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.

Sounds to me like you might need an architect. DIY design sounds like a bad idea in this case. If I was an owner I would want a pro involved.

Tsilanko, I would always recommend professional installation where needed. But what I am doing here is suggesting that WHEN you are planning to build or renovate, to consider how your plans will affect you in 20 or 30 years time. Split levels are very hep when you are young. A kitchen 3 steps down at 30 is rarely a problem, but might be a hazard at 60, or, as Marjie1059 suggested, if you break a leg. ... All my parents' homes were terrible for old people. They were forced to move to a bungalow in extreme old sge because the location and design of their home was more suitable for an active young couple with a large family than for an elderly couple with stroke disabilities. I would not want to move again, so my present home has features built in that make ageing in place simpler. Mostly small changes, like grab rails, and lever handles on doors and faucets. A major disability suddenly suffered requires major changes if permanent. I did look at this because it came up in the discussion, but if you look at the heading, Planning for Disability, it means just that. Plan ahead so you don't have to make expensive changes later on. But thank you for your advice, yes, major changes are not in the DIY domain.

There are many roof systems out there, you have to see what is the industry standard for roof construction in India. You can take a look at this Website to get an idea what roof construction practices they use/d for that region. This is one of more up-to-date concrete roof structure.
