There is very little a plumber could do to injuring himself or create a serious liability in terms of bodily injury to a homeowner or tenant (liability for property damage is a risk I'm often willing to take).As for electrical and HVAC, I nearly always want to have someone licensed and insured, as the liability is MUCH higher. 

I’d like to upgrade from asphalt shingles to a metal roofThanks!

At a little over 80K per unit this met all of my criteria for a good investment in this particular market.

Spend another $50 on a metal bracket.  

We are wanting to build a home with steel framing and metal exterior , similar to a commercial building but it will be our primary residence.  

We can’t use romex/ non metallic cable.

Metal roofing is then placed over the entire structure.

We used metal edging, "black star" gravel in the beds up front and seating area, planted sod (900SF by seating area), compacted pea-gravel on top of road base for the driveways, and did a planter at the corner of the property by the street.

Be careful with people who take them for free -- you're generally talking about scrap metal haulers and they might not be too careful about making a mess.
