Unattached Roof

Stuey Dee

Looking at a job requiring a new wood framed, metal topped gable roof to be fastened to the existing flat roof. Seems the previous homeowner built the new roof and the only thing keeping it on the old flat roof is the weight. Any suggestions?

Grumpy

Call a qualified carpenter to tear off the old flat roof and reframe the roof structure as necessary. Then hire a qualified roofer to properly install a new roof, metal or otherwise.

I suspect if the roof was that poorly framed maybe the whole structure is junk too.

I make no assumptions, but could you nail it together? Is the existing in terrible shape?

Retrofits of flat roof to pitched often require fastening to the flat roof and perimeter of building walls.

Well guys the roof has already been built and there is no way the homeowner will agree to tearing it down and rebuilding it. As for nailing it, well half the house has a regular composition roof over wooden decking and the other half has a metal roof. I agree that it must be fastened to the old roof/structure but was asking for ideas on how to do so. I fabricated an anchoring device that was approved by the local inspector and have begun installing these contraptions. Lot of extra work and expense to correct poor workmanship. Thanks for your help my friends.

After reading your post again, I see that you mentioned about fastening it down.
Your question would have been kind of open ended not knowing all the details.

But I would think that a convential sytem of metal ties, though beefed up and enlarged and maybe useing carraige bolts would work for the perimeter for the seat cut area on the rafters. For the center portions, some kind of piece of either cable, wood or metal attached to the collar ties or other framing used in that area held down with more bolts and fastened directly to flat roof then tarred over would work.

I thought you guys might enjoy this as much as I did. Stuey sent me a private message.

wow grumpy your on a roll .... that makes what........ two strikes

Grumpy

Not sure what ya mean by strikes but I have found by sharing my opinion un-sugar coated people tend to get hurt feelings. I call 'em like I see 'em.

noreast05

just referring to the above pm and the comment from the new guy on the peter framing video thread. seems like the linch mob is out for you.

Probably won't be the last guy either! Grumpy's got a pretty thick skin along with his opinions. If there are any contractors here that don't have a thick skin when it comes to their opinions, they won't be in business long

Grumpy

When aren't they? This truly happens on every forum I am a meber of... Is it me or them?

Note to stuey dee: Don't take it so personal. Grumpy's name is...."Grumpy"! You should read some of his responses when he's in a bad mood Just keep posting, this is the internet after all.

I like un-sugar-coated responses. Too many people in today's society need to be coddled along and patted on the back for comfort to even exist in their daily lives. Intended for nobody in particular.

Honestly I am not sure how I offended the guy. He asked for a suggestion and I told him what I suggest. It's the same thing I suggest when ever someone asks questions on how to do something. It's what I do when I don't know how to do something.

P.S. We do only very very very minor framing, and won't do any framing without a print. I like having the security blanket of having the architect's or engineer's stamp on the print... not to mention it is required by code in the cities I work in. Also I'd like to say I am a better roofer than carpenter, but I am a better carpenter than most, not all, roofers I know. A project like described I would sub to a carpenter for sure, then put the roof on the structure he builds.

Seems he took it as a personal affront, - - not realizing you're not really talking directly to him, - - but only to a paragraph.

The poster from above, I think reads a lot of the posts and just finaly spoke out. I dont think it was this particular thread that set him off but many.
IMO

The tarring realy would not be even needed, because you now have fully enclosed the flat area and now it is an attic space.
If you look at trade magazines with retrofits useing metal framing they bolt it down and tar over them

AaronB.

Grumpy, dont forget that most roofers we know are on some sort of substance abuse or in the program. LOL LOL LOL LOL
