If you’re planning on installing a new roof on your home, you need to know exactly what is roof flashing. There are three types of flashing: Fascia, Continuous, and Step. Each type has its own advantages and disadvantages. If you’re not sure which type is right for your home, read on! After reading this article, you should be aware of the different types of roof flashing. Whether you’re installing a new roof or making repairs to an existing roof, it’s important to know what you’re doing.
Fascia flashing
Roof flashing is essential for protecting your home’s edges from water damage. There are different types of flashing and methods to install them. One common type of roof flashing is continuous flashing, which is made of a single piece of metal and carries water down to the shingles. Another type of flashing is called parapet flashing. It is a thin strip of impervious material installed to cap vertical sheets or masonry walls.
New roofs typically have a piece of roof sloping down from the roof, which covers the top part of the fascia board. Decorative bed mold is not a common feature on newer houses, so a wide piece of roof flashing can conceal it. When choosing a new roof, make sure the color of the flashing matches the house’s trim. If it matches the trim color, this step can be skipped.
Fascia flashing protects the structure underneath the roof from water, preventing the water from flowing down the wall or into the building below. It is used in conjunction with shingles to divert rainwater into gutters. Whether you’re building a new home or repairing an existing one, it’s important to follow the proper installation instructions for flashing. You’ll be amazed at how easy it is to install and maintain roof flashing.
Continuous flashing
Typically, continuous roof flashing is made of galvanized steel or aluminum. It should be installed over all transitions from roof to wall, including skylights, dormers, and one-story attached sections. When flashing is not installed, water may leak onto shingles, damaging the roof. Proper installation also protects the pipes from damage. Listed below are a few tips for proper flashing installation. Read on to learn how to install continuous roof flashing.
A continuous roof flashing system protects the entire roof from water and vapor. The flashing is often installed to keep a cavity in the roof that prevents water seepage while providing air circulation. It is usually 3/8 inches deep, and is essential to the integrity of a rainscreen. The flashing should be installed in layers to avoid water damage and prevent water from penetrating the wall. The final layer of protection is the air and vapor barrier (also known as an air and water barrier). This material is either permeable or non-permeable. Any holes or punctures in the outer cladding must be sealed to prevent moisture from entering the cavity.
When installed correctly, continuous roof flashing prevents water from penetrating the roof’s interior. It also protects the interior of a building from water damage. Continuous roof flashing is especially crucial in areas where the slope of a roof meets a vertical surface, such as a chimney or skylight. Without proper flashing, water can seep through, leading to roof leaks or shingle erosion. Fortunately, continuous roof flashing has many advantages, including being attractive.
Step flashing
Installing step flashing on a roof requires some skills. You will have to bend the flashing by hand to form a rounded crease down the middle, leaving more room behind it. You must also install the step flashing at the bottom of the slope, because water will roll down it. Then, nail the next piece of flashing over the nail head. In this way, you will ensure that the step flashing is secured to the roof.
The step flashing can be purchased pre-cut to fit the length of your shingles. The length is generally 5'’ x 7'’, so you can overlap the pieces. Pre-cut step flashing is sold in 100-packs. To install it, cut a small strip at a time and follow the instructions on the package. This will save you time and money. It will also make the job go faster and better.
You can install step flashing in one or two courses. Install one step flashing per course of shingles, and then fasten the vertical flange to the surface of each shingle. When installing the step flashing, be sure to overlap the siding and install the next course of shingles on top of the step flashing. A typical length for a step flashing is 2 inches longer than the length of the exposed roofing material, for a minimum head lap of 2 inches.
