Natural vs. Synthetic Slate
Natural slate ($15-$40/sq ft) is quarried stone with a 100-200 year lifespan. Synthetic slate ($8-$15/sq ft) is made from rubber, plastic, or fiber cement and lasts 40-60 years. Synthetic options weigh 75% less and are much easier to install.
Color & Grade Selection
Slate comes in black, gray, green, purple, and red. 'Hard' slate (S1 grade) lasts 75-200 years, while 'soft' slate (S2/S3) lasts 50-125 years. Vermont and Pennsylvania produce the highest-quality American slate.
Finding Qualified Installers
Slate installation is a specialized craft. Improper installation is the #1 cause of premature slate roof failure. Always hire contractors with specific slate roofing experience and ask for references from completed slate projects.
