Prefabrication Makes the Difference!

Every Sentry installed Duro-Last roof is custom your roof perfectly. Prefabrication eliminates up to 85% of the field seams required with other roof systems. Every curb, stack, and parapet wall is prefabricated for an exact fit for your building – making your roof leak-proof.

Custom Prefabricated Curbs & Stacks

Duro-Last’s patented one piece curb and stack flashings are made to the exact size of the units on your roof. This process eliminates labor related leaks, saves on-site labor casts, and provides a finished installation superior to all others.

Custom Prefabricated Walls

Wall flashing details of any height are prefabricated to fit each specific roof exactly, eliminating on-site labor and material waste. Duro-Last wall flashings are mechanically attached, avoiding the use of failure prone glue common to other systems.

Custom Prefabricated Deck Sheets

Prefabricated deck sheets in sections up to 3,000 square feet minimize installation time and reduce seam failures. Up to 85% of the field seams are eliminated - preventing future leaks and greatly reducing on-site labor costs and material waste.
