Flat roofs on older Boston buildings take a beating. Freeze-thaw cycles, pooling water, and aging membranes all add up fast - and when rooftop HVAC equipment is in the mix, the stakes get even higher. A failing roof doesn't just mean leaks. It means damaged equipment, disrupted tenants, and repair bills that spiral quickly.
Here's what we were working with on this Boston property - a full commercial roof replacement using a 060 TPO membrane. TPO is one of the most reliable choices for flat commercial roofs, and the 060 thickness is the right call when you need real durability. It handles UV exposure, foot traffic, and New England weather without breaking down the way thinner membranes do over time.
One of the bigger considerations on a job like this is working around rooftop equipment. This building has multiple HVAC units sitting up top, and every penetration, curb, and edge detail has to be done right. Sloppy flashing around equipment is one of the most common sources of commercial roof leaks - so we take our time on those details. A clean, tight membrane installation protects the building envelope and keeps that equipment running the way it's supposed to.
What we ended up with is a smooth, fully adhered TPO surface that gives this building a solid foundation going forward. Commercial roofing in a dense urban environment like Boston has its own challenges - tight access, neighboring buildings, fire escapes to work around - but the end result speaks for itself. This roof is built to last.
Whether your building needs a full replacement or you just want a professional commercial roof inspection to know where you stand, the right time to get ahead of it is before a problem shows up inside. Proactive roof maintenance is always cheaper than emergency repairs - and on a commercial property, the costs of waiting add up fast.
