Lisle's Trusted Flat Roof Installation & Repair Experts

Lisle properties often combine office use with mechanical-heavy rooftops. Set raised curbs, flash to the correct height, and keep crickets behind units. Confirm that overflow routes exist so blocked drains do not force water under flashings.

TPO supports energy goals with reflective surfaces. EPDM tolerates structural movement. Modified bitumen is dependable at detail-heavy edges. Protect service routes with pads and document work with photos.
