How a roof leak investigation works in Northfleet Green
On a flat roof, water can travel a long way under the covering. 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 both the covering and the room underneath. Leaks under flat extension, garage and dormer roofs are common. An ageing felt roof is a frequent culprit. We survey lead flashings, valleys and parapet gutters and flat roof details, and people most frequently book us about damp walls below an overflowing gutter and stains around a skylight.
Roofs in small places like Northfleet Green frequently stand in the open, so storms hit ridges, verges and chimneys hard. Once water gets into older walls, it takes a long time to dry, so it pays to find the cause quickly. A written record also helps if you need to explain it to anyone else.
After the visit, you get a report with photographs, sent by email. It sets out the condition of the leaking roof, any defects and our written recommendations.

Prices for roof leak investigations in Northfleet Green
Not every roof costs the same to survey, for these reasons:

- Whether thermal imaging or a drone is needed
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, all inc. VAT. What your roof costs depends on its size, access and what you want to find out.

Useful tips for Northfleet Green property owners
These tips come from what we see on roofs every week:
- Keep a photo record of the damp patch
- Mention any plumbing above the damp area
- Don’t climb onto the roof to look
- Let us know what has already been tried
Standard includes a follow-up consultation to talk the findings through, and Premium includes an in-person consultation. It’s a chance to ask about anything in the report.
Keep the loft space ventilated. Air movement keeps condensation down, which is frequently mistaken for a leak. Keep insulation clear of the eaves.
Signs you need a roof leak investigation in Northfleet Green
When a slate slips or a tile cracks, the underlay takes the water. Old bitumen felt may cope for a while, but it tears and sags with age, and very old roofs may have no underlay at all. On slate roofs, slipping is frequently caused by corroded nails.
Look out for signs like these:
- Staining around the chimney inside
- Drips in the loft during heavy rain
- Stains around a skylight
- Staining where a gutter or parapet meets the wall
Historic houses such as Cobham College, about 3.2 miles south-east, show how far back building around Northfleet Green goes. Leaks in period homes nearby frequently come from lead work and valleys that have been patched before.

Questions from Northfleet Green
Is the coastal weather around Northfleet Green hard on roofs?
Yes, coastal weather is harder on roofs: there’s more wind, and more salt in the air. Exposed details like ridges, verges, flashings and metal fixings are the ones to watch.
Is Northfleet Green within the area you cover?
Yes. Northfleet Green is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and South East England. Let us know about access, parking and anything unusual about getting there when booking.
Are you insured?
We’re covered by professional indemnity and public liability insurance, for every survey we carry out.
Which days do you carry out surveys?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Let us know which days suit you when booking.
How long have you been surveying roofs?
We have been surveying roofs for over 20 years and have completed over 5,000 surveys.
What should I do before you arrive?
Clear the loft hatch so we can get into the roof space. Have any photos of the leak ready, and tell us about past repairs. In the meantime, catch the water and keep it clear of lights and sockets.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. We look at the parts we are given access to, and the report makes that clear.
Roof leak investigations in Northfleet Green: local notes
Northfleet Green lies within about 4 miles of the sea, so there’s more wind and more salt in the air than further inland. Wind lifts loose slates, tiles and ridge pieces, and driving rain finds any gap they leave, and salt air slowly wears metal fixings. Many older homes in Kent have handmade clay tiles, including Kent peg tiles held by pegs through two holes, and tile-hanging on their upper walls. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Knowing the roof type helps narrow down where water may be getting in.
Homes near green spaces like Castle Hill Park can get more leaves in their gutters in autumn, so outlets and downpipes are worth watching. If yours is one of the older homes in the streets near Church of St Nicholas, old mortar, worn lead and slipped slates are the usual suspects when water gets in.
