Leo Pro Construction | Professional Roof Repair in New York, NY

Moisture control installation creates a critical barrier in your roof system. For chimney flashing leaks—a common issue here—we install specialized underlayments and sealants around the flashing to block water entry from wind-driven rain and ice dams. This proactive approach addresses the weak points before water can damage your roof deck, ceilings, and walls.

Often, a targeted waterproofing repair is sufficient. We assess the extent of the underlayment damage, which is frequently caused by trapped moisture or aging in our local climate. Our repair process involves carefully removing affected sections, installing new, high-grade underlayment, and integrating it with a waterproofing membrane to restore integrity without the need for a full roof replacement.

For NYC foundations, our waterproofing installation starts with excavating to expose the wall, repairing any cracks in the masonry, and applying a thick, brush-on membrane or dimpled drainage board. We then install a perimeter drainage system to channel groundwater away. This comprehensive process is crucial here to combat soil saturation and hydrostatic pressure, preventing basement leaks and structural moisture issues.
