Cottered Roof Leak Investigation
An experienced roof surveyor for roof leak investigations in Cottered. Over 5,000 surveys and 20+ years behind us.
- Wet patches on loft insulation
- Wet patches high on an inside wall
- Water that shows only in certain storms
How it works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. Somewhere like Cottered needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. The roof is looked at from ground level, from windows, from the loft where there’s safe access and from the roof where it is safe.
- 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.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe vantage point.
- You receive a report with the likely source, photos and recommendations.
How to prepare
- Have any paperwork from past roof work to hand
- Tell us about any leaks, stains or damp patches you know of
- Leave side gates unlocked

Advice
How a roof leak investigation works in Cottered
Our job is to find the likely source and tell you. The report shows, with photos, where we believe the water gets in and how it travels, and recommends what should be done. Whoever does the work then has a clear starting point. The investigation finds and explains the cause, and the repair itself is a separate job. If you’ve noticed brown rings on upstairs ceilings and water coming in around a roof light or dormer, we can find out what’s behind it, on the roof space, lead flashings and slate and tile slopes alike.
Roofs in small places like Cottered often stand in the open, so storms hit ridges, verges and chimneys hard. Damp in old stone, brick or timber walls is slow to dry out, which makes finding the cause quickly worthwhile. A written record also helps if you need to explain it to anyone else.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Why get it checked now?
Damp loft insulation loses much of its value. Insulation can soak up water quietly before anything shows below. Catching it early limits what has to be replaced. Outbuildings and barns around Cottered are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
All our prices include VAT. Prices start from £150, including VAT. We confirm the price for your roof before booking.

Tips from our surveys
From years of surveys, a few habits stand out:
- Photograph the stain each time it appears
- Do not climb onto the roof to look
- Put a bucket under the drip and move valuables
- Tell us if there are tanks or pipes in the loft
Keep the report after the work is done. If water appears again, it shows what was found before, which makes the next step quicker.
Look at the roof from ground level after strong winds. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Prompt repairs stop gaps turning into leaks.
Prices for roof leak investigations in Cottered
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- How big the roof is
- Features like valleys, chimneys, dormers and parapets
- Whether you choose the Basic, Standard or Premium Survey
- How many separate roofs there are, like extensions, dormers and garages
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. We will give you the figure before anything is booked.
What to let us know when you contact us
A little information up front helps. It helps to include:
- When you need the report by
- The property’s address and postcode
- Any marks or damp showing indoors
- How the loft is reached, if there is one
Most bookings start with a short call: phone 07833 053749 or drop us an email, and we will ask about the building and what you need. The price is agreed before a date is set.
Cottered roofs and the weather
Older buildings may be listed or sit 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. Where water gets in depends a good deal on what the roof is made of and how it is detailed.
If yours is one of the older homes in the streets near Parish Church of St John the Baptist, old mortar, worn lead and slipped slates are the usual suspects when water gets in.

A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work around your tenants.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, with the most urgent items set out first.
Do you need a roof leak investigation in Cottered?
A roof valley collects the rain from two slopes. Split linings, slipped valley tiles or debris can push water under the slates or tiles. The stain may appear well away from the valley itself.
It is worth booking a survey if you’ve seen:
- Water dripping from rafters or underlay
- Damp underlay across a wide area
- Damp patches next to the stack
- Leaks at a dormer or roof window
For site and facilities teams at buildings like Freman College, a leak through a large roof is often found some distance from where the water shows inside.
Questions to ask before you book
- What insurance they carry
- Will they check the loft as well as the outside?
- Will the report include photos?
- What follow-up you get after the report

FAQs for Cottered
Is Cottered within the area you cover?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Do you carry out roof surveys in Cottered?
Yes. We cover the whole of London and South East England, and Cottered is part of that. You can ring 07833 053749 or send us an email with the address and a few details.
What do I do with the report?
You will get the report by email, with photos and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
Do you use thermal imaging to find leaks?
We use thermal imaging where it helps, and it is included in our Premium Survey. It picks up temperature patterns rather than water, so we confirm its findings with moisture readings.
Is it a structural engineer’s report?
No. Our survey is not a structural engineer’s report, and it doesn’t include calculations. If we see signs that need an engineer’s opinion, we will recommend one.
Why doesn’t the damp patch line up with the hole?
Water rarely drops straight down. It can follow a timber or the underlay a long way first, so the entry point is often well away from the mark. We follow the route back instead of guessing.
How much is a survey?
Our price is from £150, including VAT. We confirm the price for your roof before you book. To get a price, phone 07833 053749 or send us an email.
