Older High Street buildings
The 1962 county history noted nos. 115-19 and no. 86 as probably late 17th or early 18th century.
Roofers in Hounslow
Flats, terraces and the airport estates on the old heath
Hounslow grew where the Bath road leaves the Staines road, with Victorian streets round the station and airport-worker estates of houses and flats. We survey each roof closely.

Streets round the station
The area round Hounslow station filled up as the 19th century went on, with little south of it until the end.
Airport-worker estates
By 1962 estates of 204 houses and flats at Hounslow West had been built for London Airport workers.

Hounslow's blocks, flats and the planning rules
| Matter | Position at Hounslow |
|---|---|
| Planning authority | London Borough of Hounslow (unitary) |
| Building control | Hounslow's own building control service |
| Flats and permitted development | A flat is not a dwellinghouse, so house rights do not apply |
| Domestic client under CDM 2015 | An individual having work done on their own home |
| Local council tier | Hounslow, unparished area |
Hounslow is a London borough that acts as a unitary council, holding planning and running its own building control service, and it is an unparished area. From Farnborough it is 24.3 road miles, so each survey is booked in for a fixed time, and a block or terrace is surveyed roof by roof with photographs and measurements before any figure is discussed.
Why flats are different
Where a roof belongs to flats, the planning rules treat it differently. The General Permitted Development Order defines dwellinghouse so as to leave out buildings made up of flats, and a flat inside one, so the rights that attach to a house stop at the flat's front door. In practice, alterations beyond straight replacement, or that change how a building looks, need planning permission. A freeholder, managing agent or leaseholder should therefore ask the council before a new covering, a new rooflight or a plant enclosure goes on a roof.
The construction rules differ too. CDM 2015 limits the domestic client to a person having building work carried out at their home, or a relative's, away from any business. A landlord or managing agent is not within that, and when several contractors work together the Regulations require a principal designer and principal contractor to be named, while a sole contractor prepares a construction phase plan. We ask at the start who the client is.
A new rooflight in a flat roof is held to a U-value of 2.2 W/(m²·K) under Approved Document L, whereas a roof window in a pitched slope follows the window figure of 1.4 or Window Energy Rating Band B. The two are not interchangeable, so the survey notes which kind of opening a block already has before any replacement is specified.
Access, scaffold and the highway
A block roof usually needs scaffold or a safe system of access, and the position of the poles decides who needs a licence. A scaffold on the footway is licensed by the highway authority, while one on the block's own land is not. We agree the layout with the scaffolder at the survey, and we arrange any licence with the scaffolder ahead of the start date. Our commercial roofing page covers blocks and units.

A coaching road, heath gravel and airport estates
Hounslow in dates and figures from the county history
- 1833year over 200 coaches a day passed through
- 115-19High Street numbers probably late 17th or early 18th century
- 204houses and flats at Hounslow West by 1962
- 7listed buildings within 900 m of the centre
The Victoria County History's 1962 account explains Hounslow's importance: the Bath Road branches from the Staines Road here, and in 1833 over 200 coaches passed through each day. It records the soil of the old heath area as Taplow gravel. Few buildings in the town date from before the 19th century: the south side's nos. 115-19 and the north side's no. 86 on the High Street were probably late 17th or early 18th century.
Streets, then estates
The area round Hounslow station filled up as the 19th century went on, but not until the very end of the century were there any houses to speak of south of the station. Houses from those years are now well over a hundred years old, and their ridges, valleys and flashings may carry repairs of several dates. By 1962, estates of 204 houses and flats at Hounslow West had been built for London Airport workers by the British Airways Staff Housing Society, which adds a mid-20th-century layer to the town's housing.
Whatever the covering, estates built together age together: the same fixings, the same underlay and the same gutter brackets reach the end of their lives at similar times. We therefore look for the common failure points across a block or a street, without assuming that any of them has failed.

Flat roofs on blocks and extensions have their own published costs. In HomeBuilding's guide the supply-only costs per square metre are £65 for felt, £105 for EPDM, £110 for GRP and £170 for lead. These are materials only, so they say little about the price of a finished roof, which depends on area, falls, access and edge details. BS 6229:2025 sets a minimum finished fall of 1:80 for flexible membranes, and the roof should be designed for 1:40, according to IKO. Our flat roofing page explains the choice of covering.
Lifespans differ by covering and by source. HomeBuilding gives EPDM 25-30 years and Less gives 30 to 50 years, so the guides disagree; for felt they give 10-15 and 10 to 20 years. Each is a typical range, never a promise, and the survey judges the actual membrane by its seams, its upstands and its falls.

St Stephen's conservation area and Bell Road
| Designation | At Hounslow | For roof work |
|---|---|---|
| Conservation area | St Stephen's | Changes to the look checked with Hounslow |
| Grade II listed | Bell Road Methodist Church (NHLE 1096907) | The Methodist Church's own system |
| Grade II listed | 1 and 3 Whitton Road (NHLE 1189614) | Listed building consent |
| Grade II listed | 103 Pears Road (NHLE 1260971) | Listed building consent |
| Grade II listed | 44 to 50 Bath Road (NHLE 1079602) | Listed building consent |
The national dataset places the St Stephen's conservation area in Hounslow, and the borough's own map is the document that settles whether a given block or house is inside it. Anything that changes the street-facing look of a roof should go to Hounslow's planners before pricing. Our planning permission for roof work guide covers what to ask, and for flats the answer is more often yes.
Access to a block roof is its own question. Edge protection, roof hatches and anchor points are checked for condition, because a roof that cannot be reached safely is a roof that goes unmaintained, and unmaintained gutters and outlets are where block leaks begin.
Listed buildings in the town
Historic England lists 1 and 3 Whitton Road at Grade II from 21 May 1973, and 103 Pears Road and 44 to 50 Bath Road at the same grade. Bell Road Methodist Church is Grade II, listed on 18 June 1990, and the Richmond and Hounslow Methodist circuit lists it among its churches, with the circuit office there. The ecclesiastical exemption therefore applies: a Methodist church in use is approved within the Methodist Church's own procedures and not through the council's listed building consent. The list counts seven listed buildings within 900 m of the centre, so each address is looked up before pricing.
Listed building consent from the council is the route for changing a listed house's or shop's character, and it is separate from Building Regulations. Photographs from the survey go with the application, and no roof work starts before consent.
Parapets, valleys and lead
Where shops front the High Street, one roof may serve flats above and a unit below, so a leak can cross tenancies. We trace water to its source and write down who it affects, which saves arguments later.

Where an older terrace finishes in a parapet and valley gutter, the lead lining is hidden from the street. A parapet gutter takes water from two slopes, so a single failed joint can wet a ceiling far below. Royston's brochure sets heavier codes for parapet and box gutters than for soakers, and MyJobQuote's 80-year figure for lead flashing is a minimum. Our lead roofing and lead work page covers how such gutters are renewed, and we record their length and falls before any price is written.
Flats, flat-roof costs and the High Street: Hounslow questions
How is a communal flat roof on a Hounslow block surveyed?
We take levels along the fall, photograph every outlet, upstand and seam, and record the access and edge protection. For a block the client is usually a freeholder or managing agent, so we ask who that is at the start. The written findings say whether the roof needs a patch, a part re-cover or replacement, and why.
Can a Hounslow leaseholder re-cover a block roof without planning permission?
A straight like-for-like replacement may not need it, but a flat is not a dwellinghouse, so a house's rights do not apply, and anything that changes how the building looks does. The freeholder or managing agent normally holds the roof, so ask them first, then Hounslow's planners about any alteration.
What do flat-roof coverings cost to supply, by published guides?
HomeBuilding's supply-only figures, per square metre, are £65 for felt, £105 for EPDM, £110 for GRP and £170 for lead. They cover materials only, not labour, access or edge details, and none is a quotation. A finished roof's price depends on area, falls and access, and ours is a single total set once the survey is done, with the access and the scaffold inside it.
Does Bell Road Methodist Church need listed building consent for roof work?
Not for a church in use. Bell Road Methodist Church is listed Grade II, but a Methodist church in use is approved within its own denominational procedures, not by the council. Listed buildings that are not churches, such as 44 to 50 Bath Road, go through listed building consent, and we check which applies before any roof work is priced or booked.
