Can’t complain. viewtopic.php?t=86597 Re: Tiled roof or Colorbond !? 22Mar 24, 2018 12:13 am Just realised that I missed your choice post, apologises I don't get every notification for some reason. As per my first post they both have pros and cons, plenty of room for both products in the market. Best wishes for a smooth build. Re: Tiled roof or Colorbond !? 23Mar 24, 2018 8:37 am Actually, there's another argument in favour of Colorbond roofs for those with rooftop PV solar - solar panels become less efficient with increasing temperatures (it's called the "Max Power Temperature Coefficient" and varies from between brands and models, but 0.4 seems to be a reasonable average, which means that a typical solar panel will lose 0.4% of output for each degree centigrade above 25). During the warmer months, tiled roofs will collect and absorb more heat during the day than a Colorbond roof, with the difference in temperature being greatest in the mid-to-late afternoon - i.e. having a tiled roof will potentially be causing a loss of PV output during a peak demand period. I hadn't actually considered that potential until now; it'd be interesting to run the models and see how big the potential PV generation loss in a peak summer afternoon with a tiled roof vs a Colorbond roof actually would be, and what financial impact that'd have over the longer term. Re: Tiled roof or Colorbond !? 24Mar 24, 2018 8:56 am It also occurs to me that I haven't mentioned building for the OP's climate. Perth is in Climate Zone 5 (Warm Temperate), with mild winters and hot summers (see the [url=http://]yourhome.gov.au[/url] website for an introduction on designing to climate). In this climate the best response for all-round energy efficiency and comfort is internal thermal mass insulated from the outside - basically, best practice is to not have masonry (bricks and tiles) outside your insulation layer. In typical Australian practice, the traditional Perth approach of double-brick with a tiled roof is not the best suited to the local climate. Colorbond roofs with their lower external mass and better insulation are a better approach (as is using reverse brick veneer instead of double brick walls, but that's another topic altogether). No, I even have sections of narrowness where the tiles won't slide up any further. When I manage some spare time, I might play around with the first DIY part of my… 7 4926 Thank you so much. We ended going with the terrain that’s part of our brick. 2 2534 Your house roof does not show rusting other than some surface rust on the flashings. In my opinion you dont need to replace or paint the roof other than treat surface rust… 1 10206 |
