About our new roof snagging in Northaw Valley
Our report records what we see, with photographs and clear descriptions. If there’s a disagreement about the work, it’s between you and your roofer or builder. Our report gives you an independent record to refer to. The report does not price repairs or settle who is responsible, but it does set out clearly what we found. If you’ve noticed loose or badly finished ridge tiles and underlay not dressed into the gutter, a survey will tell you what’s going on.
Some older homes in villages like Northaw Valley are listed or sit in a conservation area. If so, re-roofing in different materials may need consent, so check with the council before work starts. Whether you’re buying or signing off new roofing, it is worth knowing where you stand, as well as what condition the roof is in. There are about 500,000 listed buildings and around 10,000 conservation areas in England.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Places near Northaw Valley
What else we do in Northaw Valley
Buying a home or a new roof in Northaw Valley
Historic houses such as Wyllyotts Manor, about 2.4 miles west, show how far back building in the area around Northaw Valley goes. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Material and age explain a lot of what turns up on the day, whether the roof is old or brand new.
Landlords with a home close to Crews Hill station may find that it is worth knowing a roof’s condition before you buy it, or before you sign off new roofing work on it. Take an older house close to Parish Church of St Thomas A Becket: ask the seller about past roof repairs, because older roofs frequently have patched valleys, replaced slates and reset ridges.

Tips that help
Some practical points come up on survey after survey. They apply to most roofs:
- Watch for gutters overflowing in rain
- Agree snagging with your roofer at the start
- Send the snagging report to your roofer
- Diary the defects period end date
Your roofer can use the report to put the snags right. Any disagreement about the work is between you and them; we report on what we see.
Put the warranty or defects period end date in your diary. Book a check well before it so snags can be raised.
What we look for on each type of roof
Underlay and ventilation
We look in the roof space, where there is safe access, at the underlay and ventilation.
Valleys
Debris left in a new valley can block it. We note anything left behind.
What you can safely check yourself
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
Common questions in Northaw Valley
Is Northaw Valley within the area you cover?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Do you cover Northaw Valley?
Yes, Northaw Valley is within the area we cover. We survey roofs across London and South East England. You can phone 07833 053749 or drop us an email with the address and some details, and we’ll talk through which survey suits.
What do you check on a new roof?
We check the coverings, ridges, verges, hips, valleys and flashings, along with ventilation, gutters and the underlay at the eaves. We also look for debris left behind and damage to other parts.
Can you survey in bad weather?
Light rain is usually fine; heavy rain and wind are different. In high wind or heavy rain, a drone can’t fly and access may not be safe, so we’d move the date with you.
Is this an asbestos survey?
No. We do not carry out asbestos surveys or testing. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings.
Do you need to get into the loft?
If there’s a loft and safe access to it, yes. The roof space can show things the outside cannot, such as damp timbers, staining or daylight.
How soon after the work should I book a snagging inspection?
Once the roofer says the job is done, ideally before you pay in full. That leaves time to raise anything we find.
How the survey works
The visit has one job: to look at the new roof as closely as is safe and record what we find. Notes and photographs go into the written report. The visit typically takes about one to two hours for a typical new house roof, longer where the roof is large or complicated. Older rural homes like those around Northaw Valley can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen.
- We agree what to focus on, such as a payment date or a warranty period ending.
- The roof is inspected from ground level, vantage points and the roof where safe.
- We work through ridges, verges, valleys and flashings.
- Debris and damage to other parts are recorded.
- We send a written report you can pass on.
Preparing for the visit
- Buyers: confirm access with the estate agent or seller
- Agree roof access with the managing agent if it is shared
- Have any paperwork from past roof work to hand
