What are the best methods for fixing roof flashing?

The best ways to repair your roof flashing depend on the extent of the damage, the area of the roof where the flashing has been damaged and how the flashing has been damaged. Throughout this article, we will provide you with five simple ways how to repair your roof flashing.

The five easiest methods for repairing roof flashing include:

  1. Clean & Seal
  2. Replace Damaged Sections
  3. Reattach Loose Flashing
  4. Use Flashing Tape
  5. Speak With A Professional Roofing Contractor

1. Clean & Seal

The clean and seal approach is ideal if you notice that your flashing is suffering from minor damage, a localised issue where water is seeping through the roof in one specific place or as a temporary solution whilst you await professional roof repair from a qualified roofing contractor.

Once you have investigated and found the affected area, start by cleaning the affected area thoroughly to remove dirt, debris, and old sealant. Use a wire brush or scraper to eliminate rust and corrosion. Once cleaned, apply a new layer of roofing cement or silicone caulk to seal any gaps or cracks in the flashing. As mentioned, this is only a temporary fix and won’t be a long-term fix to your leaking flashing.

2. Replace Damaged Sections

Another method to fix your damaged flashing is by replacing a damaged section entirely. This method of roofing repair is for more serious and extreme cases where your roof has been damaged extensively due to extreme weather, extensive rust or corrosion and needs immediate repair.

This type of repair should be left to qualified roofers because without the correct skills, tools or methods, you could cause even more damage to your roof costing you more money on repairs. If you notice that your roof flashing is damaged and you are experienced remove the damaged part carefully, cut a new piece to fit, and secure it in place using roofing nails or screws. Ensure that it overlaps properly with the existing flashing to create a watertight seal.

3. Reattach Loose Flashing

If you notice that your roof flashing has become loose or is no longer secure on your roof, you will need to reattach it. The most common reasons why your roof flashing becomes loose is due to the fact that it is old and deteriorating or it has been subject to some weather damage such as strong winds.

To reattach your roof flashing use roofing nails or screws to reattach loose sections securely. Apply roofing sealant or roofing cement around the edges to reinforce the seal and prevent water infiltration.

4. Use Flashing Tape

Flashing tape is a useful flashing repair method if you notice that your roof flashing has a small crack or requires a minor repair that can be fixed by using flashing tape. You can also use it as a temporary fix in weatherproofing emergencies where you notice the water is getting into your home but you have not had time to get a qualified roofer to repair your roof.

In cases of minor damage or small gaps, flashing tape can serve as a quick fix. Clean the area thoroughly and apply the tape over the damaged section. Ensure it adheres tightly to create a waterproof seal. Please remember this is only a temporary fix and you will need a roofing repair expert to come out and repair the roof for long term security.

5. Speak With A Professional Roofing Contractor

As mentioned previously, attempting to repair the damaged flashing on your roof if you have not had previous experience in roof repairs is not the best option. Not only can it lead to you causing further damage to your roof and property but also can be a serious health and safety risk. For these reasons, if you do not have the required experience, it may be best to leave it to the professionals. We recommend scouting the local area and reading reviews on the best local roofing companies in your area. From here you can make a choice on deciding on the best contracting company for your roof by getting a professional to come and identify the issue at hand and repair it swiftly.
