Some areas of your roof are more prone to leaks compared to other parts. It’s for this reason that these areas, including roof valleys and skylight perimeters, need to be fitted with roof flashing. In this post, your residential roof replacement company, Hometown Contractors Roofing, explains the basics of roof flashing.
Flashing is a material you put over the joints on your roof to prevent any water from seeping into your home. Flashing is typically made of impervious material, such as plastic, roofing felt and rubber. However, the most common flashing material is made of a variety of metals. These rust-resistant metals are usually copper, galvanized steel or aluminum.
Galvanized steel is the most commonly used among the metal flashing materials. Aluminum, on the other hand, is preferred by homeowners who like DIY home roof repairs due to its malleability. Copper flashing is typically custom-made for copper roofs.
Main Types of Roof Flashing
Flashing is classified according to the purpose it serves. Here are the main types of roof flashing:
This type can be found around the base of a chimney. It consists of different types like continuous and step flashing to prevent water from seeping into the edges.
Continuous flashing is applied to the joints between a vertical wall and a sloped roof.
Step flashing consists of right-angled metal pieces that are applied to the areas where the roof, dormer side walls and skylights meet.
This W-shaped flashing is fitted over the valley where two roof planes meet. It is placed over the roof felt before the installing the roof’s finishing material.
Vent Pipe Flashing
As the name suggests, vent pipe flashing is applied to pipes and flues. It is cone-shaped and has a flange at the base.
These are applied along the eaves and rakes of your roof.
