Clinton Township MI Roof Maintenance: All About Roof Flashing Repair

An asphalt shingle or tile roof usually works like this: You pile these roofing materials together and overlap them by half or a third to achieve a leakless roofing system that is cool, durable, and reliable. However, does it guarantee a leakless system if you have chimneys, vents, and skylights? Flashing is the roof part that prevents roof leaks, which makes roof flashing all the more important.

However, you'd definitely want to know what is roof flashing and how it functions. Jamar Roofing and Sheet Metal has a great answer for these two questions below.

Roof Flashing Repair: What is Roof Flashing

Typically, flashing consists of strips of galvanized steel or aluminum. Roofing companies apply it to provide extra protection around places where roof surfaces join together, for example along the tops of dormers and roof joints. Flashing will also frequently help waterproof locations where the roof opens to accept other structures; such as chimneys, skylights or elevated vents. Flashing performs an important role in roofing systems. It safeguards edges where leaks frequently cause significant damage.

Today, some manufacturers even offer specialized styles of flashing for specific areas of a rooftop. For instance, some skylights also produce specific flashing for their products. Similarly, uniquely pre-formed metal flashing may help protect vent pipes, eaves and other structures on the roof. Roofing system designers frequently include flashing in their plans. (Continued)

Now that you know flashing is a type of sheet metal, you can make sense how it works to prevent roof leaks. With its protective seal over residential and building joints, it creates a water and weatherproof barrier. However, it isn't infallible; flashing can wear down over time, and you'll need to perform roof flashing repair where needed.

In addition, you'll have to be familiar with the different types of roof flashing to use for any home or building. Do It Yourself has a great listicle on all types of materials you'll need for a proper roof flashing repair.

Different Types of Roof Flashing for Homes

1. Roof Flashing

Roof flashing can be used internally, which means that it is installed under the actual roof shingles. There is also an external type of roof flashing that is laid on top of the shingles in valleys and along peaks. This flashing can be made of metal or some sort of waterproof membrane. It is applied in several different areas.

2. Window Flashing

Window flashing is installed around a window to keep rain from leaking in around the sash. Wind-driven rain can easily enter into small openings in the home around joints or crevices, but weatherproof flashing will help protect the areas around your windows. There are generally three types of window flashing:

  • Sheet metal - This is the basic thin sheet of metal that can be easily bent and molded to fit a space.
  • Vinyl - This is the type of flashing that usually comes with vinyl siding.
  • Tape - This is the newest form of flashing and comes as a self-adhering flexible membrane. (Continued)

How to Install Step Flashing With a Wall Corner

If a wall corner is on the rooftop, you will need to create a corner flashing piece using a typical step flashing piece. These instructions will tell you how to create a corner piece and how to install step flashing generally:

  • Step One: Install your underlayment completely and your shingles up to where the wall begins, so that the first piece of flashing, or the corner flashing, will rest on a shingle.
  • Step Two: To make corner flashing, take your tin snips and cut a 45-degree line from an outside corner to the center fold. Then, cut along the center fold and remove the resulting triangle. This will allow you to bend the step flashing around the corner cleanly. If you do not wish to form your own corner flashing, you can buy pre-bent pieces and cut them to size, or use a piece of corrugated aluminum, which is easier to bend. (Continued)
