About our roof leak investigation in Downside
Our roof leak investigations cover Downside and the wider South East. We visit on weekdays, Saturdays and Sundays. The investigation covers inside and out, from the stain to the likely entry points. The findings come in a written report with photos. If it’s leaking right now, contain the water and keep it clear of electrics, then call 07833 053749 or use the contact form. If you’ve noticed staining where a gutter or parapet meets the wall and water marks that spread in wet weather, a survey will tell you what’s going on.
Roofs in small places like Downside 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 record with photos is useful if you need to show the damage to anyone else.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Leaks and storm damage in Downside
About 2.7 miles north-west lies Byfleet Manor, a reminder of how long the area around Downside has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area. In Surrey, older roofs are frequently handmade clay tile, with tile-hanging on many upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. The covering and its details give the first clues when tracing where water is coming from.
If you look after a building like St Matthew's CofE Aided Infant School, tracing a leak on a big roof starts with where the water appears and works back. For landlords with property near Cobham & Stoke Dabernon station, a clear finding on where water gets in helps you brief a roofer straight away.
Downside is about 4 miles west of Leatherhead, in Surrey. Surveys in Downside work the same way as everywhere we cover: a careful inspection, photos and a written report. Our area takes in places right across Surrey. We also survey roofs in Guildford.

What we look for on each type of roof
Parapet and box gutters
Hidden gutters run behind parapets or between roofs. When their outlets block, water rises over the lining and runs indoors.
Lead flashings
Wherever a roof meets a wall or stack, a flashing keeps rain out. We check for lead that has lifted, split or slipped, and for flashings that have been patched with bitumen.
Signs you need a roof leak investigation in Downside
A chimney stack has plenty of places for rain to get in. Water can enter through crumbling mortar, cracked flaunching, worn flashings or uncapped pots. The damp may appear on a chimney breast, a ceiling or in the loft.
Signs worth acting on include:
- Drips from nail tips in a cold loft
- Water through the ceiling under a flat roof
- Damp patches next to the stack
- Ceiling stains that grow after rain
For an older house near a landmark like St Michael's Chapel, the leak may come from a chimney, a valley or tired lead rather than the covering itself.

What we do, step by step
On the day, we begin with a quick chat about the roof and anything that is worrying you. We then inspect everything that can be seen safely, from the ground, from windows, in the loft space and by drone where it applies. The survey typically takes about 1–2 hours for most homes, though a hard-to-trace leak can take longer. Around Downside, older homes can have small or awkward roof spaces, so tell us about the loft hatch and any ladder. We only go where it’s safe.
- You tell us where the water shows and when it appears.
- Inside, we check the damp area and the roof space above it.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- 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.
Getting ready for the survey
- Find any records of previous roof work
- Keep pets out of the way during the survey
- Point out any leaks or damp patches

Checking the roof from ground level
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That part is for a survey.
Keep a simple record: dates of leaks, photos from the ground and any work done on the roof. Share it with us as you book.
Downside: your questions answered
Do you carry out roof surveys in Downside?
Yes. Our area covers London and South East England, and Downside is part of that. Just call 07833 053749 or email us and let us know about the property, and we’ll talk through which survey suits.
Do you cover smaller places like Downside?
Yes, smaller places are covered as well as towns. We survey roofs across London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
How soon will I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline as you book.
Is it a leak or condensation?
Many apparent leaks turn out to be condensation. A leak usually shows in one area and follows rain, while condensation is often spread out and worse in cold weather. We tell you which it is most likely to be.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Do you carry out surveys on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day. Just say which days work for you.
