Roof leak investigations in West Green: local notes
West Green is part of Crawley, one of the post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Leaks on homes like these frequently come from flat-roofed additions or from rain driven up under low-pitched tiles. An older home may be listed, or stand 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.
If you look after a shop, office or commercial unit, for example near County Mall, a quick answer on where water is coming in keeps a business running. Landlords with a home close to Crawley station may find that a clear finding on where water gets in helps you brief a roofer straight away.

Roof leak investigations for homes and businesses in West Green
On a flat roof, water can travel a long way under the covering. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Standing water puts extra pressure on every weak point. We check both the covering and the room underneath. Leaks under flat extension, garage and dormer roofs are common. An ageing felt roof is a frequent culprit. We are frequently asked to look into damp walls below an overflowing gutter and leaks below a flat extension roof, on the roof space, chimney stacks and flat roof details.
Houses in smaller places like West Green can stand more in the open, so wind and driving rain find any weakness in ridges, verges and flashings. A leak that only appears in certain weather frequently points to an exposed detail. Tell us when it happens when you contact us. Gutters and downpipes on the exposed side are worth a look as well.
Where we can’t see part of the leaking roof, the report says so. That way, it is clear what was covered and what wasn’t, and what we’d suggest next.

What we are asked to look at in West Green
Condensation is frequently mistaken for a leak. Warm, moist air from the house rises into a cold roof space and condenses, especially where ventilation is poor. Wet nail tips and damp underlay over a wide area are classic signs.
People typically book a survey after spotting something like this:
- Wet patches on loft insulation
- Water marks that spread in wet weather
- Leaks that appear only in driving rain
- Leaks below a flat extension roof
Living close to Grattons Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and an overflowing gutter soon means a wet wall.
Questions to ask before you book
- Whether they hold professional indemnity and public liability insurance
- Whether you get a written report with photos
- What’s outside the scope of the survey
- Is VAT included in the price?
What happens on the day
Safety comes first on every visit. We inspect everything that’s safely in view, and anything we cannot see is noted in the report. The survey normally takes about 1–2 hours on an ordinary house, with bigger or more complicated roofs taking longer. A visit to a smaller place like West Green is no different on the day: outside, inside and from any safe vantage point, in that order. It’s useful to show us anything you’ve already noticed.
- 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.
- We email a written report showing where the water most likely gets in.
Before we arrive
- Find any records of previous roof work
- Have any questions written down, so nothing gets missed
- Check the loft hatch can be reached
Booking a survey
Our price is from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can call 07833 053749 or send us an email to find out.
Related advice
West Green: your questions answered
Should a flat-roofed garage or porch in West Green be checked too?
Often, yes, so mention it when booking. Many homes in new towns like Crawley have flat-roofed garages and porches, and felt roofs often last around 15–20 years.
Is my home in West Green 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 need to get into the loft?
If the survey needs it and the loft space can be reached safely, yes. Please clear anything stored under the hatch, and if the loft can’t be reached safely, the report says so.
What’s in the survey report?
Written findings with photographs, covering the condition of the leaking roof, the defects we found and what we recommend. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where it applies and structural analysis.
Can you give me structural calculations?
No. We note visible signs like sagging or deflection, but we’re not structural engineers and do not carry out calculations. If we think you need an engineer, the report says so.
How experienced are you?
Over 20 years and more than 5,000 surveys.
How fast do I get the report?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, let us know as you book.
What we can’t see
It helps to know what a survey will not do before you book:
- Whether rotten timbers meet design loads
- The repair itself (the investigation finds and reports the cause)
- Water from pipes, tanks or heating systems
Not sure which survey suits your roof? You can call 07833 053749 or drop us an email and we’ll tell you before booking. What a survey covers and doesn’t.
What this survey covers
- Slate and tile slopes
- Lead flashings
- Rooflights and dormers
- The roof space
- Valleys and parapet gutters
- Chimney stacks
- Flat roof details
Before and after the survey
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Some tips:
- Photograph the stain each time it appears
- Note the weather when the leak shows
- Stay off ladders and the roof
- Clear the loft hatch so we can get in
Standard includes a follow-up consultation to talk the findings through, and Premium includes an in-person consultation. You can ask us about anything that isn’t clear.
Have flashings and flat roofs looked at every few years. Flashings, valleys and flat roof details are frequent weak points, and wear is easier to deal with before water gets in.
Surveys for landlords and agents in West Green
Freeholders and residents’ companies use a roof report to plan and budget.
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
Can I check my roof myself?
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
A DIY look is useful, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
