Who it's for
- Homeowners who want to check a roof after a storm, trace a leak or damp patch, or find out whether a roof, chimney or gutter needs work before asking for quotes
- Landlords who want a record of the condition of their roofs
- Estate and letting agents acting for sellers and landlords
- Managing agents of blocks of flats who need to check flat roofs, parapets, communal gutters and chimneys
- Anyone planning roof work who wants a record of the roof before work starts
Why use a drone
Many roof defects cannot be seen well from the ground, and getting a person onto a roof usually means ladders, a platform or scaffolding. A drone can photograph roof slopes, chimney tops, valleys and gutters at close range, without anyone going onto the roof. It helps you find out whether a roof needs a roofer's attention, and shows the roofer where to look.
What we inspect
- pitched roofs: tiles and slates, ridges, hips, valleys and verges
- chimneys: stacks, pots, flaunching and flashings
- gutters, downpipe outlets, fascias and soffits
- flat roofs: coverings, edges, outlets and signs of standing water
- dormers, roof lights, parapets and upper walls that are hard to see from the ground
How we fly
DBISS is registered with the Civil Aviation Authority (CAA) as a drone operator. Every flight is planned in advance.
- Airspace. Most airports and airfields have a Flight Restriction Zone, where drones may fly only with permission, and flying is restricted around some other sites, such as prisons. We check your address against these areas before booking. Some addresses need permission from the airport or airfield first, and at some a flight is not possible. The CAA explains where drones can fly.
- Weather. We fly only when the wind, rain and visibility allow it safely. If the weather is unsuitable, we will agree another date with you.
- On the day. We check the site and the conditions again before take-off. The decision to fly is made on site.
What you get
Annotated images of the roof, chimneys and gutters, with the defects and areas of concern we found marked on them. You can share them with a roofer, your insurer or a managing agent.
The annotated images are typically sent within 5 working days of the inspection. Once they are sent, we offer you a call to talk them through.
What it does not cover
- going onto the roof, or lifting tiles, slates or other coverings
- anything under the roof coverings, such as the underlay, battens or roof deck
- testing whether the roof is watertight. The source of a leak is not always visible from the air
- the inside of the roof space, unless the drone inspection is part of a survey
- a specification or quotation for repairs. For costs, ask a roofer for a quotation
- a guarantee that we can fly. We fly only where airspace rules and the weather allow
Prices
A standalone drone roof inspection costs from £225, including VAT. We confirm the fee before you book. A travel supplement applies beyond about 25 miles of Hemel Hempstead. If you are buying the property, our Level 3 survey includes a drone roof inspection where flight is permitted.
