Flat roof surveys for homes and businesses in Grahame Park
Standing water is one of the first things we look for on a flat roof. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. Where the deck may be a structural issue, our report says a structural engineer should look at it. We survey upstands and outlets, mastic asphalt and single-ply membranes, and people most often book us about failed seals around rooflight kerbs and damaged trims at the roof edge.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. In Grahame Park, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are frequently felt or asphalt, newer ones rubber or GRP.
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.

What we look for on each type of roof
Felt and built-up roofs
Many extensions, garages and dormers have a felt roof laid in layers. We look for blistering, cracking, split laps and worn mineral surfacing.
GRP fibreglass
Movement in the deck or a thin layer of resin can lead to cracks in GRP. Our report notes cracks and any sign that the deck is flexing.
Can I check my roof myself?
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book, as it helps us focus the survey.
A DIY look is useful, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight.
Why act early in Grahame Park
A leak over an office, shop or unit can affect the people and stock underneath. A planned survey lets you budget for work rather than deal with an emergency around the business. Blocked gutters and hoppers on London houses overflow and soak brickwork. A blocked outlet ignored for a winter or two can mean damp walls inside.
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, all with VAT included. What your roof costs depends on its size, access and what you want to find out.

What affects the price in Grahame Park
We confirm the price for your survey before you book. These are the things that affect it:
- The shape of the roof and its details
- How many separate roofs there are, like extensions, dormers and garages
- The height of the building and how the roof can be seen safely
- If the survey needs thermal imaging or a drone
Thermal imaging and drone inspection (where applicable) come with the Premium Survey, from £400 including VAT. We can help you choose the package that fits what you’d like to know.
What to let us know when you contact us
Getting the details right at the start saves time. It is useful to include:
- Any stains, drips or damp patches you’ve seen indoors
- The address and postcode of the property
- Photos of the roof, taken safely from the ground or a window
- Whether there’s a loft hatch, a shared roof or tricky access
For a price for flat roof surveys in Grahame Park, phone 07833 053749 or send us an email. The address, the type of property and what you’d like to know help us give you an accurate price.
What we do, step by step
We work from the outside in: outside views come first, then the loft space if there is safe access. All told, expect an hour or two for most houses, rising to roughly 3–4 hours on a commercial building. In Grahame Park, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it’s useful to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- Inside, we look for signs of water under the roof where we can reach.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
Preparing for the visit
- If you’re buying, let the agent know when we are coming
- Keep pets out of the way during the survey
- Let us know where we can park nearby
Arrange a survey
If you are buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. For any other survey, just ring 07833 053749 or drop us an email when you are ready.

Your questions about flat roof surveys in Grahame Park
Is my home in Grahame Park listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Will parking be an issue for a roof survey in Grahame Park?
It rarely stops a survey, but it is worth planning. Let us know what parking is available nearby, and the visit is planned around it.
Can you tell me how long my flat roof will last?
We don’t give a fixed number of years, because so much depends on upkeep, exposure and workmanship. Our report describes the condition and what needs doing, and when.
Are you insured?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
How experienced are you?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys.
Does the survey cover asbestos?
We don’t test for asbestos. If we see materials that could contain it, like cement sheets on a building from before 2000, we flag them so a specialist asbestos surveyor can check them.
Can you inspect my roof with a drone?
Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
Local flat roofs in Grahame Park
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Heath Hall, about 3.5 miles south-east, is one of the historic houses in the wider area around Grahame Park. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
Controlled parking zones are common in London, so mention any permit rules for Grahame Park. If you run a business near Broadwalk Centre, flat roofs over shops and units are easy to forget until water comes through a ceiling. If you look after a building such as St James' Catholic High School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
