Do you need a roof leak investigation in 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.
A survey makes sense if you’ve noticed:
- Wet patches high on an inside wall
- Damp on a chimney breast
- Drips from nail tips in a cold loft
- Water through the ceiling under a flat roof
Shop and office owners around County Mall may find that water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Choosing a roof surveyor
- Is there a chance to talk the report through?
- What the survey will not cover
- When you will get the report
- Whether any drone flown is registered with the CAA
About our roof leak investigation in Crawley
Some leaks only appear in certain weather. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. Telling us when it happens helps a lot, along with any photos you’ve taken. We look for the clues it leaves behind, such as tide marks, stained timbers and damp underlay. Moisture readings show where materials are still wet. Common reasons to book are damp walls below an overflowing gutter and drips from nail tips in a cold loft, on rooflights and dormers, valleys and parapet gutters and the roof space.
A place the size of Crawley has every kind of roof, so leaks have many possible sources: failed flashings, blocked valleys, slipped slates, worn mortar, overflowing gutters or a split felt roof. Water often shows up some way from where it got in, which is why the inside and outside are looked at together. Moisture readings, taken alongside a proper look outside, help track where the water has been.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, each with a short note and a photo. It records what’s sound as well as what isn’t.

Booking your survey
The more you let us know, the easier it is to price the survey. When you contact us, let us know:
- What’s prompted the survey
- Where any leaks, stains or damp patches show inside
- Any photos you have, taken from ground level or a window
- How the loft is reached, if there is one
When you’re ready to go ahead, ring 07833 053749 or email us. From there it is a case of choosing a package, agreeing the price and fixing a day, weekday or weekend.
What we do, step by step
Once we’ve finished looking, we write up our findings as a photo-illustrated written report, emailed to you. As for time on site, it normally takes about one to two hours on an ordinary house, and longer for a large or complex roof. For a commercial building or block in Crawley, roof access is agreed with whoever manages it before the visit. At home, it helps to clear a route to the loft and point out any stains or leaks. The written report follows, with photographs.
- 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 is useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
Before the survey
- Tell us about parking before the day
- Make a note of anything you’d like us to look at
- Make sure we can get to the back of the property
Getting a price

What a roof leak investigation looks like in Crawley
Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. Re-roofing in different materials may need permission there. Many older homes in Sussex have handmade clay tiles and tile-hung walls. A few old Sussex buildings still carry heavy Horsham stone slabs. Knowing the roof type helps narrow down where water may be getting in.
If you let a flat or house near Crawley station, a clear finding on where water gets in helps you brief a roofer straight away. The streets around a church such as Friary Church of St Francis and St Anthony are often among the oldest in a place, and if your house is among the older ones nearby, lead flashings, valleys and old chimneys are typical places for water to get in.

What else we do in Crawley
Should I look at the roof myself first?
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
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.
Tips from our surveys
These tips come from what we see on roofs every week:
- Let us know what has already been tried
- Keep a photo record of the damp patch
- Tell us if there are tanks or pipes in the loft
- Do not touch fittings that water is reaching
Standard includes a follow-up consultation to talk the findings through, and Premium includes an in-person consultation. It is a chance to ask about anything in the report.
Have leaves and moss cleared from gutters, valleys and outlets, particularly in autumn. Many leaks start with a blocked outlet. Use a professional rather than climbing up yourself.
FAQs for Crawley
My home in Crawley has a flat-roofed garage or porch. Is it worth having that looked at?
Typically, yes: let us know about it when booking so the visit can include it. Flat-roofed garages and porches are common in new towns like Crawley, and older felt coverings may be near the end of their life.
Is Crawley in the area you cover?
Yes. We work right across London and the South East, and Crawley is part of that. Just phone 07833 053749 or email us and tell us about the property.
Is it the same as a RICS Level 2 or Level 3 survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Do you survey on Saturdays and Sundays?
Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
How long does the visit take?
It usually takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. Report times depend on the package.
How fast do I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
What’s the best way to book?
Simply phone 07833 053749 or use the contact form with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
