If the mold is showing on the underside of the overhang of your roof, it is likely that the heat escaping from your house is melting it. You may need a deeper overhang. Your roofing material may also be failing at that point, causing a leak. Contact a licenced contractor or roofer for further information.
If by "inside the roof" you mean the underside of the plywood up in the attic or crawlspace, the issue of melting ice is still true and water is leaking into the home. Water is coming in and freezing causing the appearance of frost. The black is mold and will eventually destroy more than just your roof. Your family's health can be directly affected by the presence of mold in your home. Get a licensed contractor or certified roofer to inspect. Proper insulation and ventilation will keep your roof functioning for years. A few hundred dollars now in repairs will save thousands later if you have to replace the entire roof! If it is in one area, there is an air leak causing warm moist air to escape from the living area. commonly found over bath vent fans and ceiling fixture boxes. seal air flow with spray foam, not just insulation. if over large area then you need more roof ventilation. my experience shows "code" ventilation isn't enough.
Snow acts as an insulator, trapping heat inside the house by preventing it from escaping through the roof. The snow on the roof forms a barrier that reduces heat loss, helping to keep the interior of the house warmer.
It is not normal for water to leak into the inside of your GMC Envoy XUV. The repeated replacements of the roof suggest that the issue has not been properly resolved. You may want to seek a second opinion from another mechanic or contact GMC directly for further assistance.
The minor salivary glands include the labial glands (inside the lips), buccal glands (inside the cheeks), palatal glands (in the roof of the mouth), glossopalatine glands (on the back of the roof of the mouth), and lingual glands (under the tongue).
White material reflects thermal radiation whereas black and other dark colors absorb more of it, so a dark color roof will get warmer and pass more heat into the house by convection and radiation. Me, if I lived in a cool climate, I would want a dark colored roof. If I lived in a warm climate I would want a light colored roof. I was a HVAC service tech for 38 years.
Sprinkling water on the roof after a hot sunny day can help cool down the surface temperature by evaporative cooling. The water absorbs heat from the roof and evaporates into the air, taking away some of the heat in the process. This can help regulate the temperature inside the building and reduce the overall energy usage for cooling.
Strearks on roof
no
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.
no. roof is the outside ceiling is the inside
The purpose of having roof vents are the following; preserving the life of the roof, reducing the moisture inside the roof, maintaining the right ventilation inside the roof to avoid molds and moisture and for aesthetic and style purposes as well.

Frost forms on car roofs first because they cool down faster due to the lack of insulation compared to the car's body. The roof is also exposed to the open sky, allowing it to radiate heat more efficiently and reaching the dew point sooner. As a result, frost forms on the roof before the car's sides.
Have you tried putting a roof on it? if the roof doent protect it than you can move it inside the garage or somthing.
Not enough ventilation. Moisture from inside the house is condensing on the underneath side of the roof.
Because white reflects heat whilst black absorbs it therefore a white roof will keep the house cooler as the suns rays will bounce back off of it whereas a black roof will absorb the suns rays.
