Built-up systems, standing seam, single-ply membranes, green and biodiverse roofs. We work on packages where weather is the schedule risk and detail is the cost risk.
Six sector-specific risk patterns we see on UK roofing packages. Weather is the largest programme risk; detail is the largest cost risk.
Late autumn or winter install windows compress productivity. Without EWN discipline for adverse weather Relevant Events, the slip lands on you.
Drip detail, parapet, AOV interface, abutment flashings — small changes that compound to £100K+ over a programme if uncaptured.
Design responsibility lines blur on roof packages — designer, manufacturer, installer. We map & defend yours.
Penetrations through roof, service routing, parapet sequencing — all require multi-package coordination or rework is inevitable.
Roof systems also fall under BSA 2022 scrutiny. Combustibility, junction details with façade, fire-stopping all under review.
Roofing is defect-prone (water ingress, weathering). Without proactive defect closure, retention sits withheld for months — sometimes years.
Roofing is detail-heavy commercial work. EOT defence and retention release are the highest-leverage interventions on most packages.
Detail variation capture, final account, retention defence.
Adverse weather Relevant Events, EWN service, SCL Protocol.
Retention disputes, smash & grab on withheld payments.
Working at height, fall protection, post-Grenfell fire compliance.
Multi-trade sequencing with façade & M&E penetrations.
48-hour mobilisation on packages stuck in retention dispute.
Most roofing contractors leave retention sitting for 18+ months. With the right records discipline and HGCRA enforcement, retention is released on contractual date.
