While somewhat more technically demanding to install than other aspects of roofing, flashing is essentially a simple material with a simple concept. In addition to other parts of the exterior of a home, the roof has many joints where moisture can easily enter. With increases and decreases in temperature, these joints expand and contract periodically. The purpose of flashing is to create a protective layer that seals off the joint from water. Roseville roofing contractors can discuss all the options available in flashing for a new roofing installation or repair.

The roof exists to protect the interior of the building. With this in mind, flashing works to provide a seal to each joint from water. Because water damage accounts for most of the damage to homes as a result of weather, the job of flashing is absolutely vital. Flashing is installed at multiple points along the exterior of the home, but the roof is one of the more prevalent locations. With chimneys, skylights and parapets along the roofline, each of these areas consists of a joint that must be sealed and protected against water.

The flashing is a simple material made of different types of metal. The optimal metal is one that can easily be soldered or molded. In addition, a metal that is non corrosive is preferable for the purpose of durability over time.

Two major types of flashing are base flashing and counter flashing, officially known as cap flashing. Base flashing connects to the roof itself and can be woven into the roofing material. Counter flashing connects either to the extended part of the base flashing or the wall.

The flashing will be applied differently based upon the type of roof. Regardless of the roofing material, the purpose will be to seal off the joint area and prevent water from entering the house. As mentioned before, the installation of the flashing is a more technical process as compared to the rest of the roofing. If improperly installed, the flashing will bind up and provide inadequate sealing of the joints.

The best time to discuss flashing is with the installation of a new roof for peak protection. Regardless of when the conversation occurs, a roofing professional will be able to discuss the multiple options in flashing and, if necessary, provide repair or new installation. One factor in determining if a new roof is needed is by looking at the flashing. If they are beginning to fail, then it may be necessary to look at an entirely new roof or section of roofing.
