Welcome to A1 Roofing Bracknell! We are a metal roofing company based in Bracknell, Berkshire, South East England. We specialize in installing, repairing and maintaining metal roofs for residential and commercial properties.

Metal roofs are popular among homeowners and contractors because they are durable, energy-efficient and can last up to 50 years or more. However, one of the most critical components of a metal roof system is the flashing. Installing flashing on your metal roof is essential to ensuring proper waterproofing and preventing leaks, especially during heavy rain and snow.

If you're planning to install flashing on your metal roof in Bracknell, this guide will provide you with step-by-step instructions on how to do it correctly.

What Is Flashing?

Flashing is a thin, weather-resistant material typically made of metal that is installed on the joints, seams, and edges of a metal roof. It is designed to create a waterproof barrier between the roof and the walls of your home or building, preventing water from seeping in.

Flashing can come in different types, shapes, and sizes. Some common types of flashing materials include galvanized steel, copper, aluminum, and lead. The type of flashing you choose will depend on your roof's design, your budget, and your personal preferences.

Why Do You Need Flashing on a Metal Roof?

Flashing is an important component of a metal roof system that serves a critical purpose. Without proper flashing, water and other debris can seep into the gaps between the wall and roof, causing leaks, water damage, and even structural issues.

Moreover, flashing can also prevent pests, such as rodents, birds, and insects, from entering your home through the roof. Flashing makes it challenging for them to chew through the roof's seams and edges, which could compromise the overall structure of the roof.

What Materials Do You Need For Installing Flashing on a Metal Roof?

Before you begin installing flashing on your metal roof, you'll need to gather the necessary tools and materials. The most important things you'll need are:

• Metal flashing tape or strips
• Adhesive
• Galvanized exterior metal panels
• Concrete mix
• Form foundation or footers
• Wall screws or nails

Here's a breakdown of each material and why you need them:

• Metal flashing tape or strips: This is the primary material that will form the actual flashing. You will need enough flashing tape or strips to cover the length of your roof perimeter. You can purchase flashing tape or strips from a home improvement store or directly from a metal roofing contractor in Bracknell.
• Adhesive: You will need adhesive to stick the flashing tape or strips onto the roof and walls. Roofing adhesive is specifically designed for use on metal roofing, and it will create a strong bond between the metal and the flashing.
• Galvanized exterior metal panels: Galvanized metal panels are used to cover the flashing tape or strips along the roof's edge. The panels will protect the flashing from weather damage and give the roof a more finished appearance.
• Concrete mix: You will need concrete mix to form the foundation or footers for the walls of your home or building. The concrete will provide a stable base for your home's walls and help distribute the weight of the roof evenly.
• Form foundation or footers: The form foundation or footers are the structures upon which the walls of your house or building will stand. You will need to ensure that the form foundation or footers are adequately leveled and square to ensure that your walls are plumb and robust.
• Wall screws or nails: Lastly, you will need wall screws or nails to attach the metal panels to the walls of your home or building. Make sure that the screws or nails you purchase are strong enough to hold the metal panels in place and won't corrode over time.

How To Install Flashing on a Metal Roof

Now that you have all the necessary tools and materials, it's time to start installing flashing on your metal roof. Follow these steps carefully to ensure that your roof is protected from the elements and is installed correctly.

Step 1: Form a Foundation or Footers with Concrete

The first step in installing a metal roof is to form a foundation or footers with concrete. This step is especially important if you're building a new home or building from scratch as it provides a stable base for your home's walls.

To form a foundation or footers, you'll need to excavate the area around your house or building and pour a concrete mix into the holes. You should let the concrete cure for at least 24-48 hours before proceeding to the next step.

Step 2: Install Wall Screws or Nails

Once the concrete has cured, you can install wall screws or nails into the walls of your home or building. Make sure that the screws or nails go into the studs of the wall and are spaced correctly according to the manufacturer's instructions.

Step 3: Attach Galvanized Exterior Metal Panels

With the wall screws or nails in place, you can attach galvanized exterior metal panels onto the walls. The metal panels should overlap a minimum of one inch to ensure a watertight seal. The bottom of the panels should extend over the foundation or footers by at least an inch to prevent water from seeping under the walls.

Step 4: Begin Part of the Flashing

Once the metal panels are in place, you can begin installing the part of the flashing that overlaps with the metal panels. The flashing should be cut into strips and placed onto the metal panels. Make sure that the adhesive is applied evenly to the flashing and then press it down firmly onto the metal panel.

Step 5: Apply Adhesive and Flashing onto the Roof

Next, apply adhesive along the roof's edge where the flashing will be installed. Then, install the flashing tape or strips onto the adhesive. Make sure the flashing is secured tightly and overlaps with the metal panels on the wall.

Step 6: Add More Flashing

Add more flashing by laying another strip of flashing against the previously installed flashing. Make sure that the new flashing strip overlaps with the existing flashing strip and that adhesive is applied to both strips. Repeat this process until all the flashing is installed.

Step 7: Install the Remaining Metal Roof Panels

After all the flashing is installed, install the remaining metal roof panels onto the roof's surface. The metal roof panels should overlap a minimum of two inches to ensure a watertight seal. Screw or nail the metal roof panels securely in place.

Step 8: Check for Overlaps, Make Sure Everything is Secure

With the metal roof panels in place, check for overlaps to make sure everything is secure. The overlapping parts of the flashing should be at least one inch, and the metal roof panels should overlap at least two inches. Make sure all screws or nails are tightly secured, and the metal roof panels are not loose or wobbly.

Step 9: Ensure Proper Water Tightness

Finally, ensure proper water tightness by spraying water on the roof to simulate rain. Check if there are any leaks or areas where water accumulates. If you discover any leaks, reapply adhesive to the affected areas or replace the flashing altogether.
