When homeowners are trying to prevent future roof leaks from occurring, many are focused on the shingles themselves. However, the roof flashing is a major component that can prevent leaks. There are several places on the roof where flashing may be found, including along the roof eaves, around roof penetrations and in other areas of the roof that may be more susceptible to water damage. If homeowners notice during a routine roof inspection that they do not have flashing in these areas, they should contact their local Bergen County roofing contractor for help.

The job of the roof eaves is to divert water into the gutter system when it rains. However, there are some cases where the gutters may become blocked. This can cause the water to seep back up underneath the shingles attached to the roof eaves. Over time, this can cause the roof deck to become rotten. If enough damage occurs, dry rot can affect the wooden components of the roof. To avoid this, flashing known as a drip edge can be installed along the edges of the roof to keep water out.

Certain areas of the roof, including the valleys, are more susceptible to water damage due to the roof design. Water tends to collect in the roof valleys before it is directed to the gutter system.

The roofing experts at All Professional Remodeling of Bergen County NJ can assist you with any questions regarding roofing, windows or skylights.

The more water that collects there, the more likely it is that water damage will occur. This area can be additionally susceptible because there is going to be a narrow space in the valleys that is not fully covered by the shingles. Metal flashing can help direct water where it needs to go.

Roof penetrations can include duct work, chimneys and skylights. When these roof penetrations are installed in the roof, the roofing shingles or tiles do not necessarily butt up against the skylight or chimney, resulting in spaces where moisture can get through and damage the insulation and roof deck. To avoid this, flashing is usually installed around these penetrations. Additionally, counter flashing may also be added as another layer of protection against roof damage and leaks.

When a roof has adequate flashing, not only will the shingles last longer but the home will be better protected against future leaks and other major damages that can be caused by water penetration. If homeowners notice that a leak has occurred, there could be a problem with the flashing, and an expert roofer should be contacted to repair it.
