Who we are

MRS is an Auckland membrane roofing contractor, run by Mussi Jorge Rosa. With 11+ 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.

Process

How we work.

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.

Where we work

Headquartered in Auckland, working across Aotearoa.

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.
