Commercial Roofing — Surveys, Overlays & Planned Maintenance
We keep commercial roofs safe, watertight and predictable to run. From condition surveys and overlay designs to reactive call-outs and planned maintenance, our approach is practical and compliant. We work around live operations with clear RAMS, permits and segregation, and we provide photo-rich reports so decisions are easy to justify. Where life remains, we specify overlay systems to extend service with minimal disruption; where it doesn’t, we rebuild with warm-roof details, corrected falls and durable trims. The aim: fewer leaks, safer access and a clear, budgetable plan for the years ahead.
Compliance & Safety
Industrial and retail sites demand disciplined H&S. We produce site-specific RAMS, coordinate permits (roof access, hot works, MEWP), and install edge protection or demarcation lines to keep everyone safe. Briefings are held daily; exclusion zones are signed, and deliveries are timed to suit your peak hours. Our teams are trained for fragile-roof protocols, asbestos awareness and emergency procedures. Expect tidy housekeeping, clear walkways and a zero-surprise approach that keeps the roof programme invisible to customers and staff.
RAMS, Permits & Edge Protection
We agree a permit regime with your FM or principal contractor, issue RAMS for approval and erect the right protection—handrails, temporary guardrails or man-safe lines—before work starts. Where access relies on MEWP, operators are certified and ground bearing is checked. Hot works are controlled, monitored and signed off. Records are logged daily so compliance is auditable.
Out-of-hours & Segregation
When trading hours or production can’t be interrupted, we work evenings or early mornings with acoustic controls and protected access routes. Below, we install debris netting and drip protection; above, we fence work zones and mark routes to plant and rooflights. Fire exits and emergency routes are kept clear at all times, agreed in the pre-start and re-checked at handover.
Condition Surveys & Reporting
Decisions need evidence. We walk every area, lift sample laps, check fixings, scan for trapped moisture and confirm outlet performance. Rooflights, joints, laps and perimeter details are photographed and tagged on a plan. You get a concise report with colour-coded priorities and budget options for repair, overlay or replacement. Where multiple blocks exist, we create an asset register so maintenance and spend can be phased intelligently.
Moisture Checks & Photos
We combine visual inspection with moisture readings and core samples where agreed. This confirms whether overlay is viable or if wet insulation demands strip-out. Photos show defects and upstream causes—blocked gutters, poor falls, split laps—so fixes target the root, not just the symptom.
Asset Registers & Priority Plans
Each roof area is given an ID with notes on type, age, defects and risk. Actions are grouped by urgency and lifecycle impact, helping you schedule works across financial years. The register becomes the baseline for future checks and warranty tracking.
Flat Roof Refurbishment
We extend roof life with overlays where the deck is sound, or deliver full replacements where it isn’t. Designs address insulation, drainage and detailing at perimeters and penetrations. Warm-roof systems improve energy and condensation performance; cut-to-falls schemes remove ponding. All interfaces—parapets, gutters, rooflights—are upgraded to system details so warranties are meaningful and maintenance is simple.
Overlay Systems & Warm Roofs
On dry, stable substrates we clean, prime and overlay with a compatible system (e.g., single-ply or liquid) to manufacturer specification. Warm-roof build-ups add VCL and insulation, improving U-values and protecting the deck from thermal stress—often the most cost-effective route for busy sites.
Cut-to-falls Insulation & Outlets
Tapered insulation removes long-term ponding without screeds. We set planes to existing outlets, add crickets behind obstacles and increase outlet capacity or add overflows where needed. The result is a roof that drains quietly instead of holding water.
Industrial Gutters & Rooflights
Factory gutters and aged rooflights are frequent leak points. We line gutters with continuous systems, upgrade outlets and leaf control, and re-detail joints and end laps. Rooflights are replaced or over-sheeted to boost light levels and cut leaks while maintaining safety with compliant grids where required. Works are sequenced to keep the building dry throughout.
Lining Systems
We install continuous gutter liners with welded joints, sumps and expansion allowance, or form liquid linings to complex geometries. Terminations tie into roof membranes cleanly, and access covers remain serviceable.
Domes, Barrels & Safety Grids
Old, brittle units are swapped for clear, multi-skin domes or barrel vaults with better thermal performance. Safety grids or barriers are installed to control fragile-roof risk. Daylight improves while maintenance and leak risk drop.
Reactive Repairs & SLAs
When a leak hits, speed and clarity matter. We offer call-outs with agreed SLAs, arrive safe and equipped, make the area watertight and document the fault. Permanent repairs are quoted with photos and cause-and-effect notes so you can claim or plan with confidence. For multi-site clients, we standardise the reporting so approvals are quick and consistent.
Leak Call-outs & Make-safe
Technicians attend with access, temporary sealing materials and signage. We isolate the ingress, protect sensitive areas below and record before/after. If the cause is systemic (e.g., failed lap detail), we propose a scalable fix rather than repeat visits.
Planned Maintenance
Annual or biannual visits keep roofs reliable and predictable. We clear gutters, test outlets, check laps/flashings and tighten fixings. Minor defects are corrected on the spot; larger ones are quoted with photos. Trend data from repeat visits informs budgets and avoids emergency spend.
Annual Inspections & Cleaning
Visits are scheduled around seasons and site peaks. We remove debris, flush gutters, verify back-up overflows, and inspect perimeters and penetrations. A short, photo-rich report confirms status and actions taken, with advisories for the next cycle.
