Our San Luis Obispo deck resurfacing experts know that a single mistake
during construction can compromise the integrity of the whole balcony
– after all, we fix these mistakes for a living! In this blog, we
take a look at three surprisingly common issues that lead to
leaky balconies and roof decks.

1. No Slope
A properly-waterproofed balcony will typically have a very mild slope,
typically about 2 degrees, which helps water drain. This slope should
encourage water to flow away from the house and doorway to prevent even
While a properly waterproofed deck will handle standing water just fine,
this can lead to premature failure if another issue arises. By sloping
the deck slightly, you will be able to prevent many issues that commonly
pop up, and you won’t have to worry about puddles of water on your deck!
2. Improper Flashing
Flashing is essentially just a piece of sheet metal, and is commonly used
in home construction wherever there is a seam that water can get through.
On a roof, it is typically placed around the chimney and skylights. On
your balcony, it will be installed around the perimeter of the balcony,
and around any columns that are framed onto the balcony.
Installing flashing isn’t very helpful, however, if it is installed
improperly. Flashing must form a completely watertight seal, overlapping
with one another to reject moisture. When properly installed, sheet metal
flashing will be sealed with special waterproof materials.
3. Punctured Membrane
In some cases, a deck resurfacing team will go through all the correct
steps, but will still produce a finished product with major leak issues.
The main cause? Holes in the waterproof membrane! After installing the
membrane over the flashing, construction crews must continue to cross
over this membrane to ensure that the edges and seams are fully sealed.
When they aren’t careful, they can puncture holes in the membrane,
effectively ruining the attempt at waterproofing!
