Photos are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe. A typical visit takes about one to two hours for a house, though large, tall or awkward roofs take more time. A survey in Hertford needs access inside and out, including the loft hatch and any rooms with damp. If there’s a side gate or a rear garden, let us know how to reach it. Weekday and weekend visits are available.
- You let us know where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- From the loft space, we trace the water’s route where there is safe access.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe viewpoint.

Advice
Roof leak investigation in Hertford
Older homes have more places for water to get in. Lead flashings crack or lift, valley linings wear and parapet gutters overflow when outlets block. If your home has a butterfly roof, the central valley gutter is a common culprit. Parapet walls and their gutters are looked at from wherever it is safe. Our report shows what we found, with photos. Common reasons to book are damp ceilings under a flat roof and staining where a gutter or parapet meets the wall, on rooflights and dormers, slate and tile slopes and valleys and parapet gutters.
Around a town like Hertford, leaks come from older and newer roofs alike. On older roofs it is often slates, mortar and lead that has split or lifted; later homes can leak at valleys, verges and flat roofs over extensions. Knowing the cause tells you what to do next. It also helps show whether the problem is long-standing wear or recent damage.
The report works through the roof section by section, from the coverings down to the gutters. You will see the good as well as the bad.

Landlords, agents and block managers in Hertford
Any of our surveys can be booked by landlords, agents and building managers in Hertford. For a price for a let property or a block, phone 07833 053749 or drop us an email.
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Mention it when you get in touch and we’ll plan the visit with that in mind.
Before and after the survey
These tips come from what we see on roofs every week, before and after a survey:
- Catch drips in a bucket and protect the floor
- Photograph the stain each time it appears
- Do not climb onto the roof to look
- Check the loft is accessible
If the leak turns out to be condensation, the report says so, and suggest how the roof space could be better ventilated. That avoids roof work that wouldn’t help.
Keep the roof space ventilated. Good airflow reduces condensation, which is frequently mistaken for a leak. Check insulation doesn’t block airflow at the eaves.
Why get it checked now?
Water damage grows the longer it’s left. Wet timbers start to decay, plaster softens and insulation stops working. Tracing it now means less to put right later. Around Hertford, water from a roof defect frequently goes unseen for a while, such as the loft insulation, the top of a wall or the roof timbers. By the time it shows inside, the job has grown.

Questions from Hertford
Does a conservation area affect roof work in Hertford?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Is Hertford in the area you cover?
Yes. We cover the whole of London and South East England, and Hertford is part of that. Just call 07833 053749 or use the contact form and tell us about the property, and we’ll talk through which survey suits.
Can you inspect my roof with a drone?
Yes, where it’s applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed.
What happens next?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
How should I prepare for the leak investigation?
Keep a note of when it leaks, and take photos. Move stored items away from the loft hatch. Keep away from any light or socket that water is reaching.
Are you insured?
We hold professional indemnity and public liability insurance, for every survey we carry out.

Leaks and storm damage in Hertford
Before planning roof work on an older home, find out whether it’s listed or in a conservation area. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Each of these roof types has its own typical places for water to get in.
Hotels and guest houses near Hertford cannot easily close rooms for a leak, so it’s worth knowing the roof’s condition. Take a building like Mill Mead Primary School: on a building that size, finding the source of a drip means looking well beyond the stain.

What you can safely check yourself
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
Common roof problems in Hertford
Slipped or missing slates and tiles let rain reach the underlay. Old bitumen felt may cope for a while, but it tears and sags with age, while some very old roofs have nothing under the coverings. On slate roofs, slipping is often caused by corroded nails.
Look out for signs like these:
- Staining around the chimney inside
- Damp ceilings under a flat roof
- Brown rings on upstairs ceilings
- Water coming in around a roof light or dormer
If you let a flat or house near Hertford East station, tracing a leak quickly matters when a tenant is living with it.
