According to a recent article in SprayFoam magazine, spray foam provides a much better roof system than bituminous membrane roofing when it comes to withstanding storm damage.

Spray foam provides a continous surface wth no edges, seams or joints that is self adhering, protects from water, and resists high winds, missile damage, and penetration.

Here’s a summary of some of the differences:

	Membrane Roofing	SPF Roofing
Structure
Assembly	Overhangs and overlaps seams and joints	Continuous surface with no edges, seams, or joints
Flashings	Attached flashings	Self-flashing
Attachment	Secured to deck with fasteners	Self adhering (no fasteners)
Weather Effects
Projectiles	Subject to damage and penetration	Resists missile damage and penetration
Wind	Can lift off or peel under high wind	Grips building wall to resist high winds
Water	Peeling exposes interior to water	Continuous surface protects from water
