Why Roof Flashing is Indispensable
Roof flashing plays a pivotal role in safeguarding your home from the elements. It serves as a protective barrier at the joints and vulnerable points of your roof, ensuring that water is efficiently channeled away from these areas and into the gutters. The absence of proper flashing can lead to significant leaks, especially in areas that are exposed to substantial water flow, such as valleys between slopes.
The Evolution of Flashing Materials
Historically, the installation of flashing was a labor-intensive task. Before the advent of sheet metals, materials like birch bark were employed as flashing in some New England homes. With the introduction of sheet metal, the landscape of flashing underwent a transformation.
Lead, despite its associated health and environmental concerns, was one of the first materials used due to its remarkable durability. Copper, another durable metal, became a preferred choice for high-end constructions and historic homes. Today, a plethora of materials, including various alloys of steel, zinc, aluminum, rubber, and plastic, are used, each with its unique advantages and lifespan.
Key Areas Requiring Flashing
Valleys
Valleys, formed where two roof slopes converge, are critical areas that necessitate flashing. The confluence of the two slopes channels a significant amount of water into the valley, which, if not managed properly, can lead to leaks.
Chimneys
Chimneys, being one of the most prominent roof penetrations, require specialized flashing. The sides of the chimney employ step flashing to guide water away, while the area below the chimney uses an apron. Above the chimney, a cricket, resembling a small dormer, is installed to prevent water pooling.
Skylights and Dormers
Skylights, which bring natural light into homes, need a watertight seal with the roof. Typically, continuous sheet metal flashing is used alongside rubber gaskets. Dormers, on the other hand, have a unique structure. While they don’t form valleys, they still need sheet metal for the roof seam and step flashing for the walls.
Maintaining Your Roof’s Health with Home Evolution
It’s imperative to understand that roofing and flashing materials might age differently. For instance, while tile and slate roofs have a long lifespan, their flashing might need replacement sooner. Conversely, for roofs with materials like asphalt shingles, the flashing might last as long as the roof itself. At Home Evolution, we recommend inspecting asphalt shingle roofs every three years and tile or slate roofs every five to seven years. Our team ensures that not only your roof but also your flashing remains in optimal condition.
