Should I Get a Flat Green Roof?

There is a lot of conjecture in the eco-development industry as to whether or not a green roof can serve enough "eco-purpose" to be sufficiently worthwhile. This said, there is still much to be said for a green roof and the positive impact it could make to your home.

For one thing, their absorption qualities are multifaceted: absorbing radiation from the sun, CO2 from the atmosphere and a great deal of the water that falls on them (up to seventy percent, in fact). Not only this, but their insulation properties are also well defined: keeping buildings both cooler in the summer and warmer in the winter.

On top of this, they help replace the ecology originally removed at ground-level to allow the building's construction. Whenever you have flat roofing, you will need to have flat roof house insurance.

Aesthetically Appeasing

On top of all that, green roofs can also look very attractive and add some extra appeal to your home. There are three basic types of green roofing which you might consider for your home.

The first type of green roof is an extensive system. Extensive green roofs are fairly shallow, usually between 50 and 150 mm of substrate layer, planted with low-growing and stress tolerant vegetation. They require minimal maintenance (being mainly hardy grasses, mosses and sedum) and do not put much weight on the building.

Their insulation properties are less extensive than other green roof types, so conventional roof insulation will also be required. When you have an extensive green roof, you will need to have suitable flat roof insurance.

Intensive Green Roofing

The second type of green flat roofing is intensive green roofing. Intensive green roofs incorporate a thick layer of soil in excess of 200 mm. In this soil you can grow a number of plants; from grasses and herbs, to flowers and shrubs. In some cases you are even able to grow small trees.

These types of roof require access for maintenance, so need to be sturdily constructed with ample support, and can often double as recreational spaces. They provide a habitat for wildlife, offer great insulation and water absorption properties, but require a great deal of care and maintenance (like a comparably sized ground-level garden). If you have an intensive green flat roof, you will also need flat roof building insurance.

Semi-extensive System

The third type of green flat roof is a semi-extensive system. Semi-extensive systems fall somewhere between the other two types, usually requiring less maintenance than intensive types and constructed using the same techniques as extensive systems. They usually allow for a greater diversity of plant-life than an extensive roof, but have a slightly greater depth of substrate.

Having a flat roof can make it hard to find flat roof insurance, no matter what type of flat roof you might have.
