Flat Roof Repairs In West Wickham
Is a shaded flat roof at your West Wickham house staying wet for days?
Repairs to extension, garage, porch and bay roofs on interwar semis and detached houses across West Wickham and Coney Hall
Take a typical interwar semi off Station Road or Hayes Lane, or a 1930s house on the Coney Hall estate, and you will usually find more flat roof than you expected. There is the rear extension, perhaps a garage or a porch, and over the ground-floor bay a small flat top that sits directly below a run of tile hanging. The ground rises towards the Kent border and the residential roads are full of mature trees, so a lot of these roofs spend most of the day in shade. Leaves and moss land on them, the outlet clogs, and the surface never quite dries. That is the starting point for most of the West Wickham flat roof leaks we are asked about.
Flat Roof Repairs quote in West Wickham
Four details and somebody will come and look at it. There is no charge for the visit, no obligation afterwards, and if the answer is that your roof is fine, that is what you will be told.
The people behind it
A family firm, two names, one job
Flat roof repairs are often small and fiddly, and it helps to know exactly who is responsible. Here that is John and Mark, a pair of brothers running a family firm, who manage the team and see each job through together.
Because both of them know your job, you are rarely left waiting for one person to come back to you. Ring either and you will usually get an answer. Customers often say that working with them is refreshing.

Four flat roof warning signs common in West Wickham
Shade, trees and tile-hung walls each leave a recognisable trace. Check for these, in roughly this order.
Green growth or a dark film across the surface
The roof is staying damp because it gets little sun. Moss and algae hold water against the covering, and their debris drifts towards the outlet and blocks it.
Water still lying near the outlet two or three days after rain
The outlet or the gutter at the edge is choked with leaves and moss. Water backs up, finds the weakest lap in the covering and works under it.
Damp at the top of the bay window inside
The flat roof over the bay meets the brickwork, and often a band of hanging tiles, right above it. Water running off the tile hanging lands on that joint. When the seal there fails, it goes straight in.
Soft spots underfoot on the extension roof
The boards under the covering have been wet for some time. On a shaded roof they dry very slowly, so a small leak can rot a larger area than you would guess.
What we do differently on a West Wickham flat roof
Outlets and gutters cleared first
Before deciding anything, we clear the debris and watch where the water goes. Sometimes the blockage was the whole problem and the covering is fine.
The bay roof checked with the tile hanging
A leak over a bay can come from the flat top, its flashing, or the hanging tiles above. We check all three together rather than treating them as separate jobs.
Coverings chosen for shade
On a roof that rarely dries, a single bonded sheet with few joints gives water fewer places to sit. We explain which covering suits your roof and why.
Wet boards replaced, not covered over
We lift a section and test the deck. A new membrane laid on damp timber shuts the moisture in and the rot carries on underneath.
Bromley's rules applied, not Croydon's
If anything about the work needs an application or building control, it goes to the London Borough of Bromley. We tell you clearly whether it does.
Ten year workmanship guarantee
Handed to you in writing when the repair is finished, with photographs of the completed roof.
Shade, trees and tile hanging: why West Wickham flat roofs fail
Most flat roofs fail through water that stays where it should not. In West Wickham the main reason it stays is shade. Street trees, big garden trees and the rising ground towards Kent, keep plenty of rear extensions and north-facing garage roofs out of direct sun for long stretches. A surface that never dries gives moss somewhere to grow. The moss holds water against the covering, sheds into the outlet and slowly builds a dam. By the time a stain appears on the ceiling, the problem has often been building for a couple of seasons.
The houses add a second factor. Many of the interwar semis and detached houses here, including a good number on the Coney Hall estate, have tile-hung upper walls. When those walls sit above a flat roof, as they often do over a bay, every drop that runs down the hanging tiles lands on the junction below. If the flashing at that point has cracked, or the hanging tiles have slipped and opened a gap, the flat roof gets the blame for a leak that started higher up the wall.
"On the West Wickham flat roofs we look at, a blocked outlet and a mossed-up surface turn up far more often than a covering that has simply worn out."

The six steps of a West Wickham flat roof repair
Describe what you have noticed
Where the damp is, how long it has been there, and whether the roof is under trees. A photo from an upstairs window helps us plan.
Clear and inspect, free
We clear the outlet and edge, then check the covering, the upstands, the bay junction and any tile hanging that drains onto the roof.
Test the deck
We walk the roof for soft spots and take a moisture reading. If it is doubtful, a small cut-out shows whether the boards are still sound.
Written price, with options
A targeted repair and a full re-cover are priced separately where both are reasonable. Work to the tile hanging, if needed, has its own line.
Carry out the repair
Wet boards replaced, failed covering stripped back, upstands and flashings renewed, and the outlet set so water leaves the roof without pooling.
Check, photograph, hand over
We run water to the outlet where safe, photograph the finished roof and give you the ten year guarantee, plus a note on keeping the outlet clear.
The 10 year guarantee, and why it is safe to offer
Promising a roof will stay dry is easy. What counts is what happens if it does not. Work booked through Roof Repairs Croydon carries a 10 year workmanship guarantee, on paper, handed to you on the day and written in language you can actually read. The slates, tiles, lead, mortar, membranes and rainwater goods carry their own manufacturer cover on top of that. It varies by product, so you get told which cover applies to your job rather than one headline number that would be wrong on most of them.
Here is the reason a guarantee like that is not a risk. Repairs come back for one reason above all others: the fault was never found in the first place. Somebody went up, saw a stain on the ceiling below, mended whatever looked worst directly above it, and left. Water does not cooperate with that approach. It lands on a slate, runs under it, drops onto a rafter and travels along the rafter before it finds anywhere to fall. On a wide hipped roof in Sanderstead or Shirley that can be five metres from where it came in.
Find the entry point and the repair holds for years. Miss it and no amount of guarantee wording helps anybody. That is why the survey happens before the price, and it is why, if the same water finds its way back into your house inside the guarantee period, putting it right costs you nothing.

Three things to ask before a West Wickham flat roof is quoted
Did they clear the outlet before quoting?
A roofer who prices a new covering without clearing the debris and watching the drainage may be quoting for a problem you do not have.
Did they look above the roof?
Over a bay, the hanging tiles and the flashing above matter as much as the flat surface. A sound quote mentions both.
Do they know which council you are in?
West Wickham is Bromley, not Croydon. If a quote refers you to Croydon for anything, that is a sign they have not checked.
Repair it or re-cover it?
On a shaded West Wickham roof the answer usually comes down to how wet the deck is. Here is how the two compare on a typical extension or garage.
| Comparison point | Repair | Re-cover |
|---|---|---|
| Right when | Deck dry, one fault found | Deck damp or surface tired |
| Time | Usually a day or less | Usually one to three days |
| Moss and pooling | Outlet cleared and reset | Falls corrected if needed |
| Boards | Odd ones swapped | All soft boards renewed |
| Cost | Lower | Higher, with a longer life |
| Building regs | Not normally | Possible if over 25% renewed |
Chimney or flat roof?
A stack on an interwar semi can drip water into the same back bedroom as a leaking extension, so the two get mixed up. If you suspect the chimney, see our page on chimney repairs in West Wickham. We can check both in one visit.
Flat roof repair costs in West Wickham
Clearing an outlet and resealing a bay roof costs a fraction of re-covering a garage. These three factors decide where your job falls.
Shade and how long the roof has been wet
Under the big trees round Hayes Lane and up towards Corkscrew Hill, a shaded roof can stay damp for years before it shows inside. The longer that has gone on, the more boards are likely to need replacing.
Whether tile hanging is involved
On 1930s houses in Coney Hall and off Station Road, the leak over a bay may involve the hanging tiles above it. Refixing those adds labour and sometimes a tower.
Size and access
A porch top is a few hours. A garage or rear extension reached through a side passage takes longer, and skips or access equipment are priced as separate items.
Flat Roof Repairs in West Wickham: questions
Who do I ask about planning for a flat roof in West Wickham?
The London Borough of Bromley. Because it sits right next to Shirley and Addington it gets mistaken for Croydon all the time, yet planning decisions and building control here both rest with Bromley. Re-covering a flat roof like for like does not usually need planning permission. If more than a quarter of a roof is renewed, building regulations may require the insulation to meet current standards, and that would go through Bromley's building control.
Why does moss keep coming back on my flat roof?
Because the roof is in shade and stays damp. Trees along the road or in the garden block the sun, and moss grows wherever a surface stays wet. We clear it by hand and can treat it, but the lasting fix is keeping the outlet clear and, where you are allowed to, cutting back overhanging branches.
My West Wickham bay window leaks at the top. Is that the flat roof?
Possibly, but check what is above it first. On many 1930s houses here the small flat roof over the bay sits below a band of tile hanging. The leak can come from the flat covering, the flashing where it meets the wall, or slipped hanging tiles feeding water behind it. We check all three.
Is it worth re-covering an old felt roof under trees, or just repairing it?
It depends on the deck. If the boards are dry and there is one clear fault, a repair is fine. If the boards are soft or the felt is cracked all over, a re-cover with a single bonded membrane usually lasts longer in shade. We test the deck before advising.
Do you cover Coney Hall and the roads near Wickham Court?
Yes. We work across West Wickham, including Coney Hall, Wickham Court, Station Road, Hayes Lane and Corkscrew Hill. It is around 15 minutes from our base.
What Croydon homeowners say
From roads across the borough, once the ladders had gone.
"Damp patch on our landing ceiling for about three years. Two roofers had been out and both mended the tiles directly above it, and neither made the slightest difference. This chap spent twenty minutes in the loft with a torch before he even went outside, then showed me a photo of a split in the lead in the valley about four metres away from the stain. Fixed it in a morning. Three winters on and nothing."
"Water was coming down the front bedroom wall every time it rained hard and I had convinced myself the roof was finished. It was the gutter. Half of it had dropped so the water was sitting in the middle and going over the front rather than down the pipe. He reset the brackets and cleared the gully, charged me a fraction of what I had budgeted for, and told me the roof itself had years left. Could easily have sold me a new one."
"Ours is in the Chatsworth Road conservation area and I had no idea the rules on roof work here are stricter than the rest of Croydon. He knew straight away, explained what I could and could not do without an application, and did the repair in matching slate. That saved me a very awkward conversation with the council later on."
"Lost most of the ridge tiles along the back in a February gale. Rang in the morning, sheeted the same afternoon so the weather could not get in, came back the following week when it was dry and rebedded the whole ridge properly. Sent me photos of everything for the insurance without me even asking. The bill was exactly what the quote said it would be."
"Gutters had been overflowing under the trees for years and the fascia behind them had gone soft. What I appreciated was that he explained why the timber had rotted rather than just quoting to replace it, and pointed out the new soffits needed vents or I would end up with condensation in the loft instead. Nobody had ever mentioned that to me before."
Had us out to your roof?
Two minutes writing a review does more for a small local firm than any amount of advertising, and it helps the next person in Croydon work out who to ring.
