Roofing Facts
What Affects How Long Roof Paint Lasts
The lifespan of roof paint in Tasmania depends on several factors, from the condition of your roof to our unique coastal climate. Here are the key things that can affect how long your roof coating will last.
Preparation
Paint over moss residue or a damp surface fails early. This is the biggest single factor.
Number of Coats
One coat rarely reaches the film thickness manufacturers specify.
Roof Material
Sealed concrete tile, well-primed metal and correctly primed terracotta all hold the coating well.
Exposure
Coastal salt, high wind and full sun all wear coatings faster.
Colour
Very dark and very bright colours show fading sooner.
Shade and Moss
South-facing and tree-shaded roofs in Hobart stay damp longer and grow moss faster.

How to Make Roof Paint Last Longer
01
Keep Gutters Clear
Prevent water buil-up and debris.
02
Trim Overhanging Branches
Reduce shade and keep your roof drier.
03
Treat Moss Early
Remove moss and lichen before it spreads.
04
Check After Major Storms
Look for damage or loose paint.
05
Clean Annually
Remove dirt, salt and airborne pollutants.
Paint, Restore or Replace?
If the coating has failed but the roof itself is sound, repainting is usually the most costeffective option. If tiles are cracking or metal is rusting through, read should you paint or
replace your roof.
