What affects the price in Harlow
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- How complicated the roof is, with its valleys, chimneys and parapets
- The type of building, from a house to a block or an office
- The use of thermal imaging or a drone
- Which survey package you book
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.

Roof leak investigations for homes and businesses in Harlow
On older houses, leaks frequently start at lead work and hidden gutters. Lead flashings crack or lift, valley linings wear and parapet gutters overflow when outlets block. If your home has a butterfly roof, the central valley gutter is a common culprit in heavy rain. Parapet walls and their gutters are checked from wherever it is safe. The findings are recorded with photos. We survey rooflights and dormers, the roof space and valleys and parapet gutters, and the problems we’re asked to look at most are damp patches next to the stack and condensation that looks like a leak.
Strong winds lift loose tiles, slates and ridge pieces in towns like Harlow as anywhere. Many policies treat gusts of about 55 mph as storm conditions, though it varies. Photos and a written account help you show what happened, whether to an insurer or a roofer. Policies usually exclude wear and tear, which is why the age of the damage matters.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Questions from Harlow
Is my home in Harlow 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 is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
My home in Harlow has a flat-roofed garage or porch. Is it worth having that looked at?
Frequently, yes, so mention it as you book. Many homes in new towns like Harlow have flat-roofed garages and porches, and felt roofs often last around 15–20 years.
Will you fix the leak as part of this?
Our job here is to trace the leak and explain it, not to carry out the repair. With the report, a roofer knows exactly where to look.
How much does a roof leak investigation cost in Harlow?
Prices start from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, inc. VAT.
What should I do before you arrive?
Check the loft can be reached. Gather any photos and notes about when it leaks, and let us know about past repairs. Keep catching drips and keep water away from electrics.
How experienced are you?
Over 20 years and more than 5,000 surveys.
Can a leak be traced on a dry day?
Usually, yes. Moisture detection shows where materials are damp even on a dry day. If a leak only appears in driving rain from one direction, we will tell you what we found and what’s most likely.
When you need someone else
To be straight with you, there are limits to any roof survey:
- Faults hidden behind ceilings or boarding
- Carrying out the fix
- An intermittent leak that shows no trace on the day
If you’re not sure which survey you need, phone 07833 053749 or email us and we will give you a straight answer. What our survey covers.

How the survey changes by roof type
Parapet and box gutters
Linings, joints and outlets are inspected wherever it is safe, and look for signs of past overflowing.
Flat roof upstands and outlets
On a flat roof, a leak can show some distance from the split. Moisture readings and thermal imaging can help narrow it down where conditions suit.
What happens if roof problems are left?
Patching the spot above the stain frequently doesn’t work. The real way in may be a metre or more away. We find the probable source before anyone starts work, so the repair is aimed at the right place. In a family home in Harlow, a small roof fault lets water into places you cannot see, soaking loft insulation, wall tops and timbers. By the time it shows inside, the job has grown.
Our price is from £150, including VAT. The final price depends on how big and how high the roof is, access and which survey you book.

- Insured for professional indemnity and public liability
- We hold a CAA Flyer ID and Operator ID

Should I look at the roof myself first?
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
How it works
After the inspection, everything we found is written up in a report with photographs, emailed to you. As for time on site, most surveys take between one and two hours for most homes, though a hard-to-trace leak can take longer. In Harlow, many roofs join a neighbour’s, so we check what can be seen of the shared parts from your side. Tell us about any known leaks, past repairs or building work when booking, so time on site goes where it is needed.
- 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.
- You get photos, the likely cause and clear recommendations.
Before the survey
- For flats, check roof access has been agreed
- If you’re buying, let the agent know when we are coming
- Point out any leaks or damp patches
Arrange a survey
Not sure which survey you need? It is easiest to call 07833 053749 or use the contact form and describe the roof and why you want it surveyed. We will talk you through the options and what they cost.
Advice
Leaks and storm damage in Harlow
In Essex, older buildings are often clay-tiled, many with weatherboarding, alongside a good many post-war and newer estates. Different coverings let water in at different points, which shapes where the search starts. Harlow is one of the post-war new towns. Many homes in the new towns date from the post-war decades, with concrete interlocking tiles, low-pitched roofs and flat-roofed garages and porches. Low pitches let wind-driven rain reach further under the tiles, and flat-roofed garages and porches are common leak points.
Homes near green spaces like Harlow Marsh can get more leaves in their gutters in autumn, and blocked gutters overflow and soak walls. If you live in an older home near St Andrew's Methodist Church, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks. If you let a flat or house near Harlow Town station, a clear finding on where water gets in helps you brief a roofer straight away.
