There isn't a single answer to this question, as the cost of a roller garage door depends on several factors, including the size of the opening, quality of the door, slat size, colour, control system and the complexity of the installation.As a general guide, customers should budget from around £1,300 for a fully supplied and professionally installed single roller garage door, with larger double garage doors typically starting from around £1,600.For the most cost-effective option, white is normally the least expensive colour, while a 55mm insulated aluminium slat is generally suitable for standard single garage openings up to approximately 2500mm wide. Larger openings will require a more substantial 77mm slat.The choice of control system can also affect the price. A straightforward hold-to-run system is generally less expensive than a system incorporating a safety edge, which can automatically detect an obstruction when the door is closing.Installation requirements can make a difference too. Every garage is slightly different, and factors such as the available headroom, fixing surfaces, electrical supply, access and whether the door is fitted between or behind the opening can influence the final cost.It is also worth remembering that roller garage doors vary considerably in quality, so comparing quotations purely on price can be misleading. The specification of the door, motor, controls, safety equipment and installation should all be considered.For this reason, Garrolux offers a free, no-obligation home survey.
