Roof leak investigation in Nup End Green
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. Each of these is checked in turn and we follow where the evidence leads. Every chimney, dormer and roof light adds more joints to check. We look at all of them, from each safe vantage point. We survey the roof space, chimney stacks and valleys and parapet gutters, and people most frequently book us about water coming in around a roof light or dormer and condensation that looks like a leak.
In a village or hamlet like Nup End Green, older cottages and farmhouses frequently have roofs that have been patched over many years. That makes it hard to tell new damage from old wear, which matters if you’re thinking of an insurance claim. We check what can safely be seen and set out what we find. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
The written findings come by email, ready to forward to whoever needs them. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

Your questions about roof leak investigations in Nup End Green
How do I find out if my home in Nup End Green is listed?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Is Nup End Green within the area you cover?
Yes. Nup End Green is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when you book.
Will you fix the leak as part of this?
This service finds and reports the cause, not to carry out the repair. With the report, a roofer knows exactly where to look.
Do I need to be at home?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you when booking.
Do you look in the loft space?
Yes, where the survey calls for it and there’s safe access. Inside, we look for damp, staining, gaps and sagging.
What do I do with the report?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
What’s the best way to book?
To book, ring 07833 053749 or use the contact form with the address, the type of property and what’s prompted the survey. We’ll confirm the price and find a day that suits.

Why get it checked now?
A leak rarely stays small. Damp spreads into rafters, ceilings and insulation. Tracing it now means less to put right later. In a small place like Nup End Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Thermal imaging and drone inspection (where applicable) come with the Premium Survey, from £400 inc. VAT. We can help you choose the package that fits what you’d like to know.
What you get with us
- Over 20 years’ experience

How we price roof leak investigations
Several things affect the price of a survey:
- Roof area
- The height of the building and how the roof can be seen safely
- The number of roofs, including extensions and garages
- Which survey package you book
A Basic Survey starts from £150, inc. VAT. The Standard Survey starts from £250 and the Premium Survey from £400, both inc. VAT. We confirm the price for the job before booking.
Booking your survey
A little information up front helps. It helps to include:
- Access details, such as a loft hatch or a shared roof
- What made you get in touch
- What kind of property and roof it is
- Any marks or damp showing indoors
We confirm the price for your survey before you book, so you know the cost up front. Prices start from £150, including VAT. For a price for your roof, call 07833 053749 or use the contact form.
Different roofs, different checks
Valleys
A valley leak can appear well away from the valley inside. From inside the loft space, we follow the water’s route back.
Slate and tile slopes
Slipped, cracked or missing slates and tiles let rain onto the underlay. Ageing felt eventually lets water through.
The survey, step by step
There is not much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll take it from there. A typical survey takes about one to two hours for most homes, though a hard-to-trace leak can take longer. Around Nup End Green, older homes can have small or awkward roof spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- You let us know where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
How to prepare
- Unlock side gates and any roof access doors
- Let us know where we can park nearby
- Gather any invoices or paperwork from past roof work
Arrange a survey
Booking is simple: just call 07833 053749 or send us an email, tell us about the property and we’ll recommend the right survey. The price is agreed up front.

What a roof leak investigation looks like in Nup End Green
The wider area around Nup End Green has a long history of building, with Knebworth House about 0.6 miles north-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Where water gets in depends a good deal on what the roof is made of and how it is detailed.
If you own a rental within reach of Knebworth station, a tenant living with a leak needs the cause found, not just the stain painted over. Take an older house close to Church of St Mary and St Thomas: old mortar, worn lead and slipped slates are the usual suspects when water gets in.
Nup End Green is about 3 miles south-west of Stevenage, in Hertfordshire.

Common roof problems in Nup End Green
Condensation is frequently mistaken for a leak. Moist air from bathrooms and kitchens condenses on the cold underside of the roof, particularly in lofts with blocked eaves. Drips from nails and damp underlay are typical signs.
Common reasons to book include:
- Water that shows only in certain storms
- Damp ceilings under a flat roof
- Ceiling stains that grow after rain
- Condensation that looks like a leak
Homes near green spaces such as Knebworth Park can get more leaves in their gutters in autumn, and blocked gutters overflow and soak walls.
Choosing a roof surveyor
- Which viewpoints they use to see the roof
- How soon the report will arrive
- Is there a chance to talk the report through?
- Whether the loft is part of the inspection
What we cannot see
We only report everything that’s safely in view on the day, so some things are outside what a survey can do:
- Leaks from plumbing, tanks or pipework rather than the roof
- Carrying out the fix
- Structural calculations (that is a structural engineer’s job)
