Devastated friends of the roof-jumping teen who plunged to his death from a Brooklyn building wept on the street Saturday, just blocks from where he died.

More than a dozen teens created a sidewalk memorial to Rame Pierre-Louis near his Bushwick home, with white balloons, pictures, and sidewalk chalk messages of “RIP Rame.”

“He was a good person. He always got along with everybody,” said Isaiah Almodovar, 13. “I didn’t believe this at first. To be such a young age, it’s hard to believe.”

Leo Cordero, also 15, said Rame “was cool, he was chill, he was nice. He was a good kid.”

Rame was hanging out on a roof of a Grove Street building with a 15-year-old pal Friday evening when the teens, who were allegedly trespassing, tried to run when someone yelled out that cops were coming, a source said.

They tried to jump from one roof to another, but fell four stories into a rear alley.

Rame suffered severe head trauma and was pronounced dead at Kings County Hospital. His friend suffered a broken pelvis, but is expected to survive.

A half-uncle said Rame’s father, Ray, is “going crazy” after his son’s death.

“He don’t want to live no more,” said the man, who said his name was also Ray. “Rame was a good kid from a loving home. For him to end like this is devastating to his whole family. It’s unbelievable.”

The uncle acknowledged that kids hung out on the roof, even if they didn’t live at the Grove Street building where Rame fell.

“They even have a lounge chair up there … it should have never been,” he said.

Teacher Jennifer Ramos comforted Rame’s friends, who all attend IS 347 on Starr Street.

“He was a good kid, really engaged. He liked to goof around a lot. He liked to sing, make silly faces, dance. He always walked down the hall with music on. He tried to make the best of life. It didn’t matter that something was tough, he always tries to make the best of any situation,” the teacher recalled.

The eighth-grader, who loved basketball and handball, was on the school’s dance team, she added.

“This is so unbelievable. It just can’t make sense. His mom is devastated. She just can’t believe it herself. It’s hard to cope. She just can’t believe he’s gone,” she added.
