5.2 Installing the substructure
Laying the sealing strip
Mounting steps:
• Unroll the sealing strip along the lower edge of the
uncovered roof surface.
• Cut the sealing strip for the length of the surface area +
one extra tile width on the left and right.
• Allow for adequate spacing (50 mm) between the
upper edge of the roof tile and the lower edge of the
corrugated metal sheet to avoid an edge that is
too sharp. Also allow for adequate overlapping by the
corrugated sheets.
• Fix the sealing strip on the additional roof battens with
screws.
• After fixing the sealing strip, adapt the shape of the
strip to the shape of the tiles, taking care to avoid the
formation of sharp edges.

Leaky construction
If the sealing strip does not
sufficiently overlap the roof tiles, the
roof may become subject to leaks.
• The sealing strip must vertically
overlap the tiles at least as much
as the tiles overlap themselves.
In case of very curved roof tiles, it
may be advisable to flatten the
upper edge of the tile underneath
the sealing strip prior to laying. In
that way, sharp edges and water
accumulation can be avoided.
