Wind, rain and roofs in Frithsden
Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Knowing the roof type helps narrow down where water may be getting in.
Take an older house close to Church of St Lawrence: lead flashings, valleys and old chimneys are typical places for water to get in. Take a building like Potten End CofE Primary School: on a building that size, finding the source of a drip means looking well beyond the stain. For landlords with property near Berkhamsted station, tracing a leak quickly matters when a tenant is living with it.

About our roof leak investigation in Frithsden
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. We check each likely route and we follow where the evidence leads. Every chimney, dormer and roof light adds more joints to check. We look at all of them, from each safe vantage point. We survey the roof space, lead flashings and rooflights and dormers, and people most frequently book us about brown rings on upstairs ceilings and a leak that comes and goes with the weather.
Roofs in small places like Frithsden frequently stand in the open, where storms hit ridges, verges and chimneys hardest. 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.
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 applicable, structural analysis and an in-person consultation.

What you can safely check yourself
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book and it will help the survey.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
Useful tips for Frithsden property owners
These tips come from what we see on roofs every week, before and after a survey:
- Record whether it leaks in every downpour or only some
- Do not climb onto the roof to look
- Move stored items away from the hatch
- Keep a photo record of the damp patch
We email the report to you, with photographs of what we found. It explains the likely entry point, the route the water takes and our recommendations. Basic reports come within 48 hours, Standard within 24 to 48 hours and Premium the same day.
Look at the roof from the ground after strong winds. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Small faults dealt with quickly rarely become leaks.
What a survey costs
Our packages start from £150, with VAT included. The price for your roof depends on:
- House, block, shop or office
- How many separate roofs there are, like extensions, dormers and garages
- Chimneys, valleys, parapets and other details
- If the survey needs thermal imaging or a drone
Every price we give includes VAT. Our price is from £150, including VAT. We confirm the price for your roof before booking.
Getting in touch
The more you let us know, the easier it is to price the survey. When you contact us, let us know:
- The reason for the survey, such as buying, a leak or storm damage
- The kind of building and roof involved
- Your timetable, such as an exchange date
- Any marks or damp showing indoors
Our price is from £150, including VAT. The exact figure depends on the roof and the package, so ring 07833 053749 or send us an email with the details.
What this survey can’t tell you
Without opening up the roof, some things stay hidden, so a survey has limits:
- Leaks that only appear in weather we cannot recreate
- Defects hidden under coverings or inside walls without opening up
- Leaks from plumbing, tanks or pipework rather than the roof
Not sure which survey suits your roof? You can ring 07833 053749 or drop us an email and we’ll tell you before booking. What our survey covers.

For landlords and managing agents
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Let us know about it as you book and we will plan the survey around it.
Letting agents often book on a landlord’s behalf, and the report can go to both. Access is agreed with the tenant beforehand.
Frithsden: your questions answered
Do you cover smaller places like Frithsden?
Yes, Frithsden is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Do you carry out roof surveys in Frithsden?
Yes. We cover the whole of London and South East England, and Frithsden is part of that. Just phone 07833 053749 or use the contact form and let us know about the property.
Does someone need to be in?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access; we’ll agree the details as you book.
Can a leak be traced on a dry day?
Normally, yes. Damp materials can be found without rain. For leaks that only happen in certain storms, we report the most likely routes.
Do you survey roofs on blocks of flats?
Yes. A shared roof needs access agreed first, with whoever owns or manages the building. Mention it when you get in touch and we’ll plan the survey around it.
What’s the best way to book?
To book, call 07833 053749 or send us an email with the address, the type of property and what’s prompted the survey. We’ll confirm the price and agree a day with you.
Why is the stain in a different place from the leak?
Rain that gets in will run along whatever it lands on. On a flat roof it can travel under the covering before it finds a way through the ceiling. Tracing that path is the heart of a leak investigation.

The survey, step by step
Once we have finished looking, we write up our findings in a report with photos. On timing, most surveys take roughly 1–2 hours, more where the leak is intermittent or the roof is large. Somewhere like Frithsden needs a little journey planning: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- We start with your notes and photos of the leak.
- We examine the damp area and the rooms near it.
- From the roof space, we trace the water’s route where there’s safe access.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- We email a written report showing where the water most likely gets in.
How to prepare
- Let us know about parking near the property
- Unlock side gates and any roof access doors
- Have any paperwork from past roof work to hand
