Harlesden New Roof Snagging
New roof snagging around Harlesden, with a written report you can act on. Weekday and weekend visits available.
- Signs of condensation in the loft space
- Underlay not dressed into the gutter
- Loose or badly finished ridge tiles
Practical tips
There’s plenty you can do without going near the roof. Here’s what helps most:
- Diary the defects period end date
- Arrange the inspection before settling the final bill
- Look for debris left in gutters from ground level
- Put any issues to your roofer in writing
If anything in the report isn’t clear, ask us. With the Standard Survey there’s a follow-up consultation and Premium an in-person consultation.
Don’t settle the final bill until the roof has been inspected if your contract allows it. It gives the roofer a reason to finish everything.
New roof snagging for homes and businesses in Harlesden
The best time for snagging is before the final payment while the roofer can still come back easily. If you’ve already paid, check before any defects or warranty period runs out. That gives you time to raise any snags. You get a written list of snags with photographs, ready to pass on in good time. We’re frequently asked to look into poorly finished verges and debris left in gutters or valleys, across flashings and valleys, new flat roofs and ridges and verges.
Many London homes have been converted into flats, extended at the back or given a loft conversion with a dormer. Every alteration brings new junctions, flashings and flat-roof areas to look at. If you are buying a flat or house in Harlesden, or have just had new roofing work done, those junctions are frequently where problems start. Dormer cheeks, lead work and new flat roofs are worth checking closely, as faults there are easy to miss.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

What else we do in Harlesden
How it works
We will ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes between one and two hours for a house, with bigger or more complicated roofs taking longer. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Harlesden runs like any other.
- 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 be seen safely.
- We check valleys, flashings and gutters, and the underlay at the eaves where it is visible.
- We look in the roof space, where there’s safe access, and around the property for debris or damage.
- The snags are written up with photos for you to share with your roofer.
Preparing for the visit
- Keep pets inside or away from the areas we’re looking at
- Make a note of anything you’d like us to look at
- Note where any stains or damp appear
Booking a survey
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, so phone 07833 053749 or drop us an email with the details.

Questions from Harlesden
Do you carry out roof surveys in Harlesden?
Yes, Harlesden is within the area we cover. We cover the whole of London and South East England. You can call 07833 053749 or send us an email with the address and a few details, and we will talk through which survey suits.
How do I find out if my home in Harlesden is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Can you inspect the roof on a new-build home?
Yes, the inspection works the same as for a re-roof. You get a photo report of any snags for you to pass to your builder.
What does a new roof inspection cost?
The Basic Survey starts from £150, the Standard from £250 and the Premium from £400, all with VAT included. Just ring 07833 053749 or use the contact form for a price.
How long will you be on site?
It usually takes between one and two hours for most houses, while a commercial roof takes nearer three to four hours. You’ll know roughly how long when we arrange it.
Does the weather affect the survey?
It can, depending on the survey. Drones can’t fly safely in high wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions are not right, we’ll talk to you about another date.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
Harlesden homes and their roofs
Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Each material has its own typical faults, which is what a buyer or the owner of a new roof needs to know about. About 3.1 miles south-west lies Pitzhanger Manor, a reminder of how long the area around Harlesden has been built on. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
As a London address, Harlesden can be tricky for parking: a visitor permit or a nearby bay makes the day easier. For an older house near a landmark such as Church of All Souls, ask the seller about past roof repairs, because older roofs often have patched valleys, replaced slates and reset ridges.

Can I check my roof myself?
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That’s where a survey comes in.
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
What we are asked to look at in Harlesden
Most homeowners cannot get a good look at their new roof. From the pavement, many faults are invisible and you may be asked to pay anyway.
Signs worth acting on include:
- Gaps at new flashings
- Cracked mortar at the ridge or hips
- Offcuts and broken tiles left behind
- Gutters or fascias damaged during the job
For landlords with property near Willesden Junction station, it is worth knowing a roof’s condition before you buy it, or before you sign off new roofing work on it.
