About our flat roof survey in Furnace Green

Offices, shops, industrial units and blocks of flats frequently sit under large flat roofs. A survey of a roof this size picks out worn covering, standing water and outlets that need attention. We record the condition with photos so work can be planned and budgeted. Commercial roofs are quoted for their size and access, so please ring 07833 053749 or email us with the address and an idea of the roof’s size. We’re often asked to look into cracked or split membrane and loose or cracked edge trims, on GRP fibreglass, felt flat roofs and EPDM rubber.

Around a smaller place like Furnace Green, flat roofs normally cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. What it’s covered in, and how well it was laid, decides what it needs. From an upstairs window, look for standing water, splits and edges coming away.

Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Furnace Green: your questions answered

My home in Furnace Green has a flat-roofed garage or porch. Is it worth having that looked at?

It’s frequently worth it, as these roofs are easy to forget. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check before they’re disturbed.

Is Furnace Green within the area you cover?

Yes, Furnace Green is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.

How many surveys have you done?

More than 5,000 surveys over 20+ years.

Can you survey in bad weather?

It can, depending on the survey. Drones can’t fly safely in strong wind or a downpour, and thermal imaging works best after a sunny day, with a dry roof and little wind. We will rearrange with you if the weather isn’t right.

Will this cover the whole house?

No. Our survey covers the flat roof only. It is not a RICS Level 2 or 3 survey of the whole building, and it is not a structural engineer’s report. It often sits alongside a buyer’s building survey.

Do you cover flat roofs on blocks of flats?

Yes. Commercial and residential flat roofs are both covered. A commercial roof normally takes about 3 to 4 hours on site, longer if it is large or complex, and larger roofs are quoted for their size.

Do you need to get into the loft?

If it is needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging.

Local flat roofs in Furnace Green

The wider area around Furnace Green has a long history of building, with Tyes Place about 4.3 miles south. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first. Many older homes in Sussex have handmade clay tiles and tile-hung walls. A few old Sussex buildings still carry heavy Horsham stone slabs. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.

If you run a business near County Mall, outlets and upstands on commercial flat roofs are the places to check before trouble starts. Take an older house close to St Andrew's Church: the flat roofs on later extensions tend to wear out long before the main roof.

Honest limits

Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:

  • Parts of the roof that are not safe to walk on or view
  • Whether the deck or joists are strong enough
  • Whether old sheeting or boards contain asbestos

If in doubt, phone 07833 053749 or email us and we will suggest the right survey before you book. The full list of what we check.

Roof types and parts we check

  • EPDM rubber
  • Mastic asphalt
  • Single-ply membranes
  • Upstands and outlets
  • GRP fibreglass
  • Felt flat roofs

What we are asked to look at in Furnace Green

A flat roof lies open to sun, rain and frost, and water drains off it slowly. Over the years, coverings harden, crack and start to come away at the edges. Most people book a survey after a leak, before buying, or when they think the roof is getting old.

A survey can pick up problems like:

  • Signs of deflection in the roof deck
  • Damaged trims at the roof edge
  • Leaks around rooflights
  • Outlets that hold water back

Landlords with a home close to Three Bridges station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

Choosing a roof surveyor

  • Whether the inside of the roof is included
  • What they will not be able to tell you
  • If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
  • Will the report include photos?

What a good roof survey covers

Surveys for landlords and agents in Furnace Green

Letting agents often book on a landlord’s behalf, and the report can go to both. Access is agreed with the tenant beforehand.

We survey roofs for letting agents and landlords as well as homeowners. The report gives you a dated record of the flat roof, with photos, useful for planning maintenance.

What we do, step by step

We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the roof space where it can be reached. All told, expect roughly 1–2 hours for a house, and more on a big or complicated roof. Parking around Furnace Green is typically easier than in a town centre, but mention lanes, gates or long drives. On bungalows and lower roofs, much can be seen from ground level, with the loft showing the underside.

  1. You tell us about the roof, its covering if you know it, and any leaks.
  2. The roof is inspected from safe viewpoints, and from the roof itself where that’s safe.
  3. The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
  4. We check the rooms or spaces under the roof for staining where we can reach them.
  5. The findings are written up with photos and recommendations and emailed to you.

How to prepare

  • Check pets are kept safely away
  • Find any records of previous roof work
  • Point out any leaks or damp patches

What a survey costs

To price your survey, we check:

  • Basic, Standard or Premium
  • The use of thermal imaging or a drone
  • The number of roofs, including extensions and garages
  • Commercial roofs and larger buildings

One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. The roof’s size, height and access matter as well.

Booking your survey

We’ll usually ask about:

  • The reason for the survey, such as buying, a leak or storm damage
  • Pictures from the garden or a window, if you have them
  • What kind of property and roof it is
  • Access details, such as a loft hatch or a shared roof

Our phone lines are open seven days a week, including Saturdays and Sundays. For a price or to book, call 07833 053749 or send us an email.

Practical tips

Small things make a difference. Our tips:

  • Never stand on rooflights or fragile sheeting
  • Limit foot traffic on the covering
  • Look for standing water a day after rain
  • Note the date and type of any roof work

Buyers can take the findings back to the seller or the agent. It can support a request for work before completion or a conversation about price, depending on the findings.

Book a survey every few years, and again after new fixings, units or rooflights go in. You’ll spot changes early and have a record to look back on.
