Quick Answer
DIY flashing installation is feasible for homeowners with basic roofing knowledge and physical capabilities, but may not be suitable for those with complex rooflines or multiple skylights.
Assessing Your Roof’s Complexity
Before attempting a DIY flashing installation, assess your roof’s complexity. If you have multiple skylights, valleys, or complex curves, it’s best to consult a professional roofer. However, if your roof is relatively simple, you can proceed with caution. A good rule of thumb is to have at least a basic understanding of roofing terminology, such as “hip”, “valley”, and “ridge”.
Choosing the Right Flashing Materials
To ensure a watertight seal, choose high-quality flashing materials that are compatible with your roofing type. For example, for asphalt shingle roofs, use EPDM (ethylene propylene diene monomer) or PVC (polyvinyl chloride) flashing. For metal roofs, use a specialized metal flashing material. When selecting flashing, consider the following factors: durability, UV resistance, and ease of installation. A good flashing should withstand at least 20 years of exposure to the elements.
Installing Flashing around Solar Panels
When installing flashing around solar panels, follow these steps: (1) measure and cut the flashing material to fit around the solar panel; (2) apply a bead of roofing cement to the back of the flashing and press it into place; (3) secure the flashing with roofing nails or screws; and (4) seal any gaps with additional roofing cement. Be sure to follow the manufacturer’s instructions for specific flashing materials and solar panel mounting systems. A well-installed flashing system can ensure a watertight seal and prevent costly water damage.
