Is Your Roof Leaking? Blame It On Your Roof's Flashing

by Vanessa Lord

A leaking roof exposes property such as furniture and electronics to water damage. It also increases the rate at which your roof deteriorates -- given the fact that water seepage usually leads to the rotting of wooden support structures and rusting of fasteners. This can lead to huge business losses that can make your business spiral out of control.

It turns out that most commercial roof problems can be traced to faulty flashing. Here is what you should know about the relationship between your roof leak problem and your flashing. Being aware of this relationship will come in handy in helping you in not only detecting but also preventing roof leaks.

Flashing installation mistakes and leaks at roof seams and roof joints

Roof flashing usually comes in handy in deflecting water away from potential leak points such as joints and seams created at points where structures such as chimneys meet the roof. By shielding joints and seams from water exposure, roof flashing plays a significant role in waterproofing your office premises.

Since flashing material is normally different from the roofing material, there is a difference in the rates at which these materials contract and expand. This difference expansion and contraction rates creates tension that then cause the flashing to break away, exposing your roof to water infiltration. Termination mistakes also reduce the effectiveness of the flashing to guide water away from seams and joints, something that then increases the risks of roof leaks.

Flashing installation mistakes and roof blow-offs

Any openings that result due to termination mistakes or expansion and contraction usually do more than simply increase the risks of having leaks at the joints and seams of your roof. These openings provide entry points for air, something that then increases the risks of blow-offs.

When strong winds blow over your business premises, they reduce the pressure above your roof's surface. Any wind that finds its way through the openings at flashing areas then increases the pressure inside your premises. This then creates a net upward force that can create loose joints and pull fasteners off your roof structure. It weakens the overall strength of your roof while also exposing your property to increased risks of water damage.

If you are having roof leak problems, your flashing is likely to blame. Starting your leak detection process by looking for loose flashing, signs of rusted flashing materials, and improperly terminated flashing will help you save time.
