FAQs for Gossops Green
Should a flat-roofed garage or porch in Gossops Green be checked too?
Yes, if you’d like it included, mention it when you book. On buildings from before 2000, cement sheet roofs may contain asbestos and should be checked by a specialist asbestos surveyor before anyone disturbs them.
Does a conservation area affect roof work in Gossops Green?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
How fast do I get the report?
Report times are set by the package. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, tell us as you book.
What happens next?
You receive the written report by email, with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from the freeholder or managing agent. We inspect only the parts we are allowed to reach.
Do you take photos of the roof?
Yes. We photograph the roof as we go, and the report uses them to show each finding.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage methods are usually carried out on a wet roof, while high-voltage testing needs a dry, exposed membrane.
How electronic leak detection works in Gossops Green
ELD can be carried out in more than one way. Low-voltage testing is typically done with the surface wet and high-voltage methods need the membrane dry and exposed. Which one suits depends on the membrane and the layers of the roof, and we’ll explain our choice. If neither method suits your roof, we will tell you at the outset. Common reasons to book are new membranes needing a check before handover and breaches hidden under paving or planting, across single-ply roofs, commercial flat roofs and green roofs.
Around a smaller place like Gossops Green, flat roofs typically cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. What it is covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. Ponding, splits and lifting edges are the signs to look for from a window.
Findings are set out part by part, from the main slopes down to the gutters and outlets, with a note and a photo for each point. It records what’s sound as well as what is not.

What else we do in Gossops Green
Electronic leak detection in Gossops Green: local notes
Gossops Green is part of Crawley, one of the post-war new towns. Many homes in the new towns date from the post-war decades, with concrete interlocking tiles, low-pitched roofs and flat-roofed garages and porches. Flat-roofed garages, porches and extensions from that era may have been re-covered more than once, or not at all. England has around 10,000 conservation areas and about 500,000 listed buildings. If your home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission, so the council is the place to ask.
If you look after a shop, office or commercial unit, for example near County Mall, a flat roof over a business is out of sight and out of mind until it leaks. If you look after a building such as Ifield Community College, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. If you own a rental within reach of Ifield station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

How it works
Where it’s relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging. The whole visit normally takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. A visit to Gossops Green is planned like any other: the time, the access and where to park are agreed ahead of time. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.

What affects the price in Gossops Green
A few things affect what a survey costs:
- Height and safe access
- The use of thermal imaging or a drone
- The type of building, from a house to a block or an office
- Features like valleys, chimneys, dormers and parapets

- Any marks or damp showing indoors
- Your postcode, so we can check access and travel
- Pictures from the garden or a window, if you have them

Practical tips
A little preparation and a few simple habits help. Some pointers:
- Use boards when working on the roof
- Have roof specifications to hand
- Don’t keep patching the same spot
- Keep outlets clear of debris
If water has been getting in, insulation under the membrane may be wet. Your roofer can advise on that and other checks can help judge it.
Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.
What this survey cannot tell you
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- How wet the insulation is
- Leaks from walls, copings or rooflights
- Areas we cannot reach or that can’t be tested
If in doubt, phone 07833 053749 or use the contact form and we’ll recommend the right survey. What our survey covers.
What this survey covers
- Liquid-applied waterproofing
- Commercial flat roofs
- Green roofs
- Single-ply roofs
- Flat roof membranes
- Roof terraces and balconies
What you can safely check yourself
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
Different roofs, different checks
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.
Liquid-applied waterproofing
Liquid waterproofing has no laps, but can still have thin spots or holes. Suitability for ELD depends on the system.
