Leaky Roof Deck in Ontario in Need of Repair
Leaky Roof Deck in Ontario in Need of Repair Causes Conern for Homeowners
The Problem: Water Leaking Through Light Fixtures
Since first moving into their new home, the homeowners experienced water leaking through to some light fixtures. A big concern that they wanted resolved as quickly and economically as possible.
When they had the shingles replaced on their primary sloped roof, they inquired about the flat roof over the addition.
The existing flat roof deck’s exposed surface was carpet! There was no waterproofing detailing at all. Their roofer referred them to Duradek for an attractive single-product waterproofing and walking surface solution—perfect for a deck over living space.
The homeowners inquired with thier local Duradek installers, Dykstra Bros. Roofing. Considering all of their roof deck options, they also got a quote for 2-ply torch-on roofing. Torch-on roofing is not meant to accept pedestrian traffic, so with torch-on, they would need to add a separate walking deck surface.
They chose Duradek’s time tested waterproofing solution to protect their home and had Dykstra Bros. Roofing take a closer look at the project.
Solving a 5-Time Leaky Roof Deck Problem with One Reliable Product – Duradek
Dykstra Bros. Roofing removed the old, failed deck surface and made a shocking discovery. There were 5 repeating layers of carpet, torch-on, and plywood underneath — about 50 years of failed waterproofing history to remove!
Once removing all of the layers of failed roofing (and non-roofing) products, the installers could see that the leaks were coming from the deck/wall intersection. This is a point of waterproofing vulnerability and a common issue when deck waterproofing is not handled by a trained professional familiar with the building envelope.
They installed fresh 3/4″ untreated plywood and perimeter drip flashing. It is important to use only untreated plywood with vinyl membrane waterproofing as the chemicals in treaded wood will react with the vinyl.
Then Duradek Heritage Aspen vinyl decking was applied with proper care to waterproofing details where the deck meets the wall. This included removal of the siding and extending the membrane 6″ up the outside wall at the inside perimeter of the deck.
Old wooden railings were replaced with a Durarail aluminum picket railing system for a perfectly finished, low maintenance deck. The railings were fascia mounted which does not penetrate the surface of the membrane. This means an already low maintenance deck has one less point of homeowner maintenance with no need to annually inspect the caulking around surface mounted posts. The only maintenance needed to keep their deck looking great is to clean as recommended.
Adding Durarail aluminum railings from thier Duradek installers provided the homeowners peace of mind with complete waterproofing integrity with functional style – and a single-source warranty.
