New Roof Snagging in Harrow
Find out the condition of the new roof at your property in Harrow. We visit on weekdays and at weekends.
- Tiles or slates sitting out of line
- Poorly finished verges
- Flashings not properly dressed or fixed
Different roofs, different checks
Ridges, hips and verges
Verge details can be rushed, so we check them carefully.
Flashings
Flashings seal the roof to walls and chimneys. We look at how they’re dressed, fixed and pointed.
New roof snagging for homes and businesses in Harrow
We check the coverings, ridges, verges, hips and valleys plus flashings and roof ventilation. At the eaves we look at how the underlay is dressed into the gutter, where it can be seen as well as the gutters. You get a photo report of what we found. We also note debris left behind and any damage to other parts of the building. Typical surveys look at loose or badly finished ridge tiles and broken coverings left on a new roof, on new-build homes, loft conversions and dormers and ridges and verges.
London terraces and converted houses often share a roof line, chimney stacks and gutters with the house next door, with parapet walls and party-wall upstands marking where one roof ends and the next begins. For a purchase or a new roof in Harrow, that shapes what can be checked: only the parts we are given access to and can see safely are inspected. For a flat, the lease typically says who looks after the roof.
The report doesn’t just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

Do you need new roof snagging in Harrow?
Flashings are a common source of snags. If they’re poorly dressed or fixed, water can get in at the first heavy rain.
We’re often asked to look at:
- Offcuts and broken tiles left behind
- Vents that weren’t fitted or are covered
- Underlay ending short at the eaves
- Flashings not properly dressed or fixed
If you let a flat or house near Harrow-on-the-Hill station, a written report helps before buying a rental or paying for a new roof on one.
Choosing a roof surveyor
- When you’ll get the report
- What’s outside the scope of the survey
- Are they insured for the work?
- Whether the loft is part of the inspection
Local roofs and buyers in Harrow
Headstone Manor, about 1.4 miles north, is one of the historic houses in the wider area around Harrow. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Harrow is one of them, bay roofs, hips and later dormers each have their own details. For a purchase or a newly finished roof, the materials decide which details matter most.
For a London address like Harrow, it helps to know about controlled parking before the day. If your home is one of the older ones in the streets near Church of St Peter, the roof’s history matters as much as its looks, and a survey brings the past repairs to light.
Harrow is about 7 miles south of Watford, in Greater London. We visit Harrow as part of our work across Greater London. Harrow is one of the towns and villages in Greater London we cover. We also survey roofs in London.
We survey roofs across HA2, HA1, UB5 and HA3 for new roof snagging. If you need new roof snagging at a property on High Street, London Road and Perceval Square or anywhere close by, we can survey it. With the B457 and B458 close by, Harrow is simple for us to get to. We also cover the places around Harrow: Roxeth (1 mile south), South Harrow (1 mile south), North Harrow (1 mile north-west), Harrow on the Hill (1 mile south-east) and Rayners Lane (1 mile west). Within a short drive, we also cover London (12 miles south-east), City of Westminster (9 miles south-east), Marylebone (10 miles south-east), Kensington (8 miles south-east), St Pancras (11 miles east) and Shoreditch (12 miles east).
Local landmarks in Harrow
Typical jobs here are in homes near Kingsfield Arms, Grange Primary School and Northwick Park and the streets around them. For rail, the closest station is Harrow-on-the-Hill station, roughly 0.7 miles north-east. A little further out are St. George's Shopping Centre (0.7 miles north-east) and Clementine Churchill Hospital (1 mile south-east). Not far away are Islip Manor Meadows and Northala Fields.
Can I check my roof myself?
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book and it will help the survey.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we check the roof.
Before and after the survey
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Check that gutters weren’t left full of offcuts
- Note the end of any warranty or defects period
- Watch for drips in the roof space with care
- Agree snagging with your roofer at the start
You receive a written report with photos of each snag and recommendations, prioritised by urgency where relevant. Pass it on to your roofer or builder.
Keep the final payment until the roof has been checked if your contract allows it. It gives the roofer a reason to finish everything.
Common questions in Harrow
Is my home in Harrow listed or in a conservation area?
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.
Will parking be an issue for a roof survey in Harrow?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
Do you climb onto every roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the roof space and a drone where it applies.
How much is new roof snagging?
New roof snagging starts from £150, including VAT. The price depends on the size of the roof and the access. For a price, phone 07833 053749 or send us an email.
When should I book new roof snagging?
Before the final payment is best so snags can be raised while the job is still open. If that is passed, book before any defects or warranty period ends.
Will you check the loft?
If there is a loft and safe access to it, yes. The loft space can show things the outside can’t, such as damp timbers, staining or daylight.
What’s the best way to book?
Simply phone 07833 053749 or drop us an email with the address. We will ask a few questions, confirm the price and agree a date.
What happens on the day
You don’t need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will take it from there. The survey itself takes about 1–2 hours for a typical new house roof, longer where the roof is large or complicated. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that is the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- First, we note any deadlines and concerns.
- The roof is inspected from the ground, 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.
Before we arrive
- For a flat or shared roof, check access with whoever owns or manages the building
- Move anything stored under the loft hatch
- Dig out any old roof reports or invoices
How to book
