Regular roof inspections are a common sense way to look after your key asset. Yet it is easy to sometimes miss when ‘up above’ isn’t ‘up to standard’.
Flat roofs aren’t always visible and the danger of an ‘out of sight, out of mind’ attitude can lead to temporary neglect, lasting damage and costly repair bills. Sometimes property managers only realise there’s an issue after strong winter rain.
There are a few things to look for before that happens.
1. Flaking or fading paint.
Wear to the integrity of the surface protection can quickly lead to larger issues before you know it. With a sound maintenance plan paint conditions can be regularly checked and assessed.
2. Missing nail heads.
Tiny holes in roofing can result in big headaches. Missing nail heads are one sign that there may be problems below – with small leaks from these areas causing mould and rot below.
3. White or red rust appearance.
Rust is the most obvious sign that maintenance needs to take place. A ‘dusting’ of red rust may be prevented from getting worse with a careful paint – any more and you’ll be looking at replacement costs. White rust is also common on commercial buildings in New Zealand – particularly in coastal areas (it’s caused by salt deposits in areas where rain wash doesn’t reach). White rust is often harder to spot than its red cousin, but just as damaging.
4. Moss growth.
Things grow where water collects. Moss is the most obvious visible sign here. By holding moisture moss speeds the wear of the surface, particularly in our freezing temperatures when frost damages the coating.
How do you avoid these issues? Regular washing is a great way to save long-term costs, there’s a reason why it’s recommended by roofing manufacturers. It’s also a good idea to get your roof properly assessed by experienced experts. Only with the right equipment, correct processes and attention to detail can you get a cost-effective result.
Sometimes commercial roof repair and repainting can be covered by a manufacturer’s warranty too. If you’re unsure about whether your roof may be eligible for this assistance we’re happy to help here. We can also put your roof on a yearly plan for the best ongoing peace of mind.
