Questions from Ashford
Is there anything to prepare before you come to Ashford?
Mostly, it’s about access: the loft hatch, any locked gates and where to park in Ashford. It also helps to know about any leaks or earlier repairs.
Do you cover Ashford?
We do. Every survey there gets the same written report with photographs.
Is it a leak or condensation?
Condensation can look very like a leak. Drips from nail tips, damp underlay over a wide area and poor loft ventilation point towards condensation. We look at the pattern, take moisture readings and tell you which is more likely.
How long does the visit take?
It usually takes an hour or two on an ordinary house, and longer for a large or complex roof. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Is this a RICS survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
Will you go up on the roof?
Only if it’s safe. We inspect whatever is safely visible: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where applicable. The report says if anything couldn’t be seen.
What’s the best way to book?
Just call 07833 053749 or use the contact form with the address. After a few questions, we confirm the price and fix a day, weekday or weekend.
About our roof leak investigation in Ashford
Some leaks only appear in certain weather. Wind-driven rain, an overflowing gutter or snow melt may be what triggers it. 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 detection shows which materials are still damp. Common reasons to book are damp walls below an overflowing gutter and leaks below a flat extension roof, on chimney stacks, slate and tile slopes and the roof space.
Many homes around Ashford have been extended, often with flat roofs or dormers, and where an extension meets the house is a common leak point. The flashings and upstands at those joints get a proper look, inside and out. Water can run along the top of a wall or a joist before it shows, so the stain isn’t always the place to look.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. If something couldn’t be seen safely, the report is clear about it.

What a roof leak investigation looks like in Ashford
Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Horsham stone slab roofs survive on some old buildings in Surrey. The covering and its details give the first clues when tracing where water is coming from. If your home is older, it is worth knowing whether it’s listed or in a conservation area before planning roof work. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas.
Landlords with a home close to Ashford Surrey station may find that a clear finding on where water gets in helps you brief a roofer right away. If you own one of the older houses in the streets near Parish Church of St Matthew, leaks on older roofs frequently start at lead flashings, valleys or around old chimney stacks.
Ashford is about 6 miles south of Hayes, in Surrey. Ashford is one of many places we visit across Surrey, for homes and businesses alike. Ashford is one of the towns and villages in Surrey where we work for roof leak investigations. Guildford is in our area too.
Roof leak investigations in TW15, TW19 and TW13 work the same way as everywhere else we cover. We offer roof leak investigations to properties on Church Road, Station Road and London Road and the roads around them. With the A30 and A308 close by, Ashford is easy for us to reach. We also cover the places around Ashford: Littleton Common (1 mile south-east), Ashford Common (1 mile south-east), West Bedfont (1 mile north), Stanwell (2 miles north) and Hounslow (2 miles east). Further out, we also cover Guildford (14 miles south), Woking (9 miles south-west), Camberley (13 miles south-west), Epsom (11 miles south-east), Ewell (11 miles south-east) and Egham (4 miles west).
Near you in Ashford
We work in homes and buildings around Clarendon Primary School and Thomas Knyvett College. There’s a railway station in Ashford itself: Ashford Surrey station. Other landmarks nearby include Ashford Hospital (0.7 miles north) and Spelthorne Museum (2.2 miles west). Open spaces near Ashford include Staines Reservoirs and Kempton Park Reservoirs.
Why act early in Ashford
Water damage grows the longer it’s left. Damp spreads into rafters, ceilings and insulation. Tracing it now means less to put right later. In a family home in Ashford, a small roof fault lets water into places you can’t see, soaking loft insulation, wall tops and timbers. By the time it shows inside, the job has grown.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before you book.

Common roof problems in Ashford
Flat roofs fail with age and wear. Felt often lasts around 15 to 20 years, and as it ages it splits, blisters and opens at the laps. Upstands and outlets are common weak points.
Typical things we’re asked to look at include:
- Leaks below a flat extension roof
- Condensation that looks like a leak
- Leaks that appear only in driving rain
- Wet patches high on an inside wall
Anyone responsible for a site like Spelthorne College will know that on a building that size, finding the source of a drip means looking well beyond the stain.
Choosing a roof surveyor
- Whether they hold professional indemnity and public liability insurance
- Whether the loft is part of the inspection
- Which viewpoints they use to see the roof
- Is there a chance to talk the report through?

Practical tips
A few practical points come up again and again on our surveys. They apply to most roofs:
- Let us know if there are tanks or pipes in the loft
- Record whether it leaks in every downpour or only some
- Keep water away from lights and sockets
- Mention earlier attempts to fix the leak
Once the work is done, hold on to the report. If water appears again, it shows what was found before.
After a storm, check the roof from the garden and the street. Pieces of slate or tile in the garden mean something has moved. Prompt repairs stop gaps turning into leaks.
Honest limits
No survey can tell you everything, and it’s better to know them up front. Bear these in mind:
- Leaks from plumbing, tanks or pipework rather than the roof
- Carrying out the fix
- An intermittent leak that shows no trace on the day

What we look for on each type of roof
Valleys
A valley leak can appear well away from the valley inside. From inside the roof space, we follow the water’s route back.
Lead flashings
Mortar fillets are sometimes used instead of lead. They crack as the roof and wall move, and water runs down behind them.
The survey, step by step
We check the roof from outside and, where it’s relevant and there is safe access, from inside the loft space too. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey normally takes between one and two hours for most homes, though a hard-to-trace leak can take longer. In Ashford, many roofs join a neighbour’s, so shared parts are looked at as far as they can be seen from your property. Tell us about any known leaks, past repairs or building work as you book, so time on site goes where it is needed.
- We start with what you’ve seen: where the stain is and when it gets worse.
- Inside, we check the damp area and the loft 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.
- We email a report with photographs, the likely entry point and recommendations.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Leave side gates unlocked
- Clear the way to the loft hatch
How to book
