Metal roofing, says this advocate, has major "eco advantages" over other types of roofing.

Unmatched in longevity, durability, and cost-effectiveness, metal roofing is also gaining popularity for its myriad eco-friendly benefits as well. Below, we’ve listed the four biggest advantages to installing a metal roof, and why this is one upgrade you seriously need to consider during your next home renovation.

Deck: The substrate over which roofing is applied—usually plywood, wood boards or planks.

Drip Edge: An installed lip that keeps shingles up off the deck at edges and extends shingles out over eaves and gutters to prevent water from wicking up and under the shingles.

Exposure: The area on any roofing material that is left exposed to the elements.

Flashing: Materials used to waterproof a roof around any projections.

Granules: Crushed rock that is coated with a ceramic coating and fired, used as top surface on shingles.

Ice Dam: Formed when snow melts on a roof and re-freezes at the eave areas. Ice dams force water to “back up” under shingles and cause leakage.

Laminated Shingles: Asphalt-based shingles made from two separate pieces that are laminated together. Also called dimensional shingles or architectural shingles.

Soffit Ventilation: Intake ventilation installed under
the eaves or at the roof edge.

Steep-Slope Roofing: Refers to slopes steeper than a 4” rise for every 12” of length (expressed as 4:12).

Tear-Off: Removal of existing roofing materials down to the roof deck.

Valleys: Areas where two adjoining sloped roof planes intersect on a roof, creating a “V”-shaped depression.
