Roof Application
Skylite Construction LLC.
- Surface Preparation
- Loose gravel and dirt on existing built-up
roofs are removed by power brooming and vacuuming. If necessary, blistered and
saturated areas of the existing roof are removed. Sanblasting and /or priming
are applied to metal surfaces as required. Most existing roof surfaces are
primed prior to foaming.

- Polyurethane Foam Application
- The foam is applied as a liquid and rises in
a matter of seconds. Within minutes, the surface is firm enough to walk on.
The roof is sprayed to the design thickness. Flashings, penetrations, and
parapet walls are sprayed to form one monolithic blanket. Areas of ponding
water can be built up by spraying to facilitate positive drainage.

- Elastomeric Coating
- After curing of the foam surface, an
elastomeric, weather-resistant coating is applied. To ensure uniform coverage,
two or more coats using contrasting colors are applied. Elastomeric coatings
are designed to withstand water, ultraviolet radiation, and normal wear for
years of service. The use of a white top coat further reduces heat load and
thermal stresses in the structure.
