A ladder is considered a simple machine called an inclined plane because it allows for easier vertical movement by spreading the force needed over a longer distance. A roof is not typically classified as a simple machine as it does not have mechanical moving parts to transfer or reduce force.
A roof is not a simple machine. It is a structure built to provide shelter and protection from the elements.
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.
The black-colored roof absorbs more sunlight and heat compared to the white shiny roof, which reflects more sunlight. This absorption of heat causes the black roof to become hotter than the white shiny roof.
Roof coatings can add life to a roof. Extra life may mean that you can wait years longer before replacing the roof and potentially prevent roofing material from winding up in the landfill. A coat of high quality EPDM Liquid Rubber can restore an existing roof to like-new condition. It may delay the need for roof replacement by adding up to 18 to 20 years of guaranteed life protection to your existing roof
Floating roof tanks are broadly divided into external floating roof tanks (usually called as floating roof tanks:FR Tanks) and internal floating roof types(IFR Tanks). IFR tanks are used for liquids with low flash-points(e.g. ATF, MS. gasolene, ethanol). These tanks are nothing but cone roof tanks with a floating roof inside which travels up and down along with the liquid level. This floating roof traps the vapor from low flash-point fuels. Floating roofs are supported with legs on which they rest. FR tanks do not have a fixed roof (it is open in the top) and has a floating roof only. Medium flash point liquids such as naphtha, kerosene, diesel, crude oil etc. are stored in these tanks. sealions

The preposition in the sentence is "against." The ladder was leaning against the roof.
