Roofs are critical structures that cover and protect a house. There are several different materials that roofs have been made out of over the years including wood, asphalt, metal, and tile. Each roofing material has different advantages and disadvantages, and some are better than others for the environment.
Metal roofing has many environmental advantages. First of all, it is a
recyclable material; it won't sit for centuries in a landfill never degrading.
It is also environmentally friendly because it reduces waste. Many times, metal
roofs can be installed on top of an existing roof. This erases the hassle of
tearing off the new roof and spares the environment the waste.
Metal roofs are naturally safer for the environment when it rains. Some roofs
have chemicals and contaminants that will run off the roof and pollute the
ground when it rains. Metal is free of chemicals and the rain that slides off the
roof is cleaner as a result.
Metal roofs are good insulators when installed properly. This insulation can
help keep the house warmer in the winter and cooler in the summer, reducing
energy costs. The less energy used heating and cooling, the better for the
Certain types of foam roofing can also have environmental benefits. Newer foams
are made without chemicals that could be harmful to the ozone layer.
Foam roofing causes much less waste when compared to asphalt roofing. This type
of roofing also lasts a long time and doesn't have the dangerous asphalt
chemicals or odors.
Wood roofing has obvious environmental benefits because it is truly a renewable
roofing choice. The wood used is natural and won't harm the environment. The
processes of manufacturing the wood roofs use much less energy than other
manufacturing processes and as a result produce much lower amounts of
Wood roofing is also very good at insulating a house and keeping the environmental
cost of heating and cooling down.
When searching for a roofing choice that has environmental benefits, metal,
foam, and wood roofing all have their own advantages, but metal is perhaps the
