Maintaining Your Green Roof
An increasingly popular installation for home and commercial property owners across the UK, green roofs are well-known for their positive environmental impact, helping to reduce energy costs and improve durability and performance in the process.
Relatively low-maintenance, green roofs won’t require extensive amounts of time and money spent on upkeep, but there are a few key maintenance duties one must be aware of when installing a green roof. In this helpful guide, we provide you with essential green roof maintenance tips, offering insight into their benefits in the long term.
You should try to inspect your green roof at least twice annually, keeping a close eye out for any weeds that have appeared, or seeds that may have been carried by the wind, before removing any unwanted vegetation by hand. Ideally, you should inspect your green roof during spring, and then again during the autumn, as this will present the best period for vegetation removal in preparation for summer and winter. Check your drainage systems and remove any leaves or blockages that may have built-up inside your gutters or drainpipes.
As an extension of the above rule, you should aim to fertilise your green roof at the start of spring and then again in autumn, (April and September are ideal), as this is the best time to fertilise your roofing successfully. Fertilisation is vital in providing the necessary nutrients to your green roof in order to encourage healthy growth and strong planting, preparing them for extreme weather conditions and flowering during the summer.
A properly installed and effective green roof system will generally require little to no additional water. Although extremely dry conditions are a caveat to this, for the most part, green roofs won’t need an additional water source. Depending on the climate zone of your green roof, it’s therefore highly recommended that you apply an irrigation system to your roofing. Irrigation systems are typically either visible sprinkler systems that imitates rainfall, or drip pipe systems that provide water directly to the soil and plant roots.
A key maintenance tip, removing any planting or vegetation that has encroached into drainage outlets, walkways and barriers should be removed. Removed vegetation can later be used to repair any bare patches that have potentially occurred. Equally, green roofs may sometimes produce moss and weeds, which can have a damaging impact on both the aesthetics of your roofing and the structural integrity.
