Signs You Should Replace a Commercial Roof

  • Widespread or Recurring Leaks:
    When leaks appear in multiple areas or continue after prior repairs, it often indicates the roofing system has reached a failure point where spot repairs are no longer effective. 
  • Extensive Membrane or Surface Deterioration:
    Large-scale cracking, blistering, seam separation, or material breakdown compromises the roof’s ability to shed water and maintain a watertight seal. 
  • Frequent Repair History:
    If repair calls are becoming more frequent or costly, replacement is often the more economical option compared to ongoing short-term fixes. 
  • Poor Drainage or Structural Sagging:
    Persistent ponding water, clogged drainage paths, or visible deck deflection can signal underlying structural or insulation issues that repairs alone cannot resolve. 
  • Roof Has Reached Its Expected Lifespan:
    Even without obvious damage, aging commercial roofs lose performance, flexibility, and resistance to moisture over time. 
  • Energy Inefficiency:
    Older roofing systems often lack modern insulation values and reflective properties, leading to higher heating and cooling costs across the building.

Benefits of Replacing Your Commercial Roof

  • Long-Term Cost Control:
    Replacing an aging commercial roof eliminates the cycle of reactive repairs, giving owners and property managers predictable costs and fewer unexpected maintenance disruptions. 
  • Improved Building Protection:
    New commercial roofing systems are engineered to handle Oregon’s heavy rainfall, wind exposure, and seasonal weather, providing consistent protection against moisture intrusion and structural damage. 
  • Increased Energy Efficiency:
    Modern insulation assemblies and reflective roofing membranes help regulate interior temperatures, reducing heating and cooling demands across large commercial buildings. 
  • Code Compliance & Safety:
    A full roof replacement brings the system up to current building codes and safety standards, reducing liability risks and supporting long-term occupancy requirements. 
  • Added Property Value:
    A new commercial roof improves asset value, strengthens resale positions, and provides reassurance to tenants, owners, and investors alike.

Excellent service! Chaba came out and gave us a quote. He was very knowledgeable about roofing options and different products. He wasn't pushy which we appreciated. His crew did a great job in less time than other companies had quoted and they made sure to clean up after each day. We have already recommended Chaba and his company to others.

Thank you to everyone at Interstate Roofing for your professionalism, high-quality work, and for making our home look great! I have to give a huge shout out to Oscar who took complete ownership over the project and made it seemingly his mission in life to make sure everything was just right and doing whatever it takes to get there. Enough can't be said about the value of people like Oscar in a company!

We had an excellent experience with Interstate roofing. Oscar and Franco did the 2 day job. Oscar was informative and professional, taking pictures of the before and after. They blew off leaves and washed some of the siding for us. Oscar let me know every step and how long it would be and they cleaned up nicely when they were done. They sent out their inspector after the job was completed to make sure everything was done correctly. Very thorough.

Interstate Roofing made, what I thought was going to be a difficult, trying experience, into something that I can only call wonderful. Their quote was very detailed and every question my wife and I had was answered. I have encountered a few roofers and am usually left with doubt and concerns. Not with Mr. Gabel. He ensured that everything was completed properly and went above and beyond to make sure my family was inconvenienced as little as possible. I highly recommend Interstate and Mr. Gabel!!
