Hello,
I'm wondering if anyone has used structural insulated roof panels for their roof?
Once the rafters are up these seem to be the easiest way to put the roof and have it insulated in one step.

It sounds like there is a confusion of terms here. A sip (structural insulated panel) has osb on both sides and has a structural rating. You do not need decking when you use a sip, as it is structural.
If it has osb on one side only, it is nailbase, and is not structural. You do have to use a deck with it.
Most sips com with wiring passages already in them. You just drill holes to intersect them.
I chose to use sips on my home. I had 9" log rafters on 4' centers. The sips I used were 8.25" thick total. They would actually span 8' but I didn't want my rafters on 8' centers. I also used jumbo sips. My house is 36' long so I used an 8' x 24' and an 8' x 20' sip end to end. This gave me a 4' overhang on each end.
Very tight, very well insulated roof. Had to use a crane to set them, but 1 day did it.

I have built 2 homes with structural insulated roof panels made by Raycore. SIPS have a reputation for being expensive, but I found the Raycore panels to be very affordable and extremely efficient. I would recommend them to anyone using an exposed beam style roof system.

Hello, I am not doing a log home, although I did once, with my husband.. great structure. My current roof is failing. I have spoken to Raycore and they suggested perhaps a vented roof. 2 x 4's over panels and then osb decking above that to create an air space. Has anyone done that, what would be the advantages? I live in NC, where summers have gotten really blistering.
Thanks...Tokala
Failing roof

Almost all roofing systems need ventilation. If there is no air space in your roof now then what Raycore suggested would be the easiest way to fix that, adding of course a Ridge Vent and some perforated soffit of some sort.
Advantages are that your roof will not fail. lol Moisture can build up underneath your roofing material through a variety of methods and what the air space does is allow air to carry that moisture away back outside. My roof was leaking like crazy awhile back and I discovered that I had no roof vents. All I did to fix it was punch a hole in the side of the roof(where the gable is) and voila! No more leaking!
EDIT: I should state before someone corrects me that I am refering to Northern climates. SIPS don't require ventilation in warmer climates, or areas that have mild winters. Though I would put them in anyway just to be sure ;)

Thank-you, for the sips roof answer. The current roof is vented, plywood was installed over insulation, with airspace, using too small of nails so it is buckling up. Our summer heat was very harsh this year. Our winters are not extreme, heat comfortably with my most excellent Woodstock Soap Stone wood stove. It is the best!! However summer temps stayed in the high 90's, most of the time with little night time cool down. I spent untold hours on line, looking into different companies and Raycore flet the best. Since the OSB will not be attached to the panel, should a problem arise, what ever piece of OSB, that had a problem could be replaced, without the whole panel being lost.
Any and all suggestions are appreciated, since I have never worked with this before. Have a great day!

I was wondering about what it does cost to do a roof with these panels ,what thickness did you use and what size was the roof,I've heard they were expensive also but what's expensive just some kind of an idea would help put it into perspective

If I were you I would contact a salesman at raycore.com to be sure, they were great to work with. I used a 5.5" thick R-42 for around $5.15 or $5.25 a sqft and needed over 6000 sqft. I found them to be pretty affordable and less expensive than sandwich panels and did not need a crane to get them on the roof. They also have a 7.25 R-52 ( not certain of the price). They even have a "Hybrid" system to use with trusses or I joist rafters that sounds interesting to me.
The big selling factor for me was the savings on my heating and cooling bills!!!
Oh, they also have a 3.5" thick R-26 panel for locations that do not need as much insulation.

That was not an installed price but they seemed to go on about as fast as decking and no crane needed. I believe Raycore needs exposed beams. First the beams, then T&G then the panels then roofing. Their salesman told me they do many homes in Jackson/Pinedale WY area due to the extreme cold temps in the winter.
Good luck!
raycore pricing
we asked them for a quote on our 35x35 roof 6/12 roof. the quote they gave us was more than $15,000. NOT a very cost effective option for us. will have to find another way. too they said the quote not only didn't include putting them up but that WE would also be responsible for getting them off the truck!

I have not been to the site for awhile and noticed your comments about pricing. That was so high I was shocked!! Kind of crazy but I called them with the spec's you listed and they gave me a regular price quote for $8736.00 for 52, R-42 roof panels and mentioned a sale price bringing it down to $8137.00. Way different than the price you mentioned. I think that is affordable! That is good news as I want to use them again on our next place.
Cool news
It's great to hear that prices have gone down. Thanks for the heads up.
I would look at another
I would look at another company. My roof was about that size and I did my roof and whole house in panels for 12,000 delivered. Getting them off the truck is easy. Remember, on the roof you can do nail base (only one side osb) when you put down t&g decking. This makes them lighter and cheaper. A nail base 4x8 panel is not very heavy. Alot of people can handle one by themselves. You just get it on the roof, screw it down, great stuff the seams and put your felt paper down.

How do you do the wiring on the roof?
You can route a channel in a
You can route a channel in a beam and drill through the beam to poke your wires through. Or you can route the foam in the panels.

Route right into the panels and back fill with canned foam. Works great!
SIPS go above beams and
SIPS go above beams and decking, so beams and decking are exposed.
SIPS roof panels...interesting company...Ray-Core

I've checked their website as previously mentioned up this thread. www.raycore.com
These panels seem like the way to go. Great R-values and it would seem that you get a lower profile fascia.
Has anyone else used these or checked them out? Seen or experienced any problems?
SIPS Estimate
Ragdump,
I am building a 40x40 log home in N. Alabama. I got an estimate from www.sipsteamusa.com located in Bainbridge, GA. It was for a 5 1/2" thick panel with OSB on one side. Estimate was $6500.00 plus shipping. I also got an estimate from a company in Louisville, KY. They were around $8,000.

That sounds like a good price BUT. I noticed that you are in N. Alabama. That price is about what it would cost me for foam alone. I wonder what the R-Factor is that you are required to use. I have to use R-38 on my roof
Brian Landry
They have foam thicknesses
They have foam thicknesses for any climate and R rating. The price will be higher for thicker foam, but just figure the number you need and get some quotes on that thickness. If you are building the house yourself, as I did, the money you save in getting your roof on quicker, and with less help, really made the decision for me. Plus, if you read about the SIP panels they are impressive for other reasons besides just ease of construction.
Brian
You also have to take the thickness of the roof decking, (2x6 T&G), to get the total R-value. I'm not positive, but I think the R value for a cathedral ceiling in N. AL is R-22 to R-38.
hey rgdula e mail me
were in collinsville,ms , me and my wife would like to come see your progress
I used Sips from sipsteamusa
I used Sips from sipsteamusa on my roof. If you order "nail base" which leaves the OSB off on one side it is cheaper. I used 5 1/2 inch thick. Worked great and went on QUICK. just count up number of 4x8 panels needed and get quotes. It will save you alot of time...just remember that.
sip's
I really like the idea of sips... but they are very expensive. We have discussed other alternatives in the members area and my roof is an example.
