Landlord and commercial surveys in Redhill
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Mention it when you get in touch and we’ll plan the survey around it.
We survey roofs for landlords and agents as well as homeowners. A written report with photos gives you a clear record of the leaking roof, useful for planning maintenance.
Roof leak investigations for homes and businesses in Redhill
We investigate roof leaks in Redhill and across London and the South East. We visit on weekdays, Saturdays and Sundays. The investigation covers inside and out, from the stain to the likely entry points. You get a written report with photos and recommendations. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, then call 07833 053749 or email us. We survey rooflights and dormers, flat roof details and lead flashings, and people most often book us about ceiling stains that grow after rain and leaks below a flat extension roof.
Many homes around Redhill have been extended, often with flat roofs or dormers, and where an extension meets the house is a common leak point. Flashings, upstands and the edges of flat roofs are checked alongside the main roof, inside and out. The stain inside is often some way from where water gets in, particularly around extensions.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

What we do, step by step
We’ll ask a few questions first, about the roof’s history, any leaks and past repairs. Then the inspection itself takes an hour or two for most homes, though a hard-to-trace leak can take longer. For a visit in Redhill, we need access to the loft, any rooms with leaks or stains, and the outside of the building. Mention gates, side passages and anything at the back. Weekday and weekend visits are available.
- You get in touch with details of the leak and any photos.
- We check the stain, the ceiling and the loft above it.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- Moisture readings and thermal imaging are used where they help.
- You receive a written report with photos showing the likely source and what needs attention.
Preparing for the visit
- Check pets are kept safely away
- Point out any leaks or damp patches
- Let us know where we can park nearby

Roof leak investigations around Redhill
England has around 10,000 conservation areas and about 500,000 listed buildings. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so the council is the place to ask. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. The covering and its details give the first clues when tracing where water is coming from.
For site and facilities teams at buildings like St Joseph's Catholic Primary School, tracing a leak on a big roof starts with where the water appears and works back. If you run a business near The Belfry, finding where water is getting in quickly keeps disruption down.

Why get it checked now?
Damp in a ceiling or loft can lead to mould. Once mould takes hold, it’s harder to clear. Finding the leak comes first. Extensions and dormers on homes around Redhill frequently hide the first signs of trouble at their joints with the main roof. Left for a few seasons, it can spoil plaster, skirting and flooring inside.
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before you book.

Before and after the survey
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Some tips:
- Let us know about any past repairs to the roof
- Catch drips in a bucket and protect the floor
- Clear the loft hatch so we can get in
- Tell us if there are tanks or pipes in the loft
If there are several possible sources, we list them in order of likelihood. Recommendations are prioritised by urgency where relevant, so you know what to deal with first.
Have flashings and flat roofs looked at every few years. Flashings, valleys and flat roof details are frequent weak points, and catching wear early keeps water out.
When to book a survey in Redhill
Condensation is frequently mistaken for a leak. Warm, moist air from the house rises into a cold roof space and condenses, particularly in lofts with blocked eaves. Drips from nails and damp underlay are typical signs.
It is worth booking a survey if you’ve seen:
- Water marks that spread in wet weather
- Leaks at a dormer or roof window
- Leaks below a flat extension roof
- Water that shows only in certain storms
Take an older house close to Saint Matthew's Church: lead flashings, valleys and old chimneys are typical places for water to get in.
What to check before booking
- Will the report include photos?
- Do they have a CAA Flyer ID and Operator ID for drone work?
- What insurance they carry
- How long they’ve been surveying roofs
What we can’t see
Some things cannot be seen without opening up the roof, and that sets some limits:
- Plumbing leaks that look like roof leaks
- A structural engineer’s report
- Faults hidden behind ceilings or boarding

Your questions about roof leak investigations in Redhill
How should I get ready for a visit in Redhill?
Clear the way to the loft hatch if there is one, and let us know about any leaks, stains or past repairs. Let us know about parking and access in Redhill too.
Do you carry out roof surveys in Redhill?
We do. Every survey there gets the same written report with photographs.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. If one is needed, the report says so.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
Is thermal imaging part of a leak investigation?
Where conditions suit, it can. It works best after a sunny day, with a dry roof surface and little wind. Wet insulation holds heat longer than dry, which can show up on the image. We always check what it shows with moisture readings.
What happens after the survey?
You will receive the report by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Will you go up on the roof?
Only when it’s safe. Safe viewpoints, the loft space and a drone where applicable cover most of what’s needed, and the report notes anything we couldn’t see.
