To install metal flashing to stucco, follow these steps:
1. Prepare the stucco surface by cleaning it thoroughly and removing any loose or damaged stucco.
2. Measure and cut the metal flashing to the desired length and shape using tin snips or a metal cutting tool.
3. Apply a layer of construction adhesive to the back of the metal flashing.
4. Press the metal flashing firmly against the stucco, making sure it is level and aligned with the desired location.
5. Secure the metal flashing in place by attaching it to the stucco using masonry screws or nails. Make sure to space the fasteners evenly.
6. Seal the edges and seams of the metal flashing using a waterproof sealant to prevent water infiltration.
By following these steps, you can successfully install metal flashing to stucco, providing a protective barrier against water and ensuring the longevity of your stucco surface.
If your home has stucco walls or a stucco roof and you want to enhance its water resistance, installing metal flashing can be a great solution. Made of aluminium or galvanized steel, flashing is a material used to prevent water from seeping through joints in your walls or roof. It is commonly found around chimneys, vents, and windows. While the installation process is relatively simple, it is important to prioritize safety measures before starting.
Essential Safety Tips
If you plan to install flashing on high walls or the roof, it is crucial to follow safety precautions. Ensure that your ladder is stable and secure, and have someone hold the base while you climb. This person should stay there to assist and keep an eye on your safety throughout the process.
Avoid working during or after rain, as wet surfaces can be slippery. It is also advisable to refrain from outdoor work, including flashing installation, during thunderstorms.
Important Considerations
If you are adding or replacing flashing on a roof, remove any shingles in the area where you intend to install the new metal material. In the case of stucco, there may not be any shingles to remove. Some experts suggest cutting out sections of stucco, inserting the flashing, and then replacing the stucco. However, this method may result in an inconsistent appearance and may not always be effective. Alternatively, you can directly attach the flashing onto the existing stucco and stucco around it, effectively sealing it.
When purchasing metal flashing, consider the size and shape needed to cover the desired area. Take measurements and use them to guide your purchase. Additionally, gather roofing felt, asphalt cement, caulk, nails, and a hammer for the installation process.
Installation Process for Stucco Roof Flashing
If you are working on the roof, start by covering the area where the flashing will be installed with roofing felt. Overlap the new felt with the existing felt by one foot and secure it with nails. Apply a layer of asphalt cement to the area where the flashing will be attached. Before the cement dries completely, place the flashing and press it firmly into the cement. Use nails or screws, depending on the ease of piercing the existing stucco, to secure the flashing in place.
If you are installing step flashing, where one piece of flashing overlaps the previous one in a staggered pattern, apply additional cement and attach the next piece of flashing in the same manner. Once the flashing is fully installed, seal the edges with caulk or additional stucco to prevent water infiltration into the roof.
