Tin Roof Recommendation

[Lightspeed]

We considered these, but for rainwater harvesting we decided the risk of leached metals was too great.

Bear this in mind, if going down this route.

Our system has a kind of acrylic inert surface that will resist acid content of rain. It also resists moss and lichen growth, so the water coming off it is not picking up any secondary contamination.

For drinking roof harvested water we both filter and boil before consuming.

The dew collecting capability has been a surprise to us, and very useful of course. So as not to mislead, the roof is quite large ( in the order of 250 sqm) so it has a good sized area of capture. Also the ability to harvest water from dew is very much location specific, and needs to be considered an opportunist and occasional source rather than a reliable one.
