Madsen Roof Company maximizes the
return on roofing system investments
by subscribing to the mantra: "Every
commercial building envelope demands
a unique roof system." For architecturally
complicated roofs that are susceptible
to volatile weather conditions, or
failing roof systems compromising
thriving businesses, Madsen Roof Company
often recommends Sprayed Polyurethane
Foam (SPF) commercial roofing systems.
Capable of being applied to the most
commercial roofs and compromising
protrusions, polyurethane foam is
applied as a liquid, creating a single
membrane that covers the entire roof
— free of leak-causing seams
and joints.
Sprayed Polyurethane Foam systems
have a high strength-to-weight ratio.
In fact, foam roofing typically weighs
approximately 50 lbs. PSF, compared
to BUR's 700 lbs. PSF and ballasted
single-ply at 100 lbs. PSF.
Satisfying California's
Title 24 requirements, sprayed
polyurethane foam roofing has an R-value
of 7.14 per inch thickness, providing
even more thermal resistance with
less materials demanded by traditional
membranes. In fact, foam roofing is
known to yield up to 30% in energy
savings over traditional alternatives.
According to the Roof Coatings Manufactures
Association (RCMA), polyurethane foam
roofing investments can generally
be recovered in just five years of
use — through energy savings
alone!
| Advantages
of a Sprayed Polyurethane
Foam System |
| 1. Eliminates need
for tear-off and business
disruptions for roof
replacement projects.
|
| 2. Integrates waterproofing
of roofing system
with entire building
envelope. |
| 3. Affords a long-term
roof system investment
with minimal maintenance
and UV degradation
and weathering. |
| 4. Sophisticated
cool roof system improving
building's energy
efficiency. |
| 5. California
Title 24 Compliant |

Commercial installation of SPF roofs
demand experienced roofing professionals
that understand the properties of
this unique roofing material. Applied
by spraying a two-part liquid onto
a suitable substrate, SPF roofing
quickly expands and hardens to form
sophisticated closed-cell polyurethane
foam.
Generally applied between one and
four inches, the thickness of the
foam layer depends on the environment
(temperatures, winds, etc.), the slope
of the roof systems and supporting
drainage systems. Flexible to new
roofs or commercial roof replacement
projects (including BUR systems),
SPF roof systems are amiable to most
subtrates including an existing roof
membrane, or most insulation materials.
It's important to protect foam roofing
from the destructive effects of moisture
and of course the sun's UV radiation.
Additionally, some foam systems have
a high flammability, for which such
protection should be considered in
the planning and installation.
Acrylic coatings are known to be
the most affordable, however, over
the life of the SPF roof system, an
additional coat may be necessary sometimes
as much as every decade depending
on the climate. Slightly more expensive,
polyurethane, silicone, and mineral
(e.g. sand) coatings are also available
and offer more durability, functionality,
and a longer system lifecycle.
