How a roof leak investigation works in Ilmer
Most roof leaks start at a joint rather than the middle of a slope. Common entry points include chimney and wall flashings, valleys, parapet and box gutters, and the upstands and outlets on flat roofs. Each of these is checked in turn and follow the evidence. Chimneys, dormers and roof lights each add joints of their own. Each one is checked from wherever it is safe to see it. We survey chimney stacks, valleys and parapet gutters and lead flashings, and the problems we are asked to look at most are drips from nail tips in a cold loft and water marks that spread in wet weather.
Many homes in small places like Ilmer face open ground, so storms hit ridges, verges and chimneys hard. Damp in old stone, brick or timber walls is slow to dry out, so it pays to find the cause quickly. A record with photos is useful if you need to show the damage to anyone else.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

The survey, step by step
Safety comes first on every visit. We inspect what can be seen safely, and anything we can’t see is noted in the report. The survey typically takes about 1–2 hours, more where the leak is intermittent or the roof is large. For a village or hamlet like Ilmer, the journey is planned ahead of time: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- You pick a Basic, Standard or Premium Survey.
- A visit is booked for a weekday, Saturday or Sunday.
- We inspect inside and out, starting from the stain.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- You get photos, the likely cause and clear recommendations.
Getting ready for the survey
- Jot down any questions you want answered
- Dig out any old roof reports or invoices
- For a flat or shared roof, check access with the building owner or managing agent

Related advice
Before and after the survey
Most of what helps is simple and safe from the ground. Our suggestions:
- Leave roof access to professionals
- Protect furniture and flooring under the leak
- Write down the wind direction and rain when it leaks
- Let us know what has already been tried
Standard includes a follow-up consultation to talk the findings through, while Premium includes one in person. It’s a chance to ask about anything in the report.
After a downpour, look in the roof space with a torch, keeping to boarded areas. Watch for water marks, wet underlay and damp wood. Photograph anything new.
What we are asked to look at in Ilmer
Every flat roof covering has a working life. A felt roof frequently 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.
It is worth booking a survey if you’ve seen:
- Drips from nail tips in a cold loft
- Damp patches next to the stack
- Leaks below a flat extension roof
- Leaks at a dormer or roof window
If you live in an older home near Church of St Peter, water on an older roof tends to find its way in at the lead, the valleys or the chimney.
Before booking any roof surveyor
- What experience they bring
- What follow-up you get after the report
- Which parts of the roof they’ll actually see
- Will they check the loft as well as the outside?
What a roof leak investigation looks like in Ilmer
Thatch survives on some older buildings in Buckinghamshire’s villages. 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. There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so check with the council.
If you look after a building like Longwick Church of England Combined School, tracing a leak on a big roof starts with where the water appears and works back. For landlords with property near Monks Risborough station, a clear finding on where water gets in helps you brief a roofer right away.

What else we do in Ilmer
Ilmer questions
Is Ilmer within the area you cover?
Yes. Ilmer is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and South East England. Just mention lanes, gates or anything else about the route as you book.
Does a conservation area affect roof work in Ilmer?
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.
Will you check the loft?
Yes, where the survey calls for it and there is safe access. Inside, we look for damp, staining, gaps and sagging.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first, with whoever owns or manages the building. Let us know about it as you book and we’ll plan the survey around it.
Can thermal imaging help find my roof leak?
It can, when the conditions are right. The best results come after a sunny day, on a dry roof with little wind. Damp areas can hold heat differently from dry ones. Its findings are confirmed with a moisture check.
Do you climb onto every roof?
Only when it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone.
Is this an asbestos survey?
No. We do not sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
What we look for on each type of roof
Lead flashings
Water from a failed flashing can travel down the wall or along a rafter. That’s why we check the flashings near a stain, not just the one directly above.
Slate and tile slopes
Cracked mortar lets ridge and hip tiles move. Water then gets in along the top of the roof.
