I don't think roofs need the shape, but it is the support that matters. The roof shape could be like this: ^ It resists snow buildup and wind.
For most people, the choice is primarily asthetic. The cross gabled roof is cheaper and easier to build, but it is not ideal for high wind situations. The cross hipped roof is more complex but will withstand stronger winds. However, it leaves less under roof space for potential storage and ease of maintenace.
The wind speed. The angle of attack of the kite to the wind. The weight of the kite.
Weight and area exposed to the wind are key factors in kite design. The greater the effective area facing the wind and the lighter the kite, the less wind you need to get the kite off the ground.
It is almost impossible to answer, depending on pitch, dormers, valleys. Get an estimate from homedepot, then you should be able to get a real good roofer that will do it for almost 1/2 the price they quoted you. I had a customer call them and was quoted 18,000.00 I did it for 10,000.00 with 30yr shingles wind rated, new felt,, ice/water barrier on all edges, top of the line ridge vent.
Typically used for overhead beams in residential home applications or can be laminated to create a larger dimensional beam for spanning overhead across larger distances when the architect calls for an "open" floor space. Applied with the rise of the beams (12" width) sitting vertically, evenly spaced across the ceiling and braced with cross bracing material and resting atop vertical walls. Creats structural rigidity and suppresses torsional force from both down force (the weight of the force from above i.e. a 2nd floor, roof and/or wind). Build a home with only walls and a roof and push down on it with any amount of force and you'll see, exhibited by the walls, a flex, a twist, then structural failure resulting in a collapse.

A normal roof can typically withstand wind speeds of about 90-100 miles per hour. However, the exact wind resistance of a roof depends on various factors such as the type of roofing material, roof pitch, and how well the roof is installed. It is important to ensure that your roof is properly constructed and maintained to withstand high wind speeds.
the rocks on the roof is use to add weigth on the roof specially when heavy wind is on your place
The Bernoulli principle states that as wind flows over a roof, the pressure is lower above the roof compared to below it. This pressure difference creates lift, which can exert an upward force on the roof. If the force of the wind exceeds the strength of the roof's structure, it can cause the roof to lift off the house.

Sand dunes are shaped by the wind in both deserts and beaches. The wind blows grains of sand, causing them to accumulate and form dunes that can vary in size and shape depending on the strength and direction of the wind.
Metal roofing is an excellent choice in wet areas. New metal options are rust-resistant and waterproof. The solid metal surface also resists algae growth. Hail might dent metal, but hail can damage almost any roof. Flat sheets of metal roofing also have more wind resistance than most shingle roofing. Hurricane-force winds can blow shingles off the roof.
