Flat Roof Survey in Inner Avenue
We carry out flat roof surveys in Inner Avenue and the rest of Southampton. We survey seven days a week.
- Leaks around rooflights
- Loose or cracked edge trims
- Outlets that hold water back
How it works
There isn’t much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. The survey itself takes roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. With a bit of garden around a house, as there often is around Inner Avenue, the roof can be viewed from several angles. Let us know if any side is fenced off or hard to reach. Inside, the loft is checked where it can be reached safely.
- First we go through the roof, what’s beneath it and any problems so far.
- We check the roof from ground level, windows and the roof where it’s safe.
- We check the covering for splits, blisters, ponding and wear.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- A written report with photos and recommendations is emailed to you.
Before the survey
- Find any records of previous roof work
- Have keys ready for side gates, garages or roof access doors
- If you are buying, let the agent know when we are coming

Advice
About our flat roof survey in Inner Avenue
A flat roof survey looks at the covering, the edges, the outlets and the details where the roof meets walls and rooflights. We cover felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply roofs. It suits a small roof over an extension or garage as well as a large one over flats, offices or units. The findings go into a written report with photos, setting out the defects and what we’d recommend. We survey single-ply membranes, felt flat roofs and GRP fibreglass, and the problems we’re asked to look at most are water getting in at rooflights and damaged trims at the roof edge.
In a smaller place like Inner Avenue, some flat roofs sit in the open, so wind catches loose edges and trims. Felt and bitumen also age in strong sun. Splits, blisters and lifting edges are what to look out for. Standing water that lingers for days after rain is another sign worth watching for.
Where we cannot see part of the flat roof, the report says so. That way, it’s clear what was covered and what wasn’t.

How the survey changes by roof type
Felt and built-up roofs
A felt roof often lasts around 15 to 20 years, though quality and upkeep make a big difference. Our report sets out its condition and the areas most at risk.
GRP fibreglass
GRP roofs are laid as a resin and glass-fibre layer over boards. The survey checks for cracking at board joints, at the edge trims and where the roof meets walls.
Common roof problems in Inner Avenue
Flat roofs take the full force of the weather on a surface that drains slowly. In time, the covering dries out, cracks and loosens at its edges and laps. People normally call us when a leak appears, before a purchase, or when the roof may be near the end of its life.
Here are some of the things we see often:
- Gaps at upstands and abutments
- Splits and cracks in the covering
- Blocked or damaged outlets
- Standing water left after rain
For landlords with property near St Denys station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Questions to ask before booking
- Their track record with similar roofs
- Are they insured for the work?
- When you’ll get the report
- What the survey will not cover
What happens if roof problems are left?
Most flat roofs are out of sight, so they’re easy to forget. Many owners only find out a roof is worn out when water comes through. Regular surveys mean it will not come as a surprise. Tradespeople may need to travel further to a smaller place like Inner Avenue, so it helps to plan roof work rather than call someone out in a hurry. Knowing early gives you time to get the right people in.
Prices quoted always include VAT, and the written report is part of the package. Our price is from £150, including VAT. Size, height and access decide where your roof falls.

Tips that help
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Clear roof outlets and gutters each autumn
- Note the date and type of any roof work
- Plan a survey before the covering reaches the end of its usual life
- Check from a window for ponding after heavy rain
If you are buying, the report gives you something specific to take back to the seller or agent. You might ask for work to be done before completion, or discuss the price, depending on what we found.
After heavy rain, look at the roof from an upstairs window if you can. Water still lying a day or two later is worth getting looked at.
Your questions about flat roof surveys in Inner Avenue
Do roofs near the sea, like those around Inner Avenue, take more of a battering?
Generally, yes: wind and salt air take more of a toll near the sea. Exposed details like ridges, verges, flashings and metal fixings are the ones to watch, and Inner Avenue is within about 2 miles of the coast.
How do I find out if my home in Inner Avenue is listed?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
How do I book a survey in Inner Avenue?
Just phone 07833 053749 or email us. We’ll ask a few questions, confirm the price and agree a date.
Do I need to be at home?
That depends on the survey. For inside areas and the loft space, someone has to give us access, while outside access can be discussed when you book.
Do you look for flat roof leaks?
The survey covers the covering and all the details where leaks typically begin, recording anything that could let water through. Where the source is not obvious, a roof leak investigation or electronic leak detection may be the next step.
Will you check the loft?
Where it’s relevant to the survey and there’s safe access, yes. Please clear anything stored under the hatch.
Can you survey any kind of flat roof?
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.

What a flat roof survey looks like in Inner Avenue
Inner Avenue lies within about 2 miles of the sea, and places near the sea get more salt in the air and more wind than inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. About 1.2 miles south lies Southampton Tudor House and Garden, a reminder of how long the area around Inner Avenue has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
For hotels and guest houses around Inner Avenue, a roof problem found early is far less disruptive than one found by a guest, so it is worth knowing the roof’s condition. Anyone responsible for a site like Bevois Town Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
