Application of the waterproofing membrane should be considered over all substrate surfaces. Most waterproofing professionals require that the waterproofing membrane cover the entire substrate (most commonly concrete) including the footer.
A
standard detail on a steep-slope residential roof application involves flashing
at masonry chimneys. Proper detail design is required at this critical
component to provide waterproofing protection.
In specific situations where the structural roof deck is not attached to the wall and an opening is provided, a roof-to-wall expansion joint is required. The installation of the roof-to-wall expansion joints allows for differential movement between the two construction components.
The
most critical component of paver application on sloped surfaces is the correct
adjustment of the pedestals. Adjustments of the pedestals are required to
provide a uniform and level paver height while adjusting for changes in substrate
height based on slope.
In an inverted membrane system, the conventional membrane arrangement is inverted or turned upside down. Inverted roof membrane assembly (IRMA) systems are used in applications where the membrane requires protection from site-specific hazards.
Edge flashing is the most critical component of a roof system, particularly in high-velocity wind regions. The majority of wind damage and roof blow-offs are initiated at the perimeter edge.
