Before providing recommendations, options and estimates—we first must determine the true extent of your roof system's repair, replacement, waterproofing or maintenance needs. At Madsen Roofing & Waterproofing, Inc., we diligently perform an inspection of your existing roof or building envelope. 

  1. Upholding rigorous industry standards, we generally extract at least two samples of the existing membrane, all the way to the original roof deck, including components and insulation. We also review all pertinent information: roof specifications, blueprints, history, and warranties.
  2. Next, we make detailed written recommendations with your personalized options and specify budgets for each option. With vast expertise in commercial roofing and building envelope materials, we provide customers multiple roof system options that are appropriate for each project. 
  3. If you accept our estimate, we professionally execute the work to the highest level of service and craftsmanship, ensuring your roofing or waterproofing investment has the greatest longevity possible.
