Stroud Green questions
Is parking a problem for a survey in Stroud Green?
Typically it’s manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
Is Stroud Green in the area you cover?
Yes. We survey roofs across London and the South East, and Stroud Green is part of that. Just call 07833 053749 or email us and let us know about the property.
Do you look in the loft space?
Where it is relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch, and if the loft can’t be reached safely, the report says so.
How long will testing take?
It usually takes more time on a big roof than a small one, with the construction of the roof playing a part too.
What’s the price of ELD?
We quote for each roof individually. Send us details of the roof. Just ring 07833 053749 or use the contact form for a quote.
Does ELD include fixing the breach?
No, our part is finding the breaches. The report gives your roofer the locations.
What does the report include?
It works through the roof part by part, in writing and with photos, finishing with recommendations. The most urgent items are made clear.
About our electronic leak detection in Stroud Green
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current that passes through the membrane only where there is a breach. It can find holes too small to spot by eye so your roofer knows exactly where to repair. The results come in a report with photos. If you’ve noticed leaks showing away from the breach and water coming in under a flat roof, we can find out what’s behind it, whatever the roof.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. Which one is on a roof in Stroud Green shapes how it’s checked. Older flat roofs are frequently felt or asphalt, newer ones rubber or GRP.
Every survey ends with a written report, with photographs, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Leave it or get it looked at?
Water trapped under a membrane can soak insulation and decking. Finding the breach sooner limits that. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Dealing with it early is far less disruptive.
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.

What a survey costs
Several things affect the price of a survey:
- How big the roof is
- Whether it is a home or a commercial building
- Features like valleys, chimneys, dormers and parapets
- Whether thermal imaging or a drone is needed
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.
Helping us price your survey
To price your survey accurately, we’ll ask about:
- The reason for the survey, such as buying, a leak or storm damage
- Where any leaks, stains or damp patches show inside
- Pictures of the roof from a safe spot, if you have them
- When you need the report by
We survey roofs on any day of the week. To find a date that works for you, phone 07833 053749 or use the contact form.
What we can’t see
Our findings are based on what we can see safely on the day, so there are some things a survey cannot cover:
- Fixing the holes we find
- Leaks from walls, copings or rooflights
- Areas we cannot reach or that can’t be tested

What electronic leak detection 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. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. Historic houses such as Witanhurst, about 1.9 miles west, show how far back building in the area around Stroud Green goes. If your house is among the older ones, expect a mix of original materials and later repairs on the roof.
For an older house near a landmark such as Holy Trinity, the flat roofs on later extensions tend to wear out long before the main roof. Controlled parking zones are common in London, so mention any permit rules for Stroud Green. If you own a rental within reach of Harringay station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Can I check my roof myself?
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, which helps when we check the roof.
What we do, step by step
Once we have finished looking, we write up our findings in a report with photos, emailed to you. As for time on site, most surveys take a length of time set by the membrane area and the build-up, which we set out in the quote. London terraces rarely offer a view of the whole roof from one spot, so in Stroud Green we work round the house, using the street, the windows, the loft and any safe vantage point behind it. If other people live in the building, tell us who can let us into the shared parts.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Before we arrive
- For a flat or shared roof, check access with the building owner or managing agent
- Buyers: confirm access with the estate agent or seller
- Check pets are kept safely away
