How to Choose Roof Flashing for a Successful Installation

If you’re considering doing a roofing project, you’re probably wondering how to choose roof flashing for a successful installation. Luckily, there are several factors to consider when choosing suitable materials. Here are a few things to consider: material, application method, and location. Considering the weather in your area, you may want to consider roof flashing with a galvanized base and a protective coating.

Copper

When choosing aluminum roof flashing by Klauer, ensure that the material is appropriate for the application. Copper is strong, malleable, and resistant to the caustic effects of mortars. It is also corrosion-resistant and will last for more than a century if properly maintained. However, paying attention to the proper installation of copper flashing is essential, as improperly installed flashing will increase the risk of a roof leak. 

A successful installation includes addressing loose flashings, skylights, chimneys, and other potential sources of rainwater runoff. Copper roof flashing can increase the aesthetic value of a home. While it is expensive up front, it will enhance your home’s curb appeal and age beautifully. You should consider copper if you can afford to pay the extra money.

Plastic

When choosing plastic roof flashing, you should consider the weather conditions your home will experience. Changes in humidity and temperature can cause your roof to move, and you need to choose a material that will accommodate movement without sacrificing waterproofing. While copper is ideal for this application, it is also expensive. Many homeowners choose plastic flashing for its lower cost, but it does not perform as well as metal sheet flashing.

You can test the water-tightness of your new roof by using a hose. Place the hose on the roof above the pipe vent and let it run for about 15 minutes. Once you’ve tested the plastic roof flashing, you’ll have a better idea of how well it fits and is effective. If you have any doubts, contact a professional roofer.

Step flashing

Step flashing protects the walls on your roof from water intrusion. It is also commonly known as collar flashing. Step flashing extends four inches up the wall from the roof deck and integrates with the drainage plane. Unlike continuous length flashing, step flashing is installed before the roof felt and shingles. If you’re installing a new roof on a shingled roof, you can use continuous length flashing only on the front wall, and neither style of flashing should be used on side walls.

It’s important to note that a step flashing is required on the sidewalls of a tiled roof, especially when the flashing is continuous. This flashing features a lip on the flange that extends below the tile and provides a water channel. Manufacturers of shingles require step flashing on sidewalls to protect the roof and prevent water damage.

If you’re installing a new roof, you’ll need to select the proper step flashing for the project. In general, it’s best to install step flashing over the shingles, so it’s not exposed. You’ll also need to install vent flashing, which will overlap the next row of shingles. Once you’ve installed the step flashing, you can proceed with the shingling. Remember to install it halfway past the vents and run it over them.

Continuous flashing

If you are thinking about repairing or replacing your existing roof, you should consider continuous roof flashing. It will reduce the exposure to temperature changes and create a barrier against the elements. However, there are many things to remember when putting in continuous roof flashing. Contact a local roofing contractor for more information. They can help you install roof flashing professionally. 

First, you must understand the purpose of continuous roof flashing. When installing a plumbing vent, you should ensure that the flashing is large enough to cover the vent. A good rule of thumb is that it should be slightly wider than the diameter of the vent. Afterward, it would help if you alternated the flashing and shingles. After that, you should use a sealant to hold the piece of continuous roof flashing in place. When installing a chimney, you should also use continuous roof flashing when sealing the intersection between the chimney and the roof. You can apply roofing cement on the chimney flashing and secure it with nails or roofing cement.

When installing roof flashing, choose the suitable material for the job. There are many different types of flashing that you can use. The most durable is metal, but it is expensive. Copper is the most common metal flashing material ages gracefully with a green patina. Copper flashing also does not need regular treatments and is durable and easy to install.
