About our flat roof survey in Pentonville
Each type of flat roof has its own weak points. Felt can blister and crack, asphalt can craze and split, EPDM seams and laps can lift, and GRP can crack where boards meet or at the trims. Single-ply PVC and TPO roofs are checked at their welds, edges and fixings. Knowing what you have and how it is doing helps you plan what comes next. If you’ve noticed blisters and bubbles in the covering and leaks around rooflights, we can find out what’s behind it.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Pentonville, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Should I look at the roof myself first?
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.
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Practical tips
A little preparation and a few simple habits help, both for the survey and for the roof itself. Some pointers:
- Keep outlets clear of leaves and moss
- Keep clear of rooflights and fragile roof sheets
- Ask whoever fits equipment on the roof to make good the covering
- File the paperwork for the roof and any repairs
The report is emailed to you, ready to share with a roofer, the seller or a managing agent. It’s written in plain English, with a photo of each defect, so others can follow it without going up to look.
Keep outlets, gutters and hoppers clear, particularly after the leaves fall. Water that can drain away does far less harm than water that sits.
How the survey works
The visit has one job: to look at the flat roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It usually takes between one and two hours for a small flat roof at home, and longer for a large commercial one. In converted houses and mansion blocks, the loft hatch is often on a shared landing. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Pentonville runs like any other.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there is access.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- You get a report setting out the condition and our recommendations, in order of urgency.
Getting ready for the survey
- Buyers: confirm access with the estate agent or seller
- Check we can get to the back of the property
- Dig out any old roof reports or invoices

Pentonville: your questions answered
Will parking be an issue for a roof survey in Pentonville?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
How do I find out if my home in Pentonville is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
What does a roof survey cost?
Our price is from £150, including VAT. You’ll know the exact price before booking, and it depends on the roof’s size, access and the package you choose. To get a price, phone 07833 053749 or drop us an email.
What happens next?
You will receive the report by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Do you carry out surveys on Saturdays and Sundays?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when you book.
Do you look in the loft space?
If the survey needs it and the roof space can be reached safely, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach.
How we price flat roof surveys
A few things affect what a survey costs:
- How complicated the roof is, with its valleys, chimneys and parapets
- Building height and the viewpoints available
- Basic, Standard or Premium
- If the survey needs thermal imaging or a drone
Our price is from £150, including VAT. The final price depends on the size and height of the roof, how it can be seen safely and which survey you book.
Helping us price your survey
A little information up front helps. It’s useful to include:
- Any marks or damp showing indoors
- Pictures from the garden or a window, if you have them
- Your postcode, so we can check access and travel
- Any deadline, like an exchange date
We confirm the price for your roof before booking, so you know the cost up front. Prices start from £150, including VAT. To book, call 07833 053749 or send us an email.
Landlords, agents and block managers in Pentonville
Any of our surveys can be booked by landlords, agents and building managers in Pentonville. For a price for a let property or a block, phone 07833 053749 or email us.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out in order of urgency where relevant.
What we cannot see
We only report what can be seen safely on the day, so there are some things a survey can’t cover:
- Fragile surfaces, which we do not walk on
- A structural engineer’s assessment of the deck
- Testing older roof sheets for asbestos
Not sure which survey suits your roof? You can call 07833 053749 or email us and we will tell you before you book. The full list of what we check.

Flat and commercial roofs around Pentonville
Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. If your home in Pentonville is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. With Dr Johnson's House about 1.4 miles south, Pentonville 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.
A roof leak in a hotel or guest house around Pentonville means lost rooms as well as repairs. If you run a business near Brunswick Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling. For an older house near a landmark such as Church of Saint Peter, flat-roofed rear additions and dormers added over the years are worth checking.
