Weathered Vermont Green and Gray Slate

Vermont Green and Gray slate have an average lifespan of 175-200 years. Most of these slate that are on roofs today still have a lot of life left, and are well worth saving, even if the flashing is failing. New flashing can be installed and the roof will still outlast any shingle roof around.

Notice the shades of tan and brown as they age.

As they age Vermont Green and Gray slate develop shades of tan, brown, and red. We are frequently asked if this means the slate are old and need replaced. This is not often the case.
