Roof Leak Investigation in Stanborough
Roof leak investigations in Stanborough and the rest of Hertfordshire. We survey on any day of the week.
- Leaks below a flat extension roof
- Wet patches high on an inside wall
- Damp patches next to the stack
Practical tips
From years of surveys, a few habits stand out:
- Keep water away from lights and sockets
- Mention any plumbing above the damp area
- Protect furniture and flooring under the leak
- Take dated photos of the leak
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. Air movement keeps condensation down, and condensation is a common false alarm. Keep insulation clear of the eaves.
Roof leak investigation in Stanborough
Some leaks only appear in certain weather. Driving rain from one direction, melting snow or a gutter that overflows in a downpour can all set it off. Notes on when it leaks, and what the weather was doing, help us, along with any photos you’ve taken. We look for the clues it leaves behind, like tide marks, stained timbers and damp underlay. Moisture detection shows which materials are still damp. If you’re worried about leaks that appear only in driving rain and water coming in around a roof light or dormer, a survey will tell you what’s going on.
Being in a small place like Stanborough makes no difference to how a leak or storm damage is looked at: we simply plan the journey and access ahead. Tell us where the water shows, when it appears and anything you’ve noticed outside, plus any earlier repairs. If you have photographs of the water coming in, they help as well.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

What we do, step by step
Where it’s 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. The whole visit typically takes about 1–2 hours for a house, rising to roughly 3–4 hours on a commercial building. Rural addresses near Stanborough can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- You let us know where the water shows and when it appears.
- Inside, we check the damp area and the loft space above it.
- Outside, we check every likely route in.
- We use moisture detection, and thermal imaging where it’s useful.
- You receive a written report with photos showing the likely source and what needs attention.
Before we arrive
- Agree roof access with the managing agent if it is shared
- Mention any parking restrictions on your street
- Unlock side gates and any roof access doors

Advice
For landlords and managing agents
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Mention it when you contact us and we’ll plan the visit with that in mind.
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
Stanborough roofs and the weather
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Knowing the roof type helps narrow down where water may be getting in. Hatfield, which Stanborough is part of, is one of England’s post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Low pitches let wind-driven rain reach further under the tiles, and flat-roofed garages and porches are common leak points.
Anyone responsible for a site like Stanborough School will know that tracing a leak on a big roof starts with where the water appears and works back. If you look after a shop, office or commercial unit, for instance near Howard Centre, a quick answer on where water is coming in keeps a business running.
Stanborough is about 2 miles south-west of Welwyn Garden City, in Hertfordshire. We carry out roof leak investigations for homeowners, landlords and businesses in Stanborough. Our area takes in places right across Hertfordshire, large and small. You can also see our page for London.

We also work in nearby towns such as Watford (11 miles south-west), Hemel Hempstead (10 miles west), Stevenage (9 miles north), St Albans (5 miles south-west), Harpenden (6 miles west) and Hitchin (11 miles north).

FAQs for Stanborough
Is Stanborough within the area you cover?
Yes, Stanborough is covered. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Are flat-roofed garages and porches in Stanborough worth including?
It’s often worth it, as these roofs are easy to forget. On buildings from before 2000, cement sheet roofs may contain asbestos and should be checked by a specialist asbestos surveyor before anyone disturbs them.
Is this a RICS survey?
No. We check the roof, not the whole building, so it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
Do you climb onto every roof?
Not always. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the loft space and a drone where applicable.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing aren’t part of what we do. We flag materials that could contain asbestos, like cement sheets or soffits on pre-2000 buildings, and recommend a specialist asbestos surveyor checks them before they’re disturbed.
Can you survey a shared roof?
Yes. A shared roof needs access agreed first, with the freeholder or managing agent. Tell us about it when booking and we will explain what’s needed.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when booking.
What this survey can’t tell you
No survey can tell you everything, and it is better to know them up front. Keep these in mind:
- The repair itself (the investigation finds and reports the cause)
- Leaks from plumbing, tanks or pipework rather than the roof
- Leaks that only appear in weather we cannot recreate
If in doubt, call 07833 053749 or drop us an email and we will suggest the right survey. What our survey covers.

- Anything about access we should know
- Photos of the roof, taken safely from ground level or a window

Do you need a roof leak investigation in Stanborough?
Every flat roof covering has a working life. A felt roof often lasts around 15 to 20 years, and splits, blisters and lifting laps let water in. Upstands and outlets are common weak points.
A survey makes sense if you’ve noticed:
- Damp underlay across a wide area
- Water dripping from rafters or underlay
- Stains around a skylight
- Leaks that appear only in driving rain
For an older house near a landmark such as Church of St John the Evangelist, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.
Before booking any roof surveyor
- Whether they hold professional indemnity and public liability insurance
- What follow-up you get after the report
- Which parts of the roof they’ll actually see
- Whether VAT is added on top
