Roofs that are beautiful and designed to protect homes really well are those that have all the necessary components. When it comes to roofing components, among the most important ones for roofs are flashings. But what are they, exactly, and what do they really do for the roof as well as for the entire building structure? One of the most important things roofs are supposed to do is to prevent rainwater from finding its way into the home; flashings play an important role in this task. A complete flashing system “intercepts, collects, and discharges rainwater back into the roof’s draining system” so that moisture that can damage the interior components of the structure (which costs a lot of money to repair or replace) can be prevented from coursing through small entry points leading to the ceilings and interior walls. Roof flashings are usually installed in the following locations: Dormer walls, Chimneys, Roof valleys, Roof joints, Around skylights. The said locations are vulnerable to water penetration because different surfaces intersect here. There are many different types of roof flashings, but the seven below are the ones most commonly installed for homes: Cavity flashing – This is installed across the gap of a cavity wall, Apron flashing – This is flashing placed where the top of a sloped roof and vertical wall meet, Counter flashing – This is a piece of metal applied to the masonry wall that’s supposed to remove water off of the wall and direct it onto the surface of the roof, Step flashing – This protects the joints connecting the roof, dormer walls, and chimneys. It looks like stair steps up a wall or the side of a chimney, Valley flashing – This protects the valleys where two roof planes meet, Soaker flashing – This is either metal or plastic flashing wedged between a roof slope and an up-stand that is parallel with a rafter. As for materials, flashings can be made of colorbond, zincalume or copper. Consult a roofing professional first to determine which works best or is aesthetically and functionally suitable with your roofing material. Roof flashings are affordable, but if you’ll be installing them in many areas of your roof, you can get them for much cheaper and have them delivered right away when you shop online or order over the phone from a reputable roofing supplies vendor.
