Seal Roof Leak Investigation
We take a careful look at the leaking roof at your property in Seal, and put it all in a report with photos.
- Water coming in around a roof light or dormer
- Staining around the chimney inside
- Leaks that appear only in driving rain
Roof leak investigation in Seal: what you get
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 look at the roof surface and the ceiling below to narrow it down. Flat roofs over extensions, garages and dormers are frequent sources of leaks. An ageing felt roof is a frequent culprit. Typical surveys look at leaks that appear only in driving rain and wet patches on loft insulation, on the roof space, flat roof details and chimney stacks.
Being in a small place like Seal makes no difference to how a leak or storm damage is looked at: we simply plan the journey and access ahead. It’s useful to know where the water appears, in what weather, and what you’ve seen outside, along with any repairs done before. If you have photos of the water coming in, they help as well.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Landlords, agents and block managers in Seal
If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, phone 07833 053749 or send us an email with the addresses.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
What you can safely check yourself
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
What you can’t do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where it applies.
Before and after the survey
You don’t need to be a roofer to help. What helps most:
- Take dated photos of the leak
- Write down the wind direction and rain when it leaks
- Check the loft is accessible
- Mention earlier attempts to fix the leak
If the leak turns out to be condensation, the report says so, with recommendations on ventilation. It saves chasing a leak that is not there.
Plan a roof survey every few years. They’re where most leaks start, and wear is easier to deal with before water gets in.
How we price roof leak investigations
To price your survey, we look at:
- The roof’s overall size
- How many separate roofs there are, like extensions, dormers and garages
- How complicated the roof is, with its valleys, chimneys and parapets
- Height and safe access
The Premium Survey includes thermal imaging and drone inspection where applicable, from £400 inc. VAT. We will tell you which package suits the questions you have.
What to tell us when you contact us
Some details help us suggest the right survey and price. When you contact us, tell us:
- Any marks or damp showing indoors
- The reason for the survey, like buying, a leak or storm damage
- Photos of the roof, taken safely from the ground or a window
- Your postcode, so we can check access and travel
If you have photos of the roof, send them over. Pictures from the ground or a window are fine; never climb up to get a better view. To send them or to book, ring 07833 053749 or use the contact form.
The survey, step by step
On the day, we start by asking what you’ve noticed and what you’d like to know. We then inspect everything that can be seen safely, from the ground, from windows, in the roof space and by drone where it applies. The survey usually takes between one and two hours, more where the leak is intermittent or the roof is large. In a hamlet or village like Seal, a postcode does not always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.
- We start with your notes and photos of the leak.
- Inside, we look at 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 viewpoint.
- We email a written report showing where the water most likely gets in.
Getting ready for the survey
- Have any questions written down, so nothing gets missed
- Make sure we can get to the back of the property
- Find any records of previous roof work
Book a survey
When you are ready to go ahead, ring 07833 053749 or send us an email. From there it’s a case of choosing a package, agreeing the price and fixing a day.

What a roof leak investigation looks like in Seal
Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Different coverings let water in at different points, which shapes where the search starts. The wider area around Seal has a long history of building, with Knole House about 1.8 miles south. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
For landlords with property near Bat & Ball station, a clear finding on where water gets in helps you brief a roofer right away. Homes near green spaces like Kemsing Down can get more leaves in their gutters in autumn, and blocked gutters overflow and soak walls. Take an older house close to Church of St Peter and St Paul: old mortar, worn lead and slipped slates are the usual suspects when water gets in.

What else we do in Seal
Leave it or get it looked at?
A leak rarely stays small. Damp spreads into rafters, ceilings and insulation. Finding the source early keeps the damage down. For an older or listed building in a place like Seal, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. We’ll give you the figure before anything is booked.

FAQs for Seal
Is my home in Seal listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you cover Seal?
Yes, Seal is one of the places we work. The survey and report are the same in Seal as anywhere else.
What does a roof survey cost?
Prices start from £150, including VAT. We confirm the price for the job before you book, based on the roof’s size, access and package. For a price, phone 07833 053749 or email us.
Can you give me structural calculations?
No. Our survey is not a structural engineer’s report, and it does not include calculations. If we see signs that need an engineer’s opinion, we will recommend one.
Do you climb onto every roof?
Not unless it’s safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed, and the report notes anything we couldn’t see.
What do I do with the report?
The report comes by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
How long have you been surveying roofs?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.
