IMPENETRABLE ROOFING AND SIDING
Jones and Gutterman shared a concern for fire resistance and durability
when they were choosing the siding and roof. “Standing seam metal roof-
ing was a no-brainer,” says Jones. While they selected the Fabral roofing
for its exceptional resilience, they also designed the project so that no
penetrations would go through the product.
“There are no hollow soffits on the houses because sparks can come in
through soffits,” Jones explains. “We also vented everything out through
the sides of the houses through the gables. The [energy recovery ventila-
tion], plumbing, exhaust fans and vents all go out through the walls.”
Jones did this partly because of the heavy snow loads the houses will
bear. With no penetrations on the 9:12-pitch roofs, the snow slides off the
roof, and what snow remains will not infiltrate the house. The impenetra-
ble roof also provides protection against embers should a forest fire occur.
For a similar reason, Jones opted for James Hardie fiber cement sid-
ing and trim. The vertical board-and-batten product is fire resistant and
durable, while its solid color qualities and dimensional stability elimi-
nates cracking or peeling. James Hardie offers the siding prefinished with
ColorPlus technology, which gave Jones 25 colors to choose from and
