Overview
Roof cleaning and maintenance is a planned visit where the roof surface is cleaned down, outlets and gutters are cleared, debris and vegetation are removed, and every detail, upstands, kerbs, terminations, penetrations, laps, is checked and reported on. Small faults are corrected before they become water ingress.
Commercial owners and managing agents with property portfolios, landlords with let property, homeowners with a flat roof they never see, and anyone who has just had a new roof installed and wants to protect it.
Ideally on a planned schedule, and always after autumn leaf fall and after storms. Also when you can see standing water that never clears, moss and vegetation on the membrane, or debris around outlets.
Flat roofs do not fail suddenly. They fail slowly, at the outlets, at the details and at the points where debris holds water against the membrane. Regular clearance and inspection is the cheapest roofing work there is, and it is the only work that reliably prevents the expensive kind.
What happens if it is left
A single blocked outlet turns a drained roof into a tank. Standing water finds the weakest detail, and the added load on the deck is a structural concern on larger roofs.
Moss and self-seeded plants hold moisture permanently against the surface and can push roots into laps and details.
A lifted lap or a split at an upstand costs very little to correct while it is a detail. Left through a winter it wets the insulation, and then the whole build-up needs replacing.
Neglect is neglect. Roofs left with blocked drainage and unaddressed damage are not the same proposition as a maintained roof when something goes wrong.
Our process
Full walk of the roof: membrane condition, laps and welds, upstands, kerbs, penetrations, trims and outlets, plus any signs of ponding or movement.
Debris, silt, moss and vegetation removed from the membrane surface using methods appropriate to the system, no aggressive washing that damages the covering.
Outlets, gutters, hoppers and downpipes cleared and checked for flow, with overflow provision inspected.
Minor defects corrected on the visit where practical, and anything larger reported with photographs and a fixed-price quotation to fix it.
You get a clear account of the roof's condition, and we can set a schedule for the next visit so it does not get forgotten.
What you get
Clearance and early correction cost a fraction of the strip-out and insulation replacement that follows neglect.
Water that leaves the roof cannot find a weak detail, which is the whole basis of flat roof longevity.
We report what we find with photographs, so you are deciding on evidence rather than reacting to a stain.
Photographic records support service charge budgeting, planned maintenance programmes and insurer or purchaser queries.
A maintained membrane reaches the end of its design life. An unmaintained one rarely does.
Any remedial workmanship we carry out is covered by our 10-year workmanship guarantee.
In detail
Field membrane inspected for splits, punctures, lifted laps and impact damage. Upstands and terminations checked for slippage, open edges and failed trims. Kerbs, rooflights and plant plinths checked all round. Penetrations and collars checked. Outlets, gratings and gutters cleared and flow-tested. Ponding areas noted and photographed. Debris, stored materials and vegetation removed.
Cleaning is matched to the covering. Single-ply membranes tolerate appropriate cleaning but not aggressive high-pressure washing, which can damage the surface and force water into laps. Liquid systems and older bituminous coverings each have their own tolerances. The point of cleaning is to remove what holds water and hides defects, not to make the roof look new.
Outlet capacity, leaf guards and overflow provision matter as much as clearance. On roofs where ponding persists after clearance, the problem is fall or outlet position rather than debris; we will say so, and set out what a refurbishment would need to do to correct it rather than selling repeat visits that cannot solve it.
Managed properties benefit from scheduled visits with consistent reporting so condition can be tracked year on year and budgets planned rather than reacted to. We provide RAMS for commercial works and are asbestos awareness trained for older stock. Detailed roof inspections and photographic reports may be chargeable, and we tell you the cost before we do them.
High winds lift trims and edge details, and debris impact punctures membranes. A post-storm check is worth doing on any exposed roof, because wind damage often does not leak until the next sustained rainfall, by which point the roof has been open for weeks. Emergency leak and storm-damage call-outs are accommodated where possible.
A new single-ply or liquid roof still needs its outlets kept clear and its details left alone. Where other trades access the roof for plant, aerials or window cleaning, foot traffic and dropped tools are the main risks, a defined walkway and a periodic check protect the investment and the guarantee position.
