PPE is more than a hard hat and safety glasses.

From Type 1 vs Type 2 hard hats to respirators, gloves, visibility gear, footwear, and heat protection, understanding PPE means understanding the hazards present on the job.

We put together a comprehensive guide to Personal Protective Equipment for roofing and construction professionals.

Personal Protective Equipment is the last line of defense, and the best kind of PPE are the ones workers consistently wear.

In observance of Memorial Day, Big Rock Supply will be closed on Monday, May 25, 2026.

Memorial Day is a time to honor and remember the men and women who made the ultimate sacrifice in service to our country. As we take time with family, friends, and our communities, we also honor those whose courage and sacrifice made those moments possible.

We will resume normal business hours on Tuesday, May 26.

Wishing everyone a safe and meaningful Memorial Day.
