Triumph Roofing & Exteriors Company in San Diego, CA 92117

Stopping moss regrowth requires a two-step approach. First, our team performs a professional, non-damaging removal. Then, we apply a preventative zinc or copper-based treatment along the roof ridge. These strips create a solution that washes over the shingles with rain, creating a long-lasting barrier against moss and algae common in our humid coastal climate. Regular gutter cleaning to prevent moisture buildup is also key.

San Diego's temperature swings and occasional heavy rains put constant stress on skylight seals and flashings. The materials expand and contract, eventually cracking or pulling away. Most leaks occur at the flashing perimeter or where the skylight curb meets the roof deck. Triumph Roofing specializes in pinpointing these failure points and performing precise repairs or re-flashing with high-quality, UV-resistant sealants designed for our local conditions.

It depends on the extent of the damage. Moss holds moisture against shingles, causing granule loss and wood rot in the deck underneath. Our thorough inspection will assess the shingle integrity and the condition of the roof deck. Often, localized repairs and replacement of affected sections are sufficient if caught early. We always prioritize repair when possible, but we'll give you an honest assessment if the damage from prolonged moss growth has compromised the roof's structure.
