01
Start with the structure
Traditional slate is heavier than many common roof coverings. An experienced professional should evaluate the roof framing, deck condition and project-specific load before material is ordered. Lightweight real-slate systems may be useful where conventional weight is a concern, but they still require proper design and installation.
02
Match the slate to the roof
Roof pitch, slate length, exposure, headlap, thickness and flashing details work together. Color and texture matter, but they come after water-shedding performance. A good specification identifies the actual product, testing and installation requirements.
03
Plan for long-term ownership
Natural slate rewards proper maintenance and repair. Homeowners should expect periodic inspections of flashings, valleys, penetrations and isolated broken pieces—not routine replacement of the entire field. Access to matching slate and a qualified slater should be considered before installation.
