Flat Roof Survey in Warner's End
Flat roof surveys across Warner's End, with over 20 years’ experience behind it. Every survey ends with a written report and photographs.
- Blistering in felt or asphalt
- Pools of water lying on the roof
- Dips that suggest the deck is deflecting
What happens on the day
Once we’ve finished looking, we write up our findings as a report with photos. As for time on site, most surveys take about one to two hours for a small flat roof at home, and longer for a large commercial one. Homes around Warner's End often have gardens on more than one side, which gives us room to step back and see the roof. Mention any side of the property we can’t get to. The loft, where there’s safe access, completes the picture.
- We agree the roof to be surveyed, its use and any leaks you know about.
- The roof is viewed from safe positions, including the roof itself where that’s safe.
- We check the covering for splits, blisters, ponding and wear.
- We photograph and record the outlets, upstands, trims and rooflights.
- The report, with photographs and recommendations, comes to you by email.
Before we arrive
- Show us where any leaks or stains appear
- Dig out any old roof reports or invoices
- For a flat or shared roof, check access with the freeholder or managing agent

Flat roof survey in Warner's End
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. On PVC and TPO single-ply roofs, we look closely at the welded laps, edges and fixings. Knowing what you have and how it’s doing helps you plan what comes next. We’re often asked to look into standing water left after rain and blocked or damaged outlets, across felt flat roofs, mastic asphalt and GRP fibreglass.
Around a smaller place like Warner's End, flat roofs normally cover extensions, garages and dormers. Even a small flat roof can let plenty of water into the room below. Knowing the covering and how it was laid tells you what to expect from it, from felt and asphalt to EPDM rubber and GRP. From an upstairs window, look for standing water, splits and edges coming away.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Landlord and commercial surveys in Warner's End
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Larger roofs take longer, so they’re priced to suit.
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
What a flat roof survey doesn’t cover
This isn’t a RICS building survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- Fragile surfaces, which we do not walk on
- Whether the deck or joists are strong enough
- What’s under the membrane without opening it up

Flat and commercial roofs around Warner's End
If your home is older, it is worth knowing whether it is listed or in a conservation area before planning roof work. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you look after a building like Micklem Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you own a rental within reach of Hemel Hempstead station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. For an older house near a landmark such as St Alban's Church, flat-roofed rear additions and dormers added over the years are worth checking.

DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we check the roof.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
Tips that help
Over many surveys, some simple habits stand out:
- Note the date and type of any roof work
- Limit foot traffic on the covering
- Check that new brackets or units haven’t damaged the covering
- Book a survey every few years
You can use the report to ask roofers to quote for the same work. Because everyone is pricing the same findings, the quotes are easier to compare. You stay in control of who does the work and when.
After heavy rain, look at the roof from an upstairs window if you can. If water is still there a day or two later, have it checked.
How we price flat roof surveys
Prices always include VAT. The things that change the price are:

Our price is from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, with VAT included, and we can help you choose.
Getting in touch
We will usually ask about:
- Any deadline, such as an exchange date
- Photos of the roof, taken safely from ground level or a window
- What’s prompted the survey
- Whether there’s a loft hatch, a shared roof or tricky access
Once you know what you need, ring 07833 053749 or send us an email. From there it is a case of choosing a package, agreeing the price and fixing a day, weekday or weekend.
FAQs for Warner's End
My home in Warner's End has a flat-roofed garage or porch. Is it worth having that looked at?
Frequently, yes, so mention it when booking. Many homes in new towns like Hemel Hempstead have flat-roofed garages and porches, and felt roofs often last around 15–20 years.
Is Warner's End within the area you cover?
Yes, we do. We work right across London and the South East, and smaller places are part of that. Longer journeys are simply planned ahead of time.
Will this cover the whole house?
No. It is a closer look at the flat roof, not a survey of the whole property. It works alongside a RICS home survey, not instead of one, and it isn’t a structural engineer’s report.
What insurance do you have?
We hold professional indemnity and public liability insurance.
Does the report include photos?
Yes. Photos are taken throughout the survey, and the report uses them to show each finding.
Does the survey cover asbestos?
Asbestos testing isn’t part of our survey. Where a roof has materials that might contain asbestos, such as old cement sheeting, the report flags them so a specialist asbestos surveyor can check them.
Should I worry about standing water on my flat roof?
Water that lies on a flat roof for days is a sign that something needs attention. It could be the outlets, the falls or a deflecting deck. We check each of these and record what we find.
