it's possible to have a tiled or steel roof painted and the product, if applied well, should last for many years and can be reapplied if necessary..like any painted surface...not aware of any other product except these roof paints but, if your roof is already 30 years old it's probably time to have it checked for any potential weaknesses ...what is the roof made out of?

It is just an aesthetic thing, but it would annoy me everytime I see the front portico. It makes the portico look like a poorly considered add-on with differing roof pitches for no good reason. It looks like the new wings either side of the portico will match into the existing house well and will be well integrated into the existing roof structure. You need to decide as soon as possible if you are going to live with it and ignore it, or halt the work on it and pay for new roof trusses that match the other roofs. The more work that is completed on the portico the more expensive it will be to change. In this case procatination in making a decision may cost you big dollars.

Could you put a photo please?

(echoing others here) No, no, no NO! ............The issue isn't the brickwork nor the roof tiles.....rather it's the currently multicoloured trim of say your guttering, garage and windows etc... I'd also argue that the idea of the "award winning" example posted above, will most likely date in time.......although I like the landscaping aspect of that one - but otherwise it's too heavy tonally for my eye and the rear extension is a harsh juxtaposition formally........anyway,I digress.... On your home here I reckon you best to work within the inherent style rather than try and force it into something that it is not. Other things, some not that expensive, will go a long way here, for example, bring the trim colours into consistency, consider relocating the downpipe on the far left brick column, and focus on a proper front landscaping design (including removing the concrete aspect) and de-cluttering the verandah will also make a world of difference. Looks like you have a beautiful established (jacaranda) tree in your front yard - perhaps make that that the "hero" of your frontage / streetscape That's what I did on this project, whilst completely different style the point is it was more about the garden - the house and structure becomes supporting and complimentary to the external landscaped spaces Good luck!
