Roof leak investigation in Borehamwood
We investigate roof leaks in Borehamwood and across London and South East England. We visit on weekdays and at weekends. The investigation covers inside and out, from the stain to the likely entry points. The findings come in a written report with photos. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, and then phone 07833 053749 or drop us an email to arrange a visit. We’re often asked to look into stains around a skylight and damp patches next to the stack, on slate and tile slopes, flat roof details and lead flashings.
Around a town like Borehamwood, leaks come from older and newer roofs alike. On older roofs it’s 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 tells you whether the problem is old wear or something more recent.
After the visit, you get a written report with photos, emailed to you. It sets out the condition of the leaking roof, any defects and our written recommendations.

Common roof problems in Borehamwood
Valleys carry a lot of water. Split linings, slipped valley tiles or debris can push water under the slates or tiles. The stain may appear well away from the valley itself.
Things that frequently lead to a survey include:
- A leak that comes and goes with the weather
- Water coming in around a roof light or dormer
- Damp on a chimney breast
- Drips from nail tips in a cold loft
If you live in an older home near All Saints church, old mortar, worn lead and slipped slates are the usual suspects when water gets in.
Questions to ask before you book
- Whether the loft is part of the inspection
- Their drone registration, if they fly one
- What experience they bring
- Their report turnaround times
Questions from Borehamwood
Do you cover Borehamwood?
Yes, Borehamwood is within the area we cover. We cover the whole of London and South East England. You can ring 07833 053749 or send us an email with the address and a few details.
What do I need to do before a survey in Borehamwood?
Mostly, it’s about access: the loft hatch, any locked gates and where to park in Borehamwood. Let us know about known leaks or past repairs as well.
What’s in the report?
A report with photos, covering the condition of the leaking roof, the defects we found and what we recommend, by urgency where it matters. Standard adds moisture detection and a structural check; Premium adds thermal imaging, drone inspection where applicable and structural analysis.
Is there anything I need to do ahead of the visit?
Clear the loft hatch so we can get into the loft space. Have any photos of the leak ready, and let us know about past repairs. In the meantime, catch the water and keep it clear of lights and sockets.
Do you test for asbestos?
No. Asbestos surveys and testing are not part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings.
Do you use drones?
Yes, where applicable and safe. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). It is included in the Drone Roof Survey and, where applicable, the Premium Survey.
How long does a roof leak investigation take?
On site, it normally takes between one and two hours for most homes, though a hard-to-trace leak can take longer. Report times depend on the package.

Roof leak investigations in Borehamwood: local notes
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Each of these roof types has its own typical places for water to get in. With Wyllyotts Manor about 4.3 miles north-east, Borehamwood sits in an area with a long building history. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
If you look after a building such as St Teresa Catholic Primary School, tracing a leak on a big roof starts with where the water appears and works back. If you run a business near Spires Shopping Centre, finding where water is getting in quickly keeps disruption down.

What we look for on each type of roof
Lead flashings
Wherever a roof meets a wall or stack, a flashing keeps rain out. We check for lead that has lifted, split or slipped, and for flashings that have been patched with bitumen.
Parapet and box gutters
Some older terraces have a butterfly roof with a valley gutter in the middle. Problems there often show in the rooms on the top floor.
DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
What a roof leak investigation does not cover
We only report everything that’s safely in view on the day, so there are some things a survey can’t cover:
- A promise to find every leak on a single visit
- What’s under the covering or behind the plaster
- Plumbing leaks that look like roof leaks
If in doubt, ring 07833 053749 or email us and we’ll recommend the right survey. What our survey covers.
What we look at
- Chimney stacks
- Valleys and parapet gutters
- Slate and tile slopes
- The roof space
- Flat roof details
- Rooflights and dormers
- Lead flashings
How it works
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes between one and two hours at most homes; commercial roofs usually need 3–4 hours. If you have questions on the day, just ask. For a home in Borehamwood, the main things we need are a way into the loft, a route to the back garden and somewhere to park. If you will not be there yourself, let us know who will let us in.

- A visit is booked for a weekday, Saturday or Sunday.

Why act early in Borehamwood
Damp in a ceiling or loft can lead to mould. It’s unpleasant, and it’s harder to deal with once established. Stopping the water is the first step. Once water reaches the loft insulation in a home in Borehamwood, it loses much of its value and is slow to dry. That adds to the bill long before the leak is obvious.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. We’ll give you the figure before anything is booked.
Why book with us
- Plain-English reports with photos
- An independent view of the roof
- Clear package prices, including VAT
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID
