How to Install Flashing on Metal Roof in Reading

Welcome to A1 Roofing Reading the leading metal roofing company in Reading, Berkshire, and the South East of England. We have helped countless homeowners and businesses in the area save on roofing costs by providing top-notch services and advice. In this guide, we will walk you through the process of installing flashing on a metal roof, which is an essential part of ensuring that your roof is waterproof and durable.

Understanding Metal and Flashing

Metal is a popular roofing material due to its durability, longevity, and aesthetic appeal. However, it can be prone to leaks if proper precautions are not taken. Flashing is a material that is used to seal the gaps and joints between metal roofing panels, as well as the areas where the roof meets the walls, chimneys, skylights, and vents. It is usually made of galvanised metal, which is a corrosion-resistant material that can withstand exposure to the elements.

Materials and Tools You Need

To install flashing on a metal roof, you will need the following materials and tools:

  • Metal roofing panels
  • Galvanized flashing tape or strips
  • Adhesive
  • Concrete form foundation
  • Footers (concrete or other suitable material)
  • Walls of the house or building
  • Home forms or foundations
  • Screws
  • Sealing washer
  • Drill gun
  • Caulking gun
  • Measuring tape
  • Level
  • Utility knife
  • Metal snips
  • Hammer
  • Safety gear (gloves, safety glasses, etc.)

Steps for Installing Flashing on a Metal Roof

  1. Begin by preparing the roof and ensuring that it is dry, clean, and free of any debris or obstacles. This will make it easier to work on the roof and ensure that the flashing adheres properly.

  2. Measure the area where the flashing will be installed and cut the flashing tape or strips to the required length. It is important to ensure that the flashing overlaps with the minimum suggested by the manufacturer, as this will provide a watertight seal and minimise the risk of leaks.

  3. Make sure the overlaps are secure and adequately sealed. You can use an adhesive or screws to hold the overlapping edges together firmly. Screw the metal roofing panels onto the roof onto the flashing.

  4. Move onto the next part of the roof and repeat the process until all flashing has been installed.

  5. Pay close attention to the areas where the roof meets the walls, chimneys, skylights, and vents. These are the areas where most water infiltration occurs, so make sure that the flashing is applied properly and that there are no gaps or openings.

  6. Apply flashing tape or strips on the walls of the house or building on all sides. This will ensure that water does not seep through the walls allowing a waterproof barrier between the home and the roof.

  7. Install gutters onto the roof to direct water away from the home. This will help to prevent water damage and leaks.

  8. Once you have completed the installation, seal all edges and seams with caulk. This will ensure that the flashing is watertight and will prevent any leaks from occurring.
