Croydon has a bigger stock of flat roofing than most towns of its size, and it is the reason so much of the roofing work here is commercial rather than domestic. The town centre was rebuilt as an office district, so there are large flat and shallow pitched roofs over occupied buildings, and around it run the shop parades with flats above them, each with a single flat roof covering a business at ground level and somebody’s home on top. Those roofs behave differently from a house roof. They are large, they hold water rather than shedding it, they are covered in plant, outlets and rooflights, and a failure lands on a tenant and a trading business at the same time. They also tend to be out of sight, so a covering can be well past its working life before anyone looks at it. Most of what fails on them is the detail rather than the field: the upstands, the outlets, and the joints around whatever has been fixed through the surface.

Away from the centre Croydon is largely suburban and mostly pitched. Victorian and Edwardian terraces sit closest in, interwar semi detached housing spreads through the middle of the borough, and post war estates and later development fill the edges. The coverings track the dates: natural slate and clay tile on the older stock, concrete interlocking tile on almost everything built from the 1930s onwards. Concrete tile is the one to know about here, because it does not fail the way slate does. It goes porous and loses its surface rather than slipping, so a roof can look intact from the pavement while the tiles themselves are at the end of their life, and the first real sign is often moss holding damp against a surface with nothing left to shed it.

New roofs in Croydon run from a single domestic re-cover to a full commercial installation, and the difference is mostly in the constraints rather than the trade. We set out the deck, the falls, the insulation, the ventilation and every penetration before anything is ordered, and on an occupied building we plan the sequence so the parts still in use stay usable.
Re-roofing is the point at which patching stops being economic, and on concrete tiled Croydon housing that point arrives when the tiles themselves have gone rather than when they have slipped. Stripping back shows the battens, underlay and fixings that a re-cover would simply have buried. We replace what is spent rather than laying new material over it.
On a shop parade or an office roof a leak reaches a tenant before it reaches the owner, so the useful first step is finding the actual entry point rather than sealing the visible one. Water travels across a flat deck and along a beam. We trace it from the roof and from inside the affected unit, then price the repair against what is causing it.
Flat roofing is the bulk of Croydon’s commercial stock: office decks, parade roofs over shops and flats, garages, extensions and dormer tops. Most failures are at upstands, outlets and the joints around plant or rooflights rather than in the middle of the field. We specify a warm or cold build up on what the deck and the existing detail will take, and plan access on an occupied building before quoting a date.
Croydon’s pitched stock is slate and clay tile close in and concrete interlocking further out. Concrete goes porous rather than slipping, so the judgement is whether the covering has life left in it rather than whether tiles are missing. We re-fix and re-lay what is sound, and say plainly when a covering is genuinely finished.
A green roof needs a deck rated for the loading, the correct falls and a waterproofing layer designed to sit under a growing medium. On Croydon commercial buildings that is a realistic proposition where the structure will carry it, and on domestic property it is usually garages and extensions. We survey the structure before specifying anything.
Hot melt is a monolithic waterproofing system, poured hot and bonded to the deck with no seams, which is what makes it the system for roofs carrying something on top: podium decks, terraces, balconies and green roof build ups. Croydon has more of that kind of roof than most towns nearby, over car parking, walkways and occupied space, where getting back to a failed layer later means taking up everything above it.

We are members of the National Federation of Roofing Contractors and we are CHAS accredited, with full public liability and employer’s liability insurance in place on every job and a certificate available on request. Our system warranties cover labour, materials and damage. On commercial work those documents usually have to be produced before anyone is allowed on site at all, so we provide them with the quote rather than waiting to be asked.

Domestic and commercial roofing is the same trade done under different constraints, and we carry out both ourselves rather than subcontracting the half we are less interested in:

Whether it is a Croydon flat roof over a shop and a tenant, or a concrete tiled semi that has stopped looking right, the survey costs nothing. On a commercial roof that means the whole covering, the upstands and outlets, and everything fixed through the surface; on a house it means the covering and the loft. You get what we found in writing, what we would do about it, and what the price includes. Ask us for a free, no obligation quote.

Croydon sits in south London where roofs face urban climate pressures rather than coastal ones. Air pollution and damp shaded sites accelerate moss and lichen growth on north-facing slopes, and the borough’s mature street trees mean autumn leaf fall blocks gutters and valleys quickly. Wind exposure is moderate but elevated sites on the North Downs scarp at South Croydon and Shirley take more storm load than the suburbs below. Frost damage to cracked pointing on older Victorian and Edwardian terraces is the most common winter issue. Salt-related corrosion is not a factor in Croydon.
Yes. The London Borough of Croydon has more than 25 conservation areas, including the high-profile area around Old Town, Park Hill, Addiscombe, Shirley and parts of Purley and South Croydon. Some have Article 4 Directions or listed building protections that can restrict roof shape, slope, tile material and rooflight placement. Planning consent and listed building consent are the homeowner’s responsibility. We recommend checking with the London Borough of Croydon’s planning team before any roof work begins, and we will work to whatever specification the council approves.
Croydon’s housing stock spans Victorian and Edwardian terraces across central districts, large stocks of inter-war semis and detached housing in Shirley, Purley and Coulsdon, post-war estates and modern apartment blocks throughout the borough. Pitched roofs typically use clay tile or natural slate, with concrete interlocking tiles on newer developments. Flat roofs on extensions, garages, dormers and apartment blocks are usually hot melt, EPDM or felt. Each comes with a different maintenance pattern.
After a strong westerly or south-westerly blow, look for slipped, cracked or missing slates and tiles, dislodged ridge or hip tiles, debris and leaf-fall in valley gutters, and damp patches on top-floor ceilings or chimney breasts. Lifted lead flashing around chimneys and party-wall abutments is common on older Croydon terraces. If you spot anything, get it covered or assessed before the next weather front arrives.
Both, and in Croydon commercial work is a large part of it. The town has an unusual amount of flat and shallow pitched commercial roofing: office decks, parade roofs over shops and flats, light industrial units and garage runs. Commercial roofing is the same trade under different constraints, mainly access, occupancy and paperwork. We hold the accreditation and insurance documentation that most commercial sites require before anyone is allowed onto a roof, and we provide it with the quote.
Usually yes, and it is normally the sensible way to do it. Most flat roof work on an occupied building is done in sections, so the areas in use stay usable and the covering is made watertight at the end of each stage rather than left open. What decides the sequence is access, where the plant and outlets sit, and what is underneath. We work that out at survey stage and set it out in the quote, so you know what will be disrupted and when before you commit to anything.
Often you cannot tell from the ground, and that is the trap with concrete tile. It does not usually slip or disappear the way slate does. It absorbs water, loses its surface and becomes heavier and more brittle, so a roof can read as intact from the pavement while the covering is spent. The signs worth looking for are heavy moss that keeps returning, a chalky or crumbling surface on any tile you can see closely, and damp appearing without an obvious missing tile.
Very rarely the middle. Flat roofs almost always fail at a detail: the upstand where the covering turns up against a wall or parapet, the outlet where water leaves, a joint, or the seal around anything fixed through the surface such as plant, a rooflight or a handrail. That is why a covering can look sound across the field and still leak, and why a survey has to go round the edges and the penetrations rather than walk across the middle.
Yes, in two ways. Anything fixed through a roof is a hole that has been sealed, and seals have a shorter working life than the covering, so plant and rooflights are among the commonest sources of a leak. They also affect the work itself, because a covering cannot simply be laid under a unit that is bolted down and running. Part of the survey is establishing what has to be lifted, isolated or worked around, and that belongs in the quote rather than appearing later as an extra.
By what is failing rather than by age. Repair is the right answer while the covering itself is sound and the faults are at identifiable details that can be remade. Replacement becomes the honest answer when the field of the roof has gone, when there is water trapped in the build up, when the falls are wrong so it holds water everywhere, or when it has been patched so many times that there is no original detail left to repair. We will tell you which of those we are looking at, and what led us there.
