The Right Call, At The Right Time
Replace with a crew that knows Boston weather.
Our crews are local - they know what New England weather does to a flat roof, from freeze-thaw cycles to nor'easters and summer heat. We replace yours with a system built for Boston's climate - to last decades on a single investment.
Anatomy of the system
Engineered, not pulled off a shelf
Every scope starts with a roofing system design built around your building - deck type, slope, drainage, insulation value, and wind uplift.

Crown replaces and installs roofs across Greater Boston's commercial, institutional, and multi-unit building stock - the property types that keep a neighborhood standing and dry.

Most flat commercial roofs are replaced in a few days to a couple of weeks, depending on square footage, deck condition, and weather. We give you a firm schedule up front and stage the work to keep your building operating throughout.
Yes. The vast majority of our commercial replacements happen while tenants and operations continue as normal. We coordinate access, noise, and any sensitive areas in advance so disruption stays minimal.
It depends on your roof's slope, rooftop traffic, exposure, and budget. We'll inspect first and recommend the system - TPO, EPDM, PVC, or modified bitumen - that delivers the best lifecycle value for your specific building, not a one-size-fits-all answer.
It depends on the roof's size, the system specified, and the condition of what is under the old membrane. We inspect first, then give you a fixed, transparent quote - free and with no obligation.
We register your manufacturer warranty and add it to a Crown Care maintenance plan so scheduled inspections keep the warranty valid and the roof performing for its full service life.
