Why are you removing the shingles? Did they need to be replaced anyway?

Hello Codescab,

   It seems each state, and even county have different regulations
regarding asbestos disposal. The majority of the regulations appear to
indicate that non-friable shingles (not crumbling or torn) can be
discarded in a dump. Other states require a special location of the
dump. Different areas in California have  varying disposal regulations
as well. I'm afraid you wil have to determine the ondition of your
shingles and call some of the numbers I have posted for your area.I'd
certainly want to call and find out for myself if it is legal to
discard your shingles in a dumpsite. A hazmat team is not likely
needed unless your shingles are friable.

  When asbestos shingles are intact, the asbestos is bound to the
cement, asphalt, or vinyl medium, rendering the asbestos non-harmful;
this is why non-friable shingles are relatively safe, and pulverized,
shredded or torn shingles are more dangerous.

   ?Non-friable asbestos-containing material (ACM) is typically bound
up with cement, vinyl, asphalt, or some other type of hardening
binder. Some examples of non-friable asbestos building products are
transite (cement) siding, vinyl asbestos floor tiles, and asphalt
roofing shingles. Non-friable materials are not regulated. Some
non-friable asbestos materials are still being manufactured. Note:
non-friable ACM can become RACM if it is pulverized or turned to dust
during remodel and/or repair activities.  Non-friable ACM can also
become RACM if it is burned.?

?When disturbed, friable RACM asbestos crumbles into a dust of
microscopic fibers which can remain in the air for long periods of
time. If inhaled, they pose a serious health threat as asbestos fibers
can become permanently lodged in body tissues.?

   For California: 'There, you will find helpful information about
many subjects, some of which aren?t under DTSC?s jurisdiction
(asbestos abatement, sewage releases, and more).  If you can?t find
what you are looking for, call our Regulatory Assistance Officers.  In
California, call 800-72TOXIC (800-728-6942).  If you are outside of
California, you can still contact a live person.  Those Hazardous
Substances Scientists (Noel, Andre, and Gloria) handle a few hundred
calls per week, but you can expect to hear back from them in a day or
two.  Or, if you prefer, send an email."

   "The homeowner should use the following guidelines in choosing a qualified
? Check to see if the contractor is licensed by the California
Contractors State License Board and registered with
the California Department of Industrial Relations, Division of
Occupational Safety and Health (Cal/OSHA) for
doing asbestos work.
? Be aware that some contractors may remove material incorrectly and
still charge a substantial fee.
? Require references from the contractor and check them to see if the
contractors work is satisfactory.
? Require the contractor to specify his safety procedures in writing.
The homeowner may expect to pay three times as much for the removal
than if asbestos were not present. For a small job, the cost may be
more than three times the normal cost, since it is expensive for a
contractor to set up all the necessary safety equipment. Consider
hiring a certified asbestos consultant to review safety procedures and
oversee the performance of the contractor."

For information concerning the identification and abatement of
asbestos hazards in the home, and on the
asbestos content of certain consumer products, call the EPA Asbestos Hotline at:
Telephone: (800) 368-5888

  "Can I remove asbestos-containing materials myself?

    In California, the California Air Resources Board and the Regional
Air Quality Management Districts or Local Air Pollution Control
Districts regulate the removal of Asbestos-Containing Materials, or
ACM. For a general background on asbestos-containing material, follow
this link to the California Air Resources Control Board's Asbestos web
pages. Some districts allow homeowners to remove small amounts of ACM
from their own residences without a permit as long as they follow
correct practices. For larger amounts, a certified asbestos removal
contractor is required. Call your Regional Air Quality Management
District (AQMD) for information on rules applicable to your area."

California Air District Resource Directory
COntact Information

Page 2 of this document has phone numbers to local district offices:

   ?The transite material can be worked with in a safe manner with
each state having their own guidelines and regulations. The EPA also
have their rules. At a minimum, the material being worked with should
be kept wet during work and removal, the nails extracted from the
material and the product lowered to the ground for continued
processing/handling. Disposal of all this material remains a matter to
be governed by each individual location and state and most often the
disposal sites are also regulated.?

   ?Even if asbestos shingles are on your home, if they are in good
condition and left undisturbed, they are usually NOT a serious
problem. The mere presence of asbestos in a home or a building is not
hazardous. The danger is that asbestos materials may become damaged
over time and become airborne. Damaged asbestos may release asbestos
fibers and become a health hazard.?

   Except for disposal, these rules, however, do not apply to houses
of four families or less. An owner of a single-family residence can
remove and dispose of asbestos cement shingles without being subject
to federal restrictions that apply to contractors. There will most
likely be state and local ordinances governing asbestos shingles and
their removal. These may prohibit removal and disposal by anyone other
than a licensed and certified asbestos contractor.  Your state's regs
may apply to homeowners - check - if they do then:
State permits are often required of contractors for the removal of
asbestos containing asphalt/ bituminous roofing products and asbestos
cement shingles/panels under the following conditions:
?	160 square feet of friable asbestos containing roofing materials
will be removed.
?	5580 square feet of nonfriable asbestos containing materials such as
built up roofing will be removed using a rotating blade cutter.
?	160 square feet of nonfriable asbestos/cement roofing products will
be removed using techniques that will create friable asbestos
containing material (ACM).
NOTE: Friable ACM means the material has been crumbled, pulverized,
reduced to powder, or has otherwise deteriorated so that the asbestos
is no longer likely to be bound within its matrix.
Permits must usually be obtained  ten (10)working days prior to
staring the removal of regulated asbestos containing roofing material.
Within 45 calendar days from the completion date stated on the permit,
the owner or his representative must submit a completed Waste Shipment
record to the state or county agency.
Before removing any asbestos-containing material from your house, you
should check with your local government authority; usually the county
health department will know. ?
LEAVE IT ALONE! Disturbing it may create a health hazard where none
existed before. Read this page before you have any asbestos material
inspected, removed, or repaired.
Asbestos cement roofing, shingles and siding products are not likely
to release asbestos fibers unless sawed, drilled, or cut.?
?Normally, roofing and flooring contractors are exempt from state and
local licensing requirements because they do not perform any other
asbestos-correction work. BUT if they do remove asbestos they WILL be
subject to the requirements! Call 1-800-USA-ROOF for names of
qualified roofing contractors in your area. (Illinois residents call

??  Keep the material wet at all times. A low pressure garden sprayer
adjusted to "mist" can be used. Water helps keep asbestos fibers from
becoming airborne.
?  Avoid tearing, ripping, chipping, cutting, or grinding
asbestos-containing materials. These actions create new surfaces where
there is the greatest potential for release of asbestos fibers.
?  Do not throw or drop asbestos-containing roofing or siding
materials to the ground. Instead lower them carefully to prevent
breakage and dispersal.
?  Place asbestos waste in polyethylene bags at least 6 millimeters
(6-mil) in thickness, or wrap it in two layers of 6-mil polyethylene
sheeting sealed with tape. Additional water may be added to ensure
thorough wetting, but do not add so much that the bag bursts when
?  Debris already on the ground should be wet and either collected
manually or shoveled up and bagged for disposal. These residual
materials can be pulverized and further dispersed by repeated
mechanical action and are potential sources for generating airborne
asbestos fibers.
?  Containers (bag, drums, wrapped components) should be labeled with
?  Store material in a secure area until it can be taken to a
landfill. Materials should be transported in a way that keeps them
from leaking, spilling or blowing off the transporting vehicle.
?  You may obtain written approval for disposal by writing to the
Asbestos Section, Bureau of Air Quality, SCDHEC, 2600 Bull Street,
Columbia, SC 29201. State the address of the residence from which the
material was removed, a brief description (for example, cement-like
tiles, asphaltic shingles, etc.), the volume of waste in cubic yards
or the area in square feet of the material removed, and the name and
location of the landfill to be used. Contact the landfill directly to
ensure it will accept the material. If you do not know of a landfill,
contact our office at (803) 898-4123 for assistance.
?  DO NOT BURN any asbestos-containing or asbestos-contaminated debris.?

  Asphalt shingle roof replacement can generate waste at rates
of at least 2 to 5 pounds per square foot of roof area.

  Generation rates vary by the number of layers and the type of

The Asphalt Shingle?s Components

Asphalt shingles are made from four basic materials:
% by weight
??fiberglass or cellulose felt backing: 2-15%
??asphalt cement: 19-36%
(on a fiberglass matt base: 19-22%)
(on a cellulose felt base: 30-36%)
??mineral granules (aggregate): 20-38%
??mineral filler/stabilizer: 8-40%
The asphalt cement and aggregate content of shingle waste make
recycled shingles a desirable additive or feedstock substitute in
pavement materials. Page 2 of this document contains a chart with
states that recycle old asbestos shingles.
