Elements that Keep Your Home Cool under a Metal Roof

Metal, regardless of alloy or mixture, is known for having the property to conduct or radiate heat fast. When used as a roofing material, it can radiate heat into the house, causing more energy consumption for air conditioning and ventilation units. Surprisingly, metal continues to become a roofing material of choice around the world despite this drawback.

People choose metal roofing for its light weight, durability, easy-install characteristic, and recyclability. It is hard to ignore these qualities, which are rare in other roofing materials, just because a metal roof radiates heat into the house quickly. Instead, innovations in roofing design are employed to counter heat absorption and radiation. There are several elements that keep your home cool despite having a metal roof.

Underlayment

Before metal sheeting is laid over the rafters, an underlayment is installed to provide a partition between the roof and the house. This layer serves as a protection against climatic elements, especially heat from the sun. Some of the most common commercially available underlayment materials are made from rubberized asphalt, organic fiberglass, and synthetic.

Mechanical Vent

In states with a humid subtropical or hot climate, especially during the summer, having a thick underlayment and a fully-functioning air conditioning unit may not be enough to counter heat moving into the house. A mechanical vent is required to blow away hot air forming within the deck and eventually seeping through the pores on the ceiling. This device improves the energy efficiency of homes by helping minimize constant use of the air conditioning system.

Ceiling

Aside from hiding wires and trusses and providing a surface for lighting fixtures, your home’s ceiling serves as a secondary underlayment. Roofers Maryland and other prominent states recommend decide on the thickness of the ceiling material to be installed based on the level of heat to be countered. The ceiling keeps the heat accumulating within the deck from directly seeping through the house. The wood trusses and decking also help the ceiling shield the house against heat.

Pitch

This is not a definite material but a design which contributes to the minimization of heat transfer into the house. With sufficient pitch, it will take longer time for heat to travel from the metal roof to the deck; before heat reaches your home interior, it already cooled down. A roofers Maryland has to offer recommends high pitches for roofing to increase heat resistance in homes.
