Metal Roofing Advice?
|

| Do any home owners have recommendations?
I have been looking at metal roofing shingles for over 2 years now, and
I have to make a decision.
I live in Florida. I replaced my roof (myself) 20 years ago with
standard asphalt shingles. They have turned into junk and now I have to
re-shingle. Since I don't ever want to have to do this again, I am
looking at metal shingles, but am having trouble deciding. Due to deed
restrictions, I need to stick with shingles.
The top contenders are
stainless steel millennium tiles: http://www.millenniumtiles.com
stone coated steel: http://www.decra.com/shingle.htm
painted galvanized:
http://www.tamko.com/ProductDisplay...ype/productD...
which are listed in decreasing price order.
The stainless look best from a theoretical standpoint, but appear to be
very labor intensive to install. They offer a Zalmag product which
would be less expensive and work very well too, but it has almost the
same installation disadvantages. In addition, both of these cost the
most and would really look the most unusual. The stone coated steel
look the most like regular (junk) asphalt shingles, but I think are
very pricey for a steel based product. There is a Gerard equivalent,
but it costs about the same. The Tamko product is the lowest cost metal
shingle, but it appears to be fairly thin and is only Kynar coated G-90
galvanized steel.
I am aware of other metal shingle manufacturers, but Follensbee is too
expensive and those aluminum shingles with exposed fasteners wouldn't
be workable in Florida.
To anyone having experience with metal roofing: Please post comments
that can help me decide what to do. Also, I would like to see
recommendations on where to buy these for the best price.
I would REALLY appreciate your informed comments about this topic.

Well...20 years - you definitely got your money out of them. Some of
the newer dimensional shingles have 40 or 50 year warranties. It's the
right time of year to do shingles, whether metal or fiberglass.

The best time to do shingles in Florida is in the blazing sun of the summer.
The installers DON'T pull that plastic strip off the back, but in 30 days
the shingles will bond in the 90 degree heat, and they will temper in the
daily torrential downpours.

Yes, crimped standing seam.
2nd place would be 5-V ribbed.
They are number 1 and number 2 in wind resitance.
The birds don't like them, and their droppings wash right off in the next
rain.
Squirrels don't like em either, they slide off.
First off, I like the metal shingles in the first link below, they look
cool.
I've been designing homes in SW FL for forever so I will give you some
general thoughts.
If you are anywhere close to where the paths of the recent hurricanes ran
you will be suffering to get any roofing work done now and in the indefinate
future. All the roofers are loaded up.
There are issues regarding the wind velocity ratings. The 1st link shows a
rating for 110 mph which won't be allowed around here. 110 is usually at
least 15 to 20 miles from the coast.
The shingles in the 1st link were used in homes long ago (20's - 30's),
there are still some over in the oldest sections of Fort Myers and they seem
to hold up very well. So given that they are not seen much anymore you'll
have difficulty finding a roofer to install them. If you intend to install
them yourself then there is no issue except finding someone to signoff on
the inspection.
Will the *powers that be* allow the product to be used?
Yes, we now live in the USSA so you only get to use the land with
permission.
This is also true for local deeds and restrictions or covenants.
Get all of this stuff in writing BEFORE you lay out the money for the
product.
If I were you I'd at least speak to a local roofer in person about what you
are wanting to do and get his feedback.
I hope you install the metal stuff and if you do come back here and post
some decent pics, I want to see how they look.
BTW: I like bright and unusual colors, Chartruese, Magenta or Island Blue
for example.! ;-)

| I have seen firsthand that asphalt shingles really don't do well in
hurricanes, so they are really not a option I am willing to consider.
In addition, asphalt shingle warranties are pretty lame when it comes
to hurricanes:
http://www.palmbeachpost.com/storm/...s/shingles.html
Metal shingles make the most sense, due to their mechanical bond to the
roof and their innate strength. What I am pondering now has mainly to
do with deciding which metal shingle to use. The 20 year old but
expired shingles on my roof now were advertised as a 35 year guaranteed
shingle. It is well known that shingles in Florida do not last anywhere
near their 'guaranteed' life. Furthermore, the guarantee is pro-rated
for materials cost. Big deal. The labor is the main thing.

| Thanks for your recommendations. I looked at standing seam and like it
a lot, but the appearance thing with the deed restrictions would be an
issue. I also have concluded that anything with exposed fasteners is
out of the question. My house is in Safety Harbor, near Tampa. I will
be doing the work myself, which is why I am planning on doing it in the
next month or two. (I did the last one myself too.) Metal is going up,
just what kind I am not sure.

Good for you Steve.
I hope you can make it work.
Remember to post some pics if you get it done, I'd like to see it.
I'm in Cape Coral, about 125 miles south of you.

No kidding.
Have you read the warranties of the metal shingles you're thinking
about?
The Millenium Tile warranty gives you no coverage - for 50 years! Two
different types of tile, one good to 110 mph the other 150 mph, but
with that warranty specifically excluding hurricanes...what's the
point? I'd wager that most times winds are over 100 mph, it's a
hurricane! Weasels.
The Decra tile are good up to 120 mph and their warranty is much better
and covers "reasonable replacement costs" for 20 years before the
prorating kicks in.
Tamko weasels with this sort of "answer" in their FAQ:
Q. Can I walk on my METALWORKS Steel Shingles roof?
A. Since METALWORKS Steel Shingles require virtually no maintenance,
there should be no reason to do so. {Right. No reason. How about
repairs? Sheesh.} Like any roof, care should be exercised. You can
discuss specific details about walking on your roof with your
installation company. {Discuss details with the installation company?
The manufacturer is passing the buck to the installer}.
There are other choices:
Metal
http://www.duraloc.com/signature_series.shtml
Their Signature series has some good features. "It is Class 4 hail
tested (this is the highest hail rating achievable) It is warranted
against winds of 120 miles per hour which makes our metal roofing
systems popular among high velocity wind zone areas such as Dade County
Florida and throughout the Caribbean. Dura-loc Signature Series has
surpassed the highest 150 mph wind uplift (-126 PSF) requirements for
Exposure "B" outlined by the Florida Building code. Tests conducted by
UL on the Signature Series achieved -270 PSF. This Series is also
highly energy efficient, its batten mounted installation method; allows
for constant airflow in which provides far more heat energy savings."
That last part will keep your house a _lot_ cooler in the summer.
If you're not locked into the metal shingles, Certainteed has one of
the best warranties out there. For their 50 year shingles they cover
labor and material replacement for the first ten years.
http://www.certainteed.com/NR/rdonl...opped_final.pdf
There's always a weakest link in the chain. If your house gets hit
with 150 mph winds, I'm sure there are also other items that will fail
besides the shingles.

| I did look at the Duraloc, and liked them, except for the fact that the
fasteners are exposed. Exposed fasteners seem to me to be a generally
bad idea. I have investigated this and found that 5V type metal
roofing with exposed fasteners often has bond failure. This is due to
expansion and contraction of the metal causing hole enlargement, which
leads to seepage and wood rotting. The seepage/wicking/leakage that
would occur with the Duraloc system does appear that it would be
significantly less however, as it would have to go through 2 layers and
at a perpendicular angle. I will investigate this further. Thanks for
reminding me of this option.
Certainteed's guarantee illustrates that they know full well that their
shingles become much weaker with age and are far less hurricane
resistant when old. Asphalt shingles aren't even in the running.

Steve? Do you realize that you're posting to an architecture group and
asking for homeowner recommendations? You're not only off topic,
you're in the wrong place. The people that answered your questions
didn't get twisted in a knot and berate you - they tried to help. Why
do you feel that you can waltz in post one question, and then start
yelling at people about being off topic? Does that seem reasonable to
you? If so, please leave.

Not only that, but homeowners are clueless as to the performance of their
roof. What most will respond to will be centered around installation
issues--and those are indpendent of the roofing materials. Homeowners don't
maintain their roofs (for the most part). Homeowners don't know much about
what makes a good roof or not. Asking for homeowner recommendations is
asking for the uninformed to give you their opinion. Contractors and design
professionals will give better, honest answers than homeowners will.

Well there ya go, thats why our responses were not taken well by Steve.
We responded as professionals and he was expecting novices.
Hell, I'd be pissed too if I was expecting A and got B.
