My breezeway and garage have 2x4 rafters :(


Guys, house was built in the 50's , the rest of the house is 2x6 construction but for some unknown reason the breezeway and garage is 2x4 24 ioc!! I am converting my breezeway to a kitchen. the entire room is gutted down the beams. What can I do to the rafters to make them stronger before closing up the ceiling?? As of now there are no structural issues and sagging but it bothers the hell out of me! the sheathing is 3/4 in pine t/g


thanks guys!!!

Are they 2x4 trusses with metal strap plates at the intersect points?

I find it amusing and sad at the same time your breezeway and garage has stood just fine for 60 years and houses built today, with all the supposed technology of vapor barriers, venting, yada, yada, yada, won't live to see that ripe old age.

I say leave it alone so today's warping, twisting, bowing, cupping lumber won't contaminate yesterday's real lumber.

yeah it is pretty damn incredible I have to admit. Simple yet it works, 3 10 d nails at each end, no straps not thing. I was thinking of adding a 2x4 strongback going across just to help out and make me feel better.

How long are the rafters and the width across the room, wall to wall where the rafters sit? What size is the ridge board? Thanks

I dont have the all the info for you right now. the ridge is amazingly 2x4 as well! the room is roughly a 10 x 10 room. I do not know how long the rafters are at the moment. it is a small roof , I will have the length tomorrow. I am thinking roughly 6-7 ft in length

The 2x4's may work for their span. http://publicecodes.cyberregs.com/ic...?bu2=undefined

Depends on any snow load, etc. that the Building Inspector could call you on. Converting a breezeway to a kitchen (living space) will require a permit, if used in your area. That way the structural safety, energy (insulation/air-sealing), and fire codes (including electrical) will give you minimum code protection to keep your family safe, and satisfy your H.O. Insurance carrier if ever a claim or when you sell the house.

Here you go guys. Any comments on how can make this stronger is appreciated. Again, NO structural issues at all. I just dont care for the 2x4's and how the ridge just ends with no support under it???


the rafters are 5' 5" long.

Add a simple support post on either end of the ridge. You could also add another 2x in between each current rafter, or just sister them. Honestly its not really a big deal. If it has held up this long with NO problems....but if it will make you sleep better

The ridge board ties the rafters together, pp12; http://www.awc.org/helpoutreach/ecou...seV09-2007.pdf
Rafters can be butted together, or gusseted, or fastened to a ridge board, per code.

Your location may or may not require collar ties, per code; http://www.awc.org/helpoutreach/ecou...seV09-2007.pdf

Yet collar ties may be removed, depending on where you live; http://www.finehomebuilding.com/how-...llar-ties.aspx

The rafter/c.joist connection is most important, last chart at bottom; http://publicecodes.cyberregs.com/ic...002_par023.htm

Page 179, add some 2x4 members between rafter/c.j. to make a “truss” system, if still worried about strength; http://books.google.com/books?id=bwt...page&q&f=false
