How Do You Pick A Commercial Roofing System?

Restore Your Roof
Discover what restoring your roof can do for your property.
Replace it - Low Slope
Some roofs have reached the point where repair or restoration are no longer options, replacement is sometimes the only viable option.
COMMERCIAL RE-ROOFING - TEAR OFF AND RECOVERS
Re-roofing is the process of installing a new roof when a roofing system fails. Roofing system failures can be caused by several factors, including age, severe weather, poor workmanship, defective materials, improper specification of a roofing system, abuse, and failure to maintain the roof via inspections.
COMMERCIAL ROOF REPAIR
Repair is a process where an existing roofing system has additions and adjustments made to it, such as caulking, re-coating and repairing penetration to fix leaks in the roofing system. We offer repairs for Homeowners, Real estate Agents and Insurance claims.
COMMERCIAL RESTORATION
Restoration involves the major repair of the roof system, including the repair of all penetrations and resurfacing of the roof to restore it to serviceable condition. The opportunity to perform restoration work normally exists two or three years prior to the roof’s end of its life cycle and before significant damage occurs. The cost of restoration is typically one half of the cost of re-roofing. We employ a team that has specialty training to be able to identify and correct major deficiencies in roof systems prior to replacement. This process can include coatings, re-flashings and modern design modifications.
COMMERCIAL ROOF MAINTENANCE
Maintenance involves the physical inspection of an existing roofing system to determine its current condition, detect weakness and failures and identify any potential future problems. Through a program of regularly scheduled annual or semiannual inspections, the company's technicians assist owners in protecting their roofing investments by seeking to identify damage in its early stages. Early detection of leaks and roof system failures make it possible for the company to repair and extend the life of a roof system through repair or restoration, which is significantly less expensive and time consuming than re-roofing.
