Why It’s Important To Have Properly Installed Flashing

Having a roof over your head is important. When that roof begins to fail for any reason, it can lead to problems inside of your home, especially if the roof is leaking when it rains or snows. Water damage can be a very destructive force on your home and the personal property inside of it. Fixing or replacing damaged building materials or personal items can get very expensive.

That’s why having a roof over your head is such a vital thing to have and so you must maintain it properly in order to keep it sufficient shape. One of the ways to do that is by having roof flashing installed on the roof of your home or business.

This is a necessary step to take to prevent water intrusion at some of the most critical areas of your roof.

Understanding Flashing

Flashing is a protective seal that is located at those areas of the roof where a projection exists. These are usually a chimney, a vent, or a skylight and if these intersecting areas are not sealed correctly, they can begin to leak due to the expanding and contracting that comes from a change in the seasons. As temperatures shift from one extreme to the other, this can cause small fissures and other damage.

But flashing is designed to keep that from happening as the seal is flexible and moves with these shifts so as to keep moisture from entering. Without it, you could be dealing with costly roof repairs.

Flashing Materials

Like any component of decatur roofing, the right materials are crucial to ensure the integrity of your roof. That’s why flashing can be comprised from a variety of materials. Metals such as stainless steel, aluminum, and copper are commonly as well as plastics and composite materials.

But metal sheet is the most resilient and stable of the possible material options available. Copper is the most popular because of its flexibility and capacity to adjust to even the smallest changes in weather temperature. Plastic is the cheaper alternative to both of these more expensive options because it can start to show signs of wear and tear more easily, particularly under constant direct sunlight.

The Importance of Flashing

Certain areas require strong resilient flashing, otherwise your roof will begin to crack and leaks can occur. It’s also imperative that you get the job done right the first time as a faulty roof installation can make your roof wear out faster.

Repairing or replacing the flashing on your roof is also a large job and it can be extremely inconvenient as a homeowner trying to live in the home while the work is being performed.

But this can all be avoided so long as the right materials are chosen for your particular roof. That’s also a critical factor to consider as not all materials are appropriate for all roofs. If the wrong material is placed on a roof that is not compatible with it, then you can start to damage your flashing.

Certain areas must have flashing applied in order to keep the roof watertight. The following are ways in which flashing can accomplish this task:

Skylight

One long piece of flashing is applied to the seams of a skylight in order to provide an impenetrable seal that keeps water from getting in through it.

Vents


Depending on the type of vent you have on the top of your home, you will need different types of flashing. But in whatever configuration you have it installed, the flashing will need to be located in a way that extends high enough to prevent water from getting in.

In some cases this is going to be below the shingles of your roof, in others, it will be overlapping the shingles but situated below the pipe of your vent.

Chimney


Much in the same way as your skylight, flashing will place at the intersecting seams of the chimney and the roof. Here it is placed below the shingles above the chimney and overlaps the row of shingles on the lower side of the chimney.

Water Intrusion

Flashing is vital for keeping everything dry in your home, especially in regions where there are higher than average rainfall. Without it, you can begin to suffer those hairline fractures that can only get worse as they are allowed to deteriorate. As that occurs, more water can leak in and the moisture can accumulate. That will lead to damage under the roof and possibly begin to reach further into the home along the upper floors.
