Gz Exteriors | Roofing Services in Trenton, NJ 08610

Common signs in our area include higher-than-usual energy bills, visible mold or mildew in your attic, peeling interior paint, or a musty smell. Moisture trapped in insulation loses its effectiveness and can lead to structural damage. We recommend a professional inspection, especially before winter, to assess your attic ventilation and insulation integrity.

Those black streaks are typically Gloeocapsa magma algae, which thrives in Trenton's humid climate. It feeds on limestone in asphalt shingles. While not always structurally damaging, it shortens roof life and looks unsightly. We use a safe, low-pressure cleaning solution to remove the algae and can apply a zinc or copper strip treatment at the roof's peak to prevent regrowth.

Absolutely. Proper attic ventilation is key for Trenton roofs. It reduces heat and moisture buildup that degrades insulation in winter and creates the damp, warm environment algae love in summer. Our service includes evaluating and optimizing your roof's ventilation system, which is a proactive solution that addresses both common local issues.
