Who should have maintenance on their roof.

Everyone! Regardless of the type of roof or the condition of your roof we can provide maintenance and repair services to address all of a building owner’s roofing needs promptly.

When should maintenance be performed on a commercial roof.

The National Roofing Contractors Association (NRCA) recommends maintenance and repair be performed at least twice a year. More importantly before and after severe weather seasons such as a winter in the Northern United States. These inspections are to clean the roof system of natural debris, clear all gutters and waterways, and assess vulnerable points in the roof system to ensure that there is no degradation that can leak in the future.

In addition to scheduled maintenance twice a year it’s important to have a contractor inspect and perform needed repairs after severe weather such as high winds, hail, and severe storms. These inspections are to clear any debris such as metal from HVAC units or other penetrations. These inspections ensure that there is no damage to the roof system, flashings, copings, and other units.

Commercial Roof Maintenance Contracts


Many material manufacturers have warranties that require a building owner to have inspections periodically and maintenance performed regularly on their roofing systems.  A maintenance contract is an easy way for building owners and managers to ensure their commercial roof remains under warranty and in good condition while staying in their budget.

A maintenance contract between a building owner/manager and contractor allow you to have ongoing maintenance performed over the roof system’s life cycle. There are three main types of maintenance contract options:

  1. A contract that requires the contractors to visit the building/property regularly for gutter and drain cleaning along with a visual inspection and report.
  2. A contract that requires gutter and drain cleaning, debris removal, along with a visual inspection, small general repairs, and a report.
  3.  A contract that requires gutter and drain cleaning, debris removal, along with a full inspection, medium general repairs, roof survey and a report.

A maintenance contract is a great way to keep your building/property in good shape while holding your contractor accountable for the performance of their work.
