The 1980s was a tough decade as inflation took a toll on contractors. As many contractors struggled to stay afloat, roofing over existing systems became common even though the approach reduced the roof life. The period saw many large rubber-roofing manufacturers increasing their warranties, continued improvement in the quality of roofing products and methods of installation, and increased popularity in aesthetics. The U.S. government increased its involvement in the construction industry regulations through agencies such as EPA, DOT, and OSHA. More laws were introduced to protect the customers, construction workers, and conserve the environment. During the same period, many villages and cities started to require contractors to abide by building codes, Iowa Roofing Company embraced and became practiced with these sweeping new regulations.
As a continuation of the previous decade, the 1990s saw roofing materials and specifications from manufacturers improve. New concepts such as ballasted, single ply systems, fully adhered to mechanically attached became popular in the market. The insulation R-value increased even further to a new value of 20. The new roof systems had more penetrations to the top, including exhaust systems, satellite dishes, plumbing pipes and roof drains, HVAC units, expansion joints, roof deck pavers, grease traps, green roofs, and observation decks.
