When it is time to use a power saw for any type of cutting operation, select the right saw for the job. There are many different types of power saws available.
When cutting a roof material or wall material, you will need portability and power so that the cuts can be made effectively. Gas-powered saws provide the best option for both power and portability. A battery-powered saw offers portability but not much power. The duration of cutting operation will only last as long as the battery.
