A healthy roof is vital to building safety, durability of assets, and mitigates operational risks. Water impacts commercial real estate and large warehouses in its many forms. Snow and ice increase load on roofs, which can lead to collapse. Clean drains are essential to avoiding backups and pooling which can lead to damage inside and outside a facility. GRS Roof Watch, powered by Divirod, monitors these issues for you.
