Roofs are vital components of buildings, and they must be protected from water that can damage them in order to last longer. This guide covers all you need to know on what galvanized steel flashing entails, importance of same, types of such flashes as well as methods employed when installing them. Thus, if you are a homeowner planning a new roof or upgrading an old one, this article will provide you with all the necessary information about Roofing.
What is Galvanized Steel Flashing?
Galvanized steel flashing, also known as galvanized metal flashing, consists of a steel material that has been coated with a layer of zinc. This coat of zinc resists rusting and corrosion and makes the material well suited for safeguarding roof edges, valleys, chimneys and other points susceptible to water leakage. Most often used as roofing materials in both business premises and residential dwellings are galvanized steel flashings.
Galvanized Steel Flashing Details
Galvanized steel flashing is one of the essential parts of the roof that prevents water infiltration in the most exposed points. It is produced through hot-dip galvanization where steel is coated with zinc in order to allow the material to be very resistant to rust and corrosion. It enhances the life span of steel and offers excellent weather protection throughout the year. These flashings are usually in shapes, customized designs, rolls, or sheets and are highly considered for valleys, edges, and chimneys because of the strength and flexibility of the galvanized steel, therefore making it common in residential and commercial buildings roofing.
Key Features:
- The zinc covering offers a strong barrier to rust.
- There are sheets, rolls or custom designs which are available for various uses.
- These roofs endure adverse environmental conditions hence they add years to its life span.
- Can be used anywhere on the roof such as valleys, edges or around chimneys
- It provides great protection at a low price compared to other metal flashings such as copper
How to Measure Galvanized Steel Flashing?
This is important to ensure that the galvanized steel flashing sits perfectly within your building or roofing project. The following steps will assist you gain accurate measurements while changing old flashing and installing new ones.
Tools Needed:
- A measuring tape
- Marker or chalk
- Straight edge/ruler
- Note pad/measuring sheet
Guidelines for Measuring:
1. Measure the length:
To find the total length of flashing, use a tape measure. Give yourself a few additional inches for overlapping.
2. Measure width:
For sufficient coverage, determine how wide you need it to be.
3. Consider bends and angles:
Measure any bends or angles accurately. You should add these figures to your overall length so as to have enough materials on hand.
4. Re-check measurements:
Before making cuttings, confirm all measurements are correct.
5. Cutting the flashing:

Galvanized Steel Flashing Types
Various types of galvanized steel flashings have been specifically designed to meet specific purposes and needs. Knowing about these types can help you choose the right flashing for your building or roofing project.
1. Step Flashing:
- Description: Primarily employed at a juncture of a wall/chimney and a roof, it is made up of small step-like flashings that are arranged to direct water away from the walls and roof.
- Use: It is applicable on roofing systems near vertical surfaces which enable it provide effective shield against water ingress.
2. Continuous/Drip Edge Flashing:
- Description: This long flashing is also referred to as drip edge flashing because it runs along the edges of roofs. The purpose is to avoid any water infiltrating under the roofing materials and instead channel them into gutters.
- Use: Protects underlying structure at roof edge from being damaged by rainwater.
3. Valley Flashing:
- Description: It is a channel that moves water off roofs and into gutters in order to avoid leakage.
- Use: The only way of preventing water damage in roof valleys.
4. Counter Flashing:
- Description: It acts as an additional defense over step flashing; covers the top edge of step flashing so as to prevent water from passing the flashing.
- Use: This material is usually utilized together with step flashing at chimneys and walls.
5. Base Flashing:
- Description: This type of flashing is typically installed at the base of a roof, near chimneys and other parts that are rising above it. Combined with counter flashing, it forms a watertight barrier.
- Use: It is employed where the roof joins vertical surfaces for instance parapets to prevent any seepage through them.
Cap Flashing:
- Description: Cap flashings or coping flashings are designed to cover and shield top edges of parapet walls or other vertical surfaces against potential ingress of water which may enter buildings from above.
- Use: Great for protecting parapet walls, etc., from rainwater destruction.
