Cost Savings of Green Roofs

I recently subscribed to Dave Hilary's course of Green Roof Lessons via his website www.greenroofplan.com and I have to say, I like the way he breaks down the benefits of green roofing into simple, easily understood, bite-sized pieces.Here's an extract from "Lesson 2, Extensive Green Roofs are an Easy Call"The cost-benefit analysis is likely to be your driving factorbehind choosing an extensive green roof. The factors to look forinclude:Rooftop replacementRooftops have to be replaced frequently due to the impact ofsunlight, especially ultraviolet (UV) rays. That's right, the samewavelengths of light energy from the sun that cause skin canceralso cause your rooftop's underlying material to break down.Heating costsA green roof is likely to cut your heating costs by helping toretain natural heat, plus the heat that you pay big bucks to bringinto your home. The green roof is like a hat on a bald head - itretains warmth, cutting your costs.Cooling costsWith a green roof, your house never heats up so much when the sunbeats down on it. This reduces not only the cost of running yourair conditioner, it reduces roof replacement costs by lowering peakhigh temperatures.An extensive green roof keeps you off the peaks, and therefore islikely to save you money. It also features lower costs forstructural strengthening, setup, and maintenance. You can always domore later if you decide to do so, but an extensive green roof is aworthy starting point - and perhaps ending point - on youradventure.All of these points and more are covered in Dave's e-book which is downloadable from his web site and they're also incorporated into Enviromat's Green Roof Information Days.The next Green Roof Information Days are on 23rd November 2010 at The Berkshire College of Agriculture and again on 1st December 2010 in Hockwold, Norfolk. There's no charge for either of these events, but places are limited so if you fancy coming along, please let me know so that I can reserve a place for you.

I would love to hear if anyone has had an experience of paving being pushed up because of the hot and dry weather this summer. We have had a number of patios where this has become a problem (a couple we laid ourselves and quite a few more where…
