The Hot Mop Specialists | Waterproofing & Roofing in Costa Mesa, CA 92627

For Costa Mesa homes, lifting roof flashing and valley leaks are often due to coastal weather and aging materials. We address these by carefully removing the compromised flashing, inspecting the underlying deck for moisture damage, and installing a new, code-compliant hot mop waterproofing layer before replacing the flashing. This creates a seamless, watertight barrier that prevents future leaks and protects the roof structure, which is crucial for our local climate.

Our deck construction starts with proper waterproofing from the ground up using the hot mop method, especially critical for outdoor spaces. We pre-slope the substrate to ensure water drains away from your home, preventing pooling and structural rot. Combined with durable materials and craftsmanship, this approach not only creates a beautiful deck but also one that is built to last and protect your Costa Mesa home from moisture damage for years to come.

Our guarantee stems from strict adherence to building codes and our specialized hot mop technique. For example, all our shower pans are pre-sloped at 1/4 inch per foot as required, and we meticulously detail every seam and corner. We use this same precision for decks and roofs. By doing the job correctly the first time with high-quality materials and proven methods, we ensure a watertight installation that will meet or exceed the inspector's requirements, giving you complete peace of mind.
