All about Roof Flashing

Jacksonville roof flashingAt A.J. Wells Roofing Contractors, we work to fulfill all of your home’s flashing needs. You might wonder what is flashing and does your home need new flashing. Flashing is usually made of galvanized steel or aluminum, but can be made from a variety of materials such as rubberized asphalt, plastic, copper, stainless steel or butyl rubber. The flashing is placed over joints in the ceiling and roof to prevent water from seeping into your home’s structure. It is also placed above windows. Flashing helps to direct water away from the home’s structure.

When properly installed and working, flashing quickly diverts rain water from even the most extreme storm. Even a new home may suffer from flashing problems if the material was improperly used during the home’s construction. It is critical that your home have good flashing or mold and mildew will build up in the home’s wood, insulation and drywall from seeping water. Ongoing moisture will eventually cause your home’s structure to rot and become compromised.

Regular Maintenance is Necessary

You should regularly inspect the condition of your roof’s flashing to make sure it is not cracked, oxidized or deteriorated. Flashing may also become loosened during a severe wind storm or ripped completely from the home. After all severe wind storms, hurricanes or tornadoes it is advised that you have your home’s flashing inspected. Look along the valleys in your roof’s surface, around any chimneys, pipes, skylights and the home’s dormers. If your flashing looks bad you may want to call a roofing contractor in Jacksonville to get their professional opinion. Often only one area of the flashing will suffer damage or need replacement. The roofer will cut away the area of old or damaged flashing and install new material. A roofer can cut and shape a piece of sheet metal to install in any areas of damage. The new piece will be adhered to the roof’s surface using caulking or roofing cement.

Here are areas of home’s flashing that should be inspected for possible replacement. A roofing contractor in Jacksonville would be happy to look over your home’s trouble spots to give you an idea of how effective your flashing is.

  • Dormer — Dormer windows usually have metal flashing. Small squares of flashing will be inserted between the roofing. It is also sometimes installed as a strip. It will extend like a front apron on a dormer window.
  • Skylights — Flashing around skylights is made up of one large piece. It should be an 8 inch vertical run of material. In order to replace flashing around a skylight, the skylight usually needs to be removed to gain access to flashing.
  • Chimney — At the base of your chimney you will see flashing. They flashing is usually bent and the shingles will overlap it. The chimney’s cap may also be over the ridge of the flashing.
  • Pipe Stack –Flashing around a pipe stack should be slid over the pipe and extend four inches below the pipe and eight inches above the pipe.
  • Hood Vent — The flashing around a hood vent should extend under the shingles above the vent and over the shingles below the vent.
