Flat roof surveys for homes and businesses in Hanger Hill
Buying a home with a flat-roofed extension, dormer or garage? It helps to know that roof’s condition before you exchange. Felt roofs often last around 15 to 20 years, while EPDM and GRP often last longer. We set out the type of covering, its condition and the defects we found, with a photo of every defect. That gives you facts to raise with the seller or agent. We survey upstands and outlets, single-ply membranes and felt flat roofs, and people most often book us about ponding water that doesn’t drain away and loose or cracked edge trims.
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, each with its own weak points. In Hanger Hill, as anywhere in London, the right approach depends on what the roof is made of. Many older flat roofs are felt or asphalt, and many newer ones EPDM rubber or GRP.
We keep jargon out of it: where something needs attention, it says so plainly, along with how urgent it is.

Before and after the survey
From years of surveys, a few habits stand out:
- Plan a survey before the covering reaches the end of its usual life
- Limit foot traffic on the covering
- Clear roof outlets and gutters each autumn
- Check new fixings through the roof are properly sealed
Many people send the report to two or three roofers for quotes. With each roofer working from the same list, comparing quotes is simpler. You stay in control of who does the work and when.
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.
What happens on the day
After the inspection, everything we found is written up as a written report with photos, emailed to you. On timing, most surveys take about 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Hanger Hill runs like any other.
- We start with the address and, on larger roofs, the roof area and access.
- We check the rooms or spaces under the roof for staining where there is access.
- We view the roof from safe positions and never walk on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
Before we arrive
- Let us know about parking near the property
- Leave side gates unlocked

Advice
Surveys for landlords and agents in Hanger Hill
We survey roofs for letting agents and landlords as well as householders. The report gives you a dated record of the flat roof, with photographs, useful for planning maintenance.
Businesses and commercial landlords can book us too, including offices, shops and units. Bigger roofs take more time, and they’re priced for the size.
What we can’t see
A survey is a careful look at the flat roof, but it cannot do everything. The main limits are:
- Parts of the roof that aren’t safe to walk on or view
- What’s under the membrane without opening it up
- A structural engineer’s assessment of the deck
If you’re not sure which survey you need, phone 07833 053749 or send us an email and we will give you a straight answer. What our survey covers.

How the survey changes by roof type
Single-ply membranes
Many offices, units and newer flats have a single-ply PVC or TPO roof. The survey looks at welded seams, edges, fixings and signs of damage.
Felt and built-up roofs
A felt roof often lasts around 15 to 20 years, though quality and upkeep make a big difference. Our report sets out its condition and the areas most at risk.
Can I check my roof myself?
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. Never climb onto the roof to look.
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
Your questions about flat roof surveys in Hanger Hill
How do I find out if my home in Hanger Hill is listed?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Will parking be an issue for a roof survey in Hanger Hill?
Parking in Hanger Hill, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
What insurance do you have?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when booking.
How many years has my flat roof got left?
We do not 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.
What’s the best way to book?
It’s easiest to call 07833 053749 or email us. Give us the address and a few details about the roof. Surveys run on weekdays and at weekends.
What happens next?
You’ll get the report by email. With Standard there’s a follow-up consultation; with Premium, an in-person consultation, so you can talk the findings through.
Local flat roofs in Hanger Hill
About 1.2 miles south-west lies Pitzhanger Manor, a reminder of how long the area around Hanger Hill has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area. Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
For hotels and guest houses around Hanger Hill, a roof problem found early is far less disruptive than one found by a guest. Anyone responsible for a site like Holy Family Catholic Primary School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. For businesses in and around places such as London Designer Outlet, outlets and upstands on commercial flat roofs are the places to check before trouble starts.
