About our flat roof survey in College Park
Standing water is one of the first things we look for on a flat roof. It can point to poor falls, a blocked outlet or a deck that is deflecting. We record where water sits, check the outlets and look for dips that suggest deflection. Where the deck may be a structural issue, our report says a structural engineer should look at it. We survey felt flat roofs, upstands and outlets and single-ply membranes, and people most frequently book us about leaks around rooflights and splits, cracks and crazing.
On a London roof terrace or a flat roof over a back addition, water often runs under the covering before it shows. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a block or conversion in College Park, the flat roof is often a shared part of the building.
The report is written in plain words, so you do not need to be a roofer to follow it. Photographs show what each point refers to, and recommendations are put with the most urgent first where relevant.

What else we do in College Park
Tips that help
You do not need to be a roofer to help. What helps most:
- Note the date and type of any roof work
- Check ceilings under the roof for damp patches
- Check that new brackets or units haven’t damaged the covering
- Check the outlets after the leaves fall
Once we have been, the findings are written up with photos. It covers the type of covering, its condition and each defect, with our recommendations. Turnaround is within 48 hours for a Basic Survey, 24 to 48 hours for a Standard Survey and the same day for a Premium Survey.
Have the roof surveyed every few years, and after any work that goes through it. That catches changes early and builds up a record of the roof.
Roof by roof
Mastic asphalt
Older asphalt can become brittle and crack as the roof moves. We note where this is happening and how widespread it looks.
Rooflights and upstands
Upstands at walls and parapets need to stay watertight as the building moves. We look for splits, gaps and failed flashings over the top.
Leave it or get it looked at?
Standing water on a flat roof rarely sorts itself out. It typically points to an outlet, the falls or a sagging deck, and every wet spell adds to the wear. Knowing the cause early gives you more choice over what to do. Any roof job in College Park means planning around parking, neighbours and access. That is a good reason to find problems early, while there is time to plan, rather than in a rush after a leak.
Prices start from £150, including VAT. What you pay depends on the size and height of the roof, how it can be seen safely and the package you choose.

The survey, step by step
We do not take risks to get a closer look. Everything that can be seen safely is inspected, and anything we cannot see is noted in the report. Most visits take an hour or two 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 is the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in College Park runs like any other.
- You tell us about the roof, its covering if you know it, and any leaks.
- We view the roof from ground level, from windows and from the roof where it is safe to do so.
- The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
- Where there’s safe access, we look at the ceilings and spaces below for signs of water.
- You get a written report with photos and our recommendations.
Preparing for the visit
- Make sure pets are kept safely away
- Have keys ready for side gates, garages or roof access doors
- Let us know where we can park nearby
How to book
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. Otherwise, simply phone 07833 053749 or drop us an email whenever suits you.

Common roof problems in College Park
Many flat roof problems start at the details rather than the main surface. Upstands, edge trims, outlets and the kerbs around rooflights move and weather differently from the rest of the roof. Where they weren’t finished well, they tend to fail before anything else.
Typical things we’re asked to look at include:
- Raised blisters across the surface
- Ponding water that doesn’t drain away
- Outlets choked with leaves and silt
- Cracked or split membrane
A roof leak in a hotel or guest house around College Park means lost rooms as well as repairs, so it pays to find faults before guests do.
Before you book any roof surveyor

- Whether any drone flown is registered with the CAA

What a flat roof survey looks like in College Park
About 2.6 miles south-east lies Leighton House, a reminder of how long the area around College Park has been built on. On older houses around here, roofs frequently 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. There are several hotels within about a mile and a half of College Park. If you look after one, a leak through a flat roof can put a room out of use.
If you look after a shop, office or commercial unit, for instance near Westfield London, flat roofs over shops and units are easy to forget until water comes through a ceiling. If you own one of the older houses in the streets near Saint Mark's, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Your questions about flat roof surveys in College Park
Can you look at the flat roof of a hotel or office near College Park?
Yes, commercial flat roofs are part of what we cover. Larger commercial roofs are quoted for the building.
Is my home in College Park listed or in a conservation area?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
When does the report arrive?
It depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
What’s the best way to book?
To book, call 07833 053749 or use the contact form and let us know the address and what you need to know. We’ll confirm the price and find a day that suits.
Does someone need to be in?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you when booking.
Does the weather affect the survey?
Some surveys depend on the weather more than others. Drones can’t fly safely in strong wind or heavy rain, and thermal imaging works best after a sunny day, with a dry roof and little wind. If the conditions are not right, we will talk to you about another date.
Does this replace a RICS home survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
