Coulsdon is almost all inter war and post war: the 1930s suburbs that spread out from the railway, and the estates after. High, exposed, and windy, which is hard on ridges and chimneys.

Coulsdon’s roofs
Coulsdon grew up around its railway, and the roads near Coulsdon Town and Coulsdon South stations hold its older housing, Edwardian and from between the wars: bay fronted semis and short terraces under clay plain tile, with slate on a few of the earliest. Most have since had a loft conversion, and the dormer on the back slope is where a lot of their leaks begin.
The roads that climb away from Chipstead Valley Road are lined with 1930s semis and detached houses cut into the hillside. Clay and early concrete tiles on hips and gables, and on the downhill side a tall gable end whose verge takes the full force of the weather.
On the higher ground eastward, Old Coulsdon keeps its village core around Bradmore Green and the medieval church, with older houses and cottages under clay and slate. Larger houses from after the war surround it on big plots, with roofs of several hips, valleys and dormers.
Towards Coulsdon Common, Kenley and the edge of Farthing Downs the houses stand high with little to break the wind. Bedded ridges and verges loosen first, then the tiles along the eaves. On roofs this exposed we usually suggest dry fixed ridges and verges, so every tile is held by a fixing instead of mortar.
The homes on the former Cane Hill hospital site are new builds, so their roofs are young. Problems there tend to be a slipped tile, a blocked gutter or a storm lifting something loose, rather than wear.
The estates built after the war, around Coulsdon and out towards Woodmansterne, are concrete interlocking tile laid over sarking felt that has since perished. The tiles are usually fit to reuse, so lifting them, laying breathable membrane on fresh battens and refixing the same tiles often makes more sense than buying new.
Walk any road in Coulsdon and you will count dormers. Their flat tops, the lead cheeks at their sides and the joint with the main roof are the weak points, and felt dormer tops put on around the turn of the century are now due to be covered again.
Coulsdon is about ten miles from the office, over the Downs by way of Epsom and Banstead, and sits at the eastern edge of the area we cover. It is in the London Borough of Croydon, so scaffold standing on a pavement needs the borough's licence, which we apply for. On the steeper roads the scaffold is stepped, and the quote allows for it.
What we are called to in Coulsdon
What we do in Coulsdon

Height brings wind damage: a ridge lifted, a verge stripped, a run of tiles off the eaves. We get the roof watertight, then fix the cause so the same tiles do not come off in the next gale.

Inter war houses here are clay plain tile, the estates concrete interlocking. Both can be matched, and where the felt and battens have had it we strip, re-felt and lay the sound tiles back.

Stacks up here weather fastest on the face that takes the wind. Open joints are repointed, the flaunching renewed, new lead dressed at the roof line, and the top courses rebuilt where the brick has gone.

Roof repairs in Coulsdon
High ground and inter war houses give Coulsdon its own set of faults. These six come up again and again.

Likely cause
On exposed ridges the mortar bedding fails first, and once one tile goes, the gale lifts its neighbour. We put the ridge back, either re-bedded or on a dry fix system that screws or clips each tile down so it no longer relies on mortar.

Roof Repairs in Coulsdon
Likely cause
Along a gable, the edge tiles were pointed with mortar that years of weather on the slopes have washed out. Loose verge tiles then lift in a storm. A dry verge system caps the edge and clamps each tile in place.
Usually the job is
Tiled Roofing in Coulsdon
Likely cause
Usually the dormer: a split in its flat top, open joints in the lead along its sides, or the flashing where it meets the main roof. We find which and repair it, or cover the dormer top again if the old felt is finished.
Usually the job is
Flat Roofing in Coulsdon
Likely cause
Up here a stack takes driven rain on one face, and water soaks in through open mortar joints or behind tired flashings. Repointing, new flaunching round the pots and fresh lead at the roof line usually put it right.
Usually the job is
Chimney Repairs in Coulsdon
Likely cause
Under the concrete tiles of the post war houses, the original felt has perished, so rain driven by the wind gets past the tile laps. With the tiles lifted off, breathable membrane and new battens go down, and the same tiles are relaid.
Usually the job is
Roof Repairs in Coulsdon
Likely cause
On Old Coulsdon's bigger houses water most often gets in at a valley between two wings, or where an extension meets the original roof, and travels along the timbers before showing. Following it back from the loft and on the roof, we find the failed lead and renew it.

Call 01372 540 258, or 07513 397 799 at any hour for a live leak. A photo of the damage, even from the pavement, tells us what to bring.
We come over the Downs and get up on the roof and into the loft, looking hardest at ridges, verges and stacks, the parts the wind works on.
You get an itemised written quote with the scaffold included. If a repair will hold, you will not be quoted for more.
Exposed ridges and verges fixed mechanically, each stage photographed, and the garden and drive left clear when we go.

Coulsdon questions
More about Coulsdon roofs below. For anything else, call 01372 540 258 and ask a roofer.
Height and wind. Mortar bedding on a ridge that has faced weather off the Downs for decades crumbles away. Replacement ridges are dry fixed, clipped or screwed down, so they cannot blow out the same way again.
Yes, along with Old Coulsdon, Woodmansterne, Hooley and Banstead.
Around twenty five minutes from Leatherhead. A leak is usually seen the same or the next day, and 07513 397 799 is on 24 hours.
It is a run of interlocking caps that fixes the tiles along a gable edge mechanically instead of with mortar. On exposed Coulsdon roofs, where pointed verges keep washing out, it is usually the better long term repair.
Usually. The felt is stripped from the dormer top, the deck underneath checked, and a new covering laid, often GRP, with fresh lead on the cheeks if the old has split.
For a like for like repair, normally none. Around Bradmore Green some of the village is protected, and changing a roof's material there may require consent, so we confirm your house's position with Croydon before quoting.
Yes. On a slope the scaffold is stepped to suit the ground, and if it needs pavement space we get Croydon's licence first. All of that is in the written price.
If they are sound, yes. On many post war Coulsdon roofs the tiles come off, the felt and battens are renewed, and the originals go back on, keeping the look and saving the cost of new ones.
Yes. A cowl or vented cap keeps rain and birds out of a disused flue without sealing it completely, and cracked pots are replaced with new flaunching round them.
