SJ Company | Roofing Services in Modesto, CA 95357

Our roof repair service in Modesto focuses on lasting solutions, especially for common local issues like moisture in roof insulation or lifting flashings. We use the Western Colloid cold process system, which is applied directly over your existing roof material—whether it's BUR, Modified Bitumen, or Metal. This seamless application seals leaks, reinforces weak areas, and restores waterproof integrity. For metal roofs, our reconditioning process specifically addresses seams and fasteners to prevent future leaks, all backed by our ten-year warranty.

After our initial ten-year warranty expires, we offer a unique rewarranty program at about one-third the original cost. We return to inspect the roof, clean the surface, make any necessary patches, and then reapply fresh layers of Western Colloid emulsion and a reflective silver-white coating. This process renews the warranty for another ten years, extending the life of your roof and protecting your investment. It's a service born from our long-term commitment to our Modesto neighbors, many of whom are now on their third cycle with us.

Absolutely. Moisture trapped in flat roof insulation is a common problem in our area due to temperature swings and aging materials. Our specialized cold process application seals the entire roof surface, preventing further water intrusion. The system is designed to breathe, allowing trapped moisture to escape over time while creating a new, monolithic waterproof barrier. This stops the damage cycle, improves energy efficiency with our reflective coating, and is backed by our ten-year warranty for your peace of mind.
