Ahoy! Roof Experts

Sorry for the delay in my response.


Allen, in post #27 you have what I would think is the way to go. However, I forgot to mention that the existing roof is a hip and not a gable. This cuts the ridge distance down so I have not been able to duplicate what you.

I hate to admit it but I am stumped trying to get the client a good look. It looks great with a 4 pitch cathedrial and all will match. But, it turns out that the framers want to deal with trusses and not long rafters.

I guess you'll just have to get some real framers...

My framer handframed sheated and paperd this entire roof in 2 days with only 2 guys...when it was 11-20° outside. In fact 2 guys framed the whole project in only 1½ weeks..with an extra man to help stand the gable walls one day.

I think framers these days are just getting lazy....with all their pettibones, lifts, and what not...I still carry steel up a ladder on my shoulder to set it in a garage...

Paul - tell your framers you'll being them pizza one day if they do the hand-framing....

Chris, - Up here, we sometimes call the ridge skylight you show as a Belvedere skylight. I was thinking that you could combine the exterior design feature of this type skylight with a Sun Tube. The Sun Tube is more energy responsible and no doubt brings in more light. Any thoughts or comments on this idea?

Trial and error..
Maybe Tim O would know the formula to work it out..
It is not going to look good..
I did some thing like that for a friend back in the 80s..Looks like a boat upside down..

[slatta]

figure out the angle in cross section, I don't know how to make a sloped ridge though

Paul,

This would be easy to figure out in an elevation or cross section as Neal suggests.

...and sloped ridges are easy. Look at the baseline angle box.

[Allen42acj]

Guess you could keep it covered with a tarp..
Now I know how to get the angle,thanks..

[louis]

Way to go Allen.

[Allen42acj]

Thank you Louis
Still think it will look like an addition mistake..

[slatta]

I agree allen, just because we figured out how to do it does not mean we should do it

thanks to louis we'll have to live with it

[louis]

I did not say it looked good.

[Allen42acj]

Just my Chief skill are good

Dimensions did help everyone - good work so far - how about the existing terrain to the rear, if there is negative 3' or so - try dropping the whole addition to hide the new roof lines behind the existing, seems like 3' plus/minus is what you need.

Personally, I don't like the way it looks. The stick builld transition between the original roof and the new trusses [if they are the same slope] is not that difficult. We used to make a ridge board cut square on the new truss end and a #/12 cut on the old roof, level it and nail it in. The cut "rafters" that have a ridge cut on the uphill end and a COMPOUND cut on the bottom. All can be done with a portable skill saw.
Snap string lines from the ridge for guide and nail a flat 1x8 onto the old roof right over the shingles. Cut right and left sides to match for lengths and make sure they are perpendicular to the ridge. I'll try and draw and post something if time.

Tony,
Flat lot but good idea.

John,
looking forward to seeing what you are suggesting.

Client is still evaluating possible roof plans.
