Landlord and commercial surveys in Longfield
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps when budgeting.
We survey roofs for landlords and agents as well as householders. A written report with photographs gives you a clear record of the leaking roof.
Roof leak investigations for homes and businesses in Longfield
Roof leaks rarely show up where you’d expect. It can run along a rafter, a batten or the underlay before it drips, so a ceiling stain is rarely directly below the cause. We follow it back towards where it starts, one likely route at a time. Patching the spot above the stain often misses the real cause. Finding the route first lets the repair go where it’s needed. If you are worried about leaks that appear only in driving rain and condensation that looks like a leak, we can find out what’s behind it.
Somewhere as small as Longfield, older roofs have often been repaired many times. A new leak may be fresh damage or the latest sign of long-term wear, and the difference matters, especially to an insurer. We check what can safely be seen and set out what we find. Damp in old walls and timbers is slow to dry, so the sooner the cause is found the better.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Can I check my roof myself?
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight.
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.

Longfield: your questions answered
Is Longfield within the area you cover?
We do. Villages and rural addresses get the same survey as a town house.
Is my home in Longfield listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it’s worth checking before planning any.
How do I book a survey in Longfield?
It’s easiest to ring 07833 053749 or send us an email. Give us the address and a few details about the roof, and we’ll point you to the right survey. We survey on weekdays, Saturdays and Sundays.
Do I need to be at home?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access; we’ll agree the details when you book.
Does the investigation include the repair?
A leak investigation finds and reports the likely source. The repair itself is a separate job. You get a report with photos showing where the water is getting in and what needs attention, which whoever carries out the work can follow.
Can you find a leak when it isn’t raining?
Often, yes. Stains, tide marks, damp timbers and moisture readings normally point the way. Intermittent leaks can be harder, so your photos and notes from wet days are very useful.
Can thermal imaging help find my roof leak?
Thermal imaging is used where it’s useful, and it is part of the Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
Practical tips
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Protect furniture and flooring under the leak
- Do not touch fittings that water is reaching
- Stay off ladders and the roof
- Mention any plumbing above the damp area
Standard includes a follow-up consultation to talk the findings through, while Premium includes one in person. You can ask us about anything that isn’t clear.
After a downpour, look in the roof space with a torch, keeping to boarded areas. Watch for water marks, wet underlay and damp wood. Take photos of anything that changes.
Leave it or get it looked at?
Water damage grows the longer it’s left. Damp spreads into rafters, ceilings and insulation. Tracing it now means less to put right later. Around Longfield, older homes frequently have old roof timbers, where water from a failed roof can cause rot if it is left.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.

Do you need a roof leak investigation in Longfield?
A roof valley collects the rain from two slopes. Split linings, slipped valley tiles or debris can push water under the slates or tiles. Leaks from valleys often show up some distance away inside.
People normally book a survey when they’ve noticed one of these:
- Water coming in around a roof light or dormer
- Drips from nail tips in a cold loft
- Damp ceilings under a flat roof
- Brown rings on upstairs ceilings
For site and facilities teams at buildings such as Longfield Academy, tracing a leak on a big roof starts with where the water appears and works back.

- What follow-up you get after the report
- Which viewpoints they use to see the roof
What we do, step by step
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. It usually takes between one and two hours on an ordinary house, and more on a big or complicated roof. In a small place like Longfield, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- You let us know where the water shows and when it appears.
- Inside, we check the damp area and the roof space above it.
- We check the likely entry points outside, like flashings, valleys, chimneys and gutters.
- Moisture readings and thermal imaging are used where they help.
- You receive a written report with photos showing the likely source and what needs attention.
Before we arrive
- Mention any parking restrictions on your street
- Move anything stored under the loft hatch
- Point out any leaks or damp patches
Booking a survey
A quick phone call is normally the easiest start: call 07833 053749 or drop us an email and we will ask a few questions about the roof. You’ll have a price before anything is arranged.

Wind, rain and roofs in Longfield
Cobham College, about 4 miles east, is one of the historic houses in the wider area around Longfield. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material. Many older homes in Kent have handmade clay tiles, including Kent peg tiles held by pegs through two holes, and tile-hanging on their upper walls. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Where water gets in depends a good deal on what the roof is made of and how it’s detailed.
If you live in an older home near Church of Saint Mary Magdalene, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks. If you run a business near Bluewater, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.
