About our new roof snagging in Harmondsworth
A new roof needs to breathe. Where vents have been fitted at the ridge or eaves, we check them, and check the roof space for signs of condensation. What we see goes in the report. Missing or blocked ventilation can lead to condensation over time, which is easier to put right while the roofer is still involved. We record what we see. We survey ridges and verges, replacement roofs and flashings and valleys, and the problems we are asked to look at most are cracked or slipped new tiles or slates and offcuts and broken tiles left behind.
London terraces and converted houses frequently share a roof line, chimney stacks and gutters with the house next door. That matters for anyone buying in Harmondsworth or checking a new roof there: only the parts we’re given access to and can see safely are inspected. For a flat, the lease typically says who looks after the roof.
Where we can’t see part of the new roof, the report says so. That way, it’s clear what was covered and what wasn’t, and what we’d suggest next.

Harmondsworth homes and their roofs
If your home is older, it’s worth knowing whether it is listed or in a conservation area before planning roof work. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area. In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. For a purchase or a newly finished roof, the materials decide which details matter most.
For a London address like Harmondsworth, it is useful to know about controlled parking before the day, along with any off-street space. Take an older house close to Church of St Mary: ask the seller about past roof repairs, because older roofs often have patched valleys, replaced slates and reset ridges.
Harmondsworth is about 1 mile south-west of West Drayton, in Greater London. We survey roofs in Harmondsworth and the rest of Greater London, as part of our work across London and South East England. We cover towns and villages across Greater London, from the larger towns to small villages. For surveys nearby, see our London page.

Practical tips
Most of what helps is simple and safe from the ground. Our suggestions:
- Send the snagging report to your roofer
- Check ceilings and the loft after heavy rain
- Book snagging before the final payment
- Tell your roofer the work will be inspected
Report times depend on the package: within 48 hours for Basic, 24–48 hours for Standard and the same day for Premium. If a payment is due soon, choose the package that fits.
Keep paperwork for the new roof together. The report belongs with them.
Landlords, agents and block managers in Harmondsworth
Letting agents can arrange access with tenants, at a time agreed ahead of time. Surveys run on weekdays, Saturdays and Sundays, which can make access easier.
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work.
Checking the roof from the ground
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
It is useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry.
How it works
Once we have finished looking, we write up our findings as a written report with photos, sent to you by email. As for time on site, it typically takes roughly 1–2 hours at a typical home, with bigger or more complicated roofs taking longer. Surveys in Harmondsworth can be booked for any day of the week. London parking is often by permit or pay-and-display, so it helps to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- First, we note any deadlines and concerns.
- The roof is inspected from ground level, vantage points and the roof where safe.
- We work through ridges, verges, valleys and flashings.
- We check the gutters, lower roofs and walls for debris or damage.
- We send a written report you can pass on.
How to prepare
- Keep pets in another room
- Have keys ready for side gates, garages or roof access doors
- Agree roof access with the managing agent if it is shared
Getting a price
If you have photos of the roof, send them over. Pictures from the ground or a window are fine, and please do not climb up for a closer look. To get started, phone 07833 053749 or email us.

Signs you need new roof snagging in Harmondsworth
Roofers do not always clear every gutter and lower roof. Offcuts and broken pieces often end up in the gutters or damage lower roofs.
Things that frequently lead to a survey include:
- Loose or badly finished ridge tiles
- Broken coverings left on a new roof
- Gutters or fascias damaged during the job
- Gutters blocked by building debris
Landlords with a home close to Heathrow Terminal 5 Rail station may find that the roof is worth checking before you add another property to a portfolio or pay a roofer in full.

- Whether they hold professional indemnity and public liability insurance
- Whether the price includes VAT
- Whether any drone flown is registered with the CAA
