Roof Maintenance and Services

At Peterson Roofing, we are firm believers in preventive maintenance of your buildings roofing system. You would not buy a new car and never have the oil changed, the tires rotated, or just have a simple tune up. Well your roof is no different. When you have a roof maintenance/service contract with Peterson Roofing, you can rest assured that you are being proactive with your buildings roof and not waiting for issues to arise. This in reality could save you or your client untold amounts of money and headaches in the future. So what needs to happen now that you have made the decision to move forward with yearly scheduled roof maintenance? First, we need to do an in depth roof survey to ascertain the actual condition of the roof and make all recommendations to the owner as to any repairs that are needed to bring the roof to a manageable condition. This could include cleaning all roof drains and debris from the roof, repairing any damaged membrane, and sealing pipes and roof penetrations.

Once we have your roof in a manageable condition, the Peterson Roofing staff will provide you with a comprehensive roof inspection twice a year as part of your preventative maintenance program. It will contain color pictures of all repairs both pre and post repair. A typical maintenance program involves the following services:

  • Clean all Roof Drains, Scuppers, and Gutters

  • Clean Roof Areas where Ponding Water Accumulates

  • Repair all membrane damage from punctures

  • Inspection of all Flashings at penetrations and curbs, including Walls, Pipes, and Skylights

Ready to schedule a time for your roof survey and set your roof maintenance on autopilot then just call our office at (888)596-4889 or fill out the contact form on this page and our friendly staff will set a day and time for us to come to your facility to get you started.



A well-maintained commercial roof is the best way to protect the entire building envelope from storm and water damage.

A roof is one of the largest financial investments a building owner can make and is something that is easy to protect. Roofs in California receive extreme conditions like hail, rain, lightning, strikes, fierce heat, seismic shifts, foot traffic. However, the biggest reason roofs fail in California is due to a lack of preventive maintenance.
