Metal roofing? - mella l - 01-04-2006
Hey I don't hear any hammers humming along!! What's doing? Where did everybody go??? Toooo much holiday for y'all! Just took a lesson on good southern manners, any insult followed by bless her/his heart isn't an insult after all. Do you believe that??
Now that I have someones attention I really do have a question and I don't want to ask a roofing guy cause, bless his heart, I want the real skinny!!
Are metal roofs attached directly to plywood?
Are one by two strips used to attach the metal to the plywood roofs? Is an insulation applied to the plywood and then the roof goes on? Can you walk on a completed metal roof without worrying about damaging or denting it. Is it applied with screws and how does the roof then repel rain waters? Are any colors better or worse than any other color? I don't know perhaps I should just Google and check it out but say hey wanted to pick up a little after the holiday daze/shock/coma I was in!! LOL How about you!!

I don't know about metal roofs on a house.
We put one over the back deck. We use 1x4 pine boards to screw the metal to. The metal roof screws have a rubber washer on them to keep water from going thur the hole. We use hunter green being that the heat under the roof didn't really matter to us.
I would think white or light color to reflect the sun rays would be a good idea on the Island.
Hope you get more answers.

We used Goldcoast Roofers to do a special seamless metal roofing. Of course, it has seams, BUT it is designed so there are NO SCREW HOLES through the metal. Instead it almost snaps together and then the hardware is on the underside. It is not cheap but it is expected to have twice the life of a standard metal roof. The roofer imported our metal from Mississippi and it came on big rolls. Then he has a maching to bend it into shape... very interesting.
It is laid over the roof trusses with perlins across forming a wooden grid pattern. Workers have walked on it albeit gingerly from what I could tell. We chose not to insulate but have a large attic area.
We also chose an unusual teal green color. Hunter green is more common. Here on the Hilo side we get tons of rain and we have every reason to expect this roof to be the only roof we ever have to put on the house, with an expected life of over 50 years...
Hope that helps a little...

RE: Metal roofing? - HADave - 01-05-2006
Mella, I Believe...... unfortunately there is no short answer for the real skinny, except how deep is your pocketbook. Here is MHO
There are different designs of, different materials of, and different colors of.
The fluted, ribbed or corrugated are like metal siding you see on commercial buildings. Most of these have exposed fastners that require torque sensitive sealing washers subject to cracking over the years from drying out. There are now companies that make a prefab design with hidden fastners ( which I like ). The traditional standing seam is the prefered metal roofing of the deep pocketed residential elite, bless their hearts, hahaha, and does make for a more clean look especially in steep pitched applications. Those standing seams really catch the eye. I yike it, but only have a beer bottle budget.
All can be applied directly over any surface even an old composite shingle. The material beneath or fastened to can be strapping/purlin plywood/sheathing most installers will tell you to leave an airspace for energy efficiency ( strapping/purlin) but the air space leaves no support in the event one needs to walk accross the roof for repairs or plumbing issues etc. One thing about metal like your vehicle it will dent unless it is flat against a supporting material like plywood. To me no matter what you choose I highly reccommend ice/water shield beneath the material chosen, very inexpensive insurance against leaks. The prefab metals are precut to your roof you simply supply the required ordering info and it comes ready to install quick and easy for the diy..
Each manufacturer will have it's own installation instructions and standing seam will be professionally installed only because of the equipment required.
The following sites should explain all one would want to know...

We are very please with the metal roof we are orderind from HPM...we chose corrugated the Sand Green but I also liked the other colors they carry. Our area to be covered is 36'by40' with a small front porch and it comes in around $2000. We will have rafters with T1-11 turned down and tar paper then the metal roof screwed on. No foam strips so the roof can breath.

Aloha folks, back to work eh?
I might make a suggestion to choose your roof color by location.. When I built in HPP, it was down at the Makuu end of fifth,down in the sunny dry part. I used white, to reflect the heat. Here in the wet of Leilani, I have green, because no matter what color you choose, it's gonna end up green on it's way to turning black in a few years. My main house is going on 25 years old with the original corrugated, nailed down roof, and just now getting to the point where it's rusting away at the edges, I had it painted about 3 years ago. I figure it'll last 3-5 more years. The only leaks I have are in fiberglass skylights (bad planning, not my idea). The plain corrugated roofing BTW is by far the easist fot DIY, you can't go wrong by putting it wrong end up. A helper of mine did that on an addition here at my place last year with high-rib, had to leave it that way because of lack of materials. Also you don't have to make any long side cuts, just overlap it 'til it fits. Hey mella, here we call those hammers Hawaiian woodpeckers, the woods are full of 'em RE: Metal roofing? - mella l - 01-05-2006
Hi Guys, Just wanted to stir up the pot some! A little to quiet on the building site for me. HAHAHA
So thanks for all the suggestions. Nancy I love the sand green color, my favorite also! Mississippi isn't that where Elvis and the crooked politicians were born! Sorry couldn't resist!! Actually I missed the Elvis thing by a few years but have friends who are much older who were bitten hard! LOL! Seriously though;
HADave hate to admit it for public consumption, but say hey there neighbor, we got holes in the pockets too and they aren't very deep to boot! Thank you for the wonderful sites don't you just love that Bob V and his video clips! Seems like a pretty realistic guy to me. Just love the real skinny on this subject, precious!!
Hutch, our Lelani jungle guy!! You are our tried and true voice of experience and we do appreciate all you share. How long have you been on the island? Thanks for you thoughts on this also. I actually like the old corrugated metal roofs, cause my darlin grandma had them on her place and it was quite quaint and that is what I'm lookin for quaint. Only need it to last 30 years on the way outside!! LOL. Hers were turning to that rust patina after 45 years in the California gold country, by that time for us a nephew will have to deal with it!
Mahalo neighbors hoping to see you all soon, real soon, the sooner the better for me! Mella L

PS>
) We have contracted a D6 cat and made an appointment to meet us in February! Yes progress, slow but sure. He will scrape our driveway and a building pad, push my Hapu fern where I want them, let me look at the lava flow and formation, push the down fall into a specific area. Then I can make some decisions about what and where I want the D9 to come in and rip. Will be a little more costly but I want to have some natural lava flow areas in my yard to meditate, study, enjoy and plant around. The D9 will more than likely have to rip the driveway and the building pad and an area for trucks and supplies, as well as a septic tank area. Whew. OK good night Gracie! Over and out. Oh should I start a new thread about creating a drive way, how it is ripped, what the base is and is a topper needed all on lava? Do you need to run a compactor over it.

Aloha mella, we talked some about driveways on the site prep thread. Congratulations on getting started, practice counting to 10 and biting your tongue, It'll be aggravating at times. PS I've been here six years this trip, lived here twice before, once in the 80's once in the 90's, it may seem like this place is rural and primitive to some, but the changes (and improvements), since the 80's is astounding.
RE: Metal roofing? - David M - 01-05-2006
as for metal roofing, there is another alternative - Galvament. I'd say you need to plan from scratch for a new, not replacement roof with this as it may affect your support structure. The main reasons, we choose it: a. the roof and ceiling is one, no need to sheetrock, so once roof is on, the ceiling is also finished. b. it is insulated, so benefit for temp and sound control. c. User installable.

BTW, we choose Blue.
