Safety First

Read this information before starting your project.

Installing renewable energy equipment often involves climbing ladders, working on roofs or digging trenches. All these improvements can pose a risk that can result in serious injury or death.

When working on a roof we recommend a harness securely attached to the roof. Everyone working on the roof should be wearing a harness at all times. Ladders should extend three feet above the roof. A temporary board should be installed towards the edge of the roof to catch tools and provide a safety catch in case someone looses their footing and slides down the roof. The board should not be a replacement for wearing a harness, however.

If you are unsure of your capabilities contact a contractor to perform the work.
