A green roof is much better for the environment when compared to traditional roofing materials, such as asphalt shingles or metal roofing. If you are interested in this type of roof you may be having a hard time deciding if you would like this. Below are some tips and information that you should find helpful, so you can start getting a new roof for your home.
Weight Loading Capacity
A green roof will add weight to your home and will be much heavier than any other kind of roof. Because of this, you need to hire a builder to ensure your home can handle the weight loading capacity of the roof you are installing. You will need to first determine the depth and size of the garden that you plan to put on the roof. Also, the roof will be heavier each time it rains or whenever you water it, as wet soil is heavier than dry soil.
Structure and Location
Your roof must be flat or have a very little slope to install a green roof. If the roof is not, the soil will simply fall off the roof onto the ground. Along with a flat roof, your home must be in the sun, as the roof will not grow well if there is a lot of shade on your home.
Go outside and look at trees close to your home to see how much shade they put on your roof. You can go out in the morning and write down how much of the roof is covered by the sun, then go outside in the middle of the day, then at the end of the day; this will show you how many hours of sunlight your roof gets.
Protection from Roots and Water
Over time, the roots of the plants will damage the roof if the green roof is not built properly. To prevent this from happening, a waterproofing membrane should be installed on the roof first. If the waterproofing membrane that is installed is not resistant to plant roots, however, you will have to also install a root barrier over the waterproofing membrane. The roof edges, joints, and roof perimeters must also be protected against roots.
Before you hire a roofing contractor, make sure they have installed a green roof before. This is important as if the roof is not installed properly it will damage your home.
