Leave it or get it looked at?
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, while there is still time to plan the work. In an older home around How Wood, water from a roof defect can get into timber and plaster, and that is a much bigger job than the original defect.
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.

Flat roof survey in How Wood
Offices, shops, industrial units and blocks of flats frequently sit under large flat roofs. On a roof like this, a survey shows where the covering is wearing, where water is ponding and which outlets need attention. We record the condition with photos so work can be planned and budgeted. Commercial roofs are quoted for their size and access, so it helps if you ring 07833 053749 or email us with the address and a rough idea of the roof area. We survey felt flat roofs, GRP fibreglass and upstands and outlets, and the problems we’re asked to look at most are loose or cracked edge trims and failed seals around rooflight kerbs.
Flat roofs in smaller places like How Wood can be more exposed, particularly where nothing shelters them, where wind can catch 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.
How fast the report arrives depends on the package: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Practical tips
You don’t need to be a roofer to help. What helps most:
- Note where water lies after a downpour
- Ask whoever fits equipment on the roof to make good the covering
- Have the roof looked at again after a severe storm
- Check the outlets after the leaves fall
Many people send the report to two or three roofers for quotes. Because everyone is pricing the same findings, the quotes are easier to compare. You stay in control of who does the work and when.
Keep foot traffic on a flat roof to a minimum. Where someone does need access, ask them to use boards or a protected route, and remind them never to step on rooflights or fragile sheets.
When you need someone else
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- Whether old sheeting or boards contain asbestos
- Whether the deck or joists are strong enough
- Hidden layers beneath the covering

Landlords, agents and block managers in How Wood
Letting agents can arrange access with tenants. We survey seven days a week, which can make access easier.
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Larger roofs take longer, so they’re priced to suit.
What happens on the day
Every visit follows the same pattern: we hear what you’ve seen, inspect the roof from each safe vantage point, photograph what we find and record our findings for the written report. 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. In a smaller place like How Wood, parking is seldom the issue; lanes, gates and long drives are worth mentioning. Low roofs on bungalows can often be seen well from ground level, and the loft shows the rest, while taller roofs may need other vantage points or the drone where it applies.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- 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.
- We record every defect with a photo and its likely cause.
- The report explains the condition and recommends what to do first.
Before the survey
- If you’re buying, check with the agent that we can get in
- Leave side gates unlocked
- Jot down any questions you want answered

Advice
Questions from How Wood
Is How Wood within the area you cover?
We do. A small place gets exactly the same survey as a big one.
Do you cover How Wood?
We do. The survey and report are the same in How Wood as anywhere else.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. Roofs over flats are often shared, so the freeholder or managing agent needs to agree access. We inspect only the parts we are allowed to reach.
Will you walk on the flat roof?
Only where it’s safe to do so. Otherwise we use windows, vantage points and the spaces below, and we note any area we couldn’t see. We do not walk on fragile rooflights or sheeting.
Do I need to be at home?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in; we will agree the details as you book.
What does ponding on a flat roof mean?
Standing water on a flat roof deserves a closer look. It often means a blocked outlet, poor falls or a dipping deck, and it wears the covering faster. Our survey notes the ponding and what seems to be causing it.
How soon will I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. Mention any deadline when booking.

What else we do in How Wood
Do you need a flat roof survey in How Wood?
People go onto flat roofs for all sorts of reasons: cleaning windows, fitting aerials or air conditioning, or clearing gutters. A covering that wasn’t designed for foot traffic can crack or puncture. New brackets and fixings through the roof are another common source of leaks.
Things that often lead to a survey include:
- Failed seals around rooflight kerbs
- Pools of water lying on the roof
- Edge trims that have lifted or split
- Blocked or damaged outlets
If you look after a building such as How Wood Primary and Nursery School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
What to check before booking
- Do they have a CAA Flyer ID and Operator ID for drone work?
- How they plan to inspect the roof safely
- Whether the loft space is looked at, where there is one
- What follow-up you get after the report
