The best tool for cutting metal ducts depends on the duct's shape and thickness. For round ducts, a duct cutter provides accurate, clean cuts. Reciprocating saws equipped with metal-cutting blades are versatile and suitable for both round and rectangular ducts. They offer speed and precision, especially for thicker metal. 

Tin snips are handy for intricate cuts or smaller ducts. However, an angle grinder with a metal-cutting wheel is powerful and efficient for large or thick metal ducts. 

The average roof requires about 17 metal sheets, but that varies according to house size and roof style. Each roofing sheet takes about five minutes to measure and cut, though this depends on your level of experience. If your roof has a steep slope, gables, and skylights, for example, it may require extra sheets to account for waste. Roofs with a steep slope over 3:12 typically require more sheets because the pitch adds extra inches. How much exactly you will need depends on the height versus the width of the roof. If you are unsure of the calculations, check with a local roofing professional.

You should not do your own welding unless you have the proper training and experience. Most home electrical systems can only handle MIG welding, which creates weaker bonds than TIG welding and won’t work on certain metals or metal thicknesses. Both welding forms usually require the use of shielding gas, which can be dangerous to store at home. Additionally, welding machines create temperatures of over 3,000 degrees, and the sparks can blind you if you don’t have the proper equipment. As such, it’s usually better to hire a professional welder for your welding projects.

After finding a local pro, you can inquire about steel fabricators' costs by sending details related to the dimensions, angles, and intended use. Most fabricators will use drafting software to bring your project to life before you settle on a price.
