Just like when you’re shingling a roof, you can install felt underlayment under a metal roof, but a synthetic underlayment like adhered ice and water shield is the best option. These use adhesives rather than mechanical fasteners, so you have fewer penetrations going through your roof deck and a lower risk of leaks. Ice and water shield is also easier to install because you don’t need additional tools or fasteners to attach it to the roof deck.

Mansard roofs are still popular in Paris, where they originated, and throughout France. In the United States, you can find mansard roofs on some older buildings in Manhattan.

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.

When choosing a roofer to install a green roof, look for someone with experience who specializes in green roofs.
