When Is New roof Installation for Commercial Buildings Necessary?

Most commercial roofs last for decades, but when the time comes to install a new roof, installing it expediently is crucial for preventing leaks that cause expensive damage. The lifespan of a building’s roof depends on several things, particularly:

The quality of the installation job
The climate where the building is located
The material of the roof

This article focuses on knowing when to replace metal roofs. If a building has a metal roof that displays the signs below, have it inspected by a provider of roofing maintenance.

Missing Panels

The most obvious sign that a metal roof needs to be replaced is panels that are missing. Missing panels are typically the result of stormy weather, or the gradual deterioration of the screws that hold the panels in place. If the screws become weak, and the wind blows beneath the panels, they can easily fall away. If the roof system on the building is missing panels, it is only a short time before serious leaks develop.

Wide Screw Holes

The holes for the screws that hold panels in place gradually widen until they no longer hold the screws tightly – a condition that often requires installing a new roof. Wide screw holes typically result from years of temperature fluctuation, and the subtle movement of the panel due to wind or other factors. Regardless of the cause, widened screw holes allow water to leak beneath the metal paneling. The best way to detect them before they result in leaks is to have a provider of roofing maintenance inspect the building’s roof system semiannually.

Buckled Panels

Metal panels buckle due to weather exposure and incorrect installation. In the first case, years of exposure to fluctuating temperatures may warp panels, or the widening of the screw holes and the deterioration of joints may allow wind to raise the panels up. Regardless of what causes the panels to buckle, they pose two problems: they cause leaks, and they could blow away during a storm.

Deteriorated Joints

The joints where panels meet gradually deteriorate due to weather exposure. In addition to securing one panel to another, the joints are responsible for keeping water from leaking between the adjoining edges. Pitting, rusting, and corrosion along the edges are signs that the joints are beginning to deteriorate.

Leak Spots on the Ceiling

Perhaps the most reliable sign that a roof needs to be replaced are leak spots on the ceiling. Many building owners assume these spots are from leaky pipes, and hire a plumber before they consult a roofing company. The easiest way to tell the difference between roof leaks and plumbing leaks is to observe when they occur. If leak spots only grow larger only on wet days, they probably come from a roof leak.

Conclusion

Installing a new roof is an expensive proposition, but letting an old roof remain in place eventually leads to expensive water damage on the interior of a building. If the metal roof of a building shows any of the signs above, have it inspected by a provider of roofing maintenance before it is too late.
