Roofs in the Croydon district once home to a military college.
Addiscombe was once called Edgecombe, a tithing of the manor of Croydon, before the East India Company's college arrived. We survey its roofs house by house and price in writing.
Part of Addiscombe lies in the East India Estate conservation area. Inside it, anything that changes how a roof looks goes to Croydon's planning team first, while a like-for-like repair stays simple to arrange.
Terraced homes with tiled roofs
St Mildred's church and Havelock Hall are both Grade II listed. Listed status means consent for works that affect character, so ask the council before attempting anything beyond plain maintenance.
Pitched roof on an older building
Streets here pack houses and flats close together. Where roofs share a ridge, valley or party line, a leak on one side can start next door, so we follow the water along the whole run.

Addiscombe roof notes
Three short chapters on how Addiscombe came about, how its conservation area and listed buildings shape roof work, and what a Croydon scaffold licence involves.
Stage 01 · Background
Addiscombe was formerly called Edgecombe, one of the tithings of the manor of Croydon, and later hosted a military college.
The Victoria County History says Addiscombe, once called Edgecombe, was one of the tithings of the manor of Croydon. It later became the home of the East India Company's military college, and the novelist Thackeray lived there with his mother and stepfather, a superintendent of the college, after they returned from India in 1821. St Mary Magdalene's church followed in 1878, and a parish was formed for it the next year. For a roofer the history matters for one reason: a district with layers like these holds buildings of many ages, and no roof here should be judged from its neighbour.
By looking, not by postcode. From the pavement we note the tile profile, the pitch, the state of the ridge and how the verges are finished. In the loft we check the underlay, the battens and the rafters. Photos of each go to you, so the findings stay on the record whoever reads them later. Age is only a guide. Marley puts concrete tiles at around 60 years and adds that the figure is not a warranty, while clay tiles carry a 60 year minimum from the Building Research Establishment. The parts around the tile often need attention first: ridge bedding, nails, underlay at the eaves and the gutters.
On an Addiscombe survey
Access and shared lines. Neighbouring roofs can share a ridge, a valley or a party line, and water that comes in at one house can track along a rafter into the next. We follow the full run before pricing, so the repair does not stop at a boundary line the water ignores. On a block, the freeholder or managing agent may need to approve the work, and our roof replacement page covers how we plan a full re-roof around neighbours, shared paths and bin stores. Small flat roofs over bay windows, porches or extensions get a look as well, because a blocked outlet or split seam there can soak a room that seems far from the roof. Our flat roofing page sets out what we look for, from ponding to failed edge trims.
On terraced streets with limited room, the order of work matters too. Scaffold goes up on the street side only when the alternative is worse, materials are lifted in loads rather than left on the pavement, and rubbish leaves in covered containers. Neighbours hear the dates before they see the poles, since an hour of warning does more good than an apology later.
Stage 02 · Old buildings
Part of Addiscombe lies in the East India Estate conservation area, and listed buildings close by show why consent questions come before the roof does.
The planning.data.gov.uk dataset records part of Addiscombe within the East India Estate conservation area, which means some streets carry the extra planning care that comes with that status and others do not. Two listed buildings sit in the district: the Church of St Mildred, Addiscombe, listed Grade II on 26 May 2023, and Havelock Hall, also Grade II. A house in the district may be inside the conservation area, outside it, or next to a listed building, and only the council's maps say which.
A like-for-like repair that leaves the roof looking as it did is the simple case, whether or not the house is inside the conservation area. The questions begin when the appearance moves: a different covering, new roof windows, an altered chimney or a changed ridge. For those, ask the London Borough of Croydon's planning team before committing, and tell us what comes back so the written price reflects it. Flats are treated differently from houses in the planning rules, so if you live in a flat, ask before assuming anything. Our planning permission for roof work post gives the starting points.
Consent words, plainly put
Ask the council before the scaffold goes up, not after the tiles come off.
Listed status attaches to the building, not the street, so your own roof is only affected if your house is itself listed. Still, working beside a listed building means more care over access, scaffold, dust and debris, and we plan with that in mind. If your own house is listed, works that affect its character need listed building consent, and the council's conservation team is the place to start. We will not book a start date for anything beyond maintenance until you hold that answer.
Beyond consent, we check how a roof is held together at the points that fail in any district. Ridges and hips bedded in mortar are one: the 2014 revision of BS 5534 expects mechanical fixings too, and Marley says bedded fittings should not depend on mortar alone. Verge edges and the flashings around chimneys are the others. Where a ridge needs rebedding, we say whether dry-fix would also suit the roof and show you why in the photos, so the decision stays with you.
Stage 03 · Permissions
The London Borough of Croydon handles planning, building control and highway licences, and its scaffold terms are worth knowing before you book.
Croydon is a London borough, so there is no county council in between: the borough is planning authority, building control body and highway authority, with the Greater London Authority above it. That keeps the paperwork in one place, but its scaffold terms deserve a read before a job is booked.
Croydon's pages give the minimum period for a scaffold licence as one month, say the licence is only issued once a site visit has taken place, and put the charge at £488 per 4 weeks per elevation, or £610 where the scaffold runs over 10m in length. A refundable bond deposit of £50 per square metre of enclosed highway is also required. A renewal has to be made at least 7 days before the licence expires. Croydon does not publish a lead time for a first application, so the licence is agreed jointly with the scaffolding firm and the start date is fixed only after they confirm it. On private land, Croydon says you do not need a licence or consent, though a parking suspension may still be needed. A pavement scaffold adds to the total, so ask any firm quoting you if the figure takes in scaffolding and VAT.
Croydon scaffold licence
The Planning Portal sets the thresholds at 25 per cent of the building envelope and 50 per cent of the roof: affecting less than both normally means no application. A new covering 15 per cent heavier or more does need approval, and the portal advises taking a structural engineer's or surveyor's view before you start. Croydon's building control team can tell you what applies to your job. Our pitched roofing page explains how tiles, battens and underlay are repaired or replaced without changing the weight of the roof.
Bats and nesting birds are on the checklist before work begins. Government guidance treats all bats and their roosts as fully protected and counts roof repair or replacement among the activities that can affect them, so any sign in the survey brings the job to a pause while we talk it over. Your first move is a photograph of the slope, flat roof or gutter that worries you, with your Addiscombe postcode, and the conservation area map gets checked against your address before we go further.
It can, where roofs share a ridge, valley or party line, because water runs along rafters and surfaces before it drips. We follow the stain back along the whole run in the loft, photograph where it enters and tell you plainly if the fault sits on the neighbouring side. You then have evidence to show them, and your own side is made sound.
Matching tiles laid the same way rarely raise a question. A different tile is another matter if your home falls within the East India Estate conservation area, which covers only part of Addiscombe, so check the council's map first. Ask the London Borough of Croydon's planning team before changing a covering, roof window or chimney, and tell us the answer before we price.
Croydon's terms call for a refundable bond deposit of £50 per square metre of enclosed highway alongside the licence charge. The bond comes back under the licence conditions. It is one reason a pavement scaffold adds to the total, so see if any quote you receive covers the scaffolding. A drive or garden with room avoids the licence entirely.
We need access to the loft, so someone should be there or arrange a key. We photograph rafters, underlay, battens and any stains, then show you the pictures at the end. If you rent, or own a flat, tell us who holds the freehold, because the managing agent may need to approve work on the roof.
A photograph of the slope, flat roof or gutter you are worried about, with your Addiscombe postcode, gets a survey date booked.
