About our roof leak investigation in Great Wymondley
Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that don’t drain. Ponding water makes any weakness worse. We look at the roof surface and the ceiling below to narrow it down. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt often lasts around 15 to 20 years, so age is part of the picture. If you’ve noticed condensation that looks like a leak and brown rings on upstairs ceilings, a survey will tell you what’s going on, on slate and tile slopes, rooflights and dormers and chimney stacks alike.
In a village or hamlet like Great Wymondley, older cottages and farmhouses frequently have roofs that have been patched over many years. A new leak may be fresh damage or the latest sign of long-term wear, which matters if you’re thinking of an insurance claim. The report says what was seen and what it points to. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
We keep jargon out of it: where something needs attention, it says so plainly, and where it can wait, that’s said too.

What affects the price in Great Wymondley
What a survey costs depends on the time and equipment it needs. The main factors are:
- Extensions, dormers and garages with roofs of their own
- The shape of the roof and its details
- Any need for thermal images or a drone flight
- Basic, Standard or Premium
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, all inc. VAT. What your roof costs depends on its size, access and what you want to find out.
What we need to know
Here’s what helps us most when you get in touch:
- Any marks or damp showing indoors
- How the loft is reached, if there is one
- What kind of property and roof it is
- Any photos you have, taken from ground level or a window
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. Otherwise, simply phone 07833 053749 or drop us an email whenever suits you.
When you need someone else
A survey is a careful look at the leaking roof, but it can’t do everything. Its limits include:
- An intermittent leak that shows no trace on the day
- The repair itself (the investigation finds and reports the cause)
- Defects hidden under coverings or inside walls without opening up
If in doubt, ring 07833 053749 or email us and we’ll recommend the right survey. The full list of what we check.

FAQs for Great Wymondley
Is Great Wymondley within the area you cover?
We do. Villages and rural addresses get the same survey as a town house.
Is my home in Great Wymondley listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is frequently shared, so we need permission from whoever owns or manages the building. We inspect only the parts we’re allowed to reach.
How long have you been surveying roofs?
More than 5,000 surveys over 20+ years.
How soon will I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed, ready to forward.
Is the repair included in the leak investigation?
Our job here is to trace the leak and explain it, and the repair is separate. The report gives any roofer a clear brief.
Do you test for asbestos?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
The survey, step by step
Safety comes first on every visit. Everything that can be seen safely is inspected, and anything we cannot see is noted in the report. Most visits take an hour or two at a typical home, and more on a big or complicated roof. Around Great Wymondley, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- You get in touch with details of the leak and any photos.
- Inside, we check the damp area and the roof space above it.
- Likely entry points outside are checked, from flashings and valleys to gutters and outlets.
- Moisture readings and thermal imaging are used where they help.
- We email a report with photos, the likely entry point and recommendations.
Before the survey
- Make a note of anything you’d like us to look at
- Agree roof access with the managing agent if it is shared
- If it isn’t your property yet, arrange access through the agent

Great Wymondley roofs and the weather
About 4.9 miles south lies Knebworth House, a reminder of how long the area around Great Wymondley has been built on. 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. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Knowing the roof type helps narrow down where water may be getting in.
Anyone responsible for a site like Wymondley Junior Mixed and Infant School will know that a leak through a large roof is often found some distance from where the water shows inside. If you let a flat or house near Hitchin station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. If you live in an older home near Church of St Mary the Virgin, old mortar, worn lead and slipped slates are the usual suspects when water gets in.

Can I check my roof myself?
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
Before and after the survey
From years of surveys, a few habits stand out:
- Tell us about any past repairs to the roof
- Mention any plumbing above the damp area
- Clear the loft hatch so we can get in
- Take dated photos of the leak
If there are several possible sources, we list them in order of likelihood. Recommendations are prioritised by urgency where relevant, so you know what to deal with first.
Keep the loft space ventilated. Good airflow reduces condensation, which is often mistaken for a leak. Keep insulation clear of the eaves.
