What to Look for After a Storm

What to Look for After a Storm

Commercial rooftops are not impervious to storm damage. That can be a problem when summer storms come along – and unlike many residential areas, it can be more difficult to tell if a storm caused any damage to a commercial roof until serious leaks have already developed. Let’s look at some of the roof damage we’ve seen these storms cause to commercial roofs.

Tears

Even mild storms can bring a surprising amount of wind, and commercial rooftops are often quite exposed. This is a bad mix if the storm starts blowing a lot of debris onto the roof. Tree branches, trash, and other pieces can blow across your roof during bad storms. Heavy objects can also come loose and crash against the roof. Dragging anything across a commercial rooftop can be dangerous because the surface materials may tear. This creates an opening for rain to enter and start a leak problem.  

Flashing and Deck Damage

Flashing refers to the metal strips at the roof's edges, while the deck is wooden support used underneath many rooftops. Flashing is made to be durable and to protect vulnerable parts of the roof. However, it can warp and sometimes even rust over time, making it weak. A good storm can come along and dislodge or bend weak flashing, allowing moisture to seep into the cracks. This gives leaks easy access to the deck, where they can cause serious rot and mold problems.

Blow Offs

A blow-off occurs when a powerful storm creates a severe pressure difference in the air. Combined with high winds, this can sometimes literally rip off part of the roof or at least partially detach it. This tends to occur with older, run-down rooftops that need to be replaced or rooftops with poor designs for the area.

Debris and Clogs

It’s not just heavy debris that can cause trouble during a storm: Small debris like leaves and twigs can cause problems when they pile up on a roof. This can encourage mildew and moss growth, but the more immediate problem is clogged drainage channels. Commercial rooftops need drainage, especially during storms, to funnel off rainwater.

Standing Water

A poorly designed commercial roof, or a roof with drainage problems, can lead to standing water – where water has nowhere to go and ponds on the top of the roof, lingering for days before evaporating. This makes it very easy for leaks to develop.

Hail and Heavy Rain Damage

Hailstorms can be unpredictable and potentially damaging. Large hailstones and heavy hail can create dents and small tears on the surface of a roof. This weakens the roof overall and creates potential entry points for water that can develop into leaks.
