Common questions

Is $25,000 a lot for a new roof?
For a new roof in the District of Columbia, a $25,000 cost can be within the expected range, depending on factors such as the home's square footage, the quality and type of roofing materials selected, and the complexity of the roof structure. Larger homes or premium materials will naturally increase the overall investment. Detailed, itemized quotes are recommended.
How much does it cost to put a shingle roof on a 2000 sq ft house?
The cost to install a shingle roof on a 2000 sq ft house in the District of Columbia will vary based on the specific shingle product chosen, from standard asphalt to higher-end architectural shingles.

What is a fair price for a roof repair?
A fair price for a roof repair in the District of Columbia is determined by the extent of the damage and the labor involved in the repair.
