How much is TAMKO worth?

TAMKO Building Products is a privately held company, so its exact market value or net worth is not publicly disclosed like publicly traded companies such as Owens Corning or GAF's parent, but estimates can be made from revenue and industry comparisons. TAMKO, founded in 1944 in Joplin, Missouri by E.L. Craig and family-owned by the Humphreys family, is one of the largest privately owned roofing manufacturers in the US. Industry estimates put TAMKO's annual revenue at approximately 1 to 1.5 billion dollars from shingles and building products, with manufacturing plants in Missouri, Maryland, West Virginia, and Texas. Private building materials companies typically trade at 0.8 to 1.5 times annual revenue depending on profitability and market conditions, which would value TAMKO at roughly 800 million to 2 billion dollars, though some estimates place it higher due to its large market share in central US and Texas. TAMKO's worth includes its manufacturing plants, real estate, brand, and inventory, plus significant land holdings in Joplin. The Humphreys family that owns TAMKO is considered billionaire family in Missouri. Because TAMKO is private, it does not file public 10-K, so precise valuation is only known to family and banks. For comparison, publicly traded Owens Corning has market cap around 15 to 18 billion, and GAF's parent Standard Industries is valued at over 10 billion, so TAMKO is smaller but still substantial. If TAMKO were to be sold, industry analysts estimate it could fetch over 1.5 billion.
