How a roof leak investigation works in Theydon Garnon
Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that don’t drain. Standing water puts extra pressure on every weak point. We check the roof surface and the ceiling below. Flat roofs over extensions, garages and dormers are frequent sources of leaks. An ageing felt roof is a frequent culprit. We survey chimney stacks, lead flashings and flat roof details, and common reasons people get in touch are drips in the loft during heavy rain and water that shows only in certain storms.
In a village or hamlet like Theydon Garnon, older cottages and farmhouses often have roofs that have been patched over many years. A new leak may be fresh damage or the latest sign of long-term wear, which matters if you’re thinking of an insurance claim. We check what can be seen safely and set out what we find. Older walls and timbers hold water for a long time, so it is worth finding the cause soon.
After the visit, you get a report with photos, emailed to you. It sets out the condition of the leaking roof, any defects and our written recommendations.

Can I check my roof myself?
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Rented homes, blocks and businesses
Landlords, agents and building managers in Theydon Garnon and across Essex can book any of our surveys. To discuss a property or a block, phone 07833 053749 or use the contact form.
If the property is let, the agent or a tenant can let us in, at a time agreed in advance. We survey on weekdays, Saturdays and Sundays, which helps when tenants work during the week.
Theydon Garnon questions
Is Theydon Garnon in the area you cover?
Yes. Our area covers London and the South East, and Theydon Garnon is part of that. Just phone 07833 053749 or drop us an email and tell us about the property, and we’ll talk through which survey suits.
Is my home in Theydon Garnon 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.
Can you inspect my roof with a drone?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We are a CAA-registered drone operator.
Do you look in the roof space?
Yes, where the survey calls for it and there is safe access. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
Is thermal imaging part of a leak investigation?
We use thermal imaging where it helps, and it’s part of the Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
Do I have to be there for the survey?
Not necessarily. If we only need the outside, we can agree that in advance, but anything inside needs someone there to give access.
How quickly is the report sent?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed.
Why get it checked now?
A leak rarely stays small. Damp spreads into rafters, ceilings and insulation. Finding the source early keeps the damage down. In a small place like Theydon Garnon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all with VAT included. Size, height and access can affect the price too.

Wind, rain and roofs in Theydon Garnon
Clay tiles and timber weatherboarding mark out many of the older buildings in Essex, alongside a good many post-war and newer estates. Knowing the roof type helps narrow down where water may be getting in. About 1.2 miles east lies Hill Hall, a reminder of how long the area around Theydon Garnon has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
For an older house near a landmark such as Church of All Saints, lead flashings, valleys and old chimneys are typical places for water to get in. Take a building like Theydon Bois Primary School: on a building that size, finding the source of a drip means looking well beyond the stain.

How it works
When we arrive, we begin with a quick chat about the roof and anything that’s worrying you. After that, we look at everything we can see safely. The survey normally takes between one and two hours, more where the leak is intermittent or the roof is large. Older rural homes like those around Theydon Garnon can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- From the roof space, we trace the water’s route where there is safe access.
- 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.
Preparing for the visit
- Dig out any old roof reports or invoices
- Leave a clear route to the loft
- Note where any stains or damp appear
Book a survey
Booking is simple: just ring 07833 053749 or use the contact form and give us a few details about the property and we’ll explain which survey suits. The price is agreed up front.
Advice
Before and after the survey
There is plenty you can do without going near the roof. Here’s what helps most:
- Let us know about any past repairs to the roof
- Catch drips in a bucket and protect the floor
- Mention any plumbing above the damp area
- Record whether it leaks in every downpour or only some
Your report arrives by email. It explains the likely entry point, the route the water takes and our recommendations. Turnaround is within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Keep gutters, valleys and outlets clear, especially in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Leave the clearing to someone with the right equipment.
