Independent flat roof surveys in Patchetts Green

What we can’t see

Some things cannot be seen without opening up the roof, and that sets some limits:

  • Whether old sheeting or boards contain asbestos
  • The condition of the deck or insulation hidden under the covering
  • Areas we cannot see or reach safely, including fragile rooflights and sheeting

If you’re not sure which survey you need, phone 07833 053749 or send us an email and we will give you a straight answer. The full list of what we check.

What we check

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

Flat roof survey in Patchetts Green: what you get

A flat roof does not shed water the way a pitched roof does. Because rain sits on it for longer, a small split, an open seam or a blocked outlet matters more. The surface, the falls, the upstands and the trims are all looked at closely, and we look for signs that water has reached the deck. The aim is to find problems before they show up as a stain on a ceiling. We survey mastic asphalt, felt flat roofs and single-ply membranes, and the problems we are asked to look at most are edge trims that have lifted or split and blocked or damaged outlets.

Some older homes in villages like Patchetts Green are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.

Findings are set out part by part, from the coverings down to the gutters, with a note and a photo for each point. You will see the good as well as the bad.

For landlords and managing agents

Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photos included.

If the property is let, the agent or a tenant can let us in, at a time agreed ahead of time. We survey on any day of the week, which can make access easier.

What we do, step by step

We look at the roof from outside and, where it’s relevant and there’s safe access, from inside the roof space too. In the loft, the signs we look for are staining, damp, daylight and sagging. All in, the survey normally takes between one and two hours at a typical home, with bigger or more complicated roofs taking longer. Cottages and farmhouses around Patchetts Green frequently have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen.

  1. You send us the address and, for commercial roofs, an idea of the roof’s size.
  2. Inside, we look for signs of water under the roof where we can reach.
  3. The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
  4. We record every defect with a photo and its likely cause.
  5. You get a report setting out the condition and our recommendations, in order of urgency.

Before we arrive

  • Keep pets inside or away from the areas we’re looking at
  • For flats, make sure roof access has been agreed
  • Mention any parking restrictions on your street

Arrange a survey

A quick phone call is typically the easiest start: ring 07833 053749 or email us and we’ll ask a few questions about the roof. You’ll have a price before anything is arranged.

What a survey costs

When we price a survey, we consider:

  • The shape of the roof and its details
  • How many separate roofs there are, such as extensions, dormers and garages
  • Height and safe access
  • The type of building, from a house to a block or an office

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.

Getting in touch

There is no need for technical words. It’s enough to tell us:

  • What’s prompted the survey
  • Photos of the roof, taken safely from ground level or a window
  • Anything about access we should know
  • The style of property, from a terrace to a block

We survey roofs seven days a week. To arrange a day that suits you, ring 07833 053749 or email us with the address and the days you’d prefer.

Flat and commercial roofs around Patchetts Green

Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. About 3 miles north-west lies High Elms Manor, a reminder of how long the area around Patchetts Green has been built on. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.

Take an older house close to Church of St John the Baptist: the joins between later flat roofs and the old walls are where problems typically start. If you look after a building such as Queens' School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you look after a shop, office or commercial unit, for example near Harlequin Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

What happens if roof problems are left?

A survey can show whether a whole new roof is needed or whether the problems are in a few places. Sometimes a few details are to blame, and sometimes the covering has simply had its day. Our report gives you the evidence to discuss with a roofer. Older cottages and farmhouses around Patchetts Green can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.

There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, all inc. VAT. What your roof costs depends on its size, access and what you want to find out.

What you get with us

  • More than 20 years surveying roofs
  • An independent look at the roof

Your questions about flat roof surveys in Patchetts Green

Do you cover Patchetts Green?

Yes. We survey roofs across London and South East England, and Patchetts Green is part of that. Just phone 07833 053749 or send us an email and tell us about the property.

Is Patchetts Green within the area you cover?

Yes, we do. We cover the whole of London and South East England, and smaller places are part of that. The journey is planned ahead, so it is useful to know about access.

Will you walk on the flat roof?

We inspect from wherever is safe: on the roof where it’s safe, and from windows, nearby vantage points and inside. We never walk on fragile rooflights or sheeting.

Do you check flat roofs for asbestos?

Asbestos testing isn’t part of our survey. If we see materials that could contain it, like cement sheets on a building from before 2000, we flag them and recommend a specialist asbestos surveyor.

Does the report include photos?

Yes, every report has them. Pictures sit next to the findings they show, which makes the report easy to follow.

Do I need to be at home?

If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when you book.

Do you use drones?

Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We are a CAA-registered drone operator.

DIY checks: what’s safe

Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.

What you can’t do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That part is for a survey, using safe viewpoints and a drone where applicable.
