The Caribbean construction industry has relied on various types of screw fasteners to build just about every commercial and residential property you see. While screws are commonly used in the Caribbean, are they are not always required when it comes to installing metal roofing panels.

Typically an architect or builder decides on a specific design for a project, including the roof, then homeowners get to choose the type of roofing material they want (be it asphalt shingles, tile, or metal). Homeowners generally lean toward aesthetics with little interest in how the roof will be installed. But, from now on roof installation,  maintenance and performance after installation should rank pretty high on a Caribbean homeowner’s selection of roofing materials process.

Predominantly, the 5V Crimp metal roofing panel has long been the look of choice. This offers homeowners an accessible, affordable and familiar product which is available in the classic galvanized steel look, as well as a variety of colors.

Despite its popularity, roofing contractors are now steering homeowners away from using the 5V Crimp metal roofing panel due to the substantial number of screws required for installation. These screws create holes in both the metal roofing panels and the roof deck. Not only does this take away from the beauty of the 5V Crimp panel, but each screw penetration through the metal and into the roof deck is a potential leak.

So in this case, the multi-use metal roof screw fastener gets a bad rap. From the perspective of roof maintenance, homeowners should be aware that over time these screw fasteners have a tendency to back out of the decking, creating the potential for leaks. Additionally, if not correctly installed screw fasteners can be the source of leaks early in the roof’s life cycle, or the washer can fail prematurely.

Ultimately the use of screws in exposed fastener metal roofing can be risky.

StealthBond eliminates the need for screws and replaces them with a structural adhesive. For the first time in the roofing industry, metal roofing profiles that required exposed screw fasteners for installation can now be installed without them, eliminating the potential damages caused by metal roof screw fasteners.

The StealthBond adhesive for roofing will allow the roof to maintain its looks, prevent leakages due to corroded screws and prolong the useful life of the metal.

So, while metal screws have previously been the friend, they over time, become a foe. Why not use an alternative method and have a friend to match the longevity of your Caribbean villa?
