How a roof leak investigation works in Hog Hatch
On a flat roof, water can travel a long way under the covering. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Standing water puts extra pressure on every weak point. We look at the roof surface and the ceiling below. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt frequently lasts around 15 to 20 years, so age is part of the picture. Typical surveys look at damp walls below an overflowing gutter and water coming in around a roof light or dormer, across the roof space, chimney stacks and rooflights and dormers.
Around Hog Hatch, chimneys on older homes are a common source of leaks, through worn flaunching, failed pointing or lifted flashings. Damp in a chimney breast can have more than one cause, so it isn’t always obvious where it starts. The stack, its flashings and the loft space beside it are all worth checking.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t.

Hog Hatch questions
How do I find out if my home in Hog Hatch is listed?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Is Hog Hatch in the area you cover?
Yes. We survey roofs across London and the South East, and Hog Hatch is part of that. You can ring 07833 053749 or send us an email with the address and a few details.
Will you go up on the roof?
Only where it is safe to do so. We look at everything that can be seen safely: from ground level, from windows, from inside the roof space, from the roof where it’s safe and by drone where applicable. The report says if anything couldn’t be seen.
Does the report include photographs?
Yes. We photograph the roof as we go, and they go into the written report.
Is this an asbestos survey?
No. Asbestos surveys and testing aren’t part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
How long does a roof leak investigation take?
On site, it typically takes between one and two hours for most houses, while a commercial roof takes nearer three to four hours. Report times depend on the package.
Does someone need to be in?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed when booking.
Rented homes, blocks and businesses
We survey roofs for landlords and agents as well as homeowners. The report gives you a dated record of the leaking roof, with photos.
Any of our surveys can be booked by landlords, agents and building managers in Hog Hatch. To discuss a property or a block, call 07833 053749 or use the contact form.
Roof leak investigations in Hog Hatch: local notes
Farnham Castle, about 0.9 miles south, is one of the historic houses in the wider area around Hog Hatch. If your house is among the older ones, expect a mix of original materials and later repairs on the roof. Handmade clay tiles and tile-hung walls are typical of Surrey’s older houses. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Different coverings let water in at different points, which shapes where the search starts.
Living close to Weybourne LNR is pleasant, but mature trees mean leaves in gutters and valleys each autumn, so outlets and downpipes are worth watching. Shop and office owners around Hart Shopping Centre may find that a leak can close part of a shop or office, so finding the cause quickly matters.
Hog Hatch is about 2 miles north of Farnham, in Surrey. Hog Hatch is one of many places we visit across Surrey, for houses, flats and commercial buildings. Our Surrey coverage includes Hog Hatch and the places around it. There is also a page for Guildford.

Why act early in Hog Hatch
Guesswork repairs are a common reason leaks keep coming back. The real way in may be a metre or more away. An investigation finds the likely cause first. Around Hog Hatch, a leak in an older house can soak into timbers and plaster, and that is a much bigger job than the original defect.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. The roof’s size, height and access matter as well.

Roof by roof
Lead flashings
Some roofs have mortar where you’d expect lead. Fillets crack and pull away over time, letting rain run behind the joint.
Slate and tile slopes
Ridge and hip tiles can loosen as their mortar cracks. Water then gets in along the top of the roof.
What you can safely check yourself
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.

Do you need a roof leak investigation in Hog Hatch?
Many leaks begin at a flashing. Lead or mortar closes the gap wherever a roof meets a wall, chimney or dormer. Once that seal cracks or lifts, water gets behind it.
Signs worth acting on include:
- Damp walls below an overflowing gutter
- Leaks that appear only in driving rain
- Wet patches on loft insulation
- Staining around the chimney inside
Landlords with a home close to Farnham station may find that a tenant living with a leak needs the cause found, not just the stain painted over.
Before booking anyone
- Whether the loft is part of the inspection
- What happens after the report arrives
- How soon the report will arrive
- Do they have a CAA Flyer ID and Operator ID for drone work?
How the survey works
The visit has one job: to see as much of the leaking roof as can safely be seen and record it clearly. Notes and photos go into the written report. It normally takes roughly 1–2 hours on an ordinary house, and longer for a large or complex roof. With a bit of garden around a house, as there often is around Hog Hatch, the roof can be viewed from several angles. Let us know if any side is fenced off or hard to reach. The loft, where there’s safe access, completes the picture.
- You let us know where the water shows and when it appears.
- We look at the stain, the ceiling and the loft above it.
- We check the likely entry points outside, like flashings, valleys, chimneys and gutters.
- We use moisture detection, and thermal imaging where it is useful.
- Your report sets out where the water is most likely getting in, with photos and recommendations.
Before we arrive
- Check we can get to the back of the property
- Mention any parking restrictions on your street
- Agree roof access with the managing agent if it is shared
