Hanwell: your questions answered
Does a conservation area affect roof work in Hanwell?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you look at commercial flat roofs near Hanwell, like hotels?
Yes, commercial buildings, hotels included, are part of the work. Access to the roof is sorted out with whoever manages the building before the day.
How long does the survey take?
It typically takes roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. The report follows by email.
How soon will I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. Reports are sent by email.
Can you survey in bad weather?
It depends on the weather and the survey. Strong wind or a downpour can make access unsafe and ground a drone, and we’d agree another day.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first, with the building owner or managing agent. Tell us about it when you book and we’ll explain what’s needed.
How much does a flat roof survey cost in Hanwell?
Our price is from £150, including VAT. The final figure depends on the roof and the package you choose, confirmed before anything is booked.
Flat roof survey in Hanwell
Water through a flat roof does not always come in where the stain is. It can run along the deck from a split, an open lap or a failed upstand some distance away. Our survey covers the whole roof, not just the part above the mark, and photograph anything that could let water in. Whoever carries out the work then has a clear starting point. If you’ve noticed failed seals around rooflight kerbs and loose or cracked edge trims, a survey will tell you what’s going on, whatever the roof.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. Which one is on a roof in Hanwell shapes how it’s checked. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
Pictures do a lot of the work in our reports, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Roof by roof
Mastic asphalt
Mastic asphalt is a heavy, seamless covering often found on older blocks, balconies and commercial roofs. The survey checks for crazing, cracking, blistering and splits where the asphalt turns up the walls.
Single-ply membranes
Plant, fixings and foot traffic can all damage a single-ply roof. Any tears, punctures or loose membrane are recorded with photos.
Flat and commercial roofs around Hanwell
There are several hotels within about a mile and a half of Hanwell. If you look after one, a leak through a flat roof can put a room out of use. Pitzhanger Manor, about 1.3 miles east, is one of the historic houses in the wider area around Hanwell. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
Landlords with a home close to Hanwell station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you look after a shop, office or commercial unit, for instance near Treaty Centre, a flat roof over a business is out of sight and out of mind until it leaks. A roof leak in a hotel or guest house around Hanwell means lost rooms as well as repairs.

The survey, step by step
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Many London properties are flats or terraces with no side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, tell us when booking.
- We start with the address and, on larger roofs, the roof area and access.
- Inside, we look for signs of water under the roof where we can reach.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- You get a report setting out the condition and our recommendations, in order of urgency.
Before we arrive
- If it is not your property yet, arrange access through the agent
- If the roof is shared, arrange access with whoever manages the building
- Keep pets in another room

DIY checks: what’s safe
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
A DIY look is useful, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
Landlord and commercial surveys in Hanwell
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out by urgency where it matters, which helps with budgets and planning.
Buyers’ agents can book surveys on behalf of their clients. Reports are emailed, so they’re easy to pass on.
Practical tips
These tips come from what we see on roofs every week, before and after a survey:
- Watch the ceilings below the flat roof for stains
- Look for standing water a day after rain
- Have the roof looked at again after a severe storm
- Treat rooflights and old sheeting as fragile
For landlords and building managers, the report is a dated record of the roof’s condition. It helps when planning maintenance budgets, and it gives a baseline to compare against next time.
Book a survey every few years, and again after new fixings, units or rooflights go in. You will spot changes early and have a record to look back on.
