How to Install Aluminum Roof Flashing
Roof flashing helps protect your roof from the elements, and aluminum roof flashing is a cost-effective style that will work as well as other types of flashing without costing you as much. This product is ideal for those parts of the roof that are connected to an extension, or where the addition meets the fabric of the older building. A kitchen or conservatory extension is the perfect candidate for this kind of installation, and aluminum roof flashing is a very basic fitting that you can install in a few hours. You may some friends to help you with fitting the flashing, one to hold the metal and the other to fix it to the roof, but you can do most of this project on your own.
Step 1 - Measure Out the Flashing
To get the best from your flashing, you will need to take the measurements of the roof, and then apply this to the complete pack of flashing pieces. While you are cutting the flashing down to size, you should also measure and cut it out using the tin snips or scissors. It is better to cut the flashing slightly too big while you are on the ground, and then use scissors to make the final fitting once you are on the roof. This will help to prevent you cutting off more than you end, and ending up with flashing which does not reach to the end of your roof.
Step 2 - Fit the Flashing
You should now take your flashing up and fit it to the side of the roof. Have your friend help you place the flashing on the roof, and then climb up to install it in place. Also install at the valley of the roof, where it joins up with other parts of the roof.
To get the best from the flashing, you should fit ½ of the sheet onto the side of the roof, and the other half onto the building or addition which it is touching. This helps to prevent water from sliding around the aluminum flashing and into the roof area.
Step 3 - Install the Flashing
Now you have the aluminum where you want it, have a friend hold it down. Begin to staple the edge of the sheet to the side of the roof. Aluminum is very soft, so take care not to press down too hard upon the metal, as this will dent and perhaps damage it. Continue to staple the flashing until it is securely in place, and tightly fitted against the side of the building and the roof.
