If you’re in the market for new roofing material, you might want to consider what is roofing flashing? It’s often confused with solar arc flashings, which is a different type of flashing. There are aluminum roofing flashing as well as asphalt shingle shingles, though. Asphalt shingle shingles obviously need a lot of maintenance and is easily damaged, but if you look for cheap alternatives, they’re actually quite affordable when compared to other choices.
The difference between these two types of roofing materials is in the flashing that seals the joint between the roof shingles and the plywood or tile wall surface. A chimney is probably most commonly thought of as a place where a house exudes heat and smoke, although this isn’t the only use of a chimney. It’s also used to vent household air, and may be visible from the outside or from an upstairs window. In all of these uses, flashing is important. Without it, the roof will rust and deteriorate. But it can also prevent rainwater from reaching your home, keeping your chimney clean and working properly.
Chimney blowers, or chimney covers as they’re more commonly known, are installed to make the flue easier to regulate. Water that seeps into the roofing system at the top, through a crack or other opening, can be directed away from the house and away from the walls. If left unchecked, water can pool around windows and doors, damaging them and possibly causing them to collapse. A blower can help prevent this water accumulation by acting as a damper, slowing the water flow down and out of the roof covering.
Roofing flashing is really quite simple once you understand its basic function. Flashing is usually comprised of a flexible metal rod attached to three to four sheets of weatherproof metal mesh. The flexible metal flashing is then rolled onto the roof shingles and attached to the top of the flashing pan with hooks. When installing a flashing system, always make sure to install the flashing from the bottom upward and in the direction of the house’s siding.
There are a number of different types of roofing flashing to choose from. Flat flashing, gutter flashing, pitch flashing, and shingle flashing are a few of the different types available and each one performs a specific job that must be performed in the correct manner. For example, pitch flashing is used to provide an extra layer of insulation in the roof system for added protection against heat loss. Some flat roofing systems use flashing as a form of venting, which allows excess moisture in the attic to escape and get transferred outside the house where it can potentially damage the interior wood framing.
One last thing that is worth mentioning about roofing flashings is their connection to the roof chimney crown. The chimney crown is actually the most dangerous point on any roof system because it is sitting directly on the home’s living space. Flashings are important because they help to contain the amount of heat that can escape from the home’s living space through the chimney and up into the living space. Always remember to consult a professional chimney sweep when deciding what type of flashing will be best to install on your chimney crown.
