Griffin Hagle replied to Trip Smith's discussion Where to spend my marketing dollars?
"Trip, as someone who works to bring others into the home performance fold, I'm encouraged to see GCs independently arriving at the conclusion that shifting towards HP makes business sense. Best of luck to you in your new endeavor! Most…"

"Nate, no kidding, I didn't realize till just now that was your video! (I guess I should pay closer attention to my sources.) It's orders of magnitude better than 99.9% of what I see out here, and I've shared it recently in our…"

Griffin Hagle replied to Tom Conlon's discussion Whole House Fans - Love 'Em or Not?
"I was aware of but unfamiliar with them until moving to Southern California in 2012. After seeing several dozen of them, I can get behind their theory of operation, although I don't like the trade off of a compromised thermal boundary. From the…"

Griffin Hagle replied to Kim Tanner's discussion Bathroom exhaust fan shuts down two airports
"Good find. Reminds me of the domino effect in the Breaking Bad episode with the distracted air traffic controller. Glad no one was hurt in Chicago. This does a nice job of illustrating why our program's QA standards prohibit burying most bath…"

"Ken, I couldn't agree more; bungalows, Craftsmen, and American Foursquares are some of my favorite homes to work on (I'm a little jealous as I couldn't dream of finding a house like this in San Diego at the price they…"

Charles Bennett replied to Griffin Hagle's discussion Best practice recommendations for this vaulted ceiling?
"Griffin,   It looks like tar paper above the skip sheeting, so when you tear off the old roof you'll have nothing over top of the skip sheeting.  If indeed you want to have the existing rafters/skip sheeting now be the…"

Griffin Hagle replied to Griffin Hagle's discussion Best practice recommendations for this vaulted ceiling?
"Bud, I just talked to her, and the roof is about 15-20 years old now. So that's good news. I'm now heavily leaning towards recommending they replace the roof considering what's at stake. Like you said, it would be a shame to miss the…"

Griffin Hagle replied to Griffin Hagle's discussion Best practice recommendations for this vaulted ceiling?
"Hi Charles. Yes, I think I'm going to recommend they tear off the old roof and talk with the engineer and architect about building up/out. They have so much to gain (more headroom and thermal bridge elimination, as you pointed out, as well as…"

Griffin Hagle replied to Griffin Hagle's discussion Best practice recommendations for this vaulted ceiling?
"Jaime, Thanks for your reply. That certainly seems to be the simplest, quickest, and maybe R-value solution, and one they did ask me about. However, I'm hesitant about spraying foam on skip sheathing for a couple reasons: it seems like…"

Charles Bennett replied to Griffin Hagle's discussion Best practice recommendations for this vaulted ceiling?
"  That's some nice looking existiing wood, and not a lot of headroom;  maybe they should consider tearing off the old roof, adding some stained plywood or other, then re-rafter above the old roof with 2 x ?.  You could then dense…"

Jaime D. Gomez replied to Griffin Hagle's discussion Best practice recommendations for this vaulted ceiling?
"I'm not sure what I'm missing, perhaps it's that I work exclusively in the multifamily sector, but couldn't you just apply a two-part high density foam insulation and be done with it? The high R-value of the spray foam will more…"
