Average Cost For New Garage Roof??

Page 2 of 3  


Mark's estimates weren't too far off, given the limited information available. Michelle described the shed as 16'x19'. We don't know the roof pitch, or the overhangs, but let's assume a gable roof with a typical 6/12 pitch.
6/12 pitch over an 8' span (half the building width) would work out to a 4' rise at the peak. Using Pythagoreans theorem, take 8' squared + 4' squared, then find the square root for 8.9'. Let's round that to 10' since we don't know the overhang. I'll also round up the length to 20' since we don't know the overhang on the ends.
That's 10'x20' feet or 200 sq/feet for each side of the roof, or 400 square feet for the entire roof. Using my local Home Depot prices that works out to:
13 sheets plywood ($17.50 for 15/32 CDX, or $10.37 for 7/16 OSB) - $227.50 12 bundles 3-tab shingles ($27 bundle, 3 bundles per square) - $324 1 Roll 15# roofing felt - $21
Round that up to account for nails and other extras the total is approximately $600. Of course, this assumes Michelle has the tools and skills to do the work herself. If she has to pay someone to do the work, she's probably looking at least twice that amount, not counting any additional labor costs to demo the original roof.
Of course, this is all meaningless if the underlying structure is rotten. No way to know for sure till the roofing and sheathing are removed, but rot sounds very likely based on Michelle's original description.

Thanks! Thats exactly what I was looking for, some actual prices! Well "rough/estimated" prices at least! One thing though, those prices you listed were for the materials. What do you think labor costs would be?
Also, yes you are right! We may do only 1 side at a time, because it's the right side of the garage roof that leaks worse than the left side. Yes, the left side leaks as well, but not as bad, only in a couple of small spots. The right side of the garage has a huge 20 foot high, Pear tree hanging over it, so this may be why the right side of the garage roof is worse than the left side!?

We had a 5-10 minute thunderstorm 2 days ago with some heavy downpours, and after the storm was over, we heard a loud noise come from the backyard ( where the garage is located ). We went out and looked around, and found out that the overhang on the right side of the garage roof was totally in ruins. The whole overhang just gave out, and crashed to the ground! Rotted wood, shingles, rusted nails, the garage siding everywhere all over the ground! Pissed off Hornets or Yellow Jackets flying around everywhere from a huge bees nest inside the overhang! The overhang must have filled with water, and the rotted wood couldn't hold the weight any longer and just gave out!?
Does this mean the whole entire roof is next to cave in!? Don't know whats going to happen to the 1979 Chevy Camaro father/son project car thats in the garage which currently doesn't run!?
Also, the 2x 4 beams that hold up the plywood are now all broken off where the overhang was, so now all the 2 x 4 beams are probably going to have to be replaced as well??

If the overhang was that bad, it shows you how bad the roof is as well, but does this mean the walls are probably rotted out as well??

Hi Michelle,

Unfortunately, that's impossible to know from here.
I usually do things myself, so I almost never pay labor costs. But, you can safely assume the labor is going to cost at least as much as the materials. With a repair or remodeling project, you're likely looking at more labor costs than material costs.

As I suspected, you have more damage than just roof shingles and sheathing. You have significant structural failure. With a garage of that size, it's not even worth the trouble to try salvaging anything. I hate to be the bearer of bad news, but it sounds like you'll have to tear it down and start new.

If you don't push it out of there immediately, it's probably going to be buried under a pile of rubble.

An overhang is just the part of the roof extending out past the wall. There shouldn't be anything to "fill with water". You may be thinking of the gutters (if there are any). Or the roof was so far gone that the wood was soaking up water like a sponge. Either way, basic maintenance has been ignored for a very long time.
Keep in mind an overhang usually only extends a foot or so past the wall. There's practically no weight on it, other than a couple rows of shingles. Now picture that 15 foot span across the middle of the garage. If the one foot overhang already collapsed, you can bet the middle is coming down soon also.
My advice, get anything you value out of that building now. Then knock it down and start over.
Take care,
Anthony

No, there are no gutters on the garage. But we suspect that there was a hole in the roof where the overhang was, because hornets were always flying in and out from right above the overhang, so water must have been getting in there!? And yes, you are correct, all the wood is absorbing water like a sponge. I went out there today, and climbed up the the step ladder, and felt around the roof. The roof was all soft, and my hand almost went right through the roof, WITH EASE! The shingles crumble in your hands, and you can break the wet wood apart with your bare fingers. Doesn't look good!

Ok, enough of this "average cost for a garage roof" messages.......
Lets concentrate on the average cost for EVERYTHING!!!!
Since everything has a price, the average cost for everything is somewhere between one cent and one million dollars.
Sure, there are those coupons worth 1/100th of one cent, which means that if you collect one hundred of them you can get a penny (which always seemed like a fun thing to do), but it also says they have no cash value. Therefore, you must pay one cent minimum to get anything and everything.
At the same time, few things cost over one million dollars, excluding commercial machinery, military equipment, government expenditures, and the homes of the most wealthy. Therefore, the high limit for most homeowners (remember, this is alt.home.repair), should be set at one million dollars.
Knowing this, the next time anyone on here wants a price for anything, simply tell them that they can expect to pay anywhere from one cent to one million dollars. You will be correct 99.999999999999% of the time.
Anyone want to know any prices now? I'm ready to assist!!!! (U.S. Dollars ONLY). If you use another currency, ask your mother (assuming they have mothers in foreign countries)....
Here is some helpful info:
Roll of duct tape - $0.01 to $1,000,000.00 Garage roof - $0.01 to $1,000,000.00 Hammer - $0.01 to $1,000,000.00 Cookie - $0.01 to $1,000,000.00 Cost to paint a home - $0.01 to $1,000,000.00 Installed toilet - $0.01 to $1,000,000.00 New home - $0.01 to $1,000,000.00 Replacement windows - $0.01 to $1,000,000.00 Microsoft windows - $0.01 to $1,000,000.00 Sex with a famous model - $0.01 to $1,000,000.00 Hamburger at McD - $0.01 to $1,000,000.00 5lb Box of 16d sinkers - $0.01 to $1,000,000.00 Tube of silicone caulking - $0.01 to $1,000,000.00 12 foot 2x4 - $0.01 to $1,000,000.00 Pot roast - $0.01 to $1,000,000.00 Pork and Beans (16 oz can) - $0.01 to $1,000,000.00 Furnace repair - $0.01 to $1,000,000.00 New Chevy truck - $0.01 to $1,000,000.00 HDTV - $0.01 to $1,000,000.00 Motel room for a night - $0.01 to $1,000,000.00 Gallon of gasoline - $0.01 to $1,000,000.00 Carpeting for the whole house - $0.01 to $1,000,000.00 Bag of dog food - $0.01 to $1,000,000.00 Roll of toilet paper - $0.01 to $1,000,000.00 Shot and a beer - $0.01 to $1,000,000.00 Sex with the President of the USA - Priceless!!!!

Hey, I need to know what's the average cost of a car repair?
Let me make myself perfectly clear. We need to know the average cost of the wealthiest 1% of Americans, who didn't pay their fair share, due to the Bush tax cuts.
I can think of better use of my time, than having sex with a Kenyan who smokes. Yech! Scuse me while I go vomit. Besides, he specializes in screwing the poor, while saying he wants to screw the rich.

re: "Mark's estimates weren't too far off, given the limited information available."
You estimated $600, Mark estimated $400.
That's a 50% increase, which many would consider "far off".
I know we're all just tossing out numbers based on very limited information, but I think even your numbers are way low.
The cost for sheathing around here is a bit higher than your numbers, but let's run with yours.
You added ~$27 for extras.
That $27 is going to be eaten up by at least half for drip edge alone and that's based on the cheap stuff. There's not a lot of room left for nails, blades, etc. After that there's no room left for tax.
What is the OP going to do with the old roofing material? Probably going to need a dumpster, don't you think?
As has been said 1000+ times in this group, trying to to get even ball park figures for these types of jobs over the internet is folly at best.
Actual on-site estimates are free. The OP should just pick up the phone, make some calls (at least 3) and get actual numbers based on her actual needs in her actual location. I'd be willing to bet that entire $600 that the actual cost of the entire job - without labor - will be at least 50% more than the $600 when all is said and done.
Rough guess: Double that if the OP is paying for labor.

Thanks for all of the GREAT information, but now that the overhang is totally gone, and laying on the ground, and the beams are ruined, it looks like it's going to be even more expensive now.

If we were talking $6000 instead of $4000, then yes, that 50% would be a significant increase. However, I wouldn't consider an extra $200 a big difference for a long term investment like a garage.

Yep, there are many extras I didn't account for. I pulled my prices off the Home Depot web site this morning to work through this little 10 minute thought experiment, but there's no guarantee those prices would be the same when I got to the store.

For a small project like that, I would probably just toss the debris in my utility trailer and run it to the dump myself. Of course, the dump fees still cost money that I didn't factor into my rough estimate.

I agree completely!
