Roof flashings are an essential component of any roofing system. They are used to prevent water from seeping into the roof through gaps and joints, ensuring that the building remains dry and free of leaks. Flashings are typically made from metal, such as aluminum or copper, and are designed to fit snugly around pipes, vents, chimneys, and other protrusions on the roof. They come in a variety of shapes and sizes to accommodate different types of roofing materials and are installed using a combination of adhesives and fasteners. Properly installed flashings can help extend the life of a roof and prevent costly water damage to the building's interior.

Frequently Asked Questions (FAQs)
1. Does flashing go under shingles?
Flashing should overlap the roof-covering material, but on asphalt shingle roofs, it is often covered with a course of shingle tabs for aesthetic reasons. This ensures that the flashing is properly integrated with the shingles, providing a secure and watertight seal.
2. Is roof flashing necessary?
Yes, roof flashing is essential for a quality roof. It is a crucial component that helps protect your home from the elements. Properly installed flashing prevents water from seeping into vulnerable areas, such as joints, intersections, and roof penetrations, reducing the risk of leaks and potential water damage.
3. Should roof flashing be exposed?
When it comes to the wall, the flashing should be partially exposed. Some homeowners opt for more expensive materials like copper for aesthetic purposes, as the step flashing can be visible. This allows for a visually appealing finish while still providing the necessary protection against water intrusion.
4. What happens if you don't have roof flashing?
Without proper roof flashing, your roof would be prone to constant leaks, leading to significant damage to your home. Water would penetrate vulnerable areas, causing structural issues, mold growth, and other water-related problems. It is crucial to have professional roofers install flashing correctly to ensure the integrity of your roof and protect your home.
