Who Should Inspect Deck’s & Balconies?

 “Leys makes a good argument that even the other groups identified in the draft bill—general contractors, architects, and engineers—aren’t qualified to perform these inspections, despite their skills and training.”

Andrew Wormer Editor Professional Deck Builder Magazine

If California’s Senate Bill 721 is adopted without modification by that state’s legislature, periodic inspections of enclosed balconies and similar structures on multi-family buildings that are higher than 6 feet above the ground would be required statewide. This is a common-sense measure, especially in light of the Berkeley balcony collapse in 2015 that killed six students. But as Bill Leys points out in an interesting post on PDB’s LinkedIn group, one of the groups that would be authorized under the law to perform these inspections, make repair-or-replace recommendations, and certify that repairs have been properly completed are structural pest control licensees.

What Deck Flashing Is For (Hint, It Ain’t for Waterproofing)

Here at DeckExpert.com, I often hear someone say “the flashing leaked and the deck failed”. I always ask, how did the flashing leak? In my opinion, if the deck waterproofing system is installed in such a manner that the entire piece of flashing, the horizontal piece nailed to the deck and the vertical leg that goes up the wall is completely embedded in waterproofing, the flashing basically cannot leak. Drip edges covering the building materials below won’t leak unless the coating has lost it’s bond with the metal. I often find that happens when gutters are nailed through the drop of the drip flashing and the metal is deflected.

The misnomer in my opinion in the industry is to think of flashing as “waterproofing”. It is not primarily waterproofing. What the flashing is for is to provide a termination point for the deck waterproofing system to end to. Metal flashing is simply what we use to do that.

Now let me clear, the flashing’s still must be integrated properly into/with contiguous weather resistant barriers that are being installed by other trades-where building paper comes down and over the flashing for the deck. Sequencing is essential when it comes to installing weather barriers and typically the low slope roof and deck areas are weathered in first.

Edge/drip flashings still must be installed in a manner that they are placed over building materials below them so water runs over, away and off.

Flashing materials are commonly galvanized/bonderized metals, copper and stainless steel. When using any of these, proper preparation of the metal is essential prior to terminating the coating to it. Bright shiny galvanized I don’t recommend at all as it’s very difficult to clean and prep properly in the field for our work’s requirements. I recommend “bonderized” metal flashing instead. It’s basically clean so it usually just needs to be wiped down with a damp rag to remove dust and contaminants.  Copper and stainless steel both require being sanded heavily to “etch” the metal. I use a 4″ grinder with the sanding flappers in a 50-36 grit paper to cut into the metal.   I then prime the metal with a liquid based mix of the base coat so it’s loose with polymer and I brush it out onto the flashings. I then use fiberglass and resin to finish waterproofing the vertical legs of the wall to deck. See picture below for an example. Completely encasing the L flashing makes sense to me, it eliminates the possibility of water sitting at the wall and finding metal to attack.  I’m also seeing this detail in Pli-Dek and Duradeck’s details, and I hope to see other manufacturer’s follow suit if they haven’t already.

So what’s your thoughts? Comment below please.

Prime all metal flashings before installing coating system!

Impossible to waterproof this termination! Deck waterproofing MUST extend up the vertical leg, behind the stucco paper.

A door is already in, the deck can’t be waterproofed correctly. The door must be removed for the flashing to be installed.

A Reader Asks The Deck Expert About a Tiled Deck

The Deck Expert answers readers questions for only $25.00 Recently one reader asked us this question about his tiled deck.
“I saw your site on the web.
I have a tiled exterior deck. I have discovered it was not hot mopped before laying tile.
Obviously, it leaks.
I have been advised to use sealants but they don’t waterproof.
Is there any product that will waterproof the tile without removing the tile, hot mopping and retiling?” 
Jay Q Los Angeles
Our Answer
Dear Jay,
Sadly there isn’t any sealer that will waterproof the tile. Sealers will help reduce moisture absorbed into the tile and down through the mortar bed, but will never succeed at actually waterproofing it.
A proper waterproofing system for a tiled deck is installed prior to the tile and mud bed being set. A pre-sloped substrate is waterproofed with a membrane suitable for tiling over, then a drain board is set on the waterproofing to allow water that does get through tile/grout/expansion joints to evacuate to a drain or an edge.
Hot mop waterproofing is pretty much a method of a by-gone era and isn’t used much anymore. Your deck I’m afraid will need to be completely stripped down to the framing and rebuilt. If you want to put tile down again, you’ll need to hire the best craftsmen available, using the best industry standard methods for framing/substrate and the waterproofing and tile assemblies.
You should expect that this will run an average of $70 to $100 per square foot for a complete rebuild, a little less if you go with a walking deck system that looks like tile. The picture above is a decorative faux tile walking deck system from Pli-Dek.
