This article follows on from a previous article where we outlined how drones are useful for roof surveys In this article we explore what exactly roof inspections are and what they involve by answering the following questions: What is a roof inspection? When should you have a roof inspection? And why do we use drones for roof inspections? Keep reading to find out how roof inspections can help you to #ONEUPYOURBUSINESS!

WHAT IS A ROOF INSPECTION?

A roof inspection is having your roof professionally inspected to resolve any roofing issues or to spot any potential problems early on before the situation worsens and becomes an emergency.

There are two types of roof inspections:

  • Exterior inspection: this mainly involves checking the exterior of roofs by climbing up onto them or with the use of drones to check for leaks, the conditions of your soffits, tiles, shingles, and chimney, and for any structural damage or rotting, etc.
  • Interior inspection: an interior roof inspection involves checking the attic/loft for signs of rotting or mould, build-up of moisture and condensation, and checking ventilation and the installation

After inspections are carried out, you should be provided with a detailed guided report of what has been checked and what needs repairing so you get any issues resolved quickly and efficiently.

WHEN SHOULD YOU HAVE A ROOF INSPECTION?

We have identified that roof inspections are great for identifying problems such as water damage, shingle deterioration, damaged flashing, mould, and so on. However, if you were to try and conduct a roof inspection yourself, some problems may be missed as not all problems can be obvious to an untrained eye. Hiring professionals can help you to identify any hidden problems and suggest repairs. It is known that cold weather often causes the most damage to the exterior although, regardless of what the season is, roof inspections are crucial for early detection of potential problems. Therefore, below we have identified several reasons as to when you should consider getting a roof inspection:

  • There has been big weather events: Storms, heavy rain, high winds, snow, and hail can damage your roof; this may even result in insurance claims. Getting your roof inspected after big weather events can provide you with evidence for your insurance claims as well as identify problems, if any, to help you get maintenance and repairs right away and give instant attention to emergency fixes
  • You need evidence for your insurance provider: If your insurance provider is asking for evidence of your damages then getting a roof inspection can provide you with a detailed roof report to attach to your policy
  • You notice signs of aging: The roofing industry benchmark states that low-slope roofing has a life expectancy of around 20 years, and single-ply roofs are expected to last between 25 and 40 years. As your roof gets older, weathering and aging can cause problems to your roof and eventually your roof will need replacing, having roof inspections as your roof gets older can address problems that can arise preventing the need for an emergency roof replacement
  • You want to determine how energy-efficient your building is: Not only can roof inspections allow you to identify any problems you may have with your roof, but it can also help you to determine how energy efficient your building is to help you reduce your energy bills
  • Drains and gutters are obstructed: Roof inspections can identify blockages in your drains and gutters and pinpoint exactly where the build-up is to resolve the problem

Furthermore, not carrying out a roof inspection can allow problems to go unnoticed, reduce your roofs lifespan, and allow the problems to continue to develop into something more serious which can lead to costly repairs and health and safety issues.

WHY DO WE USE DRONES FOR ROOF INSPECTIONS?

We have already delved deeper into why we use drones for roof inspections in a previous article that covered how drones can dramatically improve your workflow. Below, we outline the top advantages mentioned:

  • Increases safety: Traditional roof inspections require cumbersome cherrypickers or highly polluting helicopters which can be dangerous and a nuisance to your neighbourhood. Using drones helps to minimise risks, as it allows us to work safely from the ground and eliminates the need of scaffolding. Drones also allow us to get to obstructed areas and fly further away from dangerous objects whilst still producing highly detailed and accurate results with close-up images of the roof
  • Saves time and money: Using drones produces comprehensive results quicker when compared to traditional methods. Drones eliminate all the guesswork as we can deliver you high-dynamic-range images and videos with enhanced detail and contrast across all areas of the roof. And as drones can cover more ground compared to cherrypickers, this saves time and money as you will not have to block the street for days, and human error is eliminated as you will not need to worry about replying on a inspectors' memory and notes
  • Provides accurate and detailed roof geometry reports: Our fleet of RTK-equipped drones can cover more area compared to traditional methods, all while eliminating human error in calculations, and producing permanent, irrefutable evidence of the roof’s condition at that precise point in time. We produce thorough roof inspection reports with 99.4% accuracy which includes the full geometry of the roof: slopes, measurements, gradients, etc. We can also measure the tile gauge, letting you know how much the tiles overlap
  • Full integration: The reports we create are available in different formats allowing for full integration with DXF, CAD, AutoCAD, and BIM as well as, video and photographic evidence
  • Supports Machine Learning (ML): Machine Learning allows us to track your roof's repair progress and identify discrepancies with repeated inspections of the same roof over the duration of the project
  • Reduces your energy bills: By attaching thermal cameras to our drones we can deliver you thermal reports to help you cut down your energy bills and identify how energy-efficient your assets are e.g. drones allow us to pinpoint and detect damage on solar panels and identify areas where your roof is leaking precious heating
