Roof leak investigation in Gosmore: what you get
We use moisture detection and thermal imaging where they help. Moisture readings show which materials are wet. A thermal camera shows patterns of temperature rather than water, so we confirm what it suggests with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. Thermal imaging works best after a sunny day, on a dry roof with little wind. We survey valleys and parapet gutters, the roof space and slate and tile slopes, and the problems we are asked to look at most are wet patches high on an inside wall and damp ceilings under a flat roof.
Roofs in small places like Gosmore often 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.
Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

How the survey works
The visit has one job: to see as much of the leaking roof as can be seen safely and record it clearly. Everything we note and photograph goes into the written report. The visit usually takes an hour or two for most homes, though a hard-to-trace leak can take longer. Rural addresses near Gosmore can be hard to find from a postcode alone, so a few directions are welcome. After that, the survey runs as it would anywhere.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Where it’s useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
Getting ready for the survey
- Unlock side gates and any roof access doors
- Gather any invoices or paperwork from past roof work
- If you’re buying, check with the agent that we can get in
Book a survey
If you are buying, it helps to book soon after your offer is accepted, so there is time to use the report before exchange. For any other survey, just ring 07833 053749 or send us an email when you are ready.
Advice
Practical tips
You do not need to be a roofer to help. What helps most:
- Mention any plumbing above the damp area
- Protect furniture and flooring under the leak
- Have an electrician check any wet fittings
- Mention earlier attempts to fix the leak
If the leak turns out to be condensation, the report says so, with recommendations on ventilation. It saves chasing a leak that isn’t there.
Have flashings and flat roofs looked at every few years. They’re where most leaks start, and wear is easier to deal with before water gets in.

Gosmore: your questions answered
Is Gosmore within the area you cover?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.
Do you cover Gosmore?
Yes. We work right across London and the South East, and Gosmore is part of that. You can call 07833 053749 or use the contact form with the address and a few details, and we will talk through which survey suits.
Is the repair included in the leak investigation?
This service finds and reports the cause, not to carry out the repair. The report gives any roofer a clear brief.
Do you carry out surveys on Saturdays and Sundays?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.
Do you use thermal imaging to find leaks?
We use thermal imaging where it helps, and it’s part of the Premium Survey. It picks up temperature patterns rather than water, so we confirm its findings with moisture readings.
How do I book a survey in Gosmore?
Simply ring 07833 053749 or email us with the address. After a few questions, we confirm the price and fix a day.
Why is the stain in a different place from the leak?
Because water travels. It runs along rafters, battens or underlay before it drips, so the stain may be some distance from where it gets in. That is why we trace the route rather than patching above the stain.
What a survey costs
All our prices include VAT. The things that change the price are:
- Building height and the viewpoints available
- The package you choose: Basic, Standard or Premium
- The number of roofs, including extensions and garages
- The shape of the roof and its details
Prices quoted always include VAT, and the written report is part of the package. Prices start from £150, including VAT. Size, height and access decide where your roof falls.
Booking your survey
When you call or email, these details help:
- The reason for the survey, such as buying, a leak or storm damage
- Your postcode, so we can check access and travel
- Any marks or damp showing indoors
- Pictures from the garden or a window, if you have them
Our phone lines are open seven days a week. To book or ask a question, call 07833 053749 or use the contact form.
DIY checks: what’s safe
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
The one thing to avoid is getting up close. Roofs are fragile and slippery. That is where a survey comes in.
When to book a survey in Gosmore
Flashings are one of the commonest sources of roof leaks. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. When lead lifts or splits, or a mortar fillet cracks, rain runs straight in, often well away from where it shows.
We’re often asked to look at:
- Damp walls below an overflowing gutter
- Damp ceilings under a flat roof
- Damp on a chimney breast
- Water dripping from rafters or underlay
For hotels and guest houses around Gosmore, a roof problem found early is far less disruptive than one found by a guest.
What to check before booking
- What they won’t be able to tell you
- How long the report takes to arrive
- Whether the loft is part of the inspection
- What experience they bring

Wind, rain and roofs in Gosmore
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Where water gets in depends a good deal on what the roof is made of and how it’s detailed. With Knebworth House about 4.7 miles south-east, Gosmore sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
If you own one of the older houses in the streets near Church of St Ippolyts (church of England), water on an older roof tends to find its way in at the lead, the valleys or the chimney. Anyone responsible for a site like St Ippolyts Church of England Aided Primary School will know that tracing a leak on a big roof starts with where the water appears and works back.
