Description: Roof penetrations can be categorized by whether the roof is sloped or flat. The preferred method of flashing penetrations through flat roofs involves the construction of a curb around the opening. Small penetrations often do not require curbs. With sloped roofs, the general approach is to attach the flashing before the roofing is installed. The shingles, slate or tile are placed over the flashing on the upper and two sides and slipped under the lower edge of the flashing.
