MULTI-UNIT FLAT ROOFING

Townhouse Roofing in St. Louis Park and Minneapolis

Most townhouse and apartment buildings in St. Louis Park and Minneapolis sit on low-slope or flat roof systems: TPO, EPDM, or PVC single-ply membranes, not residential shingles. The installation work, the drainage detailing, and the seam quality that determines a roof's lifespan are all commercial-grade skills. David Armenta built those skills over 10 years on commercial flat-roof crews before founding Altus.

Most residential roofers across the Twin Cities focus on asphalt shingle work. A flat-roof membrane system on a multi-unit building is a different trade, and it requires someone who has worked it. That background translates directly: the systems are the same, the manufacturer certification requirements are the same, and the standards for a properly installed drain or heat-welded seam are the same whether the building is a 200-unit apartment complex or a 12-unit townhouse association.

What Multi-Unit Roofing Requires

Replacing roofs across a townhouse association or apartment complex is not a single job. It is a sequence of jobs that have to be coordinated around occupied units, building management schedules, HOA board approval cycles, and sometimes insurance claim documentation.

Altus builds a per-building or per-phase written proposal before any work begins. The HOA board or property manager reviews pricing by building or by phase and approves each stage. David provides photo documentation at every milestone. On completion, a written summary goes to the board for records and capital planning.

TPO, EPDM, and PVC for Multi-Unit Buildings

St. Louis Park and Minneapolis townhouse and apartment stock typically uses one of three flat-roof membrane systems. David installs all three and is a Mule-Hide and GenFlex certified installer for each.

TPO is the most common choice for new installations: heat-welded seams, white reflective surface that lowers cooling cost, and a 20-to-30-year service life when installed correctly. EPDM rubber performs well in Minnesota's freeze-thaw cycle and stays flexible under heavy snow loads. PVC is the right choice when rooftop HVAC, grease venting, or chemical exposure is a factor.

After walking each building, David recommends the system that fits the drainage configuration, the existing substrate, and the budget.

Working on Occupied Buildings

Tenant disruption is the most common concern property managers raise when scheduling multi-unit roof replacement. Altus addresses it with a phased approach: work proceeds section by section, no tenant unit is inaccessible for more than a single workday, tenants are notified in writing before each phase begins, and the site is cleaned at the end of each day.

If a section develops an active leak before full replacement is scheduled, David addresses it the same week. The repair is documented and reported, and the notes are folded into the full replacement proposal so the scope stays accurate.

Documentation for HOA Boards and Property Managers

HOA boards need written records for capital planning, insurance filings, and reserve studies. Altus provides a photo-documented condition report before the proposal, a written scope with per-building pricing for board approval, progress photos at each phase, and a final written summary on completion.

Property managers overseeing multiple complexes can set up recurring annual inspection programs. Same inspector on every visit, consistent reporting format, written condition log for each building. Call (612) 749-6778 to discuss a recurring inspection schedule.
