Metal roofing should not be hand-installed, because it demands that roofing screws be separated by no more than two feet. Driving this number of roofing screws by hand would quickly exhaust the hand and arm strength of the roofing crew, and relying on the rechargeable roofing screw guns now available would mean to switch to fresh batteries at hourly intervals. Because most rechargeable roofing screw gun batteries require a charging time of one hours, each roofing crew member would need four batteries to complete an eight hour shift!

One solution would be to use an electrically powered roofing screw gun which can operate without interruption for an entire day. Most of these screw guns are manufactured with adjustable power levels, enabling their users to select just the right amount of force to use when installing the roofing screws.

Roofing screws which are driven too deeply into a roof can either damage the roof itself or have their heaps snapped off, making them very difficult to remove. The disadvantage of using an electrically powered roofing screw gun is that it rewires the use of a long extension cord, which can be a hazard for those working on the rooftop.

The third alternative for installing roofing screws is the pneumatic screw gun, which is powered by an air compressor. The pneumatic patio roofing screw gun is attached to its air compressor by a long air hose, which like the extension cord on an electrical screw gun can be a real encumbrance when it is dragged around on the roof.The news come from http://www.bossgoo.com/
