Flat roof surveys for homes and businesses in Frogmore
Every flat roof covering tends to fail in its own way. Built-up felt tends to blister and crack, asphalt crazes and splits, EPDM can lift at its laps, and GRP can crack at board joints and edge trims. Single-ply PVC and TPO roofs are checked at their welds, edges and fixings. Once you know the covering and its condition, planning the next step is far easier. If you’re worried about pools of water lying on the roof and blisters and bubbles in the covering, we can find out what’s behind it.
Flat roofs on exposed homes in small places like Frogmore take more wind and rain, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, normally show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
After the visit, you get a written report with photographs, sent by email. It explains the condition of the flat roof, the defects we found and what we recommend.

What we look for on each type of roof
Mastic asphalt
Without seams, asphalt tends to fail through cracking and at its skirtings. Our report notes crazing, cracks and any likely entry points.
GRP fibreglass
GRP roofs can last up to about 30 years when they’re laid well. Cracking where boards meet or where the deck moves is a common early sign of trouble.

What else we do in Frogmore
Do you need a flat roof survey in Frogmore?
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. If they were rushed when the roof was laid, they’re frequently the first things to fail.
Problems we come across often include:
- Upstands pulling away from walls
- Failed seals around rooflight kerbs
- Signs of deflection in the roof deck
- Blistering in felt or asphalt
If your house is among the older ones in the streets near Church of the Holy Trinity, the flat roofs on later extensions tend to wear out long before the main roof.
Choosing a roof surveyor
- Which parts of the roof they’ll actually see
- What exactly goes into their report
- Whether the loft space is looked at, where there is one
- Whether they hold professional indemnity and public liability insurance
What you can safely check yourself
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
Frogmore questions
Do you carry out roof surveys in Frogmore?
Yes, Frogmore is within the area we cover. We work right across London and the South East. You can call 07833 053749 or email us with the address and some details, and we will talk through which survey suits.
How do I find out if my home in Frogmore is listed?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
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 complements a RICS home survey rather than replacing it, and structural calculations need a structural engineer.
How soon will I get the report?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline when booking.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We are a CAA-registered drone operator.
Does the survey cover asbestos?
Our survey doesn’t include asbestos testing. Buildings built or refurbished before 2000 may contain asbestos, for instance in cement roof sheets. We note anything that could contain it, and a specialist asbestos surveyor should check it before it’s disturbed.
How long is the visit?
That depends on the size and shape of the roof, but most surveys take an hour or two for a house, and longer for a large or complex roof. The written report follows by email.
Useful tips for Frogmore property owners
These tips come from what we see on roofs every week:
- Keep records of when the roof was laid and what work has been done
- Plan a survey before the covering reaches the end of its usual life
- Check the outlets after the leaves fall
- Check from a window for ponding after heavy rain
You get the report by email and can pass it to a roofer, your solicitor, the seller or your managing agent. It is written in plain English, with a photo of each defect, so others can follow it without going up to look.
Have the roof surveyed every few years, and after any work that goes through it. You will spot changes early and have a record to look back on.
Flat roof surveys in Frogmore: local notes
Historic houses like High Elms Manor, about 2.8 miles south-west, show how far back building in the area around Frogmore goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For businesses in and around places such as The Maltings, outlets and upstands on commercial flat roofs are the places to check before trouble starts. If you look after a building such as Park Street Church of England Voluntary Aided Primary School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

What’s near Frogmore
Locally, jobs take us to homes and businesses close to The Old Red Lion pub and Marlborough Science Academy, among other places. Frogmore has its own railway station: How Wood station.

The survey, step by step
You do not need to do much on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll take it from there. A typical survey takes about 1–2 hours at a typical home, with bigger or more complicated roofs taking longer. Older roofs in small places like Frogmore can have low, tight loft spaces, so it helps to know whether there’s a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- You tell us about the roof, its covering if you know it, and any leaks.
- We view the roof from the ground, from windows and from the roof where it’s safe to do so.
- Every part of the roof we can see is looked at: covering, falls, upstands, outlets, trims and rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- You get a photo-illustrated written report and our recommendations.
Before the survey
- Buyers: confirm access with the estate agent or seller
- Mention any parking restrictions on your street
- Keep pets in another room

Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Tell us about it as you book and we will plan the visit with that in mind.
Letting agents can arrange access with tenants. Surveys run on weekdays, Saturdays and Sundays, which can make access easier.
