About MJB Roofing & Siding

Our Story

MJB Roofing & Siding is a locally owned and operated business based out of Manorville, New York. Founded on the principles of outstanding communication, premium local craftsmanship, and reliable customer care, we have grown into one of Long Island's most trusted exterior contractors by treating every property as if it were our own.

Unlike large, detached regional operations, Mike and the MJB crew bring deeply localized knowledge to every single job site across Nassau and Suffolk Counties. We understand the specific demands that Long Island weather puts on a home—from coastal storm winds and heavy winter snow to high humidity. We know how active leaks can rapidly threaten a building's structure, and we specialize in technical details like converting high-maintenance old wood shingles into long-lasting architectural asphalt shingles.

Our outstanding local reputation is built on accountability. We stand out by offering rapid project turnaround times and an unyielding 100% Clean Yard Guarantee—ensuring your landscaping is left entirely immaculate and free of debris. When you work with MJB, you get transparent, honest roofing advice without any cutting corners or high-pressure upselling.
