What Are The Most Common Causes Of Metal Roofing Leaks?
One of the most popular types of industrial roofing is box-profile roofing sheets, because they provide a long-lasting, hard-wearing surface that is easy to install and requires little maintenance to keep it looking its best.
However, a commonly reported issue with older roofing sheets, particularly those that have not been installed properly, is leaks, water damage and other issues caused by water damage.
Fixing a metal roofing issue requires you to identify the issue, find the right solution, and determine whether repairing the existing sheet or replacing it entirely is a better option. Here are the most common causes of roofing leaks and how to fix them.
Deterioration Of Roofing Materials
The most common reason for a leak in a metal roof is a breakdown of roofing materials.
Whilst this can affect all kinds of roofing materials and indeed is more common with shingles or asphalt tiles, the larger and long-lasting nature of metal roofing sheets makes it more pronounced and noticeable.
Metal roofing lasts a long time, but neglect can affect this lifespan significantly. It may be necessary to replace any sheets that are beyond repair.
You can buy dedicated kits designed for patching small holes in sheet metal roofing, whilst removing rust and applying a rust-proofing primer layer can also help.
Loose Fasteners
Roofing sheets rely on being correctly installed, which includes the right fasteners being installed correctly.
Over time, fasteners can get loose or damaged, which creates holes that can lead to leaks.
Thankfully, many of these can be fixed by simply tightening the loose fasteners and replacing those that you cannot fasten due to damage or being blown off the roof.
Damage Or Inadequate Sealing
A weatherproof sealing layer is vital to protect the interior of your building, but it is possible that it can come loose or get damaged over time. Make sure to use high-quality sealant materials around vulnerable areas, particularly the flashing, joints, fasteners and other places that water can get in.
