How new roof snagging works in Harlington
We carry out new roof snagging in Harlington and across London and the South East. A visit usually takes about 1–2 hours for most homes, depending on how much new work there is to check. Everything visible from safe vantage points is checked, and by drone where it is applicable. You then get a written report with photos. We inspect on weekdays and at weekends. Typical surveys look at cracked mortar at the ridge or hips and tiles or slates sitting out of line, across new flat roofs, replacement roofs and ridges and verges.
In a London terrace or conversion, the roof frequently joins the neighbours’ roofs and shares their stacks and gutters. That matters for anyone buying in Harlington or checking a new roof there: we inspect what we’re given access to and can see safely, which may not include a neighbour’s side. For a flat, the lease typically says who looks after the roof.
After the visit, you get a report with photos, emailed to you. It sets out the condition of the new roof, any defects and our written recommendations.

When to book a survey in Harlington
Owners frequently get in touch when the finish looks uneven or a leak appears. Others want an independent check as a matter of course before the job is closed.
Most people get in touch after spotting something like this:
- Loose or badly finished ridge tiles
- Loose flashings at walls or chimneys
- Untidy or loose verge details
- Broken coverings left on a new roof
Controlled parking zones are common in London, so mention any permit rules for Harlington.
Questions to ask before booking
- What exactly goes into their report
- When you will get the report
- What they won’t be able to tell you
- What experience they bring
How the survey works
Once we have finished looking, we write up our findings in a report with photos, sent to you by email. As for time on site, it normally takes an hour or two for a house, and longer for a large or complex roof. In Harlington, as in much of London, plenty of properties are flats or terraces without side access, so the back of the roof is often 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, let us know when booking.
- First, you tell us what the roofer did and any concerns you have.
- The coverings, ridges, hips and verges are checked as far as can safely be seen.
- We check valleys, flashings and gutters, and the underlay at the eaves where it is visible.
- The loft space is checked where safe, along with any mess or damage left after the work.
- The snags are written up with photos for you to share with your roofer.
Before we arrive
- Tell us about parking before the day
- Make sure pets are kept safely away
- Tell us about any leaks, stains or damp patches you know of

How we price new roof snagging
When we price a survey, we consider:
- Roof area
- The height of the building and how the roof can be seen safely
- If the survey needs thermal imaging or a drone
- Which survey package you book
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all inc. VAT. The price for your roof depends on its size, access and what you’d like to know.
What we need to know
If you can, have these to hand when you get in touch:
- Why you want a survey: buying, a leak, a storm or new work
- Any stains, drips or damp patches you’ve seen indoors
- The property’s address and postcode
- The type of building and roof, such as pitched or flat
Most bookings start with a short call: phone 07833 053749 or use the contact form, and we’ll ask about the building and what you need. The price is agreed before a date is set.
Before and after the survey
You don’t need to be a roofer to help. What helps most:
- Check the roof before you pay in full
- Look for new stains after a downpour
- Look for marks or cracks left by the work
- Check before your warranty period ends
If anything in the report isn’t clear, ask us. The Standard Survey includes a follow-up consultation, and the Premium Survey includes an in-person one.
Put the warranty or defects period end date in your diary. Book a check well before it so snags can be raised.
What this survey can’t tell you
Some things cannot be seen without opening up the roof, so a survey has limits:
- How the roof will perform for years to come
- Parts of the roof we can’t see safely
- Nails and clips under the slates or tiles
If in doubt, call 07833 053749 or use the contact form and we’ll point you to the right survey. The full list of what we check.
What this survey covers
- New-build homes
- Loft conversions and dormers
- Flashings and valleys
- Replacement roofs
- Ridges and verges
- New flat roofs
Rented homes, blocks and businesses
Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time, and they’re priced for the size.
Questions from Harlington
Can parking be tricky for a visit in Harlington?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
How do I find out if my home in Harlington is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Do you test for asbestos?
No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, like cement roof sheets or soffits on buildings from before 2000, we flag them.
Is Harlington in your area?
Yes. Our area covers London and South East England, Harlington included.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
Do you lift tiles to check the fixings?
No. We do not open up the new roof, so fixings under the coverings cannot be checked. We note what couldn’t be seen.
Can you survey at the weekend?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Tell us which days suit you when you book.
New roof snagging around Harlington
About 3.6 miles east lies Osterley House, a reminder of how long the area around Harlington has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. If your home in Harlington is one of them, bay roofs, hips and later dormers each have their own details. Material and age explain a lot of what turns up on the day, whether the roof is old or brand new.
If you live in an older home near Church of St Peter and St Paul, ask the seller about past roof repairs, because older roofs often have patched valleys, replaced slates and reset ridges. If you let a flat or house near Heathrow Terminals 2 & 3 Rail station, it is worth knowing a roof’s condition before you buy it, or before you sign off new roofing work on it.
