• How to Avoid Mold, Rotting & Rust

    Proper ventilation and drainage are crucial for a healthy structure. Improper or insufficient ventilation of a roof and attic space can lead to a laundry list of potential issues, including: 




    • Failure to properly release built up heat, which can cause ice damming in northern climates and undue stress on HVAC systems in the south  



    • Moisture buildup that can cause rot, mold, rust, and more undesirable consequences 

    At Keene Building Products, we create spaces. From the need to provide proper drainage and ventilation under a cedar roof to venting the air from unconditioned attic space. KEENE provides the space that provides the solution.
