Red slate roof, perhaps from the Granville NY quarry are shown at below-left. We don't know how long this superb material will last as we've never found one that was worn out on a roof in the U.S. but a rated life may be 300 years. Our second red roof slate photo (below right) illustrates a mix of red slates from the Granville NY quarry and ribbon slates on a home on Clinton St. in Poughkeepsie, NY.
Rusty Red Roof Slates
Below we show red-looking slates on a home in Poughkeepsie, NY. Rust-stains on roof slates may turn some slates red below rusting steel flashings. Our second rust-stained roof slate photo (below-right,Putney VT) is quite clearly showing rust staining on roof slates from a rusting ridge cap. But other roofing slates are naturally rust colored as we show below at Rust-colored Slates from China
Ribbon Slate is roofing slate with linear colors running in stripes through the slate material. Often the "ribbons" are diagonal depending on how the slate was quarried.
References about slate roof durability, at least among home inspectors and some slate books, claim that ribbon slates were inferior and likely to have a shorter life due to their mineral inclusions. However in New York one of the authors (DF) has observed ribbon slate roofs which appeared to be in good condition after 80-90 years. The inspector needs to examine the specific roof to determine if the ribbon slates involved are deteriorating from mineral wash-out or alternatively if they are in good condition.
