Whenever the roofers talk about the roof, the shingles get the most credit because it is visible to the eyes. However, this is not the case in actuality, many other parts of the roof deserve the credit and play the role in making the roof safe for the homeowners. Shingles are just a part of the roofing, and just like that Roof Flashing is another part of the roof.
What is Roof Flashing?
Roofing flashings is a thin layer of a metal sheet that is present on the roof and used for directing water to go away from the seams and joints from where the moisture could penetrate the roof. This can result in damaging the roof.
What is the purpose of Flashing on a roof?
Two parts of the roof are used for keeping the water away from getting underneath the shingles and those two parts are underlayment and roof flashings.
Flashing is an important part of the roof and it is that place where the roof meets a wall and the front side of the wall. Flashing is also present at the low points where the two slopes of the roof meet. It is present around the roof protrusions and edges.
Types of Roof Flashing
Most flashing roof materials are made up of copper, stainless or galvanized steel or aluminium. The flashing is used around the windows, doors, chimneys, gutters or any place of the roof or the structure of the house where the water can runoff. Some of the common types of roof flashing materials are as follow:
Base Flashing and Step Flashing
Base and Step flashings are used at such places where a vertical wall of the house intersects the surface of the roof deck. There are two such walls in the home; one is the front wall and the other one is the sidewall.
When the wind is blowing and it is raining, the water is blown against the wall of the home and the water would run down between the joints and this is why the flashing is needed there.
The base flashing plays the role at the joint and water is stopped before it gets between the wall and the shingles and then it is directed into the gutters.
Step flashings is present where the roof deck meets a sidewall. The pieces of this flashing are bent at an angle relative to the roof pitch and installed along the full length of the sidewall. This flashing is partially exposed and it is a little expensive than the normal flashing.
This flashing is placed in the places where the roof decks slope toward one another and this creates a low valley on the roof just like the mountains. The water flows into the valley just like a river and these flashing then make the water move away from the roof.
This flashing is visible from the ground and these are installed to overlap and form a gap that exposes the valley flashing. Usually, people choose an odd colour always to add contrast to their shingles.
This flashing is present in the places where the roof meets chimneys, vents, and dormers and other complicated places. This flashing comes with a unique set of materials and installation techniques to offers a water-tight seal service. Waterproofing these sides are always tough and every side requires a different kind of technique.
Drip Edge Flashing
This flashings directs the water at the edge of the roof so that it won’t penetrate under the roof and damage it along with the attic. This is the most important kind of flashing when used at the rake edges of the roof.
When the winds are strong, the shingles are most likely to lift along the rake edges and if they are wrapped with the flashing, it provides the shingles with extra safety.
