Common questions
What is the 25% rule for roofing?

What is the cheapest month for roofing?
In New York, you might find that the late fall or early spring months offer better pricing for roofing projects. Contractors often have more availability during these 'shoulder seasons' outside of the peak summer construction demand.
Which company is the best for roofing?
The 'best' roofing company in New York is often one with extensive experience in the local climate, a strong portfolio of completed projects, and excellent customer reviews. Look for licensed and insured professionals who understand the specific needs of NYC buildings.

A fair price for a new roof should reflect the quality of materials, the skill of the installation team, and the specific requirements of your property. Obtaining multiple detailed quotes from reputable roofing contractors is the best way to ensure you're getting good value.
Can waterproof sealant help my New York roof?
Yes, for specific issues like sealing small cracks, around vents, or minor seam separations, waterproof sealant can be an effective solution for New York roofs. It's a valuable tool for preventing immediate water intrusion and can extend the life of your current roof.
