Adhesives for Metal Roofs
With the adhesives that are available today, the
attachment of clips to metal roofs can be as reliable
as screws or nails into a wooden roof. The adhesives
that perform the best allow some flexibility in the
connection between the clip and the roof surface.
Adhesives such as epoxies, which cure to a hard
nonflexible form, should not be used. Acid-curing
silicones, which are not as strong and could damage
the roof, also should not be used.
The adhesives listed below have been evaluated by
Thermal Management.
