Mrs. Grossman's Sticker Factory

Sonoma County Single Ply Roof 

The Wedge Roofing team recently completed a commercial TPO Re-Roof project for Petaluma landmark company, Mrs. Grossman’s Stickers.

Sonoma County Commercial Roofing


Mrs. Grossman’s, which was founded in 1979, undoubtedly has a special place amongst many San Francisco Bay Area parents and children, as the stickers are a family favorite throughout the area.

As a father of three grown children, I fondly remember taking my kids to pick out their Mrs. Grossman stickers at local shops in Novato. Each son had an incredibly unique personality, and yet there seemed to always be a set of stickers that captivated their attention and freed their imagination.

Prior to the start of the project, I had the chance to tour the facilities with Mrs. Grossman’s son, Jason; now the President of the company. I learned that beyond the innovative and imaginative stickers the company releases, they are also highly focused on green production and produce labels for vineyards throughout the area.

"In the spirit of the free imagination Mrs. Grossman’s stands for, we at Wedge decided to re-imagine the project with help from some of Mrs. Grossman’s most popular stickers." Ralph Wedge

Wedge Roofing came through with flying colors… they were on time and prepared for every phase of the project and had the roof installed quickly and efficiently, even as sales consultants continued to sell cars, the Service Drive continued to function without a hitch, and customers continued having full access to the area.
