Flat roof survey in South Merstham, Surrey
We carry out flat roof surveys in South Merstham and the rest of Surrey. We survey on any day of the week.
- Pools of water lying on the roof
- Damaged trims at the roof edge
- Blocked or damaged outlets
What we look for on each type of roof
Single-ply membranes
Single-ply membranes can be damaged by foot traffic and equipment on the roof. We note any punctures, tears and loose areas we can see.
Mastic asphalt
With age, asphalt can harden and crack with movement. The report shows where it is cracking and how far it seems to extend.
Flat roof surveys for homes and businesses in South Merstham
A flat roof survey looks at the covering, the edges, the outlets and the details where the roof meets walls 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. You get a written report with photos and our recommendations. We survey mastic asphalt, EPDM rubber and felt flat roofs, and people most frequently book us about upstands pulling away from walls and leaks around rooflights.
In smaller places like South Merstham, 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. What it’s covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. From an upstairs window, look for standing water, splits and edges coming away.
If any part of the flat roof couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t.

Do you need a flat roof survey in South Merstham?
Flat roofs swing between hot and cold more than most parts of a building. That movement pulls at seams, laps and the joints between boards, which can open splits and cracks over the years. Coverings that have hardened with age tend to suffer most.
It’s worth booking a survey if you’ve seen:
- Blocked or damaged outlets
- A sagging deck under the covering
- Cracked or split membrane
- Standing water left after rain
If you look after a shop, office or commercial unit, for example near The Belfry, the flat roofs over shops and commercial units are worth checking before a leak, not after.
Before booking anyone
- When you’ll get the report
- Their insurance cover
- How long they’ve been surveying roofs
- Will they check the loft as well as the outside?
What we do, step by step
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. Most visits take about one to two hours at a typical home, though large, tall or awkward roofs take more time. Some parts of a survey depend on the weather, so a visit to South Merstham is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- We start with the address and, on larger roofs, the roof area and access.
- Inside, we look for signs of water under the roof where we can reach.
- We view the roof from safe positions and never walk on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
Getting ready for the survey
- If you are buying, check with the agent that we can get in
- Jot down any questions you want answered
- Agree roof access with the managing agent if it’s shared
Getting a price
If you are buying, it is useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just phone 07833 053749 or drop us an email when you are ready.

What affects the price in South Merstham
Not every roof costs the same to survey, and it comes down to:
- The package you choose: Basic, Standard or Premium
- The shape of the roof and its details
- Extensions, dormers and garages with roofs of their own
- Any need for thermal images or a drone flight
Our price is from £150, including VAT. The final price depends on the size and height of the roof, access and which survey you book.
What we need to know
These details help when you contact us:
- Where the property is, with the postcode
- Whether there is a loft hatch, a shared roof or tricky access
- Why you want a survey: buying, a leak, a storm or new work
- Any photos you have, taken from ground level or a window
Most bookings start with a short call: ring 07833 053749 or send us an email and we will ask a few questions about the roof. The price is agreed before a date is set.
Useful tips for South Merstham property owners
A survey works best with a little help from you, before and after. Tips:
- Ask whoever fits equipment on the roof to make good the covering
- Never stand on rooflights or fragile sheeting
- Watch the ceilings below the flat roof for stains
- Look for standing water a day after rain
The report is emailed to you, ready to share with a roofer, the seller or a managing agent. Each defect is described in plain words and shown in a photo, so anyone reading it can see what we saw.
Book a survey every few years, and again after new fixings, units or rooflights go in. You will spot changes early and have a record to look back on.
South Merstham: your questions answered
Do you cover South Merstham?
Yes, South Merstham is one of the places we work. The survey and report are the same in South Merstham as anywhere else.
How do I find out if my home in South Merstham is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you go up onto the roof?
It depends on what’s safe: on the roof where it is safe, and from windows, nearby vantage points and inside. We never walk on fragile rooflights or sheeting.
How long is the visit?
It usually takes between one and two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. The report follows by email.
Can you inspect my roof with a drone?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
Are you structural engineers?
No. We point out what can be seen, such as sagging or deflection, but we’re not structural engineers and do not carry out calculations. If we think you need an engineer, the report says so.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Flat roof surveys around South Merstham
There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so check with the council. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
If you own a rental within reach of Merstham station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Take a building like Merstham Primary School: schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

Why it is worth a survey now in South Merstham
Waiting for a stain inside means the water has already got through the layers. A survey can find worn areas and failing details before that point, so you can plan the work rather than react to it. Tradespeople may need to travel further to a smaller place like South Merstham, so it helps to plan roof work rather than call someone out in a hurry. A survey gives you that notice.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. The price is always agreed first.
