For persistent issues, we can discuss roofing solutions designed to resist future algae growth, helping protect your Cranston home.

Proper preparation is critical for paint to last through our seasonal changes. Our process includes a thorough inspection for wood rot or masonry cracks, power washing to remove mildew and old flaking paint, careful scraping and sanding, and the application of high-quality primers and sealants. We time projects to avoid painting in extreme humidity or cold, ensuring the best possible adhesion and durability for your Cranston home.

Yes, chimney flashing leaks are a frequent repair we handle. The problem often occurs where the flashing meets the brick or roof deck. We remove the compromised sections, inspect the underlying roof and chimney structure for water damage, install new, properly fitted flashing with durable sealants, and integrate it seamlessly with your existing roofing system. This targeted repair helps prevent interior water damage and preserves the integrity of both your chimney and roof.
