Avoid Voiding Your Roof Warranty: Why Maintenance Matters
Your commercial roof includes a warranty that safeguards your investment—but it’s crucial to understand the terms and conditions. Just as a car warranty won’t cover damage if you neglect oil changes, a roof warranty also requires basic maintenance to remain valid. Additionally, there may be situations that your warranty might not cover at all.
Roof Inspections Are Key
Most commercial roof warranties require regular inspections—some even mandate the timing. For example, an annual or semi-annual inspection may need to take place in the spring to assess any damage from winter weather. These inspections are common sense: they help identify potential issues early, extend the life of your roofing system, and ensure your building remains protected.
Don’t Overlook the Fine Print of Your Commercial Roof Warranty
Some warranty requirements are more subtle. For example, areas with high foot traffic may need to be equipped with walk pads. Without them, repeated foot traffic can damage the membrane. Walk pads not only preserve your roof system but also enhance safety for anyone accessing the roof.
Know the Limits of Coverage
Roof warranties also have limitations. For example, most warranties depend on your roof being designed for a specific wind speed—let’s say 80 MPH. If your building is in an area prone to hurricane-force winds, you may need a higher-spec system to stay protected under warranty.
In addition, many warranties do not cover damage caused by:
- Rodents
- Hail
- Acids or hazardous chemicals
- Unauthorized repairs or alterations
Roof Maintenance Matters
Most warranties include a care and maintenance guide, but your facility team may not always be adequately equipped to follow it properly. That’s where a qualified service and maintenance partner comes in. By collaborating with a dedicated commercial roofing maintenance team, you can ensure warranty compliance and extend the life of your roof.
Your warranty is extremely valuable—but only if you adhere to the maintenance requirements. We’re here to assist you. If you have questions about your roof warranty or wish to schedule an inspection or service, click here to get in touch with us.




Greenwood Industries’ longstanding reputation for excellence in commercial roofing extends to GRS’s work on large-scale public facilities. A prime example is Magazine Beach in Cambridge. The historic brick building, which houses the pool’s facilities, required a new roof in preparation for the busy summer season. GRS installed a durable EPDM roofing system, ensuring the structure is well-protected and ready to serve the community.
Sawmill Restoration: Upon arrival, the GRS team discovered that the historic wooden sawmill was home to a colony of baby bats. The project was temporarily paused to allow the bats to mature and leave the building safely. Once they departed, GRS completed the restoration with a beautiful cedar shake roof, preserving the sawmill’s historic character.
GRS’s work spans every corner of Massachusetts, including offshore projects like Peddocks Island in Boston Harbor. The team replaced the roof on the island’s historic chapel—a project that required unique logistics, including an amphibious landing to transport materials and equipment onto the beach. This successful re-roofing not only preserved the chapel but also showcased GRS’s adaptability to challenging work environments. The team is now preparing for additional projects on the Boston Harbor Islands.
