We perform extensive planning and mitigate risks for minimal downtime. ![bay-area-roof-leak-repair-1](https://raindefense.com/hubfs/RainDefense/bay-area-roof-leak-repair-1.jpg) ## **Why Rain Defense's Expertise Makes All the Difference** The roof is the most critical part of the building envelope. It is a large capital expense, and poor design or installation can lead to large financial losses. So selecting the right system is critically important. Rain Defense is highly skilled in a wide range of roofing systems. PVC, TPO, EPDM, Mod Bit, Urethane, Polyurethane, Acrylic, Silicone, Tile, Shingles and more; there are a dizzying array of systems available for your building today and we understand them all. Most roofing contractors only do a few types of roofing systems. This limited range of skill means they must offer you “their system”, regardless of what is best for your roof. However, Rain Defense’s broad range of experience allows us to recommend the system that is right for your building. By always offering the right roofing system for our clients, we have built long relationships with hundreds of customers based on trust. ![Low-Slope-Roofing-1](https://raindefense.com/hubfs/RainDefense/Low-Slope-Roofing-1.jpg) ## **Low Slope Roofing** - SinglePly (Duro-Last, IB, GAF, Carlisle) - Modified Bitumen (Certainteed, GAF, PolyGlass) - Urethane & Polyurethane (GCMC, Gaco) - Pedestrian Roof Decks (Gaco, WestCoat) ![Restoration-Coatings-1](https://raindefense.com/hubfs/RainDefense/Restoration-Coatings-1.jpg) ## **Restoration Coatings** - Acrylic (KM, Gaco, GCMC) - Silicone (KM, Gaco, GCMC) - Urethane (GCMC, Tremco, NeoGard) ![Steep-Roof-Waterproofing-Work-Rain-Defense-San-Francisco-2](https://raindefense.com/hubfs/RainDefense/Steep-Roof-Waterproofing-Work-Rain-Defense-San-Francisco-2.jpg) ## **Steep Slope Roofing** - Asphalt Shingles (Certainteed, GAF) - Tile Roofing ![Miscellaneous-Accessories-1](https://raindefense.com/hubfs/RainDefense/Miscellaneous-Accessories-1.jpg) ## **Accessories** - Gutters, Drains & Downspouts - Drainage Solutions - Roof Insulation - Skylights - Roof Hatches - Access Ladders - Equipment Curbs - Sight Screens - HVAC Ducting Waterproofing ![Oaks-Theater-cool-roofing-contractor-1](https://raindefense.com/hubfs/RainDefense/Oaks-Theater-cool-roofing-contractor-1.jpg) ## **What is Cool Roofing & Title 24?** Rain Defense installs Title 24 compliant Cool Roof Systems. These systems not only seal your building against the elements but reduce energy costs and help the environment. Traditional asphalt roofing has provided sound rainproofing since 1847. They are durable, easy to repair, and last years with regular maintenance, but they tend absorb heat rather than reflect it back up into space because of their basic chemistry and dark colors. A Cool Roof system naturally moderates the building’s temperature by reflecting sunlight that would otherwise cause a lot of heat gain on the building. If you would like to know the Title 24 requirements for our specific project, visit [Title24Part6.com](https://title24part6.com) for a comprehensive checklist.  ![HOA-roof-reconstruction-maintenance](https://raindefense.com/hubfs/RainDefense/HOA-roof-reconstruction-maintenance.jpg) ## **Expertise in Large-Scale Projects:** Comprehensive Rainwater Control & Roofing Solutions ### Large Projects Specialization Whether you need a simple leak repair or an full tear-off roof system valued at over $1M, we can deliver.
