Family-Owned
& Operated Since Day One
JAGG isn't a franchise, a corporate outfit, or a call center that dispatches subcontractors. We are a Long Island family business — and we have been from day one. That means every decision we make reflects our name, our community, and our reputation.
Over 50 years ago, we started with a single commitment: do the job right, treat people honestly, and stand behind your work. That hasn't changed. Every project we take on is handled with the same care we'd give our own home.
- Locally owned and operated — we live and work on Long Island
- Over 50 years serving the same communities
- Not a franchise — every job is our personal responsibility
- Our name is on every truck, every shingle, every job
- Committed to Long Island homeowners — not shareholders
Industry-Leading
Warranty Coverage
Every JAGG project comes with both a manufacturer's warranty on materials and a workmanship warranty on our installation. You get complete written documentation before we leave the job.
As an Owens Corning Preferred Contractor, we offer access to extended manufacturer warranties — up to a lifetime on qualifying roofing systems. These cover defects in the materials themselves and are among the strongest in the industry.
Our workmanship warranty covers the quality of our installation — not just the materials. If something goes wrong because of how the job was done, we come back and make it right. Period. No runaround, no fine print.
Owens Corning warranties on qualifying systems are fully transferable to new homeowners if you sell your home. That makes a JAGG roof a selling point — not just a cost. Coverage that adds real value to your property.
* Specific warranty terms vary by product, system, and scope of work. All warranty documentation is provided in writing before the project begins. Contact us for details on the specific warranty coverage applicable to your project.
