About our roof leak investigation in Charlton
Some ‘leaks’ aren’t leaks at all. Condensation in a cold, poorly ventilated loft can drip from nails and timbers, and the stains look much like a leak. Knowing which it is means the right fix can be done, since the cure for one won’t solve the other. The pattern of the damp, the ventilation and the timing all help us decide. If you’re worried about damp ceilings under a flat roof and stains around a skylight, we can find out what’s behind it.
Somewhere as small as Charlton, older roofs have frequently been repaired many times. That makes it hard to tell new damage from old wear, and the difference matters, especially to an insurer. We look at what can safely be seen and set out what we find. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
We write the report in plain English, so you do not need to be a roofer to follow it. Photographs show what each point refers to, with the urgent items made clear.

Roof by roof
Chimney stacks
Chimneys let water in through pointing, flaunching, flashings and open pots. We check each one as far as we can safely see.
Valleys
Stains from a valley leak frequently show some distance off. From inside the loft space, we follow the water’s route back.
What a roof leak investigation looks like in Charlton
If your home is older, it’s worth knowing whether it’s listed or in a conservation area before planning roof work. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Where water gets in depends a good deal on what the roof is made of and how it is detailed.
If you own a rental within reach of Hitchin station, a clear finding on where water gets in helps you brief a roofer straight away. If you look after a building such as Highbury Infant School and Nursery, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
Charlton is about 1 mile south-west of Hitchin, in Hertfordshire. Charlton is one of many places we visit across Hertfordshire, for homes and businesses alike. Our Hertfordshire coverage includes Charlton and the places around it. We also survey roofs in Milton Keynes.
All of SG5 is covered for roof leak investigations, from the main roads to the quietest streets. We also cover the places around Charlton: Gosmore (1 mile south-east), Hitchin (1 mile north-east), Benslow (1 mile north-east), Bearton (1 mile north) and Westmill (1 mile north). Within a short drive, we also cover Hemel Hempstead (15 miles south-west), Stevenage (5 miles south-east), St Albans (13 miles south), Welwyn Garden City (11 miles south), Harpenden (9 miles south) and Hatfield (12 miles south).
Around Charlton
We work in homes and buildings around Hitchin Boys' School, The Three Moorhens Public House and Kingshott School, among other places. The nearest railway station is Hitchin station, roughly 1.4 miles north-east of the centre. Well-known places in the area include North Hertfordshire Museum (0.8 miles north-east) and Lister Hospital (3.3 miles east). Open spaces near Charlton include Markham's Hill and Oughtonhead Nature Reserve.
Leave it or get it looked at?
Leaks tend to get worse, not better. Each storm can open a gap a little more. Tracing it now lets you plan the work rather than react to it. In a small place like Charlton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, inc. VAT. The roof’s size, height and access matter as well.
Why book with us
- Covered by professional indemnity and public liability insurance
- An independent view of the roof
- Over 20 years’ experience

Landlords, agents and block managers in Charlton
An agent can book and manage the survey for a landlord, and the report can go to both. Access is agreed with the tenant in advance.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
When to book a survey in Charlton
Slipped or missing slates and tiles let rain reach the underlay. Old bitumen felt may cope for a while, but it tears and sags with age, while some very old roofs have nothing under the coverings. On slate roofs, slipping is frequently caused by corroded nails.
Most people get in touch after spotting something like this:
- Water that shows only in certain storms
- Stains around a skylight
- Damp underlay across a wide area
- Water dripping from rafters or underlay
Living close to Butts Close is pleasant, but mature trees mean leaves in gutters and valleys each autumn, so outlets and downpipes are worth watching.

What we do, step by step
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit usually takes about one to two hours at a typical home; commercial roofs usually need 3–4 hours. Somewhere like Charlton needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there’s safe access and from the roof where it is safe.
- You let us know where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from each safe vantage point.
- We email a written report showing where the water most likely gets in.
Preparing for the visit
- Keep pets out of the way during the survey
- If you are buying, let the agent know when we’re coming
- Move anything stored under the loft hatch

Charlton questions
Is Charlton within the area you cover?
Yes, we do. Our area covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Charlton in the area you cover?
Yes. We cover the whole of London and South East England, and Charlton is part of that. You can ring 07833 053749 or send us an email with the address and some details.
Can you give me structural calculations?
No. We are experienced roof surveyors, and visible signs like sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
How much does a roof leak investigation cost in Charlton?
Roof leak investigation starts from £150, including VAT. The final figure depends on the roof and the package you choose, confirmed before anything is booked.
How should I prepare for the leak investigation?
Note when the leak appears and what the weather was doing. Move stored items away from the loft hatch. If water is near any fittings, have an electrician check them.
Do you test for asbestos?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Can every leak be traced?
Not every leak can be pinned down in a single visit. Many leave clear signs, but intermittent leaks that need particular weather can be harder. We report what we found and the likeliest sources.
