Commercial Roofing

Commercial Roof Types
Alpine Roofing Co., Inc. has the resources and equipment to complete roofing projects for office buildings, industrial, retail/restaurant, and multi-family. Many commercial roofs are low-sloped.  A roof that has a pitch under 2/12 is considered a low-sloped roof also known as a flat roof.  Flat roofs are typically covered with a type of membrane material that helps shed water from a slight inclination.  The water on the roof will either filter into a gutter system or a rainwater drainage system that drains directly in to the ground, keeping the walls and foundation dry.

Maintenance after your roof replacement
It is necessary to maintain your roof and keep debris off of the roof and out of the roof draining system to comply with your manufacturer’s warranty.  Maintaining a flat roof can be difficult at times because water will penetrate the various types of coverings and travel a long way before causing visible damage or leaking into a building.  Also, the maintenance of drains, scuppers, gutters, and downspouts is a very important step in maintaining a flat roof because gravel, leaves and debris can collect and prevent water from draining off the roof.  This causes a pressure head of water which will force the water into the smallest hole or crack.  In Colorado’s climate, ponding water can freeze breaking up the roof’s surface as it expands while it freezes creating cracks that melted water will penetrate.
