminous membranes, sealing laps with calibrated hot-air welders rather than gas torches.
How does modern Garland SBS felt differ from traditional mineral felt?
Traditional oxidised bitumen felt becomes rigid in winter frosts and softens under summer sun, causing it to blister and crack within 10 years. Garland UK modifies its bitumen with SBS synthetic rubber modifiers and spunbond polyester reinforcement, allowing the membrane to stretch, recover, and remain completely watertight for over 30 years.
