How a roof leak investigation works in Lashenden
Most roof leaks start at a joint rather than the middle of a slope. Common entry points include chimney and wall flashings, valleys, parapet and box gutters, and the upstands and outlets on flat roofs. Each of these is checked in turn and follow the evidence. Every chimney, dormer and roof light adds more joints to check. Each one is checked from wherever it’s safe to see it. We survey the roof space, valleys and parapet gutters and rooflights and dormers, and the problems we are asked to look at most are damp underlay across a wide area and damp walls below an overflowing gutter.
Roofs in small places like Lashenden often stand in the open, so storms hit ridges, verges and chimneys hard. Damp in old stone, brick or timber walls is slow to dry out, which makes finding the cause quickly worthwhile. A written record also helps if you need to explain it to anyone else.
Findings are set out part by part, from the coverings down to the gutters, with a note and a photo for each point. It records what’s sound as well as what isn’t.

Why it is worth a survey now in Lashenden
Water damage grows the longer it’s left. Wet timbers start to decay, plaster softens and insulation stops working. Tracing it now means less to put right later. Older cottages and farmhouses around Lashenden can have roof timbers that have been there a very long time, and water through a failed covering can rot timber if it’s left.
Every price we give includes VAT, and the written report is part of the package. Roof leak investigation starts from £150, including VAT. Size, height and access decide where your roof falls.

Lashenden questions
Does a conservation area affect roof work in Lashenden?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is Lashenden in the area you cover?
Yes, Lashenden is within the area we cover. We cover the whole of London and South East England. You can call 07833 053749 or send us an email with the address and a few details.
How long does the visit take?
The visit usually takes about one to two hours at a typical home, and longer for a large or complex roof. We’ll give you an idea of timing as you book.
Why is the stain in a different place from the leak?
Water rarely drops straight down. It runs along rafters, battens or underlay before it drips, so the entry point is often well away from the mark. We follow the route back instead of guessing.
Do you look in the loft space?
Usually, if there is one and it can be reached safely. From inside, the underside of the roof often shows damp, staining or daylight that cannot be seen from outside.
Can you survey a shared roof?
Yes, if whoever owns or manages the building agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
Do you use drones?
Yes, where it is applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
Common roof problems in Lashenden
Some water in the loft isn’t rain at all. Moist air from bathrooms and kitchens condenses on the cold underside of the roof, particularly in lofts with blocked eaves. Wet nail tips and damp underlay over a wide area are classic signs.
Common reasons to book include:
- Drips from nail tips in a cold loft
- Water through the ceiling under a flat roof
- Water coming in around a roof light or dormer
- Staining where a gutter or parapet meets the wall
In and around Lashenden, as anywhere, a roof is easiest to deal with when its problems are found early.
Questions to ask before you book
- Is there a chance to talk the report through?
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Their track record with similar roofs
- Which viewpoints they use to see the roof
Roof leak investigations in Lashenden: local notes
Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand, before anyone quotes for re-roofing.
Landlords with a home close to Headcorn station may find that finding the cause of a leak fast keeps a tenant’s home dry and the work focused.
