My add-on room in the back has 2x4 ceiling rafters!


I'm very surprised the roof looks is flat as it does if you had that much snow on it. Obviously something makes it stronger than it should be. Do you know how thick the plywood is? What is that 2x4 going across the rafters in the second picture doing?

PM me with your e-mail address.

Actually,that's in good shape for being 50 years old---

It's not going to collapse soon-

Post a picture from a bit further back---If you do rebuild the roof --I suggest going higher up onto the house roof ---it'll look better---and shed water --standard shingles could be used if you can get that to a 3/12 pitch.

Doing that yourself is not advanced carpentry or roofing----Mike---

No plywood, it has approximately 1x6 tongue/groove boards. I think that 2x4 was there to support the rafters by bracing them against the ceiling joist 2x4s, if I had to guess.

I'm not sure if I don't have enough posts yet, or if I am just missing it, but I don't see an option to PM you.

I'm glad to hear it's not in danger of collapsing, but I don't really understand what is supporting it. Last year we had snow for 2 weeks that was 3-4 feet deep, how did that roof not collapse under the weight? If it's in no danger of collapsing, should I just sister the rafters for now, or should I still look into replacing and repitching it now?

I should add I am not certain on the age of the room. It could be anywhere from 50-20 years old. I believe from the conversation with the lady I bought it from (she and her husband were the only prior owners of the house, but she couldn't remember a lot due to age) that it was built back before the 70s but after the original house in the 50s.

A picture farther back of the roof or the rafters? I would definitely like a steeper pitch.

The only thing I would have to do to go higher up the roof is move a vent pipe I think. Or Could I just extend it up through the new roof that would be higher?

Depends a lot on your budget--your shills and your time---Adding 2x6 sisters to the rafters will give you a lot of added strength---as to the ceiling joists--that could be sistered also--

You need to decide what you want that room to be---and how nice looking and how maintenance free-

Also how warm---

The way it's built now looks shabby with the flat pitch--and rolled roofing--

Insulation is not an option----no place to put enough to make the room toasty warm--and no ventilation to keep the roof deck truly dry.

You have to do what you can afford---new better roof structure and insulation will not be a huge expense if you have the time and are willing to learn and do it your self.

If you must hire a carpenter the cost might still be affordable---Mike---

I definitely would prefer a sloped roof. The room will be a little entertainment room. I am most concerned right now about structural stability over exterior aesthetics right now, (Or, I should say, that's what I can afford to care about right now). But if I could do the roof for around $1K I would definitely be interested. I do have a friend who owned a roofing company for 20 years. But if it would be more, I would really rather just make sure the room is structurally sound, as insulated as I can, and waterproof.

The sloped roof would be nice because I could also use the can lights I really wanted that won't fit in the 4" space I have towards the wall.

Invite your roofer friend over to take a look---Most long time roofers have some roof framing experience---he could offer some suggestions.

Whatever you end up doing you need to address this. The load of the roof bearing on toe nailed blocks is not a good thing.

Iím surprised how well thatís all held together.

Oh, I should have taken a better picture. Those blocks are not actually supporting the ceiling/rafters. I think they were just put there to put up the paneling. The ceilings joists and rafters go behind. Those boards are barely attached, I have ripped a few off actually to get behind them.

I probably will. I just want to know my plan before I invite him over... He typically works in only a manner he knows, if that makes sense.

Not to be a nuisance, but would it be possible to get summaries of what I would need to do in terms of a "proper fix" (i.e. re-pitching the roof, etc) and also what I could do just to make sure the roof will be solid and structurally sound and safe from the elements? Not necessarily a step-by-step, just an overview of what would be involved in both?

Also, to do 2x6's I will have to lower the ceiling a bit, basically to the height of the door as the room is a step-down from the rest of the house. I am guessing that is not a big deal?

I suggest you take a breath and go back to the fundamentals. This roof has apparently been there for 50 years, so clearly it is strong enough to survive. Before you go "repairing" it, consider the simple question, if it is so grossly underbuilt, why is it still there? There is a lot of strength in old growth wood that is not reflected in current codes, which generally assume you will be using relatively low quality, currently available lumber, so this roof may be built with stronger lumber.

Second, the only significant vertical load on a roof comes from snow and ice, and the occasional impact from a falling tree. I exclude tornadoes and other serious wind events, those loads are complex, and are generally not considered vertical loads. So here is a possible option. The next time you get some snow on the roof, hire a local unemployed person to shovel off your roof. You can do this with a snow rake without even getting on the roof. That should extend the life of your roof through many more winters, at least until the roofing fails, then you get that replaced.

Since you lack the funds to properly frame the project, but clearing snow is relatively low cost, at least consider that option, and leave the roof as is until you can afford to upgrade.

Thanks, I more meant what would be the basic steps of doing that rebuilding. I assume I would cut the roof open where I would be attaching and tie into the roof rafters on the main house?
