About our roof leak investigation in Crowell
Older homes have more places for water to get in. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. A central valley gutter on a butterfly roof frequently turns out to be the source in heavy rain. We check parapets, valleys and flashings from every safe vantage point. Our report shows what we found, with photos. We survey slate and tile slopes, lead flashings and flat roof details, and common reasons people get in touch are wet patches on loft insulation and a leak that comes and goes with the weather.
Many homes in small places like Crowell face open ground, where storms hit ridges, verges and chimneys hardest. Once water gets into older walls, it takes a long time to dry, so it pays to find the cause quickly. A written record also helps if you need to explain it to anyone else.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

Crowell: your questions answered
Is my home in Crowell listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you cover smaller places like Crowell?
Yes, Crowell is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Are you insured?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
What’s in the survey report?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
How much is a survey?
Roof leak investigation starts from £150, including VAT. You will know the price for the job before booking, based on the roof’s size, access and package. For a price, call 07833 053749 or email us.
Do you climb onto every roof?
Only when it’s safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed, and the report notes anything we couldn’t see.
What happens on the day
Before we start, let us know why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit usually takes between one and two hours at a typical home; commercial roofs usually need 3–4 hours. Older roofs in small places like Crowell can have low, tight loft spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- You get in touch with details of the leak and any photos.
- Inside, we check the damp area and the loft space above it.
- Outside, we check every likely route in.
- Moisture readings and thermal imaging are used where they help.
- We email a report with photos, the likely entry point and recommendations.
How to prepare
- Dig out any old roof reports or invoices
- Have keys ready for side gates, garages or roof access doors
- For flats, make sure roof access has been agreed
How to book
A quick phone call is normally the easiest start: phone 07833 053749 or use the contact form, and we will ask about the building and what you need. The price is agreed before a date is set.
Advice
What a roof leak investigation looks like in Crowell
Cotswold stone slates are found on older buildings in west Oxfordshire, and thatch survives in some of the county’s villages. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Each of these roof types has its own typical places for water to get in. About 2.9 miles west lies Adwell House, a reminder of how long the area around Crowell has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
If you let a flat or house near Princes Risborough station, tracing a leak quickly matters when a tenant is living with it. For an older house near a landmark such as Church of the Nativity of the Blessed Virgin Mary, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.

Different roofs, different checks
Parapet and box gutters
Parapet and box gutters sit behind walls or inside the roof. When their outlets block, water rises over the lining and runs indoors.
Slate and tile slopes
Cracked mortar lets ridge and hip tiles move. Water then gets in along the top of the roof.

Signs you need a roof leak investigation in Crowell
A roof valley collects the rain from two slopes. Worn lead, cracked linings or a build-up of leaves and moss can push water under the slates or tiles. The stain may appear well away from the valley itself.
Problems we come across frequently include:
- Water marks that spread in wet weather
- Water coming in around a roof light or dormer
- Water through the ceiling under a flat roof
- Damp walls below an overflowing gutter
For site and facilities teams at buildings such as Mill Lane Community Primary School, on a building that size, finding the source of a drip means looking well beyond the stain.
Questions to ask before booking
- Is VAT included in the price?
- What the survey will not cover
- Will they check the loft as well as the outside?
- Is there a chance to talk the report through?
