Over time the screws on your roof can degrade for a number of reasons, including the natural expansion and contraction of the metal, people walking on the roof and damage from exposure to the elements.
Screws corrode and rust, causing corrosion and rust to the roof itself. Damaged screws can also create leaks, leading to a range of other issues for your property.
Screw replacement is a great way to prolong the life of your roof. It’s practical and cost-effective and will pay off in the long term.
