The modern roof drain is designed to drain off rain water in the most effective manner possible while maintaining an aesthetic appeal because in many instances it is placed in full view of the public.

Through the years, Smith has attempted to satisfy both the artistic eye of the architect and the calculating mind of the engineer, concluding the properly designed roof drain must have the following features:

• Pleasing dome shape with a low profile and adequate free drainage area
• Corrosion-resisting dome material
• Effective debris protection
• Overflow drainage to allow drainage during debris build-up
• Gravel stop
• Positive Flashing Clamp
• Seepage control channels
• Sump designed to minimize air entrapment
• Flexibility to meet all construction requirements
