7 Reasons You Should Invest in a Green Roof

The initial cost of a green roof might be more expensive than a conventional roof system, but it’s sure to have a stronger long-term effect. Here are seven reasons a green roofing project might make sense for you:

Less Stormwater Runoff

Green-built roofing systems are equipped with water buffers, which are high-tech water absorption devices. Not only do they absorb rainwater, but they filter and direct it into a drainage system. This helps delay the discharge of rainwater into sewers. From there, any leftover rainwater is purified, which benefits the health of any plants growing on the surface level as the filtered water supply evaporates through the vegetation. This stabilizes the water at the ground level, reduces pressure on the sewage system, and prevents major flood risks.   

Lower Utility Costs

Climate control makes up a major portion of energy bills, and green roofs help keep those expenses at a minimum. The plants found growing on the surface of a green roof system operate as an insulator. This is essentially a heat-filtering system in which the vegetation directly absorbs the climate. The plants only let in an appropriate air temperature, which helps keep the building comfortable. 

Better Air Quality

Rooftop plants trap debris, dust, and other particles that build up in chimneys and vehicle exhaust systems. This helps purify the air as it converts any carbon dioxide matter into oxygen. The vegetation helps reduce electromagnetic radiation as well.

Reduces Ambient Heat 

Green roofs can help enhance the performance of a central air conditioning system. Plants absorb all external sunlight, which helps minimize the risk of the building overheating. Fifty-percent of what is absorbed is used to enhance a plant’s growth, while the remaining 30% is retained in the HVAC system. 

Delivers More Fire Resistance 

When you hear the term “green roof,” chances are you don’t think of a fire-proof material. But this might be one of the safest roofing options to consider. Each plant naturally contains a lot of moisture, making the vegetation layer the perfect fire-resistant surface for any home or office building. 

Less Maintenance and More Cost Savings

A green roof costs a lot upfront, but you won’t have to keep pouring cash into maintenance. The installation is quick and easy and any recurring maintenance is minimal. And if you really want to get the most out of your investment, you should invest in a vegetation blanket to help distribute an adequate amount of sunlight and water. This mat practically maintains itself, helping you save more time and money. It retains rainwater for extended periods of time so there’s no need to schedule heavy maintenance. 

Longer Lifespan of the Roof

Green roofs are built to last 30 to 50 years. This is much longer than a traditional roofing system, as they are projected to survive 15-25 years, but that’s only with the proper maintenance. Since green roofs require very little upkeep compared to any conventional metal roofing structure, you won’t have to spend much money on repairs and other labor services.
