Some pictures from DVD video I took just before the roof was painted:
showing how bad the quality of their work.
I arrived at 6AM and took the photos and videos.
From the pic looks like they repointed, you can see a nice smooth finish on the
pointing that has been painted.
But they have left the edge of the roof which should have been covered with flexipoint,
Flexipoint is what they use as pointing these days they don't use mortar anymore.
The machine for cleaning looks like a big round disc floor cleaner but with high pressure water.
Some companies use them other not.
I'm sure there are good roof restorers out there but few and far between.
I have just completed my parents roof myself first using a gerni then a dozen
bottles of bleach sprayed on, then two coats of build up primer then two
coats of top coat.
Total coast around $4000.00 for a big 300sq metre roof, and this included
a professional roofer to repoint.
Looks like a new roof again after 42 years.
I think you will only get a good lasting look if you use darker gloss colours,
looking at some older roofs that have been repainted lighter colours they tend to
become dirty looking after a few years and moldy is a flat finish has been used. .
I went with Nutechpaints which is manufactured in Melbourne and use
teflon in the manufacture of their paints.
