Roof leak investigation in Swanley: what you get
Our roof leak investigations cover Swanley and the wider South East. We visit on any day of the week. We look inside and out, at flashings, valleys, chimneys, gutters and flat roof details. The findings come in a written report with photos. If it is leaking right now, contain the water and keep it clear of electrics, then phone 07833 053749 or email us to arrange a visit. We’re often asked to look into leaks below a flat extension roof and staining around the chimney inside, across chimney stacks, slate and tile slopes and valleys and parapet gutters.
Around Swanley, chimneys on older homes are a common source of leaks, through worn flaunching, failed pointing or lifted flashings. Damp on a chimney breast isn’t always rain from above, which is why it’s worth tracing properly. The stack, its flashings and the loft space beside it are all worth checking.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

How the survey works
Photographs are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. A typical visit takes about one to two hours at a typical home, and about three to four hours for a commercial roof. Being in a smaller place like Swanley does not change how the visit works: we look from the ground, from windows, from the loft and from the roof where it’s safe. Point out any stains, cracks or loose pieces you’ve spotted.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Preparing for the visit
- Leave a clear route to the loft
- Tell us where we can park nearby
- For flats, make sure roof access has been agreed

There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all including VAT. What your roof costs depends on its size, access and what you want to find out.
Booking your survey
Before you get in touch, it helps to have:
- Any marks or damp showing indoors
- The address and postcode of the property
- How the loft is reached, if there is one
- Pictures from the garden or a window, if you have them

Leaks and storm damage in Swanley
Across Kent, older roofs are frequently handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. You’ll also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. The covering and its details give the first clues when tracing where water is coming from. Lullingstone Castle, about 2.9 miles south, is one of the historic houses in the wider area around Swanley. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
Landlords with a home close to Swanley station may find that tracing a leak quickly matters when a tenant is living with it. For site and facilities teams at buildings like St Bartholomew's Catholic Primary School, a leak through a large roof is frequently found some distance from where the water shows inside.

Useful tips for Swanley property owners
Small things make a difference, both for the survey and for the roof itself. Our tips:
- Keep a photo record of the damp patch
- Do not touch fittings that water is reaching
- Note the weather when the leak shows
- Clear the loft hatch so we can get in
Any roofer you ask to quote can work from the report. The photos show the defects and where they are, so the repair is aimed at the cause.
Have leaves and moss cleared from gutters, valleys and outlets, particularly in autumn. Blocked outlets on parapet and flat roofs cause many leaks. Use a professional rather than climbing up yourself.
What we’re asked to look at in Swanley
Flat roofs fail with age and wear. Felt often lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Upstands and outlets are common weak points.
We are often asked to look at:
- Ceiling stains that grow after rain
- Water through the ceiling under a flat roof
- Leaks at a dormer or roof window
- Condensation that looks like a leak
If you live in an older home near St Mary the Virgin, the leak may come from a chimney, a valley or tired lead rather than the covering itself.

Questions from Swanley
Do you cover Swanley?
We do. Every survey there gets the same written report with photos.
Is my home in Swanley listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
How do I arrange a roof leak investigation in Swanley?
To book, phone 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We’ll confirm the price and find a day that suits.
Will I get photos?
Yes, plenty. Each finding is shown in a picture where possible, which makes the report easy to follow.
Do you test for asbestos?
No. We can flag materials that might contain asbestos, but only a specialist asbestos surveyor can confirm it. Buildings built or refurbished before 2000 may contain it.
Does the investigation include the repair?
This service finds and reports the cause, and the repair is separate. With the report, a roofer knows exactly where to look.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so whoever owns or manages the building needs to agree access. We can only inspect what we are given access to.
Roof by roof
Parapet and box gutters
A butterfly roof drains to a central valley gutter. If that gutter or its outlet fails, water can come through the top-floor ceiling.
Chimney stacks
Chimneys let water in through pointing, flaunching, flashings and open pots. We check each one as far as we can safely see, and look for damp on the breast inside.
Can I check my roof myself?
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
During heavy rain, look at the gutters from ground level or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
