Step-by-Step Guide for Installing Step Flashing On Your Roof

Installing step flashing can seem like an intimidating task, but with the right tools and instructions, anyone can complete the job with an attractive result. Step flashing installation is important to ensure a well sealed roof and prevent any water damage. Step flashing should be installed in all the outside corners of the roof and along the edges. Moreover, materials needed for the installation include felt underlayment, galvanized step flashing, aluminum kickout flashing, shingles, roofing nails and a hammer. By following the correct steps, installing step flashing is quite easy.

Before installing step flashing, it is essential to prepare the roof by laying out a felt underlayment. Felt rolls should overlap each other by three inches and be firmly secured using staples. After this, a metal trim is attached to the edges and corners of the roof, using roofing nails. For roofing corners, “drip-edge” is used and for sides of the roof, rake-edges can be used.

A starter row of step flashing is then installed in accordance with package instructions. A tab should be cut off before the installation of the full shingle layers which should start from the roof’s outside corner. After this, the layers should go back half-tab for the next row of shingles. For the last step, a kickout flashing is installed with the edges going beyond the drip edge around 1 1/2”.

It is highly recommended to read the instructions carefully before beginning the installation. There are some product manufacturers that provide images and instruction manuals to guide the user during the installation. For tools and materials that are rarely used, it is possible to rent them from a local hardware store.

Installing step flashing can result in a secure and perfected roof and save a lot of money. And, if done correctly following all safety precautions, the installation process can be an educational and rewarding experience.
