What a roof leak investigation looks like in Stroud Green
Many homes in inner London are Victorian and Edwardian terraces, frequently with Welsh slate roofs. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Knowing the roof type helps narrow down where water may be getting in. With Witanhurst about 1.9 miles west, Stroud Green sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
If your home is one of the older ones in the streets near Holy Trinity, water on an older roof tends to find its way in at the lead, the valleys or the chimney. If you let a flat or house near Harringay station, a tenant living with a leak needs the cause found, not just the stain painted over.

Roof leak investigations for homes and businesses in Stroud Green
We investigate roof leaks in Stroud Green and across London and South East England. Surveys are carried out on weekdays and at weekends. The investigation covers inside and out, from the stain to the likely entry points. You get a photo-illustrated written report and recommendations. If water is coming in now, catch it in a bucket and keep it away from lights and sockets, then ring 07833 053749 or drop us an email to arrange a visit. We survey lead flashings, chimney stacks and the roof space, and people most often book us about water through the ceiling under a flat roof and staining around the chimney inside.
Many London homes are well over a century old and their roofs have been patched more than once. Telling wear from a one-off event matters, because insurers typically exclude wear and tear. A careful look in Stroud Green tells the two apart where the evidence allows. Photos and a written account give you something specific to show an insurer, a landlord or a roofer.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

What affects the cost of roof leak investigations
Survey packages start from £150, including VAT. What you pay for your roof depends on:
- The number of roofs, including extensions and garages
- The shape of the roof and its details
- Which survey package you book
- Whether it’s a home or a commercial building
A Basic Survey starts from £150, with VAT included. Standard is from £250 and Premium from £400, both inc. VAT. We confirm the exact price before you book.
Getting in touch
Here’s what helps us most when you get in touch:
- Where the property is, with the postcode
- Any photos you have, taken from ground level or a window
- Dates you’re working to, such as exchange
- The reason for the survey, such as buying, a leak or storm damage
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply phone 07833 053749 or use the contact form whenever suits you.
Tips that help
A little preparation and a few simple habits help. Our tips:
- Note the weather when the leak shows
- Tell us about any past repairs to the roof
- Don’t climb onto the roof to look
- Put a bucket under the drip and move valuables
Keep the report after the work is done. If the leak returns, it is a useful record of what was found, which makes the next step quicker.
After a downpour, look in the roof space with a torch, keeping to boarded areas. Watch for water marks, wet underlay and damp wood. Take photos of anything that changes.
Signs you need a roof leak investigation in Stroud Green
Blocked gutters can look like a roof leak. Hidden gutters behind parapets cause the most trouble, because when they block, water backs up and runs inside.
Here are some of the things we see often:
- Damp underlay across a wide area
- Water coming in around a roof light or dormer
- A leak that comes and goes with the weather
- Drips in the loft during heavy rain
If you run a business near The Mall Wood Green, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
Questions to ask before booking
- Will they check the loft as well as the outside?
- Are they insured for the work?
- What exactly goes into their report
- Whether any drone flown is registered with the CAA
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, which helps when we check the roof.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
Why get it checked now?
Damp loft insulation loses much of its value. Insulation can soak up water quietly before anything shows below. The sooner the cause is found, the less needs replacing. Many older London roofs have only old felt under the slates, or no underlay at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
The Premium Survey includes thermal imaging and drone inspection where applicable, from £400 inc. VAT. We will tell you which package suits the questions you have.

Common questions in Stroud Green
Do you carry out roof surveys in Stroud Green?
Yes, Stroud Green is within the area we cover. We work right across London and South East England. Just phone 07833 053749 or use the contact form and let us know about the property, and we will talk through which survey suits.
Does a conservation area affect roof work in Stroud Green?
We cannot 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.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We check the roof, not the whole building, and it isn’t a RICS Level 2 or Level 3 survey. Many buyers have both.
Will you definitely find the leak?
We can’t promise it. Water can travel a long way, and some leaks only show in particular storms. If we cannot be sure, the report ranks the possible sources.
What does a roof survey cost?
Prices start from £150, including VAT. Our Basic Survey starts from £150, the Standard Survey from £250 and the Premium Survey from £400, all including VAT.
Does the investigation include the repair?
Our job here is to trace the leak and explain it, and the repair is separate. With the report, a roofer knows exactly where to look.

What else we do in Stroud Green
How it works
When we arrive, we begin with a quick chat about the roof and anything that’s worrying you. We then inspect everything that can be seen safely. Most surveys take about one to two hours, more where the leak is intermittent or the roof is large. In Stroud Green, as in much of London, plenty of properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when booking.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- We inspect inside and out, starting from the stain.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- The report explains the likely entry point and what needs attention.
Before the survey
- For a flat or shared roof, check access with the building owner or managing agent
- Have any paperwork from past roof work to hand
- Tell us about parking before the day
Booking a survey
