Roof flashing is a material used to keep water off critical areas of the roof. Flashing is typically made of galvanized metal or iron, but other materials can also be used to keep your roof safe, free from water and other environmental elements. Flashing is installed to surround roof features such as vents and chimneys. Flashing redirects water to the outer part of the roof instead of letting it get inside of the roof deck. Many people and even some contractors ignore the importance of flashing a roof, this unfortunately leads to poor installation and future problems such as leaking. For flashing to work properly it must first be installed correctly. In this article, we will explain how to properly install roof flashing.
Where to install roof flashing?
As a protectant, flashing is placed anywhere where the roof needs protection from external elements. These include any intersections or joints which are usually around chimneys, vents, and skylights. If you currently have a leak, then you need to look around those specific areas, to make sure that the flashing materials are in good shape and placed correctly. Any weak areas that can come in contact with water need to be flashed.

Installation is not easy and requires several tools, so if you have any doubts or you’d rather leave this job to a professional roofing company you can call us at Paramount roofing.

The first step to install roof flashing is preparation for a traditional technique that requires cutting the lower part of the surface with a saw in order to bend the metal there and then the surface will require sealing.
Step 1. Prepare the surface and get adequate materials.
You need to clean the working surface of old cement or adhesives. Once that you have cleaned the surface, you will need to get the materials. You can visit popular hardware stores such as The Home Depot®, Lowes®, or any local or preferred hardware store. Look for the kind of flashing that fits your working surface and get any needed tools to cut the materials.
Step 2. Measure the metal and mark the surface
Use your tape measure to measure your piece of metal. You want to make sure you know where you will need to bend the metal to tuck in inside the surface. The recommended length of metal to go inside the surface is 1/2 an inch to an inch. Since this process requires bending and fitting metal, you will need to mark your metal to bend at the 1/2 (or a whole) inch length inside the hole and match the measurement on the working surface.
Step 3. Mark where you are going to cut
You can use a chalk line to mark where you are going to cut, so you have a straight line to follow when cutting with the saw.
Step 4. Use a SkilSaw to cut the surface
Use a saw to cut the surface that the metal will go through. Use the appropriate tools, do not use a wood, another kind of saw or tool that is not designed for the surface you are working with.
Step 5. Bend your flashing
Using a metal bender, or another method to bend the metal that will go inside the surface.
Step 6. Install the flashing into the wall
Install the flashing onto the working surface.
Step 7. Seal the flashing to the wall and the roof.
Take a tube of flashing sealant or any other kind of sealant to cover and seal the exposed surface.
