Roof leak investigations for homes and businesses in Lenham
Water is good at hiding where it gets in. Water often travels along timbers or underlay before it finds a way down, so a ceiling stain is rarely directly below the cause. We follow it back towards where it starts. A repair aimed only at the stain can miss the cause entirely. Finding the route first lets the repair go where it is needed. Typical surveys look at wet patches on loft insulation and condensation that looks like a leak, on valleys and parapet gutters, the roof space and flat roof details.
Chimney stacks on older houses around places like Lenham can let water in, at the flashings, the pointing or the mortar round the pots. Damp on a chimney breast is not always rain from above, which is why it is worth tracing properly. It’s worth looking at the stack from outside and at the timbers beside it in the loft.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can plan your next steps.

Lenham questions
Do you cover smaller places like Lenham?
Yes, smaller places are covered as well as towns. We survey roofs across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How do I find out if my home in Lenham is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Does the investigation include the repair?
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.
What’s the best way to book?
To book, ring 07833 053749 or drop us an email with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
Why does not the damp patch line up with the hole?
Because water travels. It can follow a timber or the underlay a long way first, so the entry point is often well away from the mark. We follow the route back instead of guessing.
Do you use thermal imaging to find leaks?
We use thermal imaging where it helps, and it is included in our Premium Survey. It picks up temperature patterns rather than water, so we confirm its findings with moisture readings.
Is it a leak or condensation?
Many apparent leaks turn out to be condensation. Leaks tend to follow wet weather and show in one place, while condensation is often spread out and worse in cold weather. The report explains which it looks like and what to do.
What we’re asked to look at in Lenham
Some water in the loft isn’t rain at all. Warm, moist air from the house rises into a cold roof space and condenses, particularly where ventilation is poor. Drips from nails and damp underlay are typical signs.
Typical things we are asked to look at include:
- Stains around a skylight
- Drips in the loft during heavy rain
- A leak that comes and goes with the weather
- Ceiling stains that grow after rain
If your home is one of the older ones in the streets near St Mary's Church, old mortar, worn lead and slipped slates are the usual suspects when water gets in.
Before booking anyone
- Whether the roof space is looked at, where there is one
- What the survey will not cover
- What follow-up you get after the report
- What insurance they carry
Different roofs, different checks
Valleys
A valley leak can appear well away from the valley inside. From inside the loft space, we follow the water’s route back.
Parapet and box gutters
Hidden gutters run behind parapets or between roofs. When their outlets block, water rises over the lining and runs indoors.
Roof leak investigations around Lenham
About 3.6 miles west lies Leeds Castle, a reminder of how long the area around Lenham has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area. Older houses across Kent frequently have handmade clay or peg tiles, and many have tile-hung walls. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Different coverings let water in at different points, which shapes where the search starts.
Homes near green spaces such as Kiln Wood can get more leaves in their gutters in autumn, and blocked gutters overflow and soak walls. If you let a flat or house near Lenham station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused.
Lenham is about 7 miles south of Sittingbourne, in Kent. We survey roofs in Lenham and the rest of Kent, as part of our work across London and South East England. Our area takes in places right across Kent, from the larger towns to small villages. There’s also a page for Maidstone.
We survey roofs across ME17 for roof leak investigations. Streets in the area include High Street, Mitchell Close and Hatch Road, and we cover them all. Neighbouring places we cover for roof leak investigations include Leadingcross Green (1 mile south), Woodside Green (1 mile north-east), West Street (1 mile north-east), Lenham Forstal (2 miles south-east) and Lenham Heath (2 miles south-east). Within a short drive, we also cover Maidstone (8 miles west), Ashford (9 miles south-east), Sittingbourne (7 miles north), Faversham (9 miles north-east), Minster (13 miles north) and Kings Hill (13 miles west).
What’s near Lenham
Around Lenham, our work takes us to homes and buildings near Kiln Wood, The Red Lion pub and The Lenham School, among other places. There’s a railway station in Lenham itself: Lenham station. Well-known places in the area include Coldbridge Castle (2.7 miles south) and The Dog Collar Museum (3.6 miles west).
What we do, step by step
Photographs are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. A typical visit takes between one and two hours, more where the leak is intermittent or the roof is large. In a smaller place like Lenham, parking is seldom the issue; lanes, gates and long drives are worth mentioning. Low roofs on bungalows can often be seen well from the ground, and the loft shows the rest.
- You let us know where the water shows and when it appears.
- We look at the stain, the ceiling and the loft above it.
- Outside, we check every likely route in.
- Where it helps, we take moisture readings and use thermal imaging.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Getting ready for the survey
- Let us know about parking near the property
- Keep pets out of the way during the survey
- Have keys ready for side gates, garages or roof access doors
Arrange a survey
Roof leak investigation starts from £150, including VAT. What you pay depends on the roof’s size, access and the package, so phone 07833 053749 or email us with the details.
Advice
Tips that help
There’s plenty you can do without going near the roof. Here’s what helps most:
- Put a bucket under the drip and move valuables
- Let us know what has already been tried
- Record whether it leaks in every downpour or only some
- Stay off ladders and the roof
The report gives whoever carries out the work a clear starting point. They’ll see exactly where the problem is, rather than at the stain.
Keep the loft space ventilated. Air movement keeps condensation down, which is often mistaken for a leak. Keep insulation clear of the eaves.

What else we do in Lenham
Why it is worth a survey now in Lenham
Wet insulation does not insulate well. A slow leak can soak it for months before a stain appears. Catching it early limits what has to be replaced. Around Lenham, a leak in an older house can soak into timbers and plaster, and that’s a much bigger job than the original defect.
Prices start from £150, inc. VAT, for a Basic Survey. Standard is from £250 and Premium from £400, both with VAT included. We confirm the price for your survey before you book.
