Tamko Building Products, LLC

Quality Products – A lot has changed since we introduced our first shingle in 1945, but one thing remains the same: our commitment to constantly moving the industry forward with quality building products, including residential and commercial roofing, waterproofing products, and cements and coatings.

Continuous Improvement – Our first Continuous Improvement program started in the 1980s based on the practices of famed statistician Dr. W. Edwards Deming. Since that time, TAMKO has incorporated LEAN manufacturing techniques and a robust Six Sigma program to further drive out variation and waste from our processes and products.

Vertical Integration – A vertically integrated company, owning and operating many of our own raw materials plants. Maintaining greater control over the entire manufacturing process allows us to better deliver consistent supply of products to our customers.
