When it comes to roofing, proper installation techniques can make all the difference in ensuring a durable and effective system. One of the leading alternatives to traditional lead for valley detailing is Wakaflex, a versatile and lightweight material designed for ease of use. In this comprehensive guide, we will walk through the step-by-step process of installing Wakaflex rapid flashing for valley replacement, ensuring that your roofing project is executed flawlessly.
Understanding Wakaflex
Wakaflex is a butyl rubber-based material that incorporates a wire mesh, providing both strength and flexibility. It is designed to replace traditional lead flashing, offering several advantageous features such as reduced weight, ease of handling, and minimal waste during installation. Unlike lead, which is typically limited to 1.5-meter lengths, Wakaflex can be applied in lengths of up to 2.5 meters, which significantly reduces the number of laps required.
Preparation for Installation
Before installation begins, ensure you have selected a proper setting with all necessary tools and materials on hand. The areas around the valley should be prepared with boards and battens already installed. A valley detail typically requires a width of 100mm, allowing for 50mm of tiles to overhang on either side of the valley.
-
Gather Tools and Materials: You will need corresponding fastening materials, a pair of scissors or snips for cutting the Wakaflex, gloves, and a hammer for tacking the flashing down.
-
Layout: Position the Wakaflex over the valley, ensuring it overlies the boards evenly.
Installing Wakaflex Rapid Flashing
Now, let’s go through the steps of the installation process:
-
Cutting the Material: Measure the required length of Wakaflex to fit the valley and cut it using scissors or snips. The cut should extend past the ends of the valley slightly to allow for proper trimming later.
-
Positioning the Wakaflex: Lay the Wakaflex into the valley detail, ensuring it reaches the bottom where it will later feed into the gutter. At this stage, it is crucial to ensure that the seamless aspect of the installation allows water to flow smoothly without resistance.
-
Securing the Flashing: Tack the Wakaflex into place on the battens or boards using nails or fasteners. This will help hold the flashing steady while you continue to mold and shape it into the valley.
-
Removing the Backing: Carefully peel back the perforated backing of the Wakaflex on either side, allowing you to secure the material further without it sticking down to the underlying roof.
-
Create the Welt: As you move upward in the valley, you must create a welt with the Wakaflex. This involves folding the material back over to create a waterproof barrier, preventing any potential runoff from seeping out sideways.
-
Tacking the Material: Continue tacking the sides of the Wakaflex to ensure it holds firmly in position. Care should be taken to leave enough material loose to achieve the required welt.
-
Finishing the Detail: Once the Wakaflex is securely in place, install the surrounding tiles with a 50mm overhang that extends into the valley, effectively covering the flashing and directing any rainwater into the gutter.
Benefits of Using Wakaflex
One of the primary advantages of Wakaflex is its ease of use. The material can be manipulated to fit various shapes without the need for elaborate tools or techniques typically associated with lead flashing. Moreover, Wakaflex chemically bonds with itself when overlaps occur; this creates a seamless installation that obviates the need for additional adhesives or clips.
Final Considerations
Always prioritize safety during the installation process. Using protective gear such as gloves when handling the material helps safeguard against injuries.
Keep in mind that thorough planning and careful execution during installation will pay off in terms of both longevity and performance of the roofing system. By following these steps for installing Wakaflex, you can ensure a reliable and efficient roofing detail that stands the test of time.
In conclusion, Wakaflex is an innovative solution for valley replacements that combine flexibility, ease of use, and effective water management. With this step-by-step guide, you now have the knowledge to master the art of installation and enhance the integrity of your roofing project.
