Is your Aluminum solid top patio cover leaking from rainwater or dripping water from excessive moisture in the air?
Remember, know the difference between these two issues carefully before you try a fix.
In our coastal communities here in Orange County, California coastal moisture can roll in at night and may bring the wetness with it. Sometimes moisture can build up due to this fog and knowing that this is a typical issue and not due to rainwater leakage. What happens? The surface of aluminum products do not absorb moisture from mist, as wood structures will; thus, this build-up happens. Don’t worry, this is normal.
Real leakage occurs in different ways. The most common leaks happen when the patio cover becomes overwhelmed with rainwater. You will see the results when the covers gutters and downspout systems have not been cleaned or maintained seasonally.
Overwhelming the system occurs when other roofs above the patio cover drains onto the patio cover below. Some people avoid this issue altogether, and we always recommended that all roofs above the cover should have a gutter and downspout system. Water leaks will occur, and there are no warranties if your patio cover is being overwhelmed from rainwater from above.
Another issue is when the patio cover is attached to your fascia board without its gutter and downspout system. Because again, other roofs are dumping water onto the patio cover, overwhelming the system all at once. If this occurs still there is no guarantee of waterproofing.
How to solve these issues:
Add gutters and downspouts to all of your house fascia boards above the solid patio cover keeping the rainwater away from your aluminum patio cover. Solid top patio covers are only designed to handle its stormwater on its own. Some people don’t care until a leak occurs, but that’s a different issue altogether.
Another way is to add more than one scupper or downspout to your aluminum patio covers gutter to make sure when this occurs, the water has somewhere to drain. A scupper is a deflective shield that attaches to your gutter channel and pushes the rainwater away from your cover. If your cover has designer columns installed, we tend not to use downspout and replace them with scuppers. Downspouts look bad when they are attached to your beautiful columns.
