Why Flashing is Important for Deck Waterproofing Systems

 

Why Metal Flashing is Important for Deck Waterproofing Systems

Many times, homeowners looking to renovate their homes have pulled an aging door only to reveal siding, sheathing, and framing that’s consistent with colonies of ants and rotting wood. The lack of metal flashing leave the house without any means to prevent water from seeping in between the boards or supporting decks of the establishments. Most of the time, the resulting damage is not only destructive, but it’s also expensive and time-consuming to repair.

Flashing in simple terms refers to a thin layer of waterproof material installed to prevent water from getting into places it’s not supposed to reach. Metal flashing ensures water flowing from the roof, or other sources go straight to the ground without seeping through various cracks or gaps in the establishment. Building a waterproof deck cost money, but imagine the amount of money it would cost you on maintenance if you did not have a proper or any flashing system.    

Wood framed balconies are the worst hit in cases where flashing is absent, and evidence is usually seen through leaks, visible rot and destroyed finishes and worst of all concealed structural damaged from long-term water migration.   

The main benefits of flashing include:    

1. Prevents rotting

Water gives life. Also, water brings death. When a waterproof deck lacks a proper flashing system, water from the roof can easily find its way inside rough surfaces into various parts of the house.   

Flashing ensures instances of wood or plywood rot are unheard. The wood structure remains dry since the flashing takes away all the water and this also discourages inhabitation of destructive ants hence your plywood and the foundational structures are safe from rotting caused by water retention.   

2. Reduces maintenance costs

Nothing costs a builder or any house owner more than maintenance. On top of buying new materials for repair, the house owner has to tear down old material to establish new structures which can turn quite costly especially if the damage was far and wide. Flashing reduces the maintenance cost by reducing instances of rot of water destruction on the structure

3. Enhanced durability

Reducing rot cases also has another perk, strength of structures. The number one enemy to structures mostly is water. Keeping water at bay means your structures are safe from buildup moisture and hence safe from the rot and in turn increased durability altogether.   

In case you built your deck with absence of flashing, irrespective of the weather of the location, there are consequences for this failure, they include:   

Roof leaks and accumulated moisture   

Nothing feels nicer than relaxing on the high-level deck in the backyard. Now imagine if it starts raining and the roof starts leaking. Lack of flashing could lead to roof leaks which are unpleasant, and create a bad picture and tarnish the decorated ceiling or finishing and could in extreme cases result in foul rot smell.   

Possible deck collapse risk   

Sometimes things get stuck on the roof of the deck, and we have to climb and retrieve them manually. For weakened layers, possible collapse may ensue leading to serious injuries. Also, lack of flashing of the deck leading to rotting of the supporting board or plywood could result in the eventual collapse on its own due to the weakening of the underlying support structure.   

Reduced durability       

As mentioned earlier, too much water migration of the deck leads to rotting, which automatically translates to reduced strength. It doesn’t matter if the deck is waterproof, water still has a way to bring rot to the underlying structure and eat up to the whole deck.

Pooling water   

Waterproof layers may stop water from passing through, but cannot prevent water from staying. Pooling of water on the deck exposes the roof to eventual rot, or act as a site for breeding of bacteria or mosquito which is a health hazard. Contact us for more information.
