The tenant association president at Ingersoll Houses says it was nine years ago when roofs were replaced.

He showed us their current state and already the roof is bubbling.

"We have a lot of standing water here,” said Darold Burgess. “Again, these are some of the problems that the water leaks down into the apartments below."

There are pools of standing water. One top floor tenant says it’s leading to protruding paint and leaks in apartments.

“So what happens when it rains?” NY1 asked the tenant.

"The water enters the apartments. The water enters through the apartments through the ceilings," she said.

These bad roofs lead to leaks, which leads to mold. This is a fact City Comptroller Scott Stringer made clear just down the block on Friday.

"We can easily conclude this was gross mismanagement," Stringer said after releasing a blistering new audit of the agency.

His team inspected 35 roofs across NYCHA developments and found 88 percent of them had some sort of deficiencies.

NYCHA failed to do proper inspections and maintenance. And what's worse is these roofs were relatively new and under warranty.

The comptroller found NYCHA barely used the warranties to make fixes, essentially wasting more than $24 million of taxpayer money.

“In some cases, the report found, the building superintendent were not even aware of the warranty coverage,” Stringer’s report reads.

"And i respectfully say to the mayor, enough already. You have got to fix this. This is a management issue," Stringer said on Friday.

In response, NYCHA recognized it had a problem and claimed it was already working on it.

In a statement, a spokesman said, "The Comptroller's audit and recommendations are consistent with what the Authority has been aware of and addressing through new systems we are already implementing."

Tell that to NYCHA tenants.

"They put a band aid on the problem. They don't fix it entirely," said Burgess.

As water continues to pool on rooftops across the city, just last summer the de Blasio Administration announced it would be replacing dozens of roofs across the New York City housing authority. But clearly they have many more to go.
