- 3. Flashing refers tothin pieces of impervious material installed to prevent the passage of water into a structure from a joint, or as part of a weather-resistant barrier (WRB) system. Before the availability of sheet products for flashing, carpenters used creative methods to minimize water penetration: • Angling roof shingles away from the joint • Placing chimneys at the ridge • Building steps into the sides of chimneys to throw off water. The introduction of manufactured flashing decreased water penetration at obstacles such as windows, doors, chimneys, vents or pipes thus making buildings more durable and reducing indoor mold problems. Purpose of Flashing
- 4. Flashing types arenamed by their location of uses or shapes: • Wall flashing may be embedded in a wall to direct water that has penetrated the wall back outside. • Sill flashing - A concealed flashing placed under windows or door thresholds to prevent water from entering a wall at those points. • Through wall flashing - Spans the thickness of the wall and directs water to weep holes • Cap flashing (drip cap) - Often used above windows and doors • Drip edge – A metal used at the edges of a roof • Step flashing – Pieces of flashing material which overlap each other in "steps" • Counter flashing – Covers a base flashing • Valley flashing – In the valley of two intersecting roof planes • Roof flashing is placed around objects which protrude from the roof of a building to deflect water away from seams or joints and in valleys where the runoff is concentrated. A structure incorporating flashing has to be carefully engineered and constructed so that water is directed away from the structure and not inside. Flashing, improperly installed, can direct water into a building and lead to rot, mould and other undesirable issues. Common Types Of Flashing
