When it comes to protecting your commercial roofing materials, there’s no one better than the pros at Knockout Roofing. Our roofing contractors can help with everything from roofing repairs to re-roofing and commercial tear-off, all with your business’s protection and best interests in mind.
We have an extensive commercial roof inspection checklist that we use for every commercial building we service. This list includes numerous areas we’ll inspect in fine detail for you, from parapet walls to field seams and drains. One item that appears multiple times on this list, and justifiably so due to its importance for roofs everywhere: Flashing. What exactly is flashing, why is it so important to your building’s roof, and what can happen if it’s damaged or not installed properly? Let’s take a look.
Flashing is a protective seal on the outside of various roofing types that acts as the first line of defense against moisture and water intrusion. It’s vital for areas common in commercial buildings, such as skylights, vents, chimneys, dormers and others – these areas are generally at higher risk for water seeping through them and entering the building in areas it shouldn’t be in. When installed correctly, flashing provides a comprehensive blocker to all moisture damage, protecting your building from water damage, mold, mildew, and even major flooding concerns in some cases.
Where It’s Important
As we noted above, flashing is important for any area that’s at higher risk of water entering through cracks or other penetrations. Flashing is vital at all edges, valleys, joints, gaps, intersections, grooves or projections of any roof structure, regardless of the material actually being used. These aren’t the only areas it can be used in, however – flashing can be part of the roof at any location.
Flashing Damage and Effects on Roof
There are two primary ways flashing damage can take place: Via improper installation that leaves it imperfect to begin with, or as a result of storms or other weather events that wear it down over time. In the former case, you may not recognize the signs of improper installation until it’s too late – the flashing may appear to be installed correctly, but you only realize it’s not when it wears out prematurely a year or two later. This is why it’s vital to have professionals like ours at Knockout Roofing install these kinds of materials in the first place.
In some cases, particularly if you live in an area where extreme weather is common, flashing damage may be unavoidable. If major weather events happen in your area regularly, we recommend inspecting your flashing or having our pros take a look regularly to ensure it’s in good shape.
