RESPRAYING YOUR ROOF
Exposure to UV, pollution and other environmental factors can take their toll. If you have a concrete tile, composite or metal roof, it will gradually dull with time. This should be expected, but is also easily fixed with regular respraying.
EFFLORESCENCE – WAIT, WHAT’S THAT?
Occasionally, natural salts within concrete roof tiles can migrate to the surface to form a whitish-greyish discolouration. It’s called efflorescence and it’s just a temporary cosmetic thing. You will find that it should disappear on its own over time.
Moisture means moss
Moss and lichen spores are everywhere in the air and they can settle and grow on most roofing materials. Moss and lichen grow only where there is sufficient build-up of moisture and dirt particles to support them. Removing the growth is easy. A quick turn with a low-pressure hose or a chemical solution will be enough to remove unwanted growth.
Check your gutters, downpipes and valleys
Uncleared gutters, downpipes and valleys are a common cause of roof leaks. You should give them an inspection regularly – at least once a year.
Painted roofs need repainting
If you choose to have your concrete roof painted you will need to respray it again every five years or every so often to retain that fresh-coat lustre.
It may make a lot more economical sense to consider retiling your roof with terracotta, where you will never need to respray your roof.
What to do about a leaking roof or broken tiles
If your roof or tiles need repair, it is always best to employ a qualified roofing professional to undertake the work. Walking on roofs can be dangerous and cause additional damage to your tiles.
