The Sangre De Cristo Center was a 12,000 sq. foot existing tar and gravel roof with numerous leaks. The main cause of the leaks was lack of slope. The roof had interior drains with poor drainage. After significant rains and snows, water would pond in some cased over 2” thick.
Southwest Spray Foam was contracted to provide a new spray polyurethane roof system. For was attractive for three main reasons:
- Southwest Spray foam can provide slope by building up the thickness of the foam. When the roof was complete the minimum thickness was 2” at the drains and 6” on the ridges. The key to any roof is proper drainage. By creating drainage the roof will continue to perform for many years to come.
- Insulation was definitely needed. The added foam will provide an additional R-22 average. This will make the conditioned warmer in the winter and cooler in the summer.
- Compared to other roof systems, spray foam was less expensive, and faster to install. The whole job was done in two set ups, taking about 4 days per set up.
