If your roof has isolated damage, a repair may be enough to restore performance. If you are dealing with recurring leaks, widespread membrane damage, aging materials, saturated insulation, poor drainage, or repeated storm-related issues, replacement may be the smarter long-term investment. Our team helps you compare both options clearly so you can make the right decision for your property.

The right commercial roof depends on your building’s size, slope, drainage, existing materials, budget, and long-term goals. At CML Roofing & General Contracting, we inspect the full roofing system and help you understand your options, whether your property needs flat roof repair, metal roofing, single-ply membrane roofing, built-up roofing, roof coatings, or a full replacement.

Commercial roofs in Maine and New Hampshire deal with heavy snow, ice buildup, coastal moisture, wind-driven rain, freeze-thaw cycles, and seasonal temperature swings. Over time, these conditions can contribute to leaks, open seams, ponding water, flashing failure, roof edge damage, punctures, and moisture getting into insulation or decking.

This is especially important for flat and low-slope roofs, where drains, seams, penetrations, rooftop units, and ponding water can all affect performance.
