Why it’s worth a survey now in Queensbury

Caught early, a split or open seam in a flat roof is frequently a small repair. Leave it, and water can get into the insulation and deck, which can turn a patch into a replacement. Surveying it now tells you where you stand. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That’s a good reason to find problems early, while there is time to plan.

Flat roof survey starts from £150, including VAT. The final price depends on the size and height of the roof, access and the package you choose.

Why us?

  • An independent look at the roof
  • Plain-English reports with photos
  • Thermal imaging and drones used where they help
  • CAA-registered drone operator (Flyer ID and Operator ID)

Flat roof surveys for homes and businesses in Queensbury

If the house you are buying has a flat roof on an extension, dormer or garage, it’s worth knowing its condition before exchange. Felt roofs often last around 15 to 20 years, while EPDM and GRP often last longer. Our report records the covering, how it’s holding up and any defects we can see, with a photo of every defect. That gives you facts to raise with the seller or agent. We survey mastic asphalt, upstands and outlets and EPDM rubber, and people most frequently book us about raised blisters across the surface and blocked or damaged outlets.

London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, and each fails in its own way. Which one is on a roof in Queensbury shapes how it’s checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.

What you get is a clear record of the flat roof on the day we saw it. That makes it useful now and a handy reference later, such as when you want to compare after future work.

How it works

Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, take photos as we go and make notes for the report. It typically takes between one and two hours for a house, with bigger or more complicated roofs taking longer. In Queensbury, as in much of London, plenty of properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. If the building has a managing agent or access rules, let us know as you book.

  1. First we go through the roof, what’s beneath it and any problems so far.
  2. We look at the roof from the ground, windows and the roof where it’s safe.
  3. The covering is checked for wear, splits, blisters and standing water.
  4. Upstands, outlets, edge trims and rooflights are checked and photographed.
  5. The report, with photos and recommendations, comes to you by email.

Before the survey

  • Point out any leaks or damp patches
  • Check pets are kept safely away
  • Buyers: confirm access with the estate agent or seller

Advice

What this survey cannot tell you

It’s a careful look at the flat roof, not the whole story. The main limits are:

  • Parts of the roof that are not safe to walk on or view
  • The condition of the deck or insulation hidden under the covering
  • Whether the deck or joists are strong enough

Not sure which survey suits your roof? You can ring 07833 053749 or drop us an email and we will tell you. The full list of what we check.

What this survey covers

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

Rented homes, blocks and businesses

An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. We agree a time with the tenant beforehand.

For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.

Flat roofs in Queensbury

Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. With Headstone Manor about 2.7 miles west, Queensbury sits in an area with a long building history. If yours is one of the older homes, 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.

If you let a flat or house near Kenton station, the flat roof over a let home is worth a look before it becomes a tenant complaint. The streets around a church like All Saints Church are often among the oldest in a place, and if you own one of the older houses nearby, the joins between later flat roofs and the old walls are where problems normally start.

Common roof problems in Queensbury

Flat roofs often get walked on for other jobs: cleaning windows, fitting aerials or air conditioning, or clearing gutters. A covering that wasn’t designed for foot traffic can crack or puncture. Fixings added through the covering frequently start leaks too.

We are often asked to look at:

  • Upstands pulling away from walls
  • Cracked or split membrane
  • Blisters and bubbles in the covering
  • Failed seals around rooflight kerbs

Anyone responsible for a site like Glebe Primary School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.

What a roof survey includes

Questions from Queensbury

Do you carry out roof surveys in Queensbury?

Yes, Queensbury is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.

Can parking be tricky for a visit in Queensbury?

London parking needs a little planning, so let us know about permits, bays or a driveway when booking. The visit is then planned around what’s available.

Will this cover the whole house?

No. Our survey covers the flat roof only. It is not a RICS Level 2 or 3 home survey or a structural engineer’s report. Many buyers use it alongside a building survey.

How long will you be at the property?

Time on site depends on the roof; most visits take about 1–2 hours for a small flat roof at home, and longer for a large commercial one. The report is sent afterwards by email.

Can you test old roof sheets for asbestos?

Our survey does not include asbestos testing. Buildings built or refurbished before 2000 may contain asbestos, for instance in cement roof sheets. Anything that might contain it is flagged, so a specialist asbestos surveyor can check before work starts.

What does the report include?

A written report with photographs, explaining the condition of the flat roof, any defects and our recommendations, in order of urgency where relevant. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where it applies and structural analysis.

Can you find where water is getting through my flat roof?

We check the whole roof, since water can travel before it shows inside. Every split, lap, upstand, outlet and rooflight we can see is looked at. If the cause can’t be seen, we will say so and suggest what would help.

Before and after the survey

A little preparation and a few simple habits help. Our tips:

  • Keep clear of rooflights and fragile roof sheets
  • Ask contractors to protect the roof if they work on it
  • Keep outlets clear of leaves and moss
  • Check that new brackets or units haven’t damaged the covering

Once we’ve been, the findings are written up with photos. It explains the covering, its condition and every defect, and what we recommend. Turnaround is within 48 hours for a Basic Survey, 24 to 48 hours for a Standard Survey and the same day for a Premium Survey.

Keep outlets, gutters and hoppers clear, particularly after the leaves fall. Water that can drain away does far less harm than water that sits.
