on a building, it apparently tells firement the building has a (R)egular roof as opposed to a truss roof. Truss roofs tend to colapse in fires, so firemen do not get on top of it.
Well the UPC (uniform plumbing code) has the information but your drain line going outside the building and your vent line going outside the roof has to meet the same square inches. So if you have a main dran line that is 4" running outside the building then your must have enough square inches of pipe going threw the roof in example ( you would need four 2" vent pipes to equal one 4" pipe). Trailer homes don't follow the code and they go by the AWC (almost works code)
The area of a roof can be determined from the area covered by the building to the outside of the walls and taking in to account the pitch of the roof by adding on a percentage depending on the pitch. A method is shown at the web link below along with a table of the percentages to be allowed.

At least 24 feet high, based on 8-foot ceilings. If the 3rd floor is built into the roof, the building will be shorter than if there is a separate attic under an angled roof.
Hot air rises, so to keep the heat in the building, you need to insulate the inside of the roof.
The best roof insulation material for maximizing energy efficiency in a residential building is typically spray foam insulation. It provides a high level of insulation and helps to seal any gaps or cracks, reducing energy loss and improving overall efficiency.
Ornl.com has said that blanket roof insulation is the best type of roof insulation. They are very helpful and good for insulating your roof. Ornl.com is good for roof insulation.
The best materials for roof insulation to ensure energy efficiency and temperature regulation in a building are typically foam board insulation, spray foam insulation, and mineral wool insulation. These materials provide high levels of thermal resistance, helping to keep the building cool in the summer and warm in the winter, thus reducing energy consumption and costs.
Installing insulation under the roof of a building helps to regulate temperature, reduce energy costs, and improve overall comfort by keeping the interior cooler in the summer and warmer in the winter. It also helps to prevent moisture buildup and protect the roof structure from damage.
A warm roof has insulation above the roof deck, keeping the structure warm, while a cold roof has insulation below the roof deck, allowing the roof to stay cold. The choice between a warm roof and a cold roof depends on factors like climate, building design, and budget. In general, a warm roof is more suitable for buildings in colder climates to prevent heat loss, while a cold roof may be more appropriate for buildings in warmer climates to prevent condensation issues. Consulting with a roofing professional can help determine the best option for your specific building.
The best methods for installing metal roof insulation to ensure energy efficiency and temperature regulation in a building include using high-quality insulation materials, properly sealing gaps and joints, and ensuring proper ventilation to prevent moisture buildup. Additionally, installing a radiant barrier under the metal roof can help reflect heat away from the building, further improving energy efficiency.
The best materials for installing roof deck insulation to improve energy efficiency and temperature regulation in a building are rigid foam boards, spray foam insulation, and mineral wool. The methods include ensuring proper installation to minimize gaps and air leaks, using reflective barriers to reduce heat transfer, and considering the climate and building design for optimal insulation performance.

Spray roof insulation can be very effective in reducing energy costs and improving a building's efficiency. It helps to seal gaps and prevent heat loss, leading to lower heating and cooling expenses. Additionally, it can improve overall comfort by maintaining a consistent temperature inside the building.
Yes, loft insulation is a good insulator because it helps to reduce heat loss through the roof of a building. It can help to improve energy efficiency and reduce heating costs by trapping heat inside the building.
