For an Olympia roof, natural slate is quarried stone; synthetic slate is a manufactured look-alike. Natural slate’s weight makes roof support an early design decision, while a synthetic product must be evaluated by its own material and technical data.
A steep-slope roof with structure and support suitable for the selected slate product and installation system. Natural slate can be heavier than other roof coverings and may require structural review.
What changes the decision?
Natural slate preserves the character of real stone, and its weight calls for structural review of the specific roof.
Synthetic slate can create a similar visual pattern with a different composition and installation system.
Compare unit weight, fastening, underlayment and flashing for the exact natural or synthetic product.
What is the difference between natural and synthetic slate?
Natural slate is quarried stone and can place substantial weight on the roof structure. Synthetic slate is a manufactured product designed to resemble it; composition and weight vary by model. Compare technical data and have the structure checked for the chosen assembly.
What should a slate roofing proposal name?
Identify the slate source or product, unit size and thickness, fastening, underlayment, flashing and roof details. The written scope should also state how broken or unsuitable existing slate will be handled.
What should I check before choosing natural slate?
Confirm the structure can support the selected stone, then compare slate size and thickness, fastening, underlayment and flashing. These choices shape the roof as much as the color does.
Which slate roofing options should the proposal identify?
Natural slate
Quarried stone roofing; the selected stone’s weight, fastening and support needs belong in the roof design.
Synthetic slate appearance
A molded or composite roofing product designed to resemble slate; its material, weight and fastening depend on the model.
Defined slate repair
A repair proposal should mark the affected area, slate units and connection details, plus explain how replacement material will compare with the existing roof.
More than the visible surface
A roof is a connected assembly.
The covering works with the layers beneath it and the details at every edge and opening.
Roof coveringThe selected material and its fastening or attachment system.
Water-shedding layersCompatible underlayment or membrane details, edges, valleys and flashings.
Roof deck & structureThe sound, prepared substrate that supports the selected system.
The building beneathVentilation, insulation and interior protection coordinated with the roof work.
