Roof leak investigation in Horley
Some leaks only appear in certain weather. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. Notes on when it leaks, and what the weather was doing, help us, along with any photos you’ve taken. Even on a dry day, a leak normally leaves clues: stained timbers, tide marks and damp underlay. Moisture readings show where materials are still wet. If you are worried about brown rings on upstairs ceilings and leaks that appear only in driving rain, we can find out what’s behind it, on valleys and parapet gutters, lead flashings and chimney stacks alike.
In a village or hamlet like Horley, older cottages and farmhouses often have roofs that have been patched over many years. A new leak may be fresh damage or the latest sign of long-term wear, and the difference matters, particularly to an insurer. We look at what can be seen safely and set out what we find. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
The report records the leaking roof as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

Landlord and commercial surveys in Horley
Letting agents can arrange access with tenants, at a time agreed ahead of time. We survey on weekdays, Saturdays and Sundays, which helps when tenants work during the week.
Where a roof is shared: we need access agreed with the building owner or managing agent. Mention it when you get in touch and we’ll plan the visit with that in mind.
Horley roofs and the weather
Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Each of these roof types has its own typical places for water to get in. With Upton House about 3.2 miles west, Horley 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.
If you own a rental within reach of Banbury station, a tenant living with a leak needs the cause found, not just the stain painted over. For an older house near a landmark such as Church of St Ethelreda, the leak may come from a chimney, a valley or tired lead rather than the covering itself.

Useful tips for Horley property owners
A little preparation and a few simple habits help. Some pointers:
- Keep a photo record of the damp patch
- Check whether pipes or tanks run near the stain
- Move stored items away from the hatch
- Have an electrician check any wet fittings
Standard includes a follow-up consultation to talk the findings through, and Premium includes an in-person consultation. You can ask us about anything that is not clear.
After a downpour, look in the loft space with a torch, keeping to boarded areas. Watch for water marks, wet underlay and damp wood. Take photos of anything that changes.
Your questions about roof leak investigations in Horley
Does a conservation area affect roof work in Horley?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Is Horley within the area you cover?
Yes, Horley is covered. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
Can every leak be traced?
We can’t promise it. Water can travel a long way, and some leaks only show in particular storms. Where the source is not certain, we list the likely routes in order.
Are you insured?
We’re covered by professional indemnity and public liability insurance, for every survey we carry out.
Do I have to be there for the survey?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is frequently shared, so the freeholder or managing agent needs to agree access. We inspect only the parts we are allowed to reach.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we don’t carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Honest limits
It helps to know what a survey will not do before booking:
- Leaks that only appear in weather we can’t recreate
- Whether rotten timbers meet design loads
- Plumbing leaks that look like roof leaks
If you are not sure which survey you need, phone 07833 053749 or drop us an email and we will give you a straight answer before booking. The full list of what we check.
What we check
- The roof space
- Chimney stacks
- Valleys and parapet gutters
- Slate and tile slopes
- Flat roof details
- Rooflights and dormers
- Lead flashings
The survey, step by step
Where it’s relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit typically takes between one and two hours, more where the leak is intermittent or the roof is large. Older roofs in small places like Horley can have low, tight loft spaces, so it is useful to know whether there is a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- From the loft space, we trace the water’s route where there’s safe access.
- 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.
How to prepare
- Find any records of previous roof work
- For flats, check roof access has been agreed
- Leave side gates unlocked

Can I check my roof myself?
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.
Signs you need a roof leak investigation in Horley
Flashings are one of the commonest sources of roof leaks. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. Once that seal cracks or lifts, water gets behind it, often well away from where it shows.
Problems we come across often include:
- Leaks that appear only in driving rain
- Wet patches high on an inside wall
- Water coming in around a roof light or dormer
- Staining around the chimney inside
For businesses in and around places such as Castle Quay Shopping Centre, a leak can close part of a shop or office, so finding the cause quickly matters.
What to check before booking
- How soon the report will arrive
- Whether VAT is added on top
- Whether the inside of the roof is included
- What the survey won’t cover
