St. Augustine Historic Preservation Board


As per request an inspection was made of entire roof area
and related flashings of the Government House on August 5, 1982.
It was observed that there are two types of roofing systems pre-
sent. The majority of the roof area is covered by a Ludowice-
Celadon flat clay tile that is a discontinued line. It is nailed
over a heavy 40-45# felt underlayment with copper roofing nails
into 2 x 6 tongue and groove sheathing.
The flat or low sloped areas are covered by a coal-tar
pitch built-up slag surfaced roof.
All flashing systems are copper.


VISUAL OBSERVATION


The tile roof appeared to be in relatively good shape. Due
to the pitch of the roof and the lack of protrusions, traffic
has been minimal, which is indicated by the lack of the usual
cracked or broken tile. Thanks to the copper nails and the ex-
cellent deck system the attachment of the tile is still very
secure. The copper valley was badly worn from traffic and indi-
cations of much patching was observed.
One area of tile that needs immediate attention is the small
section of porch roof that faces King Street on the east wing.
The roof has a pitch of 1" in 12" which is too flat for tile
even though it was installed over a built up underlayment. This
is evident by the vegetation that is growing between the tile.


BUILT UP ROOF


The built up roof was found to be in a completely deterior-
ated condition. There are many areas of exposed felt, blisters,
and delamination of plies.
The base flashing system at juncture of roof and verticle
surfaces has completely deteriorated and provides little or no






moisture protection.


THE FLASHING SYSTEM


Being copper, the metal flashings system still is sound,
with the exception of the valleys. Due to traffic and contraction
and expansion the valleys have evidence of many crimps, pinholes,
and deterioration.


ROOF DRAINAGE


The entire roof drainage system of this building is either
hindered, completely stopped up or nonfunctional. 80% of the water
leaving the roof of the building has had to seek a new avenue of
evacuation other than the one originally intended. All the gutters
were completely full of water or debris. All collector heads were
completely stopped up forcing water back thru the scuppers causing
a buildup of water on roof to reach 8" to 10" in depth. Being
copper the drainage systems are structurally sound but suffer
from neglect. Much of the stoppage is resulting from the growth
of algae.


RECOMMENDATIONS:


I recommend the following:


BUILT UP ROOFING


I think the most economically feasible way to approach this
area is with a recover system that is guaranteed by one of the
major roofing manufacturers such as the Owens Corning R-303-ICD
systems. These are smooth coated systems which will result in
easier maintenance.


TILE ROOF


Due to the good condition of the majority of the tile roof I
think a patch and repair situation is the most feasable. I recommend






the following:


1) Remove tile from low-sloped porch roof on south side and
install a smooth coated built-up roof system. Since original tile
is no longer available, these tiles can be used to repair damaged
tile on remainder of roof.
2) Rework copper valleys by completely removing metal and related
tile, installing new underlayment, install new copper valleys
and reinstall adjoining tile.
3) Carefully check entire roof area, reinstalling loose tile and
replacing cracked or broken tile.


FLASHING SYSTEM


Completely check all chimney flashings, metal crickets, wall
flashings, baseflashings, pitch pockets and any roof related
flashing. Any joints that show signs of splitting or separations
should be re-soldered or tightened in an acceptable manner.


ROOF DRAINAGE


Clean all gutters and downspouts, collector heads, and conduc-
tors, roof drains and scuppers. Re-solder or caulk all splits or
separations. Replace any crimped or damaged metal that will re-
strict water flow.


I think a complete roof maintenance program would be one of the
most beneficial factors in maintaining a good water tight condition
on this structure and extending the life of this roof. All the prob-
lems observed could have been prevented if caught in their early
stages of their deterioration and kept interior damage to a minimum.
Since this type of roof maintenance will be mostly a "labor only"
situation I think the best economical approach would be cost plus.
