winterdd Posted December 16, 2019 Share Posted December 16, 2019 oh boy, i'm pretty good with roof planes but this one has got me. attached is the plan file for an addition to a home used as a veterinarian. the existing home has 8:12 pitch. the rear addition will be a hip of 4:12 and i have to make this work. it creates a nasty roof plan no matter what. i have to think realistically and know that the existing roof will be covered by the new addition roof. if i'm not clear just let me know. anyone wanna take a shot at this? it's horrible. the pic shows the rear of the home that attaches to the addition. chimney will be removed once project has started. thanks guys. also, what makes it even more fun is the new addition will be 9' drop ceilings. the existing home is 8' drywall ceilings so im catching hell all around. haha vet.plan Link to comment Share on other sites More sharing options...
winterdd Posted December 17, 2019 Author Share Posted December 17, 2019 another view, arial, green is addition i'm adding. Link to comment Share on other sites More sharing options...
DzinEye Posted December 17, 2019 Share Posted December 17, 2019 I would ask why they won't do 8:12, but I'm sure you must've done that already and they have their reasons. If your green lines represent the new roof plan, I would advise to not hip down back toward the house but rather run the two new side roofs together as a ridge back to the house. I would also suggest removing the little 8:12 pop-out on the left then let the new roof frame over that area and California frame over the existing roof as needed. A little cricket is needed on right for where what I assume is garage roof will adjoin the new roof . If they won't remove the little bump-out, it's the same thing but will need another little cricket on the rt. side of where the little bump-out hits the new roof.

winterdd Posted December 17, 2019 Author Share Posted December 17, 2019 The client called today and wants the rear of the addition a hip. It was a gable. The green doesnt represent the roof, just overall addition. I broke the lines on the new roof planes and it looked good from above but once u cut a section the existing roof looks horrible. Pretty sure they wont remove any of the existing roof to tie all this in. Link to comment Share on other sites More sharing options...

winterdd Posted December 17, 2019 Author Share Posted December 17, 2019 i'm not extremely happy with it but i'm going with the jogs in the roof line. when i cut my wall sections this is when autocad comes into play and i can manipulate a cleaner view. it is what it is and what the client wants. a good builder will make this perfect. i'm not settling, i'm a perfectionist but you gotta know when to move on and get the plans done.

You'll also need a little one on left if you have to frame around the small pop-out. I just noticed you must've posted a new pic of slightly different size of addition after I commented. Looks like you have it figured out about right. Link to comment Share on other sites More sharing options...

Perhaps Rip the left hand roof ( what's left of it) off and resheet in with main plane X in pic instead..... Link to comment Share on other sites More sharing options...
DG1949 Posted December 17, 2019 Share Posted December 17, 2019 How about a small "transition" room (similar to a breezeway), and then a separate roof altogether. Link to comment Share on other sites More sharing options...
VHampton Posted December 17, 2019 Share Posted December 17, 2019 The ridge on the small hip roof on the right should travel across. Then it can valley down on both sides nice and clean. Basically, it's still a cricket, but one that totally eliminates a snow or water catch. Also, agreed that the small hip on the right is a strange anomaly on the roof. It shouldn't be there. The new hip roof will basically be "over-framed" on top of the existing. Just wondering why the plate heights aren't all the same? It would be a cleaner looking addition perhaps, if the fascias all lined up. . 3 Link to comment Share on other sites More sharing options...
winterdd Posted December 17, 2019 Author Share Posted December 17, 2019 Fascia's are different heights due to a 24" increase overall in ceiling heights. I went up to 10' walls with a 12" air gap for drop ceiling per the clients request. Existing building/home has 8' ceilings throughout. Link to comment Share on other sites More sharing options...
DzinEye Posted December 17, 2019 Share Posted December 17, 2019 Maybe try to push them to do 8:10 pitch at 8' plate to match existing roof/fascia then do tray ceiling at 10' to get the height Link to comment Share on other sites More sharing options...
VHampton Posted December 17, 2019 Share Posted December 17, 2019 Hey Rob. I had a few minutes during lunch today to have a look. If you tried a hip roof to match the existing house (on the rear of the kennel), It may harmonize a bit more with the existing dwelling, rather than having a really wide, low pitch hip on the back. The center section to bridge the gap between both old and new can be 3-1/2 in 12 - which is perfectly fine for shingles. Either way, good luck with your project. All the best.

VHampton Posted December 17, 2019 Share Posted December 17, 2019 You're very welcome. Maybe they are being driven by budget. Your initial instinct is a much better design solution than what they might be after. In any event, the jumbo hip roof can definitely be framed on top of what's there. Even that funky little hip roof. Link to comment Share on other sites More sharing options...
