Canons Park New Roof Snagging
An experienced roof surveyor for new roof snagging in Canons Park. Over 5,000 surveys and 20+ years behind us.
- Underlay ending short at the eaves
- Gutters or fascias damaged during the job
- Broken coverings left on a new roof
What you can safely check yourself
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. Leave anything above ground level to a survey.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
New roof snagging in Canons Park: what you get
Ventilation matters on a new roof. Where vents have been fitted at the ridge or eaves, we check them, and check the loft space for signs of condensation. We note what we can see. Without enough airflow, a roof space can suffer from condensation, which is easier to put right while the roofer is still involved. It all goes in the report. We survey replacement roofs, new-build homes and flashings and valleys, and common reasons people get in touch are untidy or loose verge details and loose flashings at walls or chimneys.
In London, plenty of houses have been split into flats, extended or fitted with a dormer loft conversion. Every alteration brings new junctions, flashings and flat-roof areas to look at. For a purchase in Canons Park, or for new roofing work there, those junctions deserve a proper look. Lead work around dormers and new flat roofs is easy to get wrong and easy to miss.
It is not only a list of defects. It explains what we found, why it matters and what we recommend.

Before and after the survey
These tips come from what we see on roofs every week:
- Put any issues to your roofer in writing
- Tell your roofer the work will be inspected
- Look for marks or cracks left by the work
- Note the end of any warranty or defects period
Questions about the findings are welcome. With the Standard Survey there’s 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.
How the survey changes by roof type
Clay and concrete tiles
Verge and eaves tiles are where snags often show on tiled roofs. We check them closely.
Underlay and ventilation
At the eaves, the underlay should run into the gutter so water drains away. We check it where it’s visible.

Your questions about new roof snagging in Canons Park
Can parking be tricky for a visit in Canons Park?
Sometimes, yes. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
Is my home in Canons Park listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
How much time does a snagging visit need?
It typically takes roughly 1–2 hours for most houses, with bigger or more complicated roofs taking longer. You’ll know roughly how long when we arrange it.
Are you insured?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
Will you fly a drone over my roof?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Do you survey roofs on blocks of flats?
Yes, if the building owner or managing agent agrees access. On a shared roof we can only inspect the parts we are allowed to reach, and the report makes that clear.
Is this a RICS survey?
No. This is a survey of the roof only, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
How it works
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from every safe vantage point, take photos as we go and record our findings for the written report. Most visits take about one to two hours for a typical new house roof, longer where the roof is large or complicated. In a London area like Canons Park, 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’s safe.
- We ask what work was done and when it was finished.
- The new coverings, ridge, hips and verges are inspected where it’s safe to see them.
- Flashings, valleys, gutters and visible underlay at the eaves are looked at.
- We look in the loft space, where there’s safe access, and around the property for debris or damage.
- You get a photo report listing the snags we found.
Preparing for the visit
- Gather any invoices or paperwork from past roof work
- Agree roof access with the managing agent if it’s shared
- If you are buying, check with the agent that we can get in

What new roof snagging does not cover
Without opening up the roof, some things stay hidden, so a survey has limits:
- Settling a dispute with your roofer or builder
- Details hidden from sight
- Nails and clips under the slates or tiles
If you’re not sure which survey you need, ring 07833 053749 or drop us an email and we will give you a straight answer before you book. What our survey covers.
What we look at
- Loft conversions and dormers
- New flat roofs
- Flashings and valleys
- New-build homes
- Ridges and verges
- Replacement roofs
Why get it checked now?
Small faults on a new roof can grow. Loose details can let water through during the first winter. Spotting them early gives the roofer a chance to put them right. London’s older roofs often have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left unchecked, water soaks into timber and plaster and the damage spreads.
A Basic Survey starts from £150, inc. VAT. The Standard Survey starts from £250 and the Premium Survey from £400, both inc. VAT. You will know the price for your survey before booking.
Why us?
- Clear package prices, with VAT included
- Thermal imaging and drones used where they help
- Over 20 years’ experience
- Drone flown under a CAA Flyer ID and Operator ID

Buying a home or a new roof in Canons Park
Historic houses such as Headstone Manor, about 3 miles west, show how far back building in the area around Canons Park goes. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. If your home in Canons Park is one of them, bay roofs, hips and later dormers each have their own details. Each material has its own typical faults, which is what a buyer or the owner of a new roof needs to know about.
Canons Park is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier. If you let a flat or house near Mill Hill Broadway station, a written report helps before buying a rental or paying for a new roof on one. If you live in an older home near Church of St Lawrence, ask the seller about past roof repairs, because older roofs frequently have patched valleys, replaced slates and reset ridges.
