How a flat roof survey works in Felden
Our flat roof survey checks the waterproof covering and every detail around it, from edges and upstands to outlets and rooflights. Felt, asphalt, EPDM, GRP and single-ply PVC or TPO roofs are all part of the work. It suits a small roof over an extension or garage as well as a large one over flats, offices or units. The findings go into a written report with photos, setting out the defects and what we’d recommend. Common reasons to book are upstands pulling away from walls and blisters and bubbles in the covering, across GRP fibreglass, single-ply membranes and upstands and outlets.
In smaller places like Felden, flat roofs are mostly on extensions, garages, porches and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. Knowing the covering and how it was laid tells you what to expect from it, from felt and asphalt to EPDM rubber and GRP. From an upstairs window, look for standing water, splits and edges coming away.
The report does not just list problems. It explains what we found, why it matters and what we recommend.

Questions from Felden
Are flat-roofed garages and porches in Felden worth including?
Yes, if you’d like it included, mention it when booking. On buildings from before 2000, cement sheet roofs may contain asbestos and should be checked by a specialist asbestos surveyor before anyone disturbs them.
Is my home in Felden listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Do you look for flat roof leaks?
We check the covering and every detail where leaks commonly start, recording anything that could let water through. Where the source is not obvious, a roof leak investigation or electronic leak detection may be the next step.
What does a roof survey cost?
Flat roof survey starts from £150, including VAT. The final figure depends on the roof and the package you choose, and it is agreed before booking.
Is a flat roof survey the same as a building survey?
No. We look closely at the flat roof rather than the whole building. It works alongside a RICS home survey, not instead of one, and structural calculations need a structural engineer.
Do I have to be there for the survey?
Not necessarily. If we only need the outside, we can agree that ahead of time, but anything inside needs someone there to give access.
Does the survey cover asbestos?
Our survey does not include asbestos testing. Buildings built or refurbished before 2000 may contain asbestos, for example in cement roof sheets. We note anything that could contain it, and a specialist asbestos surveyor should check it before it’s disturbed.

Advice
Flat roof surveys in Felden: local notes
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. The wider area around Felden has a long history of building, with High Elms Manor about 3.4 miles south-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
Landlords with a home close to Apsley station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round. Anyone responsible for a site like Nash Mills Church of England Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you live in an older home near Church of St Mary, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Useful tips for Felden property owners
A survey works best with a little help from you, before and after. Tips:
- Ask contractors to protect the roof if they work on it
- Never stand on rooflights or fragile sheeting
- Check ceilings under the roof for damp patches
- Have the roof looked at again after a severe storm
If you are buying, the report gives you something specific to take back to the seller or agent. You might ask for work to be done before completion, or discuss the price, depending on the findings.
Keep foot traffic on a flat roof to a minimum. If access is needed, boards or walkways help protect the covering, and to keep well clear of rooflights and fragile sheeting.
How the survey changes by roof type
Single-ply membranes
Single-ply relies on its welded laps staying sound. Seams, corners and the details around outlets and upstands get a close look.
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.
What affects the cost of flat roof surveys
Several things affect the price of a survey:
- Whether it’s a home or a commercial building
- Whether you choose the Basic, Standard or Premium Survey
- The number of roofs, including extensions and garages
- Roof area
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. The price is always agreed first.
