Roof leak investigation in Crawley, Oxfordshire
Know where you stand with the leaking roof before you spend money on it. We carry out roof leak investigations in Crawley.
- Condensation that looks like a leak
- Water through the ceiling under a flat roof
- A leak that comes and goes with the weather
The survey, step by step
Photographs are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available. A typical visit takes about one to two hours for most homes, though a hard-to-trace leak can take longer. Around Crawley, older homes can have small or awkward roof spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- We inspect inside and out, starting from the stain.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Before the survey
- Tell us about parking before the day
- Leave side gates unlocked
- Buyers: confirm access with the estate agent or seller
How to book
We survey roofs seven days a week. To find a date that works for you, ring 07833 053749 or drop us an email with the address and the days you’d prefer.
Advice
Roof leak investigation in Crawley: what you get
Water is good at hiding where it gets in. Water frequently travels along timbers or underlay before it finds a way down, so the stain on your ceiling is seldom right under the hole. We follow it back towards where it starts, one likely route at a time. Patching the spot above the stain often misses the real cause. Finding the route first lets the repair go where it’s needed. If you are worried about staining around the chimney inside and condensation that looks like a leak, a survey will tell you what’s going on, on lead flashings, the roof space and rooflights and dormers alike.
Roofs in small places like Crawley 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 record with photographs is useful if you need to show the damage to anyone else.
What you get is a clear record of the leaking roof on the day we saw it. That makes it useful now and a handy reference later.

Roof by roof
Flat roof upstands and outlets
Outlets drain a flat roof. A blocked outlet leaves water standing, which tests every joint. We check outlets and the covering around them.
Chimney stacks
A stack has several possible ways in for rain. Each is looked at from every safe viewpoint, and look for damp on the breast inside.
Surveys for landlords and agents in Crawley
We survey roofs for letting agents and landlords as well as householders. A photo-illustrated written report gives you a clear record of the leaking roof, which helps you plan work between tenancies.
Letting agents often book on a landlord’s behalf, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
FAQs for Crawley
Do you cover Crawley?
Yes. We survey roofs across London and the South East, and Crawley is part of that. You can phone 07833 053749 or drop us an email with the address and some details, and we’ll talk through which survey suits.
How do I find out if my home in Crawley is listed?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Do you use thermal imaging to find leaks?
It can, when the conditions are right. The best results come after a sunny day, on a dry roof with little wind. Damp areas can hold heat differently from dry ones. We always check what it shows with moisture readings.
Do you look in the roof space?
If there is a loft and safe access to it, yes. The roof space can show things the outside cannot, such as damp timbers, staining or daylight.
Will you go up on the roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the roof space and a drone where it applies.
How long does the visit take?
It normally takes about 1–2 hours for a house, and more on a big or complicated roof. Report times depend on the package.
Do I need to be at home?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
Roof leak investigations around Crawley
West Oxfordshire’s older buildings frequently carry Cotswold stone slates, and a few villages in the county keep their thatch. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Different coverings let water in at different points, which shapes where the search starts. The wider area around Crawley has a long history of building, with Minster Lovell Hall about 1.1 miles west. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
Take an older house close to Church of St John the Evangelist: leaks on older roofs often start at lead flashings, valleys or around old chimney stacks. Anyone responsible for a site like Hailey Church of England Primary School will know that water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
Crawley is about 1 mile north-west of Witney, in Oxfordshire. Crawley gets the same service as everywhere else we work: a careful inspection, photos and a written report. Crawley is one of the towns and villages in Oxfordshire we cover for roof leak investigations. For surveys nearby, see our Oxford page.

What we’re asked to look at in Crawley
Every flat roof covering has a working life. Felt frequently lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Upstands and outlets are common weak points.
Problems we come across often include:
- Wet patches on loft insulation
- Damp ceilings under a flat roof
- Drips from nail tips in a cold loft
- Brown rings on upstairs ceilings
If you own a rental within reach of Finstock station, a tenant living with a leak needs the cause found, not just the stain painted over.
Questions to ask before booking
- How long they’ve been surveying roofs
- Whether any drone flown is registered with the CAA
- Is there a chance to talk the report through?
- Will the report include photos?
Should I look at the roof myself first?
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we look at the roof.
How we price roof leak investigations
What a survey costs depends on the time and equipment it needs. The main factors are:
- Extensions, dormers and garages with roofs of their own
- If the survey needs thermal imaging or a drone
- Chimneys, valleys, parapets and other details
- Basic, Standard or Premium
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. The roof’s size, height and access matter as well.
Helping us price your survey
To price your survey accurately, we’ll ask about:
- Any stains, drips or damp patches you’ve seen indoors
- Your postcode, so we can check access and travel
- When you need the report by
- Any photos you have, taken from ground level or a window
If you have photos of the roof, send them over. Pictures from ground level or a window are fine; never climb up to get a better view. To send them or to book, call 07833 053749 or use the contact form.
