| Your likely going to get all kinds of opinions but I suggest you carefully
go up onto the roof and scape a sample into a small glass jar. Take your
sample to a local university Extension Center. Most urban universities have
these extension centers that provide testing and analysis services. If no
extention center is in your area there is a hospital -- for sure -- that
provides testing services. You'll have to call around.
What you want to learn is the composition of the "black mess" before you can
reliably determine what to do.
I can make some comments about the North side of the roof being the same
side where moss grows on trees for example inferring the same principles may
be at work. You can use the web to search or do something drastic like going
to a library and asking a librarian to help you learn why moss grows on the
North side of trees. With that knowledge as an indicator at least you'll
have some basic information from which to proceed.

| If you find that this is mould, there are several solutions that you
can apply to the roof. We have a biodegradable solution, Batimoss, for
removing moss, algae and mould and it also leaves a fungicide on the
surface to protect it!

thank you, will check it out
yeah, most houses around these parts have it on their roofs
one theory a fella offered was... highly dangerous black mold
he claims it makes alot of people deathly sick...like spinal cord sick
(menengitis or something like that)
I'd like to know for sure, without having to submit it to a lab
everybody has it around here, maybe someone who knows for sure
will reply...i'd be happy with a semi authorative answer
but will check out the link you gave.

Home depot and such outfits sell a kit, 'petri dish' gel smear
container, then you send it to the lab and they send back a
result its not expensive... 30 dollars or so...best thirty
bucks you will ever spend.
if its black mold its a very real problem... if its endemic to
the area then it will pervade any damp spot in the house and
see the entire place with spores that have led in the past to
demolition of the building..
its covered up and officially ignored a lot due to the loss of
real property and tax base involved... a news paper that
printed a story about black mold would loose 80% of its
advertisers the next day.... do the test with the lab...
anon... if its black mold and 'everyone else has it'... a lot
of people stand to loose a lot of money. It will not be
possible to remediate the entire neighborhood, trees, dirt,
basements, sewers etc. Decide what to do accordingly.
it will be hard to get straight answers in the community...
as soon as black mold is announced publicly the whole mess
gets nasty....so what you have now is either no black
mold...or more likely black mold that the rich people in town,
who own the real estate want to keep in the unmentionable bin
or smoked over with spin, distractions and rhetoric.

I take it your talking about black mold
oh sure..mold shows up lots of places
it's just odd...im in a very moderate part of the country, but in this
town
which is ratty anyway! everybody seems to have the black toner looking
mess spilled down dey roofs
if it's black mold, im going to create a real scare and then start up a
black mold killing proprietorship!
Guaranteed! to get rid of the mess...
Ill tell them, their children could die if they don't get rid of it
I think this mess is very lethal

Sell your house first. But watch out, you can be sued for
non disclosure of the situation later.. you cant kill the
black mold by the way, some if it you can kill... but most of
it, is spores spread all through the structure.. the place has
to be torn down... if its all over the community... its a bad
deal to build there... and it can spread./
say a person moves from a black mold area and takes furniture
with black mold in it...in a few years that house can easily
be terminally contaminated.
There are simple 'cures' for black mold on the market,
designed as palatives for those in denial or who dont want to
loose their property value...but its really not a solution...
you need study the mess in depth. And dont let anyone know
you have the petri test dishes out.

For those who are alergic to the mold it can be lethal, for
some others its no problem at all... you need to research the
figures... a survey of the health of those living in the area
will tell you a lot...for that you need to know the normal
health demographics...how many in the US on average have
asthma for instance... if its 10 out of a hundred, and your
area is say 12 out of hundred its not statistically
significant..... if its 30 out of a hundred in your area...
then its a big issue.
A big part of mold remediation is drying the area out... you
will never dry the north side of the roofing... if its old
structure there are water leaks and dry rot that will host the
mold.
study dry rot, a different issue, but you will learn about
spores and runners in that study... you cant just treat the
spot... its anything in the same air space you have to
treat...thats why its a nasty issue.. mostly covered up, like
dry rot in Marin county...worlds richest real estate... nasty
dry rot problems the building dept ignores..

Hey Phil:
I never saw this black roof side syndrome till I went to NC. Then I sw it
everywhere...on one side. Some an even "coating" and some an even coating
with clean "runs". I thought it was just some nasty pollution.
The part that makes me reply to you is "A big part of mold remediation is
drying the area out... ". For two months daytime highs don't go below 90
degrees. It's always sunny. Attics are 5000 degrees (pick any scale). You
walk in the yard and what was grass is now like walking on Rice Krispies.
Of course everything has some moisture content but under these conditions
enough to promote roof mold everywhere. Maybe it has something to do with
the temp and humidity be the same most of the time - 95.

here is the result of typing 'black mold' into a Google web
tab search
http://www.google.com/search?hl=en&...G=Google+Search
Read 10 or 20 of the links.. you will be a black mold
expert... all molds or fungus's that are black are not
necessarily black mold.
Im not an expert on that. But for a time 4 years ago the HVAC
trade mags had a lot of articles on mold and the liabilities
and risks and causes, and how some contractors were being
taken down
for instance a leaking condensate drain creating conditions
for black mold to grow... some were no doubt bankrupted. It
was huge then... its quieted down a little now... but not a
lot.
Studying up yourself is what a person should do.
As soon as you admit that you know about black mold though,
and it can be shown that you were in a position to have seen
it....and didnt say anything to the owner, buyer or tennants
or whom ever... you become liable in many situations. If you
say something to the owner in writing he becomes liable...if
you keep it yourself he can claim later you didnt tell him and
you become liable. etc.
its touchy.
so we have 'ignorance' now.... the perfect cover. How
bad is it really? I dont know. Its probably been around for
thousands of years... but maybe not. Its worth looking
into.

It generally helps to know what the mess -is- before you start throwing
around terms like "very lethal." If I went around deciding that things were
very lethal without knowing what they are, they would consider me mad.

Thanks Phil but I ain't clicking those links no how. I have no black
mold. I don't wanna know what it looks like. What color is it? :-)
Nevermind, don't tell me.
I read what you said about :

Just curious, bleach?
Anyway, I was driving yesterday and I saw someone up power washing the
roof? Washing off all that pollution I guess.I never saw anyone actually
do it. I would think they washed away 5 years or so of life. Grit must
come off. If what they washed off is related to the black mold being
spoken of, must get tracked in the house to breed huh?

If you need a roof use any shingle with A/R. Timberline ultra's or Tamko.
This mold will NOT kill you

Not trying to be a wise guy. How do you know it works and please expand
on "OK".
======================
*Three ways to remove the stains from your roof after you have applied
the product.
1) ....
2) Use a pressure washer. Be very careful not to damage the shingles.
Keep tip 8-12 inch form shingles. 3) ....
======================
Maybe that dude I just mentioned in another article wasn't nuts? Using a
pressure washer at any distance from shingles just doesn't seem right to
me. Washing away years of service even with minor grit loss.

OK, it's alge, aka Gloeocapsa magma.
Read here. Found other articles saying the same thing when Googling
Gloeocapsa magma.

It will clean the roof, for how long the roof will stay clean varies on the
location. There is not much more to say after that,
