A/C units in new home roof
Posted on 7/11/15 at 8:49 am

So we're struggling with the appropriate place to put our two new A/C units for our custom home. Of course our designer did not leave enough room in either sideyard setback and a variance is not an option.
So our options are: put them behind the master bedroom or in the roofline. Does anyone have any experience with putting the condensers in the roof? Seems like it would be a great way to get a leak! But a lot of houses are doing it that way in Lakeview. I'll hang up and listen.

See it done a decent amount

Every commercial building has them like that.
Just have them create a space that is properly drained and what not.

I haven't seen that done outside of the commercial arena....honestly, the only downside that I see would be that the unit is never in the shade if it is on the roof. would you have to build a flat area up there or what?...

Your only concern would be high winds during hurricanes. But with the right strapping and reinforcement, it's fine.

Yeah. I don't knitter much about units themselves, but I know they must be level.
Though you have to be careful about having a flat spot on your roof. Even flat toss have a gentle slope. Nothing causes more damage to structures than water intrusion.

Have you ever been out west? In a lot of places they are all on the roof. I guess they dont worry about the shade issue. Now i wouldnt want it right above my bedroom because of vibration and noise, but maybe build another flat area for them to sit and drain properly.

If you put them in the roofline, a crane would probably be used for a change out - I hate to be oblivious. I've seen techs rape someone over these charges

If you ever have a freon leak or something that needs to be done to one of those units, prepare to be charged for the tech to climb up there to address it.

EVERY flat roof will leak at some point. It's not hyperbole but a fact.

They are always put on the roof on the west coast. The unit would be in the sun a lot, but it also would have less dust and debris to clog up the fins. If it's done well I wouldn't worry about it. Any reputable a.c. company should have a genie lift that can do this without additional charges.

Flat roofs are great in desert areas. They suck in Louisiana.

Fire your designer or send them a bill for added expense

You guys are all thinking it has to be a flat roof. Where i have seen it the have metal brackets that attach to the roof with longer legs on one side to level it out. You dont have to have a flat roof.

True. Or he could just go with tried and true window units.

Yea, I guess the big issue is the leakage. I would imagine you'd have to drain to the gutters

I admit I have never seen it done here in SWLA but I figured it was something like a solar panel set up. Still leak concerns though if you are bolting something on top of shingles. Roof tar is just like caulk in that it will need to be touched up now and then or else it will crack and leak.

This is what they do all around out west. If they dont like the look they add lattice work or something similar around it to block the view. Never seen jt done in la thou and dont know why.

I've seen it done a ton on post Katrina renovations. And every time I see it I wonder about servicing them. There's a lot of stuff you can do yourself, that is out of the question. But hey, they won't flood.
Edit: I'd talk to your ac people and see how much extra it will cost you in the long run to have them up there. Service, replacement, etc.
