Roof Maintenance and Services

At Peterson Roofing, we firmly believe in the importance of preventive maintenance for your building’s roofing system. Just like you wouldn’t purchase a new car and neglect regular oil changes, tire rotations, or tune-ups, your roof deserves the same attention. By opting for a roof maintenance/service contract with Peterson Roofing, you can proactively safeguard your building’s roof and prevent potential issues from arising. This proactive approach can potentially save you or your clients from facing substantial expenses and headaches in the future. So, what’s the next step once you’ve decided to move forward with yearly scheduled roof maintenance?

First and foremost, we conduct an in-depth roof survey to thoroughly assess the current condition of your roof. Based on our findings, we provide comprehensive recommendations to the owner regarding any necessary repairs required to ensure the roof is in a manageable state. This may entail tasks such as cleaning roof drains and removing debris, repairing damaged membranes, and sealing pipes and roof penetrations.

Once your roof is in a manageable condition, the dedicated staff at Peterson Roofing will conduct a thorough roof inspection twice a year as part of your preventative maintenance program. These inspections will include color pictures, capturing both pre and post-repair images of all the work carried out. Our typical maintenance program comprises the following services:

  • Ensure clean roof drainage with our expert service for drains, scuppers, and gutters. Optimal water flow guaranteed.

  • Remove roof ponding water by cleaning problem areas. Trust our expertise for a water-free and well-maintained roof.

  • Repair punctured membrane damage swiftly and effectively. Trust our expertise for a durable and protected roof.

  • Thoroughly inspect all flashings at penetrations, curbs, walls, pipes, and skylights. Rely on our expertise for comprehensive evaluation and maintenance.

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

A roof is a significant financial investment for building owners and protecting it is crucial. In California, roofs face harsh conditions such as hail, rain, lightning strikes, intense heat, seismic shifts, and foot traffic. However, the primary cause of roof failure in California is the absence of preventive maintenance. Safeguard your investment with proactive roof care.

A few areas to inspect common roof leaks

Pourable sealer pocket leaks are common in roofing systems with unusual or irregularly shaped penetrations.

These issues are often caused by building movements, materials, fatigue, trapped moisture, or improper installation.

It can be a combination of factors, including HVAC curved flashing, pitch, deficient cabinetry, and condensation issues.

Common issues include improper seals, clogs, corrosion problems, and downspout sizing issues.

A tear in the membrane can lead to water infiltration into the building and trap moisture in the roof system, promoting the growth of plants.
