Roof leak investigations in Gun Hill: local notes
Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Horsham stone slab roofs survive on some old Sussex buildings, alongside 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. With Horselunges Manor about 1.9 miles south-east, Gun Hill sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
Whatever the street in Gun Hill, a roof costs least to look after when faults are caught early.

About our roof leak investigation in Gun Hill
On older houses, leaks often start at lead work and hidden gutters. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. A central valley gutter on a butterfly roof often turns out to be the source in heavy rain. Parapet walls and their gutters are checked from wherever it is safe. Our report shows what we found, with photos. If you’ve noticed damp underlay across a wide area and brown rings on upstairs ceilings, a survey will tell you what’s going on, whatever the roof.
Many homes in small places like Gun Hill face open ground, 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 main slopes down to the gutters and outlets, with a note and a photo for each point. You’ll see the good as well as the bad.

Practical tips
Small things make a difference. Our tips:
- Mention any plumbing above the damp area
- Have an electrician check any wet fittings
- Mention earlier attempts to fix the leak
- Put a bucket under the drip and move valuables
Any roofer you ask to quote can work from the report. The photos show the defects and where they are, rather than at the stain.
Keep the roof space ventilated. Air movement keeps condensation down, and condensation is a common false alarm. Keep insulation clear of the eaves.
What a roof leak investigation does not cover
Before you book, it is worth knowing what a survey will not do:
- Carrying out the fix
- A promise to find every leak on a single visit
- Leaks from plumbing, tanks or pipework rather than the roof

Common questions in Gun Hill
Will you come out to Gun Hill?
Yes. Gun Hill is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and South East England. Just mention lanes, gates or anything else about the route when you book.
Do you carry out roof surveys in Gun Hill?
Yes. We cover the whole of London and South East England, and Gun Hill is part of that. Just ring 07833 053749 or email us and let us know about the property.
What’s the best way to book?
Just phone 07833 053749 or send us an email with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
How fast do I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. All of them come by email, ready to forward.
How long does a roof leak investigation take?
It usually takes about 1–2 hours for most homes, though a hard-to-trace leak can take longer. Report times depend on the package.
Will you walk on the roof?
Not always. Safety comes first, and fragile or steep roofs cannot always be walked on. We use safe viewpoints, the loft space and a drone where applicable, and the report records anything we couldn’t see.
How long have you been surveying roofs?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys across London and the South East.
How the survey changes by roof type
Lead flashings
Lead flashings seal the joints at chimneys, walls and dormers. Lifted, split or slipped lead is a common cause, and for flashings that have been patched with bitumen.
Chimney stacks
We check the outside of the stack and the breast inside, not a flue, gas or sweep inspection.
Landlords, agents and block managers in Gun Hill
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out with the most urgent first where relevant, which helps with budgets and planning.
Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
How the survey works
Before we start, tell us why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. Most visits take about one to two hours, more where the leak is intermittent or the roof is large. Older roofs in small places like Gun Hill can have low, tight loft spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- 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.
Before the survey
- Buyers: confirm access with the estate agent or seller
- Keep pets in another room
- Note where any stains or damp appear

What happens if roof problems are left?
If a leak has been ‘fixed’ before and has come back, the cause was probably missed. We look past the obvious spot and check each likely route. That’s frequently what breaks the cycle. Matching old materials, like handmade tiles or stone slates, can take time to source. That’s one more reason to find defects before they become urgent.
Every price we give includes VAT. Our price is from £150, including VAT. We confirm the exact price before booking.
