Our Specialized Roof Deck Waterproofing Membrane Installation Services
We offer comprehensive waterproofing solutions designed to protect your roof deck from moisture damage and extend your roofing system's lifespan.
TPO Membrane Installation
TPO membrane installation provides single-ply waterproofing protection with excellent UV resistance and energy efficiency benefits. Our certified technicians properly prepare the roof deck surface and install TPO membranes using heat-welded seams for maximum durability.
We ensure proper drainage slopes and membrane overlap to prevent pooling water and potential leak points. TPO membrane systems typically last 20-30 years with minimal maintenance requirements when professionally installed.
Modified Bitumen Waterproofing
Modified bitumen waterproofing systems combine traditional asphalt with modern polymer technology for superior flexibility and weather resistance. We apply multiple layers using torch application or cold adhesive methods depending on your specific roof conditions and requirements.
Our installation process includes proper primer application and careful seam sealing to create a monolithic waterproof barrier. Modified bitumen systems provide excellent puncture resistance and can withstand thermal cycling common in Southern California climates.
EPDM Rubber Membrane Systems
EPDM rubber membrane systems offer long-lasting waterproofing protection with proven performance in diverse weather conditions. Our installation process includes proper insulation placement, membrane positioning, and mechanical fastening or adhesive application as required.
We pay special attention to penetration sealing and edge details to ensure complete water exclusion from your roof deck. EPDM systems provide exceptional durability and can last 25-30 years with proper installation and maintenance.
Liquid Applied Membrane Coatings
Liquid applied membrane coatings create seamless waterproofing barriers that conform to complex roof shapes and penetrations. We prepare surfaces through thorough cleaning and priming before applying multiple coating layers with reinforcing fabric at critical areas.
Our application techniques ensure uniform thickness and proper curing for optimal waterproofing performance. Liquid membrane systems offer excellent adhesion properties and can be applied over various substrate materials for versatile waterproofing solutions.
Professional Waterproofing Installation Process
Our systematic approach ensures every roof deck waterproofing membrane installation meets the highest standards for performance and durability.
Comprehensive Roof Deck Assessment
We begin every project with a thorough roof deck inspection to identify structural issues, drainage problems, and surface preparation requirements. Our assessment includes moisture testing, deck condition evaluation, and identification of penetrations requiring special waterproofing attention.
Surface Preparation and Priming
Proper surface preparation is critical for waterproofing membrane adhesion and long-term performance in all installation projects. We clean roof decks thoroughly, repair any structural defects, and ensure proper drainage slopes before membrane application.
Precision Membrane Installation
Our certified installers use manufacturer-approved techniques and equipment to ensure proper membrane placement and sealing. We carefully position membranes to minimize seams while ensuring adequate overlap and proper adhesion at all connection points.
Quality Assurance and Testing
We conduct comprehensive quality inspections throughout the installation process to verify membrane integrity and proper sealing. Our testing procedures include flood testing, where applicable, and electronic leak detection for critical waterproofing applications.
