Signs you need a flat roof survey in Merrow
A flat roof lies open to sun, rain and frost, and water drains off it slowly. Over the years, coverings harden, crack and start to come away at the edges. People normally call us when a leak appears, before a purchase, or when the roof may be near the end of its life.
These are some of the problems a survey can pick up:
- Ponding water that does not drain away
- A sagging deck under the covering
- Failed upstands where the roof meets a wall
- Outlets that hold water back
Take a building like Bushy Hill Junior School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Flat roof survey in Merrow: what you get
A flat roof does not shed water the way a pitched roof does. Because rain sits on it for longer, a small split, an open seam or a blocked outlet matters more. We check the surface, the falls, the upstands and the edge trims, and we note any sign that the deck below has got wet. That way, defects are found before they reach the room below. Typical surveys look at splits and cracks in the covering and raised blisters across the surface, across EPDM rubber, upstands and outlets and mastic asphalt.
Flat roofs in smaller places like Merrow can be more exposed, particularly where nothing shelters them, where wind can catch loose edges and trims. Felt and bitumen also age in strong sun. The signs are splits, blisters and edges coming away. A flat roof that still holds water days after rain is also worth a closer look.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Should I look at the roof myself first?
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, which helps when we check the roof.
What we do, step by step
We do not take risks to get a closer look. Everything that can be seen safely is inspected, and anything we cannot see is noted in the report. Most visits take about one to two hours at a typical home; commercial roofs usually need 3–4 hours. A visit to a smaller place like Merrow is no different on the day: outside, inside and from any safe vantage point, in that order. It helps to show us anything you’ve already noticed.
- 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.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- You get a report setting out the condition and our recommendations, in order of urgency.
Preparing for the visit
- If you are buying, check with the agent that we can get in
- Leave a clear route to the loft
- Have any paperwork from past roof work to hand

What we cannot see
Before you book, it’s worth knowing what a survey won’t do:
- Whether the deck or joists are strong enough
- The condition of the deck or insulation hidden under the covering
- A promise that the roof will not leak in future
If you’re not sure which survey you need, phone 07833 053749 or drop us an email and we will give you a straight answer before booking. The full list of what we check.
Roof types and parts we check
- Felt flat roofs
- Mastic asphalt
- Upstands and outlets
- Single-ply membranes
- GRP fibreglass
- EPDM rubber
How the survey changes by roof type
GRP fibreglass
A well-laid GRP roof often lasts up to about 30 years. Hairline cracks over board joints are an early warning we look out for.
Mastic asphalt
With age, asphalt can harden and crack with movement. We note where this is happening and how widespread it looks.
What a flat roof survey looks like in Merrow
With Clandon Park about 0.9 miles east, Merrow sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For an older house near a landmark like Church of St John the Evangelist, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you let a flat or house near Clandon station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Merrow is about 2 miles east of Guildford, in Surrey. Merrow gets the same service as everywhere else we work: a close look at what can be seen safely, photographs and a clear written report. Our Surrey coverage includes Merrow.

Merrow questions
Do you carry out roof surveys in Merrow?
Yes. We work right across London and the South East, and Merrow is part of that. Just ring 07833 053749 or email us and let us know about the property.
Do you cover smaller places like Merrow?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Can you survey in bad weather?
Light rain does not usually stop a survey. Heavy rain or strong wind can ground a drone and make the roof unsafe, so we will agree a new date if the weather is not suitable.
Do you survey roofs on blocks of flats?
Yes. Shared roofs just need a little more planning. Tell us about it when you book and we’ll plan the survey around it.
How many surveys have you done?
More than 5,000 surveys over 20+ years, across London and South East England.
What types of flat roof do you survey?
Felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply membranes are all part of the work. The report names the covering and explains its condition.
How long does the survey take?
Most surveys take about 1–2 hours on an ordinary house, or half a day or so for a commercial building. The report follows by email.
How we price flat roof surveys
Prices vary from roof to roof, and it comes down to:
- The type of building, from a house to a block or an office
- The use of thermal imaging or a drone
- The shape of the roof and its details
- Whether you choose the Basic, Standard or Premium Survey
Every price we give includes VAT, and the written report is part of the package. Prices start from £150, including VAT. Size, height and access decide where your roof falls.
Helping us price your survey
When you call or email, these details help:
- Where any leaks, stains or damp patches show inside
- The style of property, from a terrace to a block
- The address and postcode of the property
- Access details, such as a loft hatch or a shared roof
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply call 07833 053749 or email us whenever suits you.
