At Sunshine Coast Roofers, we take pride in our expertise in roof repair and metal roofing. One crucial aspect of roofing systems that homeowners need to familiarise themselves with is metal roof flashings. In this comprehensive guide, we will delve into the world of metal roof flashings, their types, components, and their importance in maintaining a watertight roof.
Types of Metal Roof Flashings
There are various types of metal roof flashings available, each designed for specific areas of the roof. Let’s explore some of the most commonly used types:
Drip Edge Flashing
Drip edge flashing is installed along the eaves and rakes of the roof. Its primary function is to redirect water away from the fascia and into the gutters, preventing water from seeping into the underlying roofing structure. Drip edge flashing also covers the gap between the roof deck and fascia board, preventing the entry of pests into your home.
Valley flashing is used in areas where two roof slopes meet to form a valley. Its purpose is to channel water away from the valley, preventing water pooling and potential leaks. Valley flashing can be made of various metals such as aluminium, stainless steel, or copper, and its shape can
Step flashing is commonly used at intersections between the roofing material and vertical structures like walls or chimneys. It consists of individual pieces of metal flashing layered on top of each other to create a barrier that directs water away from the roof. Step flashing is crucial in preventing water infiltration at these vulnerable areas.
Counter flashing is used at places where the roof meets a vertical wall, such as a chimney. It consists of two layers: the base flashing, which is fixed at the bottom, and the counter flashing, which is inserted into a groove cut into the wall. Counter flashing diverts water that drips off the wall onto the roof, preventing water leakage at the wall-roof joints.
Skylight flashing is specifically designed to protect the areas around skylight frames from water infiltration and debris accumulation. Proper installation of skylight flashing is crucial for ensuring a watertight seal between the skylight and the roof.
In addition to the aforementioned flashings, there are various other types of metal roof flashings available, including chimney flashing, headwall flashing (also known as apron flashing), and gutter apron flashing.
Components of Metal Roof Flashings
Metal roof flashings consist of several components that work together to create a watertight seal, following the standards set by the government. Some of the key components include:
Drip caps are L-shaped metal pieces installed above windows, doors, and other openings to prevent water from seeping into the underlying structure. They divert water away from vulnerable areas, ensuring a dry and secure environment.
Counter flashings are installed over step flashings, covering the top and preventing water from running behind the flashing. They play a vital role in preventing leaks and directing water away from the roof.
Valley liners are metal strips installed in the valleys of the roof to channel water away from the area. They provide an additional layer of protection against water infiltration and potential leaks.
Gutter aprons are installed along the edge of the roof where the roof meets the gutter. They prevent water from draining onto other building components and guide it into the gutters, protecting the roof from weather damage.
Importance for Roofing Systems
Metal roof flashings are an integral part of roofing systems and play a crucial role in maintaining the integrity of the roof. By effectively sealing intersections and directing water away from vulnerable areas, metal roof flashings prevent leaks and water damage. They contribute to the longevity and performance of the entire roofing system, ensuring a dry and secure environment for your home.
