Flat roof survey in Farnham: what you get
If the house you’re buying has a flat roof on an extension, dormer or garage, it’s worth knowing its condition before 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 photos of each. You then have something specific to put to the seller or agent. Typical surveys look at blocked or damaged outlets and pools of water lying on the roof, on single-ply membranes, upstands and outlets and mastic asphalt.
Flat roofs on exposed homes in small places like Farnham take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are normally the first part of a flat roof to go.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

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. Notes and photographs go into the written report. The visit typically takes an hour or two at a typical home, while a commercial roof takes nearer three to four hours. Around Farnham, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- 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.
How to prepare
- Make sure pets are kept safely away
- Leave a clear route to the loft
- If the roof is shared, arrange access with whoever manages the building

Local flat roofs in Farnham
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. About 4.2 miles south-west lies Much Hadham Palace, a reminder of how long the area around Farnham has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
If you live in an older home near Church of St Mary the Virgin, the flat roofs on later extensions tend to wear out long before the main roof. Landlords with a home close to Stansted Mountfitchet station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. For site and facilities teams at buildings like Farnham Church of England Primary School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

How the survey changes by roof type
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.
Mastic asphalt
With age, asphalt can harden and crack with movement. The report shows where it’s cracking and how far it seems to extend.
Rented homes, blocks and businesses
Where a roof is shared: we need access agreed with the building owner or managing agent. Mention it when you get in touch and we will plan the survey around it.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out in order of urgency where relevant.
Should I look at the roof myself first?
A lot can be seen 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: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
