MRS is an Auckland membrane roofing contractor, run by Mussi Jorge Rosa. With 12+ years on roofs across New Zealand and a Licensed Building Practitioner ticket in Roofing, Mussi handles every job personally — quote to flood-test. Most of our work is commercial and multi-residential; we also do high-quality residential flat roofs where the architecture calls for it.
At Membrane Roofing Systems, our mission is to protect homes, businesses, and major projects across New Zealand with reliable, durable, and high-quality waterproofing solutions.
With 12+ years of experience, we bring precision, transparency, and commitment to every project — from minor repairs to complete membrane roofing installations. We use trusted materials and follow New Zealand building standards to deliver results designed to withstand the country's demanding weather conditions.
We don't just install roofing systems — we build long-lasting protection and trust.
Owner-operated by Mussi Jorge Rosa. The full crew that delivers every membrane install, repair, and flood-test.
Every job starts with a site visit. We assess the substrate, talk through the options, and issue a written quote within five working days. On-site, we follow the manufacturer's spec, log progress, and flood-test before handover. You receive a Producer Statement, the manufacturer's warranty, and our 5-year workmanship warranty in writing.
MRS is based in Auckland and takes commercial and multi‑residential work across the country — from inner-city Auckland reroofs to projects in Dunedin and Otago.
Email or call. We'll book a site visit and come back to you with a written quote within five working days.
