Metal flashing is an important element of a roofing system. The main types of metal flashing that you need to know when purchasing a roof are drip edge, wall and chimney flashings.
The standard drip edge contains aluminum. It has a 3-inch top face which is installed 2½-inch up the roof’s slope and extends ½-inch over the line of the roof as well as 1½-inch downwards towards the eaves.
The importance of drip edge include the following:
• It protects the transition from the line of the roof to the fascia board.
• It supports the overhanging shingle edge.
• It gives room for the adequate run-off of water into the trough.
• It also gives a nice finishing to the appearance of the roof.
Wall and Chimney Flashings
They protect the transition from the roofs the walls which penetrate the deck. Roofing contractors often quote the cheapest price when it comes to flashing a wall to make their price attractive. Being knowledgeable in this area will help you make the right choice for your home.
Stepped flashings require an advanced level of workmanship to execute. They are costlier than straight flashings. Straight flashings are sealed to the sidewall through the use of a caulking.
The best way to offer protection to the sidewalls is through grouting flashings into walls and chimneys. The sidewalls can be finished by sealing the flashings with the aid of caulking. This helps the water travelling down the walls to catch the flashing and then get carried down the roof.
