Anstey Roof Leak Investigation
Tracing where water is getting into your roof in Anstey. We have completed more than 5,000 surveys across London and South East England.
- Damp patches next to the stack
- Water marks that spread in wet weather
- Water coming in around a roof light or dormer
How a roof leak investigation works in Anstey
Older homes have more places for water to get in. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. If your home has a butterfly roof, the central valley gutter is a common culprit in heavy rain. Parapet walls and their gutters are looked at from wherever it is safe. The findings are recorded with photos. Typical surveys look at wet patches on loft insulation and water marks that spread in wet weather, on lead flashings, flat roof details and rooflights and dormers.
Roofs in small places like Anstey often stand in the open, so storms hit ridges, verges and chimneys hard. Once water gets into older walls, it takes a long time to dry, which makes finding the cause quickly worthwhile. A written record also helps if you need to explain it to anyone else.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. That way, it’s clear what was covered and what wasn’t.

Anstey questions
Will you come out to Anstey?
Yes, we do. We survey roofs across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
Do you carry out roof surveys in Anstey?
We do. Every survey there gets the same written report with photos.
Do you survey roofs on blocks of flats?
Yes. A shared roof needs access agreed first. Mention it when you get in touch and we will explain what’s needed.
Will you photograph what you find?
Yes, every report has them. Each finding is shown in a picture where possible.
Can you tell me if my roof has asbestos?
No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.
Will you walk on the roof?
Not always. Safety comes first, and fragile or steep roofs can’t always be walked on. Safe viewpoints, the loft and a drone where it applies let us see the rest.
Can every leak be traced?
We cannot promise it. Some leaks hide well, especially those that need wind-driven rain. Where the source is not certain, we list the likely routes in order.

The survey, step by step
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes between one and two hours for most homes, though a hard-to-trace leak can take longer. If you have questions on the day, just ask. Around Anstey, older homes can have small or awkward roof spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- We inspect inside and out, starting from the stain.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
How to prepare
- If the roof is shared, arrange access with whoever manages the building
- Make a note of anything you’d like us to look at
- Dig out any old roof reports or invoices

Why get it checked now?
Patching the spot above the stain often does not work. Because water travels, the real entry point may be somewhere else. We find the probable source before anyone starts work, so the repair is aimed at the right place. In a small place like Anstey, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. Size, height and access can affect the price too.

Do you need a roof leak investigation in Anstey?
Flashings are one of the commonest sources of roof leaks. Lead or mortar closes the gap wherever a roof meets a wall, chimney or dormer. Once that seal cracks or lifts, water gets behind it.
People typically book a survey after spotting one of these:
- Water dripping from rafters or underlay
- Staining around the chimney inside
- A leak that comes and goes with the weather
- Damp ceilings under a flat roof
For site and facilities teams at buildings such as Anstey First School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.

What affects the cost of roof leak investigations
All our prices include VAT. The things that change the price are:
- How many separate roofs there are, such as extensions, dormers and garages
- How big the roof is
- House, block, shop or office
- Height and safe access
Every price we give includes VAT. Prices start from £150, including VAT. We confirm the price for your survey before booking.
Helping us price your survey
A little information up front helps. Please include:
- Any marks or damp showing indoors
- The reason for the survey, such as buying, a leak or storm damage
- Whether there’s a loft hatch, a shared roof or tricky access
- What kind of property and roof it is
Once you know what you need, ring 07833 053749 or drop us an email. From there it is a case of choosing a package, agreeing the price and fixing a day.
What you can safely check yourself
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please don’t climb up for a closer look.
Different roofs, different checks
Lead flashings
Wherever a roof meets a wall or stack, a flashing keeps rain out. We check for lead that has lifted, split or slipped.
Chimney stacks
Our chimney check is a visual inspection of the stack, not a flue, gas or sweep inspection.
Roof leak investigations in Anstey: local notes
An older home may be listed, or stand in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. Re-roofing in different materials may need permission there. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. The covering and its details give the first clues when tracing where water is coming from.
If you live in an older home near Church of St George, old mortar, worn lead and slipped slates are the usual suspects when water gets in.
