Ballasted roof dead load bamastrucpese structural 20 jun 14 15 41 i don t remember where i found it but i did some research a couple years ago when working on a project with existing roof ballast and came across a note that said 10 psf was the minimum dl that could be used for roof ballast. Roofblok ballast pavers create a smooth nonskid walkable surface that permits foot traffic on maintenance patio and terrace areas while protecting against scouring vandalism hailstones ultraviolet rays and other forces that might tear puncture. By using an elevated paver system water is channeled away from the roof surface reclaiming lost space. Second a drainage mat must be installed between the roof surface and the paver grids.

First the roof deck must be reasonably flat without major dips or undulations minor ones can be shimmed so that the pavers are level. Roof pavers of either porcelain or ipe wood supported by adjustable height deck supports vastly expand options for building rooftop decks as well as significantly simplifying site preparation delivery of materials and construction. See roof plan for roofing by others 1 4 spaces max. Roof surface shall be non compressable and designed to carry the loads that the pavers will apply when fully loaded as per design.

Our porcelain pavers are comprised of a 20mm single layer of light weight load bearing porcelain designed for use in conjunction with raised pedestals on roof decks. The wide diameter flat base roof paver supports avoid damage or penetration of existing waterproof membranes. There are several brands of drainage mat. The dead load weight of field applied stone ballast varies dramatically.
