Dedworth roofs and the weather
Historic houses such as St Leonard's Hill, about 0.6 miles south, show how far back building in the area around Dedworth goes. Older homes in the wider area frequently have features worth a closer look, like 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. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Each of these roof types has its own typical places for water to get in.
If you look after a building such as Dedworth Green First School, tracing a leak on a big roof starts with where the water appears and works back. For hotels and guest houses around Dedworth, a roof problem found early is far less disruptive than one found by a guest.
Dedworth is about 1 mile west of Windsor, in Windsor and Maidenhead. From houses to flats and shops in Dedworth, we can survey the roof. Our area takes in places right across Windsor and Maidenhead, large and small. There is also a page for Reading.

How a roof leak investigation works in Dedworth
A leak that comes and goes can be the hardest to pin down. 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 typically leaves clues: stained timbers, tide marks and damp underlay. Moisture detection shows which materials are still damp. If you’ve noticed stains around a skylight and drips in the loft during heavy rain, we can find out what’s behind it, whatever the roof.
In older homes around places like Dedworth, the underlay may be old bitumen felt, or there may be none at all. Without a sound underlay, any gap in the coverings lets water straight through. Whether it is long-term wear or recent damage makes a difference to what happens next. Wet battens and insulation in the loft are often the first clue.
The report does not just list problems. It explains what we found, why it matters and what we recommend.

Leave it or get it looked at?
A small drip today can be a bigger leak after the next storm. Wind lifts loose slates further and gaps widen. Tracing it now lets you plan the work rather than react to it. Homes in smaller places like Dedworth can face more weather, so a loose ridge or verge soon lets rain in. Each storm lifts it a little further.
Prices quoted always include VAT, and the report is not charged as an extra. Roof leak investigation starts from £150, including VAT. Size, height and access decide where your roof falls.

What happens on the day
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, take photos as we go and record our findings for the written report. Most visits take about one to two hours, more where the leak is intermittent or the roof is large. Homes around Dedworth often have gardens on more than one side, which gives us room to step back and see the roof. Mention any side of the property we cannot get to. Inside, the loft is looked at where it can be reached safely.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- You get photos, the likely cause and clear recommendations.
Before we arrive

Your questions about roof leak investigations in Dedworth
Does a conservation area affect roof work in Dedworth?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is Dedworth within the area you cover?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Can thermal imaging help find my roof leak?
Where conditions suit, it can. The best results come after a sunny day, on a dry roof with little wind. Wet insulation holds heat longer than dry, which can show up on the image. Its findings are confirmed with a moisture check.
Can you find a leak when it isn’t raining?
Often, yes. Stains, tide marks, damp timbers and moisture readings normally point the way. Some leaks only show in particular weather, so photos and notes from when it leaks help a lot.
Is this a RICS survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Can you tell me if my roof has asbestos?
No. We don’t sample or test for asbestos. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
How long will you be at the property?
It normally takes roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
What we’re asked to look at in Dedworth
A roof valley collects the rain from two slopes. Worn lead, cracked linings or a build-up of leaves and moss can push water under the slates or tiles. The stain may appear well away from the valley itself.
Signs worth acting on include:
- Brown rings on upstairs ceilings
- Drips in the loft during heavy rain
- Drips from nail tips in a cold loft
- Damp walls below an overflowing gutter
For landlords with property near Windsor & Eton Central station, tracing a leak quickly matters when a tenant is living with it.
Questions to ask before booking
- Will they check the loft as well as the outside?
- What exactly goes into their report
- Whether any drone flown is registered with the CAA
- How they’ll see the roof: from ground level, the loft, the roof or by drone
What this survey cannot tell you
Our findings are based on what we can see safely on the day, so there are some things a survey can’t cover:
- Defects hidden under coverings or inside walls without opening up
- Water from pipes, tanks or heating systems
- Leaks that only appear in weather we cannot recreate
If in doubt, phone 07833 053749 or send us an email and we will point you to the right survey. What our survey covers.
What this survey covers
- The roof space
- Rooflights and dormers
- Flat roof details
- Valleys and parapet gutters

Landlords, agents and block managers in Dedworth
Surveys can also be booked by buyers’ agents acting for a client. Reports are emailed, so they’re easy to pass on, photos included.
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Tell us about it when you book and we will plan the visit with that in mind.

Useful tips for Dedworth property owners
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Tips:
- Clear the loft hatch so we can get in
- Keep water away from lights and sockets
- Keep a photo record of the damp patch
- Note the weather when the leak shows
If the leak turns out to be condensation, the report says so, and suggest how the loft space could be better ventilated. That avoids roof work that wouldn’t help.
Have leaves and moss cleared from gutters, valleys and outlets, ideally once the leaves have fallen. Many leaks start with a blocked outlet. Use a professional rather than climbing up yourself.
