Roof leak investigations for homes and businesses in Gilston
On a flat roof, water can travel a long way under the covering. Common causes are splits and blisters, tired upstands and outlets that don’t drain. Ponding water makes any weakness worse. We check the roof surface and the ceiling below to narrow it down. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt often lasts around 15 to 20 years, so age is part of the picture. Common reasons to book are damp patches next to the stack and damp ceilings under a flat roof, on chimney stacks, rooflights and dormers and lead flashings.
Many homes in small places like Gilston face open ground, where storms hit ridges, verges and chimneys hardest. 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.
The report records the leaking roof as we found it on the day. That makes it useful now and a handy reference later, like when you want to compare after future work.

Tips from our surveys
There is plenty you can do without going near the roof. What helps most:
- Protect furniture and flooring under the leak
- Check whether pipes or tanks run near the stain
- Stay off ladders and the roof
- Clear the loft hatch so we can get in
Where we find more than one possible route, we say which is most likely and why. Recommendations are prioritised by urgency where relevant, so you know what to deal with first.
After a downpour, look in the roof space with a torch, keeping to boarded areas. Look for drips, damp patches and stains on timbers. Photograph anything new.
How the survey works
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. Most visits take about one to two hours for most homes, though a hard-to-trace leak can take longer. Cottages and farmhouses around Gilston frequently have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- You let us know where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe vantage point.
- You receive a report with the likely source, photos and recommendations.
How to prepare
- Show us where any leaks or stains appear
- Have any paperwork from past roof work to hand
- For a flat or shared roof, check access with whoever owns or manages the building
Getting a price
Every survey is priced before it is booked, so you know the cost up front. Roof leak investigation starts from £150, including VAT. For a price for your roof, ring 07833 053749 or email us.

Roof leak investigations around Gilston
Older buildings in Essex frequently have clay tiles and weatherboarding, alongside lots of post-war and newer estates. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. With Much Hadham Palace about 4.8 miles north, Gilston sits in an area with a long building history. 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.
Living close to Harlow Marsh is pleasant, but mature trees mean leaves in gutters and valleys each autumn. For site and facilities teams at buildings like St Alban's Catholic Academy, on a building that size, finding the source of a drip means looking well beyond the stain. The streets around a church such as Parish Church of St Mary are often among the oldest in a place, and if your house is among the older ones nearby, water on an older roof tends to find its way in at the lead, the valleys or the chimney.

Should I look at the roof myself first?
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.

Gilston questions
Should a flat-roofed garage or porch in Gilston be checked too?
It is often worth it, as these roofs are easy to forget. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check before they’re disturbed.
How do I find out if my home in Gilston is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning, with whoever owns or manages the building. Tell us about it when you book and we will explain what’s needed.
Does the investigation include the repair?
A leak investigation finds and reports the likely source. The repair is not part of it. The report shows where the water gets in and what should be done, which whoever carries out the work can follow.
What’s the best way to book?
Simply call 07833 053749 or drop us an email with the address. After a few questions, we confirm the price and fix a day.
Can you survey at the weekend?
Surveys run on any day of the week. To find a day that suits you, call 07833 053749 or use the contact form.
Does the report include photos?
Yes. We photograph the roof as we go, and the report uses them to show each finding.
When you need someone else
Before you book, it is worth knowing what a survey won’t do:
- Whether rotten timbers meet design loads
- What’s under the covering or behind the plaster
- An intermittent leak that shows no trace on the day

Why act early in Gilston
Damp loft insulation loses much of its value. A slow leak can soak it for months before a stain appears. The sooner the cause is found, the less needs replacing. Older cottages and farmhouses around Gilston can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it is left.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Roof leak investigation starts from £150, including VAT.

What we look for on each type of roof
Valleys
A valley takes the rain from both sides of the roof. Worn or split linings and slipped valley tiles let it under the coverings.
Slate and tile slopes
Slipped, cracked or missing slates and tiles let rain onto the underlay. Ageing felt eventually lets water through.
