Trenton, NJ Metal Slate Roof Installation
For this metal slate roof installation in Trenton, NJ, we replaced this home's existing 103-year-old slate roof. Aside from chips and cracked slate, the built-in gutters tend to overflow, so better water management was a must for this project. To keep that historic look, we stuck with metal slate. Aside from its gorgeous designs, metal roofs are also incredibly durable. They are tested to withstand hurricane-level winds and impacts from debris. Plus, metal roofs reflect heat back to the source, helping to keep heating and cooling costs down. With all of this in mind, this roof could easily last as long as the original.

Shingle and Flashing Installation in Princeton, NJ
This asphalt shingle roof replacement in Princeton, NJ featured Onyx Black Owens Corning Shingles. The old 20-year-old shingles had some pretty serious leaks, so we had to replace some of the rotted out wood while putting an extra focus on protection from future leaks. We used OC Synthetic Deck Defence and OC Weatherlock Prograde as the underlayments and ice and water leak barriers. Owens Corning shingles bring cost-effectiveness to a durable, longlasting roof. These shingles can resist strong winds, maintain their color, and keep up their excellent performance for decades. Plus with the black look and the contrasting copper flashing on the chimney, the new look of this home is gorgeous, modern, and unique.

Installing Marvin Infinity Fiberglass Casement and Picture ensembles and Half Moon Windows with White Interior and Exteriors and no Grilles in Pennington, NJ

For this window replacement in Pennington, NJ, we replaced the home's original single-pane wood windows. Replacing original wood windows is always bittersweet, but the windows' performance has significantly declined and needed to be replaced. We installed three sets of fiberglass casements along with pictures and a half moon windows. The new fiberglass frame naturally resists expanding, contraction, warping, and cracking, unlike wood. So these windows will see long-term durability and protection. With the argon-insulated glass, the energy efficiency of these windows will be dramatically improved as well.
