Should I paint my terracotta roof?

January 23, 2016

This is a questions we are asked all the time, “Should I  seal my terracotta roof?” To put bluntly we think it’s a bad idea, but this all depends on who you talk to.
Over the years Terracotta tiles, like any roof, collect a build up of dirt, pollution, moss and lichen making it seem visibly unattractive. But what lies underneath those layers are generally beautiful beautiful tiles that once restored look amazing.

Some “I can do anything for money” roofing mobs like to push painting terracotta roof’s as it is more profitable for them than to have it simply cleaned and to make money off you selling a lie. Other than the obvious ethical issues of these practices,  there a few more problems with this.

You cant painted a glazed terracotta tile, that would be like painting over glass. The same applies for any attempt to add pop to a terracotta roof. The coating will eventually peal like PVA glue as it will not be able to adhere to surface.

What we suggest at Casey Roof Care is to have your roof inspected, cleaned and maintained. Depending on the age and condition of the tile, they can be prone to cracking under foot quite easily. The first thing we do is to inspect roof watercourses and existing flashing, repairing as we go. We then source your exact tile from recycling yards with the intention of leaving you will a surplus supply once we’ve finished. We will pressure clean your roof replacing any tiles and flashing as required. We then apply an anti-fungal primer to inhibit the growth of moss and lichen in addition to two coats of sealer. Once finished your roof will look like new again.

We believe this is the best approach to take. We have published more articles on Melbourne Roofing that you are most welcome to read. In addition we have full list of professional services offered by our local business or simply call on (03) 9028 8795 for more information.

If you are going to have your roof painted, we suggest visiting the Colorbond or Dulux websites .

    Thanks, this advice is much appreciated. I was just quoted for a roof repaint, and thought the salesman sounded a bit dodgy. I was thinking that a pressure clean was all I would need, but instead they tried to sign me up for an expensive repainting instead.

    I have been quoted $13,000 for a repoint, rebed, roof sealer on terracotta roof , no flashing replacement for a two story house. Got another quote for $8500 same but no sealer and one valley replacement-is this all too high? Variance is puzzling me? All feedback welcome.
