In this article, we gathered some of the most important information about roof flashing and its importance in roofing maintenance. These facts will help you keep your roofing in optimal condition, thus protecting your home and loved ones.
Flashing plays a huge role in your entire roofing system. Usually made from copper, sheet metal, or aluminum, roof flashing seals the roof joints, preventing leaks from your roof by keeping the water out. The type of flashing installed depends on the roofing material that is used.
Most homeowners who opt in DIY roof flashing usually choose aluminum as they are more affordable and easier to install. But regardless of the material, roof flashing is built through soldering.
Areas that need Roof Flashing the most
Some parts of the roof are more vulnerable to water leaks than the other parts. Installing flashing in these parts can provide an extra layer of protection. Among these areas are:
Roof surface of dormer walls
Aside from the mentioned above, you would know that a specific part of your roof needs flashing if it has two surfaces connecting together, which is likely to receive more water during rainfall.
Types of Roof Flashing
The type of roof flashing you need depends significantly on the type and design of your roofing. Every roof flashing is unique in each home and each part of the roof. But what are the areas that generally need flashing?
Chimney and chimney caps
The chimney is the area where most flashing is necessary. Flashing is usually present at the chimney’s bottom, step flashing on the sides, and saddle flashing for the top. Cap flashing, on the other hand, hangs over the edges of the flashings and acts as an extra layer of protection against water leaks.
This is the most common flashing type for homes with vertical walls and sloped roofs. Drip edges are also a feature that helps in preventing water seepage near the roof eaves.
This type of flashing is usually installed together with steps flashing if there are skylights on sloped roofing.
Saddle flashing is usually installed in railing attachments, joints, beams, and other areas where a parapet wall intersect with other walls.
Valley flashing is installed to protect the valleys on areas where two roof planes meet together. This W-shaped flashing is installed at the top-side of the building felt before the installation of the roof finishing.
It is a cone-shaped flashing with a base flange that fits on the shingles. This is installed over the roof pipes and flues.
Areas where most leaks can be found
The valleys and locations where pipe penetrates the roof surface are the areas on the roofing system that are at the highest risk for leaks. Aside from ensuring that pipes have proper vent pipe flashing, sealing these areas with an asphalt roofing cement to keep the water out can usually solve this problem.
Keeping all your roof flashing in its best condition all the time is necessary to prevent leaks, which can lead to more severe problems. Leaving your flashing without maintenance for so long would end up posing your home to risks, as it will not be able to perform their job in keeping your home safe and dry throughout the seasons.
