Resolved persistent leaks on this Bakersfield property's flat roof section that had been improperly patched multiple times. We identified the root cause - poor drainage causing water to pool around the HVAC equipment. After cleaning the surface, we rebuilt proper drainage slopes, reinforced the membrane seams, and applied a commercial-grade coating system. This comprehensive approach addresses the actual problem instead of just treating symptoms like previous repairs had done.

Fixed a troublesome leak at the siding-to-roof transition for this Sacramento homeowner. Years of improper sealing had allowed water to penetrate behind the siding and rot the underlying wood. We replaced the damaged materials, installed proper step flashing along the entire junction, and sealed everything with high-performance waterproofing. This repair not only stops the leak but prevents future structural damage that would have been much costlier to fix.

Resolved a persistent chimney leak for a Bakersfield homeowner that had stumped previous contractors. We identified that the original builder had used inadequate step flashing and relied too heavily on caulking. Our team installed proper counter flashing that's mechanically fastened to the brick and integrates correctly with the roof system. This permanent solution creates a true waterproof barrier that won't fail during heavy rainfall or require annual maintenance.
