A Quick Guide to Trim & Flashing Options for Metal Roofs

When installing a metal roof, you need to choose the material you use, as well as the trim that goes around the edge and completes the look. Here's a guide for choosing trim and flashing options. 

Styles of Roof Trim

There are multiple different styles and types of roof trim that you can use on your metal structure. It is important to be aware of all your options because the type of roof trim that you use really depends upon the structure of your roof and your home.

  • Valley Trim: Valley trim is a type of metal trim that is used when you are joining two different parts of a roof together. Valley trim helps to direct rain and snow off the roof in the proper place.
  • Transition Flashing: Transition flashing is used when you have two different areas on your roof that are two different pitches. This is commonly used on homes that have a gable that sticks out homes that feature roofs that are lower in one area and higher in another.
  • Endwell Flashing: Endwall flashing is another type of metal trim. It is generally used to protect protrusions. For example, if you have a chimney, a lean-to, or a dormer, you will want to use endwall flashing.
  • Gable Trim: Gable trim is designed to be used at the end of your metal panels. Gable trims help to bring your panels together and give the edges of your roof a more uniform look. This type of trim is most visible in areas where there are no gutters in place.
  • Eave Trim: Eave trim is used instead of gable trim in locations where you will have a fascia board that needs to be installed. Eave trim is used to cover up the fascia board and create a more consistent feel.

Considerations When Selecting Roof Trim

When it comes to selecting the best roof trim, there are a few different factors that come into play.

  • Roof Style: The style of your roof plays a large role in the roof trim and flashing that is used. For example, a roof that is the same pitch wouldn't need to use any transition flashing.
  • Gutters: If you add gutters, you are going to have to use a special type of trim on the eaves that will allow for the gutters to be hung up. You need to know before putting your roof in place if you want to install gutters.
  • Curb Appeal: Finally, the curb appeal and look that you want will determine the type of trim you use, especially around the outer edge. Different styles and colors will impact the way your roof looks from the ground.

When choosing the trim to use with your metal roof, consider your budget and the style and appearance you want your roof to have. Talk to your roofing contractor and get their advice on the best trim for your metal roof.
