Roof Leak Investigation in Aldenham
Roof leak investigations for homes and businesses in Aldenham. We have completed more than 5,000 surveys across London and South East England.
- Damp walls below an overflowing gutter
- Drips in the loft during heavy rain
- Stains around a skylight
Checking the roof from the ground
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can point to a blockage or a sagging run.
Roof leak investigation in Aldenham
A leak that comes and goes can be the hardest to pin down. 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. We look for the clues it leaves behind, such as tide marks, stained timbers and damp underlay. Moisture readings show where materials are still wet. If you’ve noticed water coming in around a roof light or dormer and water that shows only in certain storms, we can find out what’s behind it, whatever the roof.
Being in a small place like Aldenham makes no difference to how a leak or storm damage is looked at: the journey and access are just planned ahead of time. It is useful to know where the water appears, in what weather, and what you’ve seen outside, plus any earlier repairs. If you have photos of the water coming in, they help as well.
Nothing in the report is left vague: where something needs attention, it says so plainly, along with how urgent it is.

Before and after the survey
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Keep a photo record of the damp patch
- Protect furniture and flooring under the leak
- Note the weather when the leak shows
- Do not touch fittings that water is reaching
If there are several possible sources, we list them in order of likelihood. Recommendations are prioritised by urgency where relevant.
After a downpour, look in the roof space with a torch, keeping to boarded areas. Look for drips, damp patches and stains on timbers. Photograph anything new.
Leave it or get it looked at?
A leak near lights or wiring needs attention quickly. If water is reaching a light fitting or switch, keep clear of it. Then the source needs tracing. In a small place like Aldenham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Our price is from £150, including VAT. The final price depends on how big and how high the roof is, access and the package you choose.

How it works
Safety comes first on every visit. We inspect what can safely be seen, and if part of the roof can’t be seen, the report says so. Most visits take roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. Older rural homes like those around Aldenham can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen.
- You get in touch with details of the leak and any photos.
- Inside, we check the damp area and the roof space above it.
- Outside, we look at every likely route in.
- Moisture readings and thermal imaging are used where they help.
- We email a report with photographs, the likely entry point and recommendations.
Getting ready for the survey
- Point out any leaks or damp patches
- Let us know about parking near the property
- Keep pets out of the way during the survey
Getting a price
If you have photos of the roof, send them over. Take them safely from ground level or a window; never climb up to get a better view. To get started, call 07833 053749 or email us.

Aldenham roofs and the weather
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. With High Elms Manor about 2.5 miles north-west, Aldenham sits in an area with a long building history. 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 any change of roofing material on a listed home needs checking with the council first.
Landlords with a home close to Garston station may find that tracing a leak quickly matters when a tenant is living with it. Shop and office owners around Harlequin Centre may find that a quick answer on where water is coming in keeps a business running. For site and facilities teams at buildings such as Fair Field Junior School, tracing a leak on a big roof starts with where the water appears and works back.

Booking your survey

What a roof leak investigation doesn’t cover
No survey can tell you everything, and we’d rather be clear about that before you book. Keep these in mind:
- Structural calculations (that’s a structural engineer’s job)
- Leaks that only appear in weather we cannot recreate
- Defects hidden under coverings or inside walls without opening up
