When it comes to protecting your deck, many homeowners know the importance of waterproofing the surface of a deck. In fact, waterproofing a deck is one of the leading ways to maintain the integrity of a deck. However, not many homeowners know about the importance of deck flashing. Here is why proper deck flashing installation is necessary for the integrity of your deck.
Deck flashing refers to the layer of material that goes between your deck and your home. Despite its importance, there are a number of decks that don’t come with flashing. The reason that flashing is so important is because it prevents water damage from occurring between your deck and your house. Even with a concrete deck, flashing is necessary since corrosion can occur on the metal fasteners that hold your deck together and the place of contact between the deck and the house is still an area that can be damaged. If this place of contact is not properly taken care of, it can result in mold or mildew forming between your home and the deck. Not only does this weaken the integrity of the deck, it can also be very time consuming and expensive to fix.
There are a variety of materials that can be used for flashing. Aluminum is often used as it is easy to form, relatively inexpensive and durable. However, aluminum will eventually corrode if in contact with fiber-cement siding. Copper and lead-coated copper is another good material to use though it is harder to form than aluminum. Despite this, copper is an extremely durable material and will last for a long time. PVC is another material that can be good to use because it is easy to work with and also durable. Deck flashing is an important part of deck maintenance and safety and should not be avoided.
