How to Repair Flashing on a Roof
You can imagine how many different types of roof flashing are available on the market today. Here at ROOFMASTERS, we know that no roof is the same, and we firmly believe our customers should too. Below you will find the 8 common types of roof flashing:
- Continuous Flashing
Also known as “apron flashing”. This term was given due to the fact that this type of flashing does in fact resemble an apron. Long, single pieces of metal that are meant to carry water to shingles beneath. However, this type of flashing is not often recommended due to the inflexibility of the material. Over time your home will expand and contract with changing temperatures. When left without continuous upkeep often this flashing can break or distort, which will lead to water getting inside the soft spot in your roof. If using continuous flashing, it’s important to have long pieces with built-in expansion joints to assist your flashing with the expansion of your home during changing seasons.
- Base Flashing
Often, base flashing is used on the bottom part of your chimney. This is because this area will often require two pieces of flashing to be installed. When using base flashing, the main purpose is to make sure that rain and weather don’t have a chance to sit around that area, and are directed downward on the roof. Another largely popular benefit of installing base flashing is that due to the two pieces of material, your flashing has the ability to expand with your home.
This form of flashing is placed on the opposite to the base flashing, and or above the base flashing.
- Step Flashing
Step flashing is a rectangular piece of flashing that is bent at a 90 degree angle in the center. This flashing is usually placed in layers with shingles to ensure water flows away from your wall.
- Skylight Flashing
When purchasing a skylight, most manufacturers will include flashing in their products, however sometimes they do not. When this happens, it’s important to call a professional to create or install it separately and correctly.
- Valley Flashing
As stated above the “roof valley” is a highly susceptible area to roofing damages. Open valleys will have metal flashing placed in order to protect this area in the roof further. Installing valley flashing is likely to increase the livelihood of your roof overall.
- Drip Edges
Drip edges are thin metal pieces of roofing flashing that are placed on your roofs edging. These drip edges do exactly as they say with their sole purpose being to help water drip off of your roof, with ease, and no to minimal damages.
- Kickout Flashing
Last but not least, kickout flashing. Kickout flashing is a type of flashing that is made to build the gaps between step flashing and your gutters. The sole purpose of this is to help direct water flow away from the wall and instead, into your gutter system.
