Flashing is an incredibly important component when it comes to roofs. When installed underneath the shingles, it can help direct water away from weaker points in the roof. If a new roof is being installed, a professional Denver roofing contractor can ensure that flashing is installed in the proper places.

Many roofs have valleys which occur where two roof planes intersect with each other. It can be very difficult to shingle this area properly. If the roof is made of asphalt, a strip of galvanized steel can be installed along the joint to ensure that the water can flow down the roof. The shingles are then interlaced over the flashing.

Flashing is also needed where the roof meets a vertical wall. This may include dormers and chimneys. Vertical wall flashing should be installed in these areas to help form a seal so that water cannot seep through. It is also likely that counter flashing will need to be installed as well. In some cases, it can be difficult to remove the old flashing from masonry; however, new flashing is important when it comes to preventing leaks.

Like valley flashing and vertical wall flashing, drip edge flashing is commonly found on many homes. There are two types of drip edge flashing: flashing for the gutter edge and flashing for the roof rake edge. When attached to both edges, the drip edge flashing helps to direct water away from the fascia. This flashing, which comes in 10 foot strips, is usually installed before the roofing felt is attached.

There are several other types of flashing that may also be used on certain types of buildings. For example, penetration flashing may be used around plumbing vent pipes that extend through the outer roofing materials. The flashing helps to provide a seal. Additionally, decorative guttering may be left on the building if it adds to the home's curb appeal. Because the decorative guttering attaches to the drip edge, it may be difficult to remove old drip edge flashing. In these cases, a new gutter apron can be used as an overlay for the flashing.

A particular roof may not have every type of flashing installed. The type of flashing that may be included depends on the roof's design. Additionally, the flashing that can be installed comes in a number of different metals. It is recommended that an experienced roofer assist when new flashing needs to be installed.
