Flat roof survey in Knapp, Hampshire
Flat roof surveys around Knapp, with findings in writing and pictures to back them up. Weekday and weekend visits available.
- Failed upstands where the roof meets a wall
- Raised blisters across the surface
- Water getting in at rooflights
The survey, step by step
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit usually takes roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Older roofs in small places like Knapp can have low, tight loft spaces, so tell us about the loft hatch and any ladder. We only go where it’s safe.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- We check the roof from wherever it can safely be seen.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- Where there’s safe access, we check the ceilings and spaces below for signs of water.
- We send a written report with photos, the defects we found and what we recommend.
Preparing for the visit
- If it isn’t your property yet, arrange access through the agent
- Let us know about parking near the property
- Show us where any leaks or stains appear

How a flat roof survey works in Knapp
Each type of flat roof has its own weak points. 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. Common reasons to book are blocked or damaged outlets and failed seals around rooflight kerbs, on mastic asphalt, single-ply membranes and upstands and outlets.
Somewhere as small as Knapp, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access beforehand. If there are outbuildings or garages with flat roofs, mention them when you book.
Most points in the report come with a picture, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Flat and commercial roofs around Knapp
Before planning roof work on an older home, find out whether it’s listed or in a conservation area. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area. A number of Hampshire villages keep thatched roofs on their older buildings. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Anyone responsible for a site like Ampfield Church of England Primary School will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Take an older house close to Church of St Mark: flat-roofed rear additions and dormers added over the years are worth checking. For landlords with property near Chandlers Ford station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

How the survey changes by roof type
GRP fibreglass
GRP can crack if the deck beneath flexes or if the resin was laid too thin. We record any cracking and any signs of the deck moving.
EPDM rubber
Lifting at the edges and loose areas of membrane are common EPDM problems. We record any we can see, with photographs.
Should I look at the roof myself first?
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
Questions from Knapp
Do you cover Knapp?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Does a conservation area affect roof work in Knapp?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day. Just say which days work for you.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. 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.
Can you survey a flat roof on an office or unit?
Yes. Offices, units, shops and blocks of flats are all part of our work. We quote bigger roofs on their size and how they’re reached, so call 07833 053749 or drop us an email with the address.
How many surveys have you done?
We have completed more than 5,000 surveys, across 20+ years of surveying roofs.
Practical tips
There is plenty you can do without going near the roof. Here’s what helps most:
- Clear roof outlets and gutters each autumn
- Have the roof looked at again after a severe storm
- File the paperwork for the roof and any repairs
- Never stand on rooflights or fragile sheeting
If you’re buying, the report gives you something specific to take back to the seller or agent. It can support a request for work before completion or a conversation about 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.
