About our roof leak investigation in Potters Bar
We use moisture detection and thermal imaging where they help. Moisture detection confirms where timbers, plaster or insulation are damp. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so its findings are checked with moisture readings. Moisture detection is included in the Standard Survey, and thermal imaging in Premium. The best thermal results come after a sunny day, with a dry roof and little wind. Common reasons to book are damp on a chimney breast and stains around a skylight, on flat roof details, lead flashings and chimney stacks.
When a storm passes over a town like Potters Bar, loose tiles, slates and ridges are the first to move. Many policies treat gusts of about 55 mph as storm conditions, though it varies. Photos and a written account help you show what happened, whether to an insurer or a roofer. Policies typically exclude wear and tear, which is why the age of the damage matters.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Different roofs, different checks
Slate and tile slopes
‘Nail fatigue’ is a common cause of slipped slates. Even a single gap can let water in, particularly in driving rain.
Chimney stacks
We look at the outside of the stack and the breast inside, not a flue, gas or sweep inspection.
Common roof problems in Potters Bar
A gutter that overflows can soak a wall and mark the ceiling inside. Hidden gutters behind parapets cause the most trouble, since a blocked outlet sends water over the lining and into the building.
Common reasons to book include:
- Brown rings on upstairs ceilings
- Drips from nail tips in a cold loft
- A leak that comes and goes with the weather
- Water dripping from rafters or underlay
If you live in an older home near St. Mary's Church, old mortar, worn lead and slipped slates are the usual suspects when water gets in.
What to check before booking
- What the survey won’t cover
- Will the report include photos?
- Whether VAT is in the quoted price
- Whether the loft space is looked at, where there is one
What happens on the day
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. All in, the survey typically takes about 1–2 hours for most homes, though a hard-to-trace leak can take longer. In Potters Bar, parking is rarely complicated, though it’s useful to know about driveways or restrictions. We look at the roof from ground level and from windows, then from the loft where there is safe access, and from the roof itself where it’s safe.
- You tell us where the water shows and when it appears.
- The visit starts indoors, at the stain and in the loft.
- 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.
Before we arrive
- Buyers: confirm access with the estate agent or seller
- Leave side gates unlocked
- Agree roof access with the managing agent if it’s shared

FAQs for Potters Bar
Is there anything to prepare before you come to Potters Bar?
It helps to clear access to the loft, and to let us know about leaks, damp patches or recent work. Parking and access details for Potters Bar help us plan the visit.
Do you carry out roof surveys in Potters Bar?
Yes, Potters Bar is within the area we cover. We work right across London and South East England. Just call 07833 053749 or send us an email and let us know about the property, and we’ll talk through which survey suits.
What happens next?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Can you survey at the weekend?
We survey seven days a week: weekdays, Saturdays and Sundays. Just tell us the days that suit you.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Do you climb onto every roof?
Only where it is safe to do so. We inspect what can be seen safely: from ground level, from windows, from inside the loft space, from the roof where it’s safe and by drone where it applies. Anything we can’t see is noted in the report.
How much does a roof leak investigation cost in Potters Bar?
Roof leak investigation starts from £150, including VAT. You will know the price for the job before booking, based on the roof’s size, access and package. For a price, ring 07833 053749 or use the contact form.
Tips that help
Most of what helps is simple and safe from ground level. A few suggestions:
- Catch drips in a bucket and protect the floor
- Keep a photo record of the damp patch
- Don’t climb onto the roof to look
- Note the weather when the leak shows
Keep the report after the work is done. If water appears again, it shows what was found before.
Plan a roof survey every few years. Flashings, valleys and flat roof details are frequent weak points, and catching wear early keeps water out.

Why it’s worth a survey now in Potters Bar
Patching the spot above the stain often does not work. Because water travels, the real entry point may be somewhere else. An investigation finds the likely cause first, so the repair is aimed at the right place. Roof faults found early can be planned for, while one found after water comes through typically has to be dealt with in a hurry, in Potters Bar as anywhere.
Prices start from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we will tell you which fits.

Potters Bar roofs and the weather
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Different coverings let water in at different points, which shapes where the search starts. With Wyllyotts Manor about 0.4 miles west, Potters Bar sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area.
Landlords with a home close to Potters Bar station may find that a tenant living with a leak needs the cause found, not just the stain painted over. Anyone responsible for a site like Ladbrooke Junior Mixed and Infant School will know that water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
