911 Alexander Construction | General Contractors & Roofing in Hauppauge, NY 11788

Living on Long Island, we understand how common and urgent storm damage can be. Our process starts with a thorough, local inspection to assess not just the shingles, but the underlying roof deck for rot or structural weakness—a critical step often missed. As a licensed roofing contractor, we handle the full repair, from emergency tarping to complete replacement, ensuring it meets local building codes. We're also licensed in water damage remediation, so we can address any related interior issues to prevent mold, providing a comprehensive solution for Hauppauge homeowners.
