Top-Line Roofing & Sheet Metal Inc. specializes in all types of roofing installation, including complex commercial roofing projects. We understand the diversity of the commercial roof systems, and we are certified by the leading manufacturers of commercial roofing material to install their products.

We realize your business needs to keep operating during the roofing process. We minimize our obstruction to parking facilities and entry ways to keep your operations flowing smoothly.

Commercial flat roofs pose some of the greatest challenges for a roofing company. Large flat expanses, heating, air conditioning machinery, air vents and piping, all create obstacles to making a roof watertight and long lasting. We have the experience and craftsmanship of product installation to meet and exceed requirements for commercial roofing of all types.

Commercial Flat Roofs

Commercial flat roofs present many obstacles you will not find on a pitched roof. Building ventilation system, large AC units, etc, along with numerous vent piping and other protrusions. Not only are these obstacles, they can also be, depending on the roofing material used, a source of continued maintenance expense.
