- Holes left by work on the roof
- Leaks through a flat roof with no obvious cause
What we do, step by step
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. All in, the survey usually takes a time that depends on the membrane area and the build-up, which we set out in the quote. Somewhere as small as Dedham, access is often the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Preparing for the visit
- For flats, check roof access has been agreed
- Have any paperwork from past roof work to hand
- Let us know about parking near the property
Book a survey
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. Otherwise, simply phone 07833 053749 or email us whenever suits you.
Advice
Electronic leak detection for homes and businesses in Dedham
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye, so your roofer can repair them. You get a written report with photos of each breach found. If you’re worried about stains far from any visible defect and punctures from foot traffic or tools, we can find out what’s behind it.
Somewhere as small as Dedham, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access ahead of time. Garages and outbuildings are easy to forget, so mention any you want included when booking.
Where we cannot see part of the flat roof membrane, the report says so. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Why get it checked now?
Cutting open a flat roof to find a leak can cause more damage. ELD aims to locate the breach first, so the repair can be targeted. For older village homes like those around Dedham, the right replacement materials aren’t always easy to find quickly. Spotting a problem early leaves room to find them.

What else we do in Dedham
Electronic leak detection around Dedham
Dedham is within about 4 miles of the coast, and places near the sea get more salt in the air and more wind than inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. About 0.5 miles south-east lies Castle House, a reminder of how long the area around Dedham has been built on. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
Take an older house close to Parish Church of St Mary: the flat roofs on later extensions tend to wear out long before the main roof. If you let a flat or house near Manningtree station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Dedham is about 6 miles north-east of Colchester, in Essex. Whether the building in Dedham is a house, a flat or a commercial unit, the roof can be surveyed on a weekday or at the weekend. Across Essex, we cover Dedham. For surveys nearby, see our Chelmsford page.

Useful tips for Dedham property owners
Small things make a difference. Some pointers:
- Record dates and spots where water appears
- Keep foot traffic on flat roofs to a minimum
- Let us know about the membrane and build-up if you know it
- Don’t leave water getting in
If we think the leak isn’t coming through the membrane, the report says so, with a suggestion of what to check next.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
Common roof problems in Dedham
Other trades on the roof can puncture the waterproofing. Engineers fitting equipment, solar panels or aerials may leave damage behind.
Problems we come across often include:
- Patched roofs that still leak
- Punctures from foot traffic or tools
- Water coming in under a flat roof
- Leaks through a covered membrane
If you look after a building like Dedham Church of England Voluntary Controlled Primary School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Questions to ask before you book
- Their report turnaround times
- How much experience they have with roofs like yours
- Will they check the loft as well as the outside?
- Whether you can ask questions once you have the report
What a survey costs
Several things affect the price of a survey:
- Any need for thermal images or a drone flight
- The type of building, from a house to a block or an office
- The size of the roof
- The height of the building and how the roof can safely be seen
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You will know the figure before booking.
Getting in touch
You don’t need to know any roofing terms. Just tell us:
- How the loft is reached, if there is one
- What’s prompted the survey
- When you need the report by
- Where any leaks, stains or damp patches show inside
To arrange a survey, phone 07833 053749 or use the contact form and tell us the address and what’s prompted the survey. We will confirm the price before booking.
Questions from Dedham
Do you cover smaller places like Dedham?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Does being near the coast affect roofs in Dedham?
It can do. Dedham is within about 4 miles of the sea, and coastal roofs tend to see faster wear on metal parts and more wind lifting loose pieces.
How long will testing take?
The roof’s size and build-up decide how long it takes. You’ll know roughly how long before we start.
Will I get photos?
Yes. We photograph the roof as we go, and they go into the written report.
What does electronic leak detection do?
ELD passes a small electrical current across the roof to locate holes in the membrane. The current only gets through where the membrane is breached, which shows us where the hole is.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Let us know what you know about the roof and we’ll check whether ELD will work.
How do you choose the testing method?
The method is chosen to suit the roof. Low-voltage methods are typically carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
Checking the roof from ground level
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That is where a survey comes in.
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.
