Yes, those dark streaks are likely algae growth, a common issue in our humid Long Island climate. While often mistaken for mold, it can degrade your shingles over time. SW Roofs can assess the extent of the growth and perform a professional cleaning or apply treatments to inhibit future growth. For more severe cases where shingles are compromised, we can discuss repair or replacement options during our detailed inspection.

Our inspection is a thorough evaluation of your entire roofing system. We examine the shingles or membrane, flashing (especially around chimneys and vents), gutters, and the interior attic space for signs of leaks or moisture. Following the inspection, you'll receive a clear, written report with photos that details our findings. This report will explain any necessary repairs, provide recommendations for maintenance, and outline your options, so you can make an informed decision with no pressure.

Absolutely. We are experienced in Torch Down Roofing, which is a highly effective, durable method for flat and low-slope roofs. This system involves heating a modified bitumen membrane with a torch to create a seamless, watertight bond. It's particularly well-suited for our New York weather, offering strong resistance to temperature fluctuations and water pooling. During a consultation, we can assess if Torch Down is the right solution for your specific flat roof application.
