I would not care for any of the options as they all look like a compromised add-on, with the back of the roof angling downward from the side view. I would want a flat ceiling and a gable roof forming a pediment. More money, I know, but the look is permanently good.

I don't think a continuation of the roof at the same pitch angle would look like a compromise. A pediment would be great but I'm not going to spend $25k on this cover.

Part of the problem is a continuation of the roof at the same pitch will put your roof height at about 6' by the time it reaches the end of your patio........................

By "compromised" look, I mean that it appears, unequivocally, as an add-on ... like a lean-to shed type structure. Not that this isn't done all the time. But it LOOKS a bit "country" ... like a "corner has been cut" ... because that's exactly what has happened! Also, in future years, should a change need to be added to the roof, it is severely limiting and may preclude going forward with other options. There is not a cost just at the time of construction. There is also a hidden future cost that shows up at resale time. A prospective buyer compares appearance to other homes he's evaluating, and he also evaluates the cost of correcting a deficiency if it doesn't work for his needs. Option "A" or "B" may be like shooting yourself in the foot.

As pointed out, option A & B (in my picture) substantially limit the ceiling height at the outer edge of the patio. "A" is really unworkable ... but it depends on your actual roof pitch calculated to the patio edge. Option "B" works, but has the aforementioned appearance and functional limitations in addition to being the worst for snow load and shedding rain. It may require a flat roof type of roofing ... which most people find unattractive. Option"C" is the only one which looks integral to the original architecture and causes neither negative ceiling or appearance issues. BTW, you should be evaluating the cost DIFFERENCES between option A, B & C. If "A" cost $24K and "C" cost $25K ... it is a no-brainer that "C" is easily worth the $1K difference, whereas it would not be worth a $24K difference.

Option "C" is the only one that eliminates the quandary posed in the initial question of the thread.

@millworkman Actually the height would be about 8' at the end of the patio. Starts at about 12', with a pitch of 12/4 means it'll come down 4' over a 12' span.

I would double check all the measurements. I don't know how you could be starting at 12' height if the inset porch ceiling is 8' (which I base on the door.) And a 4' drop from the eaves is actually huge.

That awning is sounding like a good alternative to a roof extension.

@Yardvaark see my comment above for option A, it would be perfectly workable in my scenario. But I do understand your points, and I appreciate your detailed reply.

This is a long-term house for us, so it's not just about resale value and potential buyer accountability. I 100% agree that your option C would be preferred, and if I had a roof line that the pediment could work into more easily, I'd seriously consider it. But, I can do much of the work in option A myself, so the cost there is substantially lower. I got (rough) estimates from $25k all the way to $50k for option C. Since the patio span is 34', the pediment would be monstrous, and would have to be integrated almost all the way back to the peak of the roof. I estimate that I can install option A for well under $5k. Admittedly I'm just forming ideas right now and I haven't put together a detailed cost breakdown sheet yet, but suffice to say a pediment is simply not an option for us.

There's also option 'D', where I decide not to cover the patio, or maybe just build a free-standing pergola. I haven't counted that out yet, but after seeing some examples of option A/B covers, I like them, and think they can look very nice and well integrated if done right.

@GN Builders L.L.C Thank you for that reply, this is another option we're considering.

Your points taken.

@Yardvaark That is a 9 foot door. We have 10 foot interior ceilings. :)

I don't see a problem with a shed roof (B); it's not uncommon for patio covers so I don't think it would look out of place. I kind of hate option A because of what it does to your ceiling height. I don't think you'll be very happy with the finished effect.

What jumps out at me is, how are you handling where the roof cover intersects with the gable over the bumpout? Or are you stopping the roof short of that? In terms of attachment, I think ledger attaching under the soffit is a mistake because again, it will drop your ceiling. You could do rafters/sleepers laid on the existing roof and with some good carpentry, maintain the ceiling height and have a nice clean look.

With snow and wind acting on the roof, and this being a DIY build, I'd strongly recommend working with a structural engineer. A past employer sent me to Denver for a bit, those winds are no joke. I also think $5k is super optimistic for anything that'll be rock solid and trimmed out well, even DIY. $5k installed by a pro is a non-starter.

David nice YouTube video...Gotta love DIY working in slippers and cutting rafters on the lounge chair.

@GN Builders L.L.C HA! True. That being said, looks (at least to me) like he did a good job. If you have any concerns about how he did it, I'd love to know.

@Revolutionary Gardens I planned to handle the intersection (assuming I went with option A) in the same way as the youtube video I referenced in the original post. If I went with option A, I was thinking my build would be very similar to his. You say you don't like this option because of the resulting ceiling height. You don't think 8' at its lowest point is desirable? Seems like it'd be plenty for me.

I agree $5k is pretty optimistic. This is just a rough number based on what I saw in that video. I have a structural engineer coming by this weekend for a consult.

8 ft ceiling would be fine if it was continuous. Since you're starting with a much higher ceiling on the existing covered patio, it's going to feel more open if you can carry that across the space.

Gotcha @Revolutionary Gardens, I see your point. The steeper pitch underneath the cover might be a bit odd. Maybe I could just lessen the pitch and go with a 12/2 (minimum for asphalt shingles) or 12/3. The roof wouldn't look like a continuous slope, but that might not be such a bad thing.

If Arcadia has a Smart Pergola Rep near you you might want to consider a motorized Pergola. Good for your situation. Not cheap but if you can keep it to one motor it might be in your budget range:

@thinkdesignlive I'll check that out, thanks!

With the winds, snow, hail, etc that the Denver area experiences along with quite variable swings in temperatures, I would want something retractable I think. I really am not fond of the shed roofs in A and B, either practically or aesthetically.

@David Potter Looks like a weekend warrior job without inspections.I don't know how long it will last that roof but i know for sure it wouldn't pass inspection here...

Not to mention it looks like he only puts a few nails into the top of a notched existing rafter which looks like 2x2, IMO first good wind and it will uplift that roof right off.

As cutting on the lounge chair goes, I'm glad it's a chair and not his buddy or a neighbor LOL

@GN Builders L.L.C That picture is hilarious.

I'm guessing he just pinned the porch rafters onto the existing rafters because the new ones are set in far enough so they rest on the exterior wall and on that ledger board he installed, to take the bulk of the weight. I'm not saying this is a wonderful idea, just guessing regarding his justification for doing it that way. Maybe he came in afterwards and installed rafter ties to that ledger board?

I know nothing about structural engineering, but I'd say that if you really want a roof over the patio, option B appeals most to me. I think that option A would look really odd.

Option C probably would too, with that large a span. Also, from what roofers tell me, every valley you add to your roof bumps up the cost when it's time to re-roof. I'll take a simple, boring straight roof any day. A straight roof also better if you want to add solar panels later (assuming it faces the right way).

With all that said, I'm having trouble seeing any of them as very attractive. I'm no decorator, but in my mind, whatever you put there is going to close up the house and make it look less welcoming.

That patio is 374 square feet. It'd be a little tight, but a single person good at planning could probably live with reasonable comfort in that much square area. Honestly, I think you may have made the patio too big to have a roof.

@DavidR we've also considered only covering half of it.

So for those still interested, I'm considering this product:

https://www.costco.com/Gala-Bronze-10'-x-18'-Patio-Cover-Awning.product.100455265.html

It is rated well above wind and snow load requirements for my area. I like the dimensions and I can anchor it directly to the slab. Seems to be well reviewed. If anyone has an opinion about it, I'm all ears.

It is handsome.
