Things To Know [FAQ]:

What Is A Roof Vent?

A roof vent allows ventilation for crawl spaces and attics, and protects roofs from heat damage and condensation. Unventilated roofs are at risk for untimely shingle damage and pose health risks for inhabitants of the structure. A properly ventilated roof greatly lessens the likelihood of encountering mold, ice dams, and significantly decreases energy expenditures.

What Are Acme Cone’s Vents Made From?

Our roof vent flashings are built from PVC [polyvinyl chloride] and TPO [thermoplastic polyolefin]. We hand-inspect each and every vent and flashing built before we send them to customers to ensure success on any project.

What Types of Vents Does Acme Cone Produce?

We have several different types of roof flashings available for any problem you may encounter during a roofing project: 

  • Gravity Vents
  • Breather Vents
  • Turbine Vents
