After spending several years abroad I can share my observations. Most homes with snow fall use spanish or a slight curve. This is in an area that has: high winds, 2-4 ft snow intermittent years, and rain every third day. For snow and ice, some (but not many) have custom log braces about 4 foot from the gutter line. To be honest, falling snow and ice is part of living in colder climates. I would ask this company to get you in touch with their clients who own "the system" they are advocating. This way, you'll know what to expect from the product. If the shields help melt snow and ice, perhaps this is a good thing. All I would add to that is your offload gutter system and spouts are placed properly to avoid splashing against the home. I'll post a link if I find one that shows you what I am talking about in Europe.

vedikaseth Bombay rains are harsh! The one thing you can do is use flexible covers that work similar to roller blinds, and are transparent which allows the light to enter. There are many companies that offer such a product. Just choose one where the installation is easy and taking down the sheets is not an issue once the rains are over. Do keep in mind however that the water will still enter the balcony, you will simply be reducing the force of rains, and will require a water outlet.

Hi Chandru, Namashkar, Why dont you go for green roof or say slab with undulations which way you can cut direct light and heat along with that which can also have ventilation . water can be used as an element may be in the form of water tank to cool the roof or say roof garden. Thanks and regards Riddhish

Please can someone tell me how to prevent rain water seeping in this kind of roofing. I can't use any kind of sheets as the temperature indoors increases.
