The garage we take for granted very likely stores thousands of dollars worth of tools and household belongings, not to mention your automobiles. Yet this space is typically rather easy for intruders to penetrate. Garage security can be greatly improved by installing a modern garage door opener that features rotating digital codes, which can foil even the most tech-savvy prowlers.
“Every spring on every garage door will break,” says Jim Rice, owner of Broad Ripple Overhead Doors & Openers in Indianapolis. “After so many thousand times up and down, it gets metal fatigue and snaps. At least once a year, you should disconnect the garage door springs and lift the door up manually to see how well it’s balanced. Unless you hear metal screeching or something breaks, you don’t need us.”

The history of the garage door could date back to 450 BC when chariots were stored in gatehouses, but in the U.S. it arose around the start of the 20th century. As early as 1902, American manufacturers—including Cornell Iron Works—published catalogs featuring a "float over door." Evidence of an upward-lifting garage door can be found in a catalog in 1906.
Roller doors ("Sheet Doors"-USA) are usually constructed of corrugated steel. They evolved from cover window and door coverings. Other materials can be used (e.g.; transparent corrugated fibreglass) where strong impact resistance is not required. Corrugations give the door strength against impacts. A typical single car garage roller door has a preloaded spring inside the rolling mechanism. The spring reduces the effort required to open the door. Larger roller doors in commercial premises are not sprung (except USA) and use a manual pulley and chain system or a geared motor to raise and lower (roll up and roll down) the door. Roller doors cannot be effectively insulated.
