Rix Roofing | Building Supplies & Roofing in Middletown, PA 17057

In our climate, flashing can separate due to thermal expansion and contraction, high winds, or improper initial installation. At Rix Roofing, we fix this by first removing the old, compromised flashing. We then install new, high-grade metal flashing, sealing it with professional-grade sealants and securing it properly to the roof deck and surrounding surfaces to create a durable, watertight barrier that withstands local weather.

In Middletown, those dark streaks on north-facing or shaded roof slopes are typically Gloeocapsa magma algae, which feeds on limestone in asphalt shingles. The best treatment is a professional soft wash with an EPA-approved, algae-specific solution. We avoid high pressure to protect your shingles. For long-term prevention, we can install zinc or copper strips at the roof ridge, which release ions that inhibit future algae growth with each rain.

Absolutely. Proper gutters are crucial. Clogged or misaligned gutters cause water to back up under the roof edge and behind flashing, accelerating separation. Overflowing water also keeps roof surfaces damp, promoting algae growth. Our gutter installation, cleaning, and repair services ensure water is channeled away efficiently, protecting your roof's edge and helping to keep it drier, which supports the health of your entire roofing system.
