Siding over Asbestos
Vinyl siding retrofit over asbestos
This is a recommendation from the Vinyl Siding Institute after
discussions with Federal EPA officials. Because local
regulations supersede federal regulations, local EPA officials
should be contacted in the area where the work is being done.
The most desirable practice is not to disturb the existing
siding on the home. Apply sheathing over the existing
asbestos siding and then apply vinyl siding over the top of the
sheathing. The sheathing will serve to flatten the wall and also
retain any breakage of the cement asbestos siding. Nails
should be long enough to penetrate the sheathing, existing
asbestos siding and into the wall studs.
If there is a need to level or flatten a wall, apply furring strips
over sheathing.
In the case where the homeowner wants the existing cement
asbestos siding removed completely, removal should be done
by a professionally trained asbestos removal crew.
Please note that some jurisdictions require all asbestos
removal to be performed by a trained asbestos removal crew.
Historic Restoration
Vinyl Siding Institute recommended guidelines
If a building is in an historic area or has been designated an
historic building, be certain that approval for the use of vinyl
siding has been obtained from the local historic society. This
applies to building additions as well.
Before proceeding to re-side an historic building, the building
should be examined for moisture, insect infestation, structural
defects and other problems which may be present. These
problems should be addressed and the building pronounced
“healthy” before re-siding with any material.
Do not damage or remove the original siding. If at all possible,
do not alter the original structure so that the application of
vinyl siding is reversible (i.e. the original would remain intact
and some time in the future, if desired, the vinyl siding could
be removed). Exception: “In cases where a non-historic
artificial siding has been applied to a building, the removal of
such a siding before the application of vinyl siding would, in
most cases, be acceptable.” (Preservation Briefs, Number 8 -
U.S. Dept. of the Interior - 1984)
