Slate Roof membrane is used under slate roofs, this roof membrane is bituminised roofing felt, faced over half its width with a heat-laminated layer of aluminum foil.
Waterproofing layer laid under slate roofing tiles.
Effective coverage per roll: 4,0 m².
Starting at the lowest point of the slope of the slate roof , roll slate roof membrane out across the roof parallel to the eaves.
The aluminium foil strip must face upward on the lower half of the slatex.
The Slate Roof Membrane is then nailed, with large headed copper clout nails, through the unprotected felt, onto a batten. In aggressive coastal environments it is safer to use Muntz metal nails if available.
After slating over the aluminium area the next strip of slate roof membrane is applied in similar fashion so that the aluminium foil coated area of the second sheet overlaps the uncoated strip of the first sheet.
Work proceeds up the slope of the roof until the entire area has been slated. End laps in the felt must be overlapped by a minimum of 150mm.
