Frequently Asked Questions (FAQs)

1. What type of flashing do you use on windows?

There are three main types of window flashing: tape, sheet metal, and vinyl. Tape window flashing is commonly used as a self-adhering membrane in new construction and renovations. It is easy to use, flexible, and durable.

2. Does flashing go over or under shingles?

Flashing should overlap the roof-covering material. However, on asphalt shingle roofs, the part of the headwall flashing that extends over the shingles is often covered with a course of shingle tabs for aesthetic purposes.

3. Do you need flashing around a window?

Yes, it is important to use flashing around all types of windows, whether new or existing. Window flashing should be used when the exterior is exposed to weather elements or other external sources like soil erosion or poor drainage systems. It is a crucial component of any construction or renovation project involving windows.

4. How important is window flashing?

Window flashing is essential for proper window installation. It provides an extra barrier between your window and siding, protecting your home from rain and moisture. Siding alone is not enough to prevent water damage, which is why window flashing is crucial.

5. What are two types of flashing?

There are two main types of flashing: continuous flashing and step flashing. Continuous flashing is used to provide waterproofing where the roof meets a vertical wall. Step flashing, on the other hand, is often preferred for roof-to-side-wall flashing installations.

6. Should roof flashing be exposed?

Roof flashing should be partially exposed along the wall. Some homeowners choose more expensive materials like copper for flashing to achieve a specific aesthetic as step flashing is visible.
