DrySnap - Under Deck Rain Carrying System

DrySnap Materials Calculator


TO ESTIMATE DRYSNAP MATERIALS FOR A JOB, SIMPLY FILL IN ALL (3) REQUIRED FIELDS FOR EACH APPLICABLE SECTION OF THE DECK. From ledger wall to outer beam is one section. If there are multiple sections, calculate each section separately. Enter cantilever area separately.

** NOTES:

1) This materials estimator based on traditional square decks.

2) This materials estimator is based on joists spaced 16" on center.
Variation of joists spacing will directly effect the number of pitch spacers and deck screws that will be required.
For joists spaced 12" on center, multiply the total number of pitch spacers and deck screws estimated by: x 1.2

3) This materials estimator uses a 50/50 ratio of 2 1/2" and 3" as an example.
Depending on the total number of rows & spacers/row, you should use your own discretion for proper screw sizing.

4) Items needed but not included in this material estimate: Gutter System, Finishing Trim for Exposed Sides, Flashing, Caulk.

5) The DrySnap system is designed to collect and drain the water falling within the length of the panel.
DrySnap is not guaranteed to be 100% watertight. If that is the desired result, or for full room enclosures and the area above the beam, additional steps may be needed.
