Sikabit Pro Bituminous Roofing Contractor London
MULTI-LAYERED UV & WEATHERING QUALITY
Manufactured and UKCA/CE marked to BS EN 13707, SikaBit Pro cap sheets incorporate a composite spunbond polyester carrier scrim encapsulated within dual-compound modified bitumen. Subjected to 2,000 hours of accelerated Xenon-arc weathering and 800 hours of UNI 8629 QUV solar and rainwater cycling, the mineral-slated surface resists thermal blistering, hailstone impact, and ultraviolet degradation across exposed London rooftops.
PART L WARM ROOF THERMAL INTEGRITY
Laid over a SikaBit vapour control layer, rigid Sikatherm PIR or non-combustible mineral wool insulation boards, and a self-adhesive or torch-bonded underlay, the system forms a monolithic thermal envelope that eliminates cold bridging and interstitial condensation.
Benefits of SikaBit Pro Bituminous
Roofer London SikaBit Pro Bituminous
NFRC SAFE2TORCH & FLAME-FREE SAFETY
Every SikaBit Pro specification we design adheres strictly to NFRC Safe2Torch guidelines. Where roofs abut dry Victorian timber eaves, sash window boxes, or combustible upstands, we install flame-free self-adhered SikaBit membranes and cold-applied Sikalastic liquid detailing, achieving full BROOF(t4) external fire compliance under BS 476 Part 3 and BS EN 13501-5.
SBS/APAO ELASTICITY & 80MM WELDED SEAMS
By pairing SBS elastomeric stretch with APAO heat resistance around a tough polyester core, SikaBit Pro absorbs seasonal structural movement without fatiguing. Precision-formed 80mm selvedge side laps fuse into a continuous, double-sealed joint that stops standing rainwater from tracking beneath the sheet.

Frequently Asked Questions: SikaBit Pro Flat Roofer London
Why choose SikaBit Pro over a single-layer membrane for a London green roof or terrace?
Once a sedum green roof, soil substrate, or porcelain paving system is laid over a flat roof, the waterproofing membrane is buried beneath heavy dead loads. SikaBit Pro provides a multi-layer thickness exceeding 8mm with certified root-barrier protection, offering far greater resistance to mechanical puncture during landscaping works than a thin single-layer sheet.
Can SikaBit Pro be installed on a roof with restricted flame zones?
Yes. Following our pre-start Safe2Torch survey, we combine self-adhesive SikaBit carrier layers and hot-air or liquid-applied perimeter detailing around all timber kerbs, skylights, and eaves, ensuring zero naked flames come near combustible building elements.
