PROJECT:

Residential Roof Deck Leak Solution – Simcoe, Ontario

PROBLEM:

This wood deck was situated over living space and had two methods of moisture management in place, yet it was still leaking in all of the critical detail areas.

165-front

This roof deck had leak issues despite a 2-phase waterproofing system.

The first level of protection was waterproofing through a traditional felt and tar on the roof under the deck boards. The secondary water management approach was utilizing a ceiling system that caught water and re-routed it to a trough. While his was intended as a ‘back-up’ system, it was clear that neither approach was working to protect the living area below from leaks.

2 phase waterproofing with felt and tar on top and trough system below could not provide adequate waterproofing.

DURADEK SOLUTION:

Duradek Dealer, Lakeview Deck and Rail knew what needed to be done to resolve the leak issues for good.

To start, they tore off all of the existing deck and failed waterproofing. They established a slope with new framing on one foot centres, and installed all post blockings.

Substrate preparation requires untreated plywood which is an environmental advantage over chemically treated wood

The new substrate was prepped by sheeting 3/4″ select fir T&G plywood and filling all joints to make it perfectly smooth for the application of the Duradek Ultra Cork Macchiato vinyl. Lastly, the installation of an aluminum picket railing system gave the homeowners a beautiful, low-maintenance new deck.
