Flat roof survey in Dedworth: what you get
Buying a home with a flat-roofed extension, dormer or garage? It’s useful 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. Our report records the covering, how it is holding up and any defects we can see, with photographs of each. You then have something specific to put to the seller or agent. If you’ve noticed splits and cracks in the covering and upstands pulling away from walls, we can find out what’s behind it, whatever the roof.
Flat roofs in smaller places like Dedworth can be more exposed, especially where nothing shelters them, so wind catches loose edges and trims. Sun on a flat roof also ages felt and bitumen. Splits, blisters and lifting edges are what to look out for, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
We write the report in plain English, so you do not need to be a roofer to follow it. Photos show what each point refers to.

Tips from our surveys
Getting the most from a flat roof survey starts before we arrive and carries on afterwards. Tips:
- Limit foot traffic on the covering
- Note any new marks on ceilings beneath the roof
- Note the date and type of any roof work
- Treat rooflights and old sheeting as fragile
Questions about the findings are always welcome. Standard Surveys come with a follow-up consultation, and Premium Surveys with an in-person one, giving you a chance to go through what we found.
Check the roof from a window after a downpour. Water still lying a day or two later is worth getting looked at.
How the survey changes by roof type
GRP fibreglass
GRP roofs can last up to about 30 years when they’re laid well. Hairline cracks over board joints are an early warning we look out for.
Rooflights and upstands
The joins around rooflights and at upstands are common leak points. We check the seals and the covering around each one.

Landlords, agents and block managers in Dedworth
Businesses and commercial landlords can book us too. Larger roofs take longer, so they’re priced to suit.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out in order of urgency where relevant.
DIY checks: what’s safe
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Flat and commercial roofs around Dedworth
St Leonard's Hill, about 0.6 miles south, is one of the historic houses in the wider area around Dedworth. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first. Within a mile and a half or so of Dedworth there are several hotels. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
For site and facilities teams at buildings such as Dedworth Green First School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. If you let a flat or house near Windsor & Eton Central station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For hotels and guest houses around Dedworth, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do.

The survey, step by step
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it’s applicable and the weather allows. A typical visit takes about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. With a bit of garden around a house, as there often is around Dedworth, the roof can be viewed from several angles. Mention any side of the property we cannot get to. Inside, the loft is checked where it can be reached safely.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- The roof is inspected from safe viewpoints, and from the roof itself where that is safe.
- The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
- We check the rooms or spaces under the roof for staining where we can reach them.
- We send a written report with photos, the defects we found and what we recommend.
How to prepare
- Buyers: confirm access with the estate agent or seller
- Move anything stored under the loft hatch
- Keep pets out of the way during the survey
