My favorite kind of roof is sod over a waterproof membrane.
Homemade clay roof tiles.
Tire tiles would be a fire danger too and much more toxic when burned than wood shingles.
While there are several retail cleaning products on the market using a homemade cleaning solution will be much more cost effective and work just as effectively as high priced commercial products.
Roof tiles have been made out of clay for years partly because they can be easily made.
By mixing just a few inexpensive household ingredients you can clean and disinfect the red clay tiles with ease.
I don t care for the so called green thin living roof structures as there isn t enough depth of soil there to do without added insulation nor is there enough depth of soil for the plants to survive if they don t get watered regularly.
When clay tiles have been properly made and hardened they are waterproof and light and can be painted to any desired color.
