More: The cost of a new asphalt roof has risen by more than $6 million since 2007, according to new research.
The cost of the new roof, installed in the U.S. in 2008, has increased by an average of $4,000 per home since then, according the Urban Land Institute, a research organization.
The cost rose by nearly $6,000 for homes in the metro area of Washington, D.C., the researchers found.
The research was based on the cost of building a new roof per square foot, a key measure for determining the true cost of an asphalt roof.
It also includes the costs of installing and maintaining the roof and the cost to repair or replace the roof if it breaks down, said Urban Land Vice President Mark Zucarelli.
The study found that while the price of a roof is rising, it has decreased over time.
The researchers calculated the cost per square-foot of asphalt over the course of the 20 years of data available.
For example, in 2006, the price was $6.10 per square meter.
But in 2016, the cost was $4.70 per square inch, Zucatlli said.
The increase in the price is due to the cost that consumers are paying for the asphalt.
That’s a big part of why we’re seeing this increase in costs over time, said Zucielli, who was not involved in the research.
The asphalt costs are rising faster than other types of construction, like asphalt roads.
The price per square yard of asphalt in the District is $2.75 per square mile.
But that’s not a very high price for a new road, said Daniel Bader, a spokesman for the city of Arlington, which is located about 45 miles south of the District.
The Arlington, Virginia, city is replacing two asphalt roads with new roads with a cost of $2 per square acre.
And it’s replacing an existing road with a new one that costs $1.85 per square pound, according Bader.
In addition, Arlington has spent more than two years constructing new asphalt roads, and the city is spending more than 20 percent of its annual operating budget on road maintenance, Bader said.
Bader said that Arlington is trying to find ways to keep its asphalt cost in line with other parts of the country where asphalt costs more.
The city is also developing a plan to replace aging roads, he said.
The costs of building and maintaining asphalt roads have been rising for decades.
In 2010, the Urban Forum said the cost had increased by more then $2,500 per square ft.
