Slate

A slate roofing lasts more than 100 years. The slate roof is waterproof and won’t burn. It resists mold and fungus.

Quality does vary widely, so ask whether they passed the ASTM D3161, Class F (110 mph) or ASTM D7158, Class H (150 mph) wind tests, and the AC438 durability test. Upfront costs are low, but you should expect to replace the shingles after about 20 years or less. Shingle roofs have a lower life span in Florida due to the environmental conditions the material is exposed to.
