Roof leak investigations for homes and businesses in North Crawley
Some ‘leaks’ aren’t leaks at all. In a badly ventilated roof space, condensation can form under the roof and drip, leaving marks that look just like rainwater. Telling the two apart matters, since the cure for one won’t solve the other. The pattern of the damp, the ventilation and the timing all help us decide. If you’ve noticed staining where a gutter or parapet meets the wall and a leak that comes and goes with the weather, a survey will tell you what’s going on.
Roofs in small places like North Crawley 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.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

When to book a survey in North Crawley
Many leaks begin at a flashing. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in.
Common reasons to book include:
- Leaks below a flat extension roof
- Damp walls below an overflowing gutter
- Leaks at a dormer or roof window
- Condensation that looks like a leak
Anyone responsible for a site like North Crawley CofE School will know that a leak through a large roof is frequently found some distance from where the water shows inside.
Questions to ask before booking
- How they plan to inspect the roof safely
- What exactly goes into their report
- How soon the report will arrive
- What experience they bring
When you need someone else

Roof by roof
Lead flashings
Mortar fillets are sometimes used instead of lead. They crack as the roof and wall move, letting rain run behind the joint.
Chimney stacks
Water that gets in at the top can show up lower down. Unused flues with open pots can let rain straight in.
Roof leak investigations around North Crawley
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Different coverings let water in at different points, which shapes where the search starts. The wider area around North Crawley has a long history of building, with Linford Manor about 4.8 miles west. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
The streets around a church such as Church of St Firmin are often among the oldest in a place, and if your house is among the older ones nearby, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.

North Crawley questions
Is North Crawley in the area you cover?
We do. The survey and report are the same in North Crawley as anywhere else, and visits run on weekdays and weekends.
Is North Crawley within the area you cover?
Yes, North Crawley is covered. Our area covers London and the South East, and smaller places are part of that. Longer journeys are simply planned beforehand.
How much is a survey?
Our price is from £150, including VAT. The final figure depends on the roof and the package you choose, confirmed before anything is booked.
How should I prepare for the leak investigation?
Check the loft can be reached. Gather any photos and notes about when it leaks, plus details of past repairs. In the meantime, catch the water and keep it clear of lights and sockets.
Will I get photos?
Yes. Photographs are part of every report, so you can see exactly what each finding refers to.
Why is not the leak directly above the stain?
Water follows the easiest path, not the shortest. On a flat roof it can travel under the covering before it finds a way through the ceiling. Tracing that path is the heart of a leak investigation.
Do you carry out surveys on Saturdays and Sundays?
Surveys run on any day of the week. To find a day that suits you, ring 07833 053749 or send us an email.

The survey, step by step
We don’t take risks to get a closer look. We inspect whatever is safely visible, and if part of the roof cannot be seen, the report says so. The survey usually takes about one to two hours for most houses, or half a day or so for a commercial building. Older rural homes like those around North Crawley can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near 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.
Preparing for the visit
- Jot down any questions you want answered
- Agree roof access with the managing agent if it is shared
- Find any records of previous roof work
Booking a survey

Advice
Tips from our surveys
Here are a few things we’d tell any owner:
- Check the loft is accessible
- Leave roof access to professionals
- Don’t touch fittings that water is reaching
- Let us know what has already been tried
Where we find more than one possible route, we say which is most likely and why. We say which items need prompt attention, so you know what to deal with first.
Have flashings and flat roofs looked at every few years. Flashings, valleys and flat roof details are frequent weak points, and catching wear early keeps water out.
