Certification Advantages ## Great Systems Need Great Partners Rain Defense strives to install better systems than the competition. There are many factors that go into creating great roofing and waterproofing systems such as design and execution. Yet all the careful thought and hard work in the world will not succeed without excellent materials. Rain Defense has spent years developing close partnerships with key industry leaders to deliver superior systems. *Through a process of “Certification”, we are among an elite few contractors that can deliver superior roofing and waterproofing systems that outperform even the toughest expectations.* The many advantages of certification include … [Become a Partner](https://raindefense.com/contact-us) ## Qualified Applicators Another critical advantage of a System Certified Contractor is vetting. Where it is very difficult for a consumer to be sure a contractor is qualified to install a given system, a Manufacturer is keenly aware of the skill and care that a contractor applies to each job. ## “System” or “NDL” Warranties The most important advantage of our partnerships are Extended Warranties. Most materials carry a very basic defects warranty that doesn’t cover much. Extended Warranties are vastly more useful at covering your risks in the unlikely event of a system failure. They not only cover the materials but they cover labor too and many are also non-prorated. Any system you buy should at least offer an Extended Warranty for peace of mind. ## High Quality Technical Advice While many contractor’s feel they know it all, elite contractor’s rely on a pool of highly skilled professionals for advice and support. This type of partnership affords the contractor a much larger base of knowledge and experience to draw from; which inevitably leads to better solutions for the customer. ## Free Systems Design Consultants are a growing sector of the construction industry as the wide array of materials and methods continue to grow. Unfortunately, Consultants are VERY expensive. But a sound Manufacturer-Contractor Partnership can be used to provide the exact same services for free. Ask us how Rain Defense can help you save a lot of money by leveraging our Manufacturer Partnerships to professionally design your project at no additional charge. ## Pedestrian & Vehicular Waterproofing [![manufacturer-logo-westcoat](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/manufacturer-logo-westcoat.png?width=216&height=37&name=manufacturer-logo-westcoat.png)](http://www.westcoat.com/) [![manufacturer-logo-gacowestern](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/manufacturer-logo-gacowestern.png?width=195&height=42&name=manufacturer-logo-gacowestern.png)](http://www.gaco.com/) ## Roof Coatings [![emergency-roof-leak-repair-service-](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/emergency-roof-leak-repair-service-.jpg?width=268&height=100&name=emergency-roof-leak-repair-service-.jpg)](https://gaco.com/) [![manufacturer-logo-KM](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/manufacturer-logo-KM.png?width=67&height=70&name=manufacturer-logo-KM.png)](https://kmcoatings.us/) [![bay-area-roof-leak-repair-service](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/bay-area-roof-leak-repair-service.jpg?width=300&height=92&name=bay-area-roof-leak-repair-service.jpg)](https://www.tremcosealants.com/) [![roof-leak-repair-service-bay-area](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/roof-leak-repair-service-bay-area.jpg?width=224&height=100&name=roof-leak-repair-service-bay-area.jpg)](http://westerncolloid.com/) ## SinglePly Roofing [![IB_Roof_Systems-roof-leak-repair](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/IB_Roof_Systems-roof-leak-repair.jpg?width=300&height=66&name=IB_Roof_Systems-roof-leak-repair.jpg)](https://ibroof.com/) [![manufacturer-logo-versico](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/manufacturer-logo-versico.png?width=216&height=37&name=manufacturer-logo-versico.png)](https://www.versico.com/) [![Carlisle-Syntec-roof-leak-repair](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/Carlisle-Syntec-roof-leak-repair.jpg?width=300&height=74&name=Carlisle-Syntec-roof-leak-repair.jpg)](https://www.carlislesyntec.com/) [![manufacturer-logo-gaf](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/manufacturer-logo-gaf.png?width=68&height=60&name=manufacturer-logo-gaf.png)](http://www.gaf.com/) ## Modified Bitumen Asphalt & Shingle Roofing [![manufacturer-logo-certainteed](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/manufacturer-logo-certainteed.png?width=216&height=52&name=manufacturer-logo-certainteed.png)](http://www.certainteed.com/) [![PolyGlass](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/PolyGlass.jpg?width=335&height=100&name=PolyGlass.jpg)](http://www.polyglass.com/) [![bay-area-roof-leak-repair-service](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/bay-area-roof-leak-repair-service.jpg?width=300&height=92&name=bay-area-roof-leak-repair-service.jpg)](https://www.tremcosealants.com/) [![manufacturer-logo-gaf](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/manufacturer-logo-gaf.png?width=68&height=60&name=manufacturer-logo-gaf.png)](http://www.gaf.com/) ## Wall Siding [![manufacturer-logo-jameshardie](https://raindefense.com/hs-fs/hubfs/RainDefense/Manufacturers/manufacturer-logo-jameshardie.png?width=216&height=44&name=manufacturer-logo-jameshardie.png)](https://www.jameshardie.com/) ## Other Non-Certified Systems We Install -
