Osterley New Roof Snagging

- Underlay not dressed into the gutter
- Gutters blocked by building debris
- Gutters or fascias damaged during the job
New roof snagging in Osterley: what you get
Our inspection covers the slates or tiles, ridges, verges, hips and valleys, along with the flashings and ventilation. We check the underlay at the eaves where it is visible as well as the gutters. The report sets out what we found with photographs. We also note debris left behind and any damage to other parts of the building. We survey loft conversions and dormers, ridges and verges and new-build homes, and the problems we’re asked to look at most are gutters or fascias damaged during the job and poorly finished verges.
In a London terrace or conversion, the roof often joins the neighbours’ roofs and shares their stacks and gutters, with parapet walls and party-wall upstands marking where one roof ends and the next begins. That matters for anyone buying in Osterley or checking a new roof there: we inspect what we are given access to and can see safely, which may not include a neighbour’s side. For a flat, the lease normally says who looks after the roof.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

The survey, step by step
On the day, we begin with a quick chat about the roof and anything that’s worrying you. After that, we check everything we can see safely, using the ground, windows, the loft and a drone where it applies. Most surveys take between one and two hours for most homes, depending on how much new work there is to check. In a London area like Osterley, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it is safe.
- You let us know what work was done and when.
- The new coverings and roof edges are inspected as far as can safely be seen.
- Valleys, flashings, gutters and visible underlay at the eaves are checked.
- We check the loft where safe and look for debris or damage.
- You get a photo report of each snag.
Before we arrive
- If the roof is shared, arrange access with whoever manages the building
- Have keys ready for side gates, garages or roof access doors
- Have any questions written down, so nothing gets missed

Advice
Common questions in Osterley
Can parking be tricky for a visit in Osterley?
It can be, so it helps to let us know about permits, visitor bays or off-street space as you book. The visit is then planned around what’s available.
Do you carry out roof surveys in Osterley?
We do. The survey and report are the same in Osterley as anywhere else.
How much is new roof snagging?
The Basic Survey starts from £150, the Standard from £250 and the Premium from £400, all including VAT. Just call 07833 053749 or drop us an email for a price.
Can you survey in bad weather?
Light rain does not typically stop a survey. Heavy rain or strong wind can ground a drone and make the roof unsafe, so if conditions are not right we will arrange another day with you.
What do you check on a new roof?
We check the coverings, ridges, verges, hips, valleys and flashings plus gutters, ventilation and visible underlay at the eaves. We also look for debris left behind and damage to other parts.
What’s the best time to have a new roof checked?
Before the final payment is best, while the roofer is still on hand. If that’s passed, book before any defects or warranty period ends.
Do you use drones?
Yes, where it applies and safe. We are a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. Drone inspection is part of the Drone Roof Survey and the Premium Survey, where applicable.
Why get it checked now?
It’s easier to get snags sorted while money is still owed. Once the job is paid and the roofer has moved on it can be harder to get them back. A snagging report gives you something specific to raise. Many older London roofs have only old felt under the slates, or no underlay at all, so a slipped slate can soon mean water inside. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
Prices quoted always include VAT, and the report is not charged as an extra. Our price is from £150, including VAT. Where your roof sits in the range depends on its size, height and access.

Landlords, agents and block managers in Osterley

Letting agents frequently book on a landlord’s behalf, and the report can go to both. Access is agreed with the tenant in advance.
When to book a survey in Osterley
A roof is hard for most owners to see properly. From the pavement, many faults are invisible before you pay.
Look out for signs like these:
- Cracked mortar at the ridge or hips
- Flashings not properly dressed or fixed
- Debris left in gutters or valleys
- Underlay not dressed into the gutter
Osterley is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
Before you book anyone
- Whether you can ask questions once you have the report
- Their drone registration, if they fly one
- Whether VAT is added on top
- What they will not be able to tell you
What we look for on each type of roof
Valleys
A valley takes water from two slopes, so it needs to be finished well. The lining and the cut coverings along it are looked at.
Flashings
Flashings around chimney stacks are a common weak point, so we check them closely.
When you need someone else
Before you book, it’s worth knowing what a survey will not do:
- How the roof will perform for years to come
- Deciding who is at fault in a disagreement
- Pricing the remedial work

New roof snagging around Osterley
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 Osterley 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. Historic houses such as Osterley House, about 0.3 miles north, show how far back building in the area around Osterley goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
For landlords with property near Isleworth station, the roof is worth checking before you add another property to a portfolio or pay a roofer in full. For an older house near a landmark such as St Mary's Church, the roof may have had decades of patch repairs, and the survey shows where they are.
