Page 46: Appendix F: Sm Butyl Attachment Installation
5°F or above 180°F. WARNING • SM Butyl attachment must be installed on a clean, dry surface to ensure flashing integrity. Installing attachment on uneven surfaces, shingle gaps or overlaps, creates a risk for water leakage due to gap created between the adhesive and roof NOTE: surface. - Page 47 3. If three or more screws miss the rafter, then follow the direct to deck installation CAUTION procedure and reduce the attachment spans as per Unirac direct-to-deck • To determine if the screw is engaging the rafter, there should be resistance recommended spans for roof attachment.
- Page 48 Note: • Additional deck screws are NOT included in the KIT. Must be purchased separately. • Maintain stock of additional deck screws from Unirac Kits in case of direct-to-deck installation. CAUTION 1. Allowable attachment spans may change for direct-to-deck applications.
