Flashing is a process where a thin sheet of material is used to prevent water from seeping into a building. The process is done in areas such as skylights, chimneys, and vents with a seal. Flashing helps to prevent leaks and moisture from getting into your home. If flashing is not properly installed, it can lead to the deterioration of roof joints. Call WNY Company at (716) 776-7663 to have your flashing properly installed.
