Roof Leak Investigation in Deacon's Hill
A careful look at the leaking roof at your property in Deacon's Hill, with photos and a written report.
- Leaks at a dormer or roof window
- Drips in the loft during heavy rain
- Damp patches next to the stack
How the survey works
Expect us to ask a few questions before we start, like when any problem began and what work has been done before. Then the inspection itself takes between one and two hours, more where the leak is intermittent or the roof is large. Older rural homes like those around Deacon's Hill can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can be seen safely.
- 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 looked at, 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
- Have any questions written down, so nothing gets missed
- Have any paperwork from past roof work to hand
- Buyers: confirm access with the estate agent or seller

Roof leak investigations for homes and businesses in Deacon's Hill
Older homes have more places for water to get in. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. If your home has a butterfly roof, the central valley gutter is a common culprit. Parapet walls and their gutters are looked at from wherever it’s safe. The findings are recorded with photos. If you are worried about damp on a chimney breast and leaks at a dormer or roof window, we can find out what’s behind it, on lead flashings, slate and tile slopes and valleys and parapet gutters alike.
Many homes in small places like Deacon's Hill 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 written record also helps if you need to explain it to anyone else.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Leaks and storm damage in Deacon's Hill
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Different coverings let water in at different points, which shapes where the search starts. Historic houses like Headstone Manor, about 4.7 miles south-west, show how far back building in the area around Deacon's Hill goes. 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 a listed home or one in a conservation area may need consent for changes of material.
For landlords with property near Elstree & Borehamwood station, a tenant living with a leak needs the cause found, not just the stain painted over. If yours is one of the older homes in the streets near Church of St Nicholas, old mortar, worn lead and slipped slates are the usual suspects when water gets in. For site and facilities teams at buildings such as Summerswood Primary School, a leak through a large roof is often found some distance from where the water shows inside.

Deacon's Hill: your questions answered
Is my home in Deacon's Hill listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Is Deacon's Hill within the area you cover?
Yes. Deacon's Hill is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and the South East. Let us know about access, parking and anything unusual about getting there when booking.
Will you go up on the roof?
Only when it is safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed, and anything out of sight is recorded in the report.
Why is the stain in a different place from the leak?
Water rarely drops straight down. It can follow a timber or the underlay a long way first, so the entry point is frequently well away from the mark. That is why we trace the route rather than patching above the stain.
Do you test for asbestos?
No. We do not sample or test for asbestos. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.
Can thermal imaging help find my roof leak?
It can, when the conditions are right. It works best after a sunny day, with a dry roof surface and little wind. Wet insulation holds heat longer than dry, which can show up on the image. We always check what it shows with moisture readings.
What happens after the survey?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.

Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
DIY checks: what’s safe
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Share it with us when you book and it will help the survey.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we look at the roof.
Before and after the survey
Most of what helps is simple and safe from ground level. A few suggestions:
- Tell us if there are tanks or pipes in the loft
- Let us know about any past repairs to the roof
- Put a bucket under the drip and move valuables
- Photograph the stain each time it appears
Where we find more than one possible route, we say which is most likely and why. We say which items need prompt attention.
After a storm, check the roof from the garden and the street. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Prompt repairs stop gaps turning into leaks.
What happens if roof problems are left?
A leak that returns after a repair normally means the real source wasn’t found. We look past the obvious spot and check each likely route. It gives the next repair a far better chance. For an older or listed building in a place like Deacon's Hill, repairs may need matching materials and consent, so leaving a defect until it’s urgent leaves less time to plan.
All our prices include VAT. Roof leak investigation starts from £150, including VAT. We confirm the exact price before booking.
