Does your building need a Commercial Roof Replacement?

There comes a time in the life of every building when the roofing system will need to be repaired or replaced. If your current roofing system is older and beginning to experience chronic leaking or if the roof system is lacking insulation and not energy efficient, it may time to consider a commercial roof replacement instead of a repair.

Reasons to Replace your Failing Roof:

The cost of frequent maintenance or repair of structural damage due to leakage can be expensive. We can help advise whether your best solution is continuing to repair or complete a roof replacement by conducting a comprehensive roof evaluation. We will provide a detailed report showing the condition of the existing roof system, where weaknesses or failures are taking place, and a suggested course of action to provide you with the most cost effective means to prolong roof life, or when necessary, replace the roof.

Keeping the Facility Watertight

During construction we make sure to keep your building and occupants dry and safe from leaks and weather. This involves continuous weather monitoring both on site and in our offices and adequate temporary night seals at the end of each work day. We strive to ensure that your inventory, equipment, employees and clients all have a safe and dry environment to continue day-to-day activities. Safety is our top priority, both for your clients and personnel and for our on-site crewmen.
