Signs You Should Replace a Commercial Roof

  • Widespread or Recurring Leaks:
    When water intrusion occurs in multiple locations or continues despite repeated repairs, it often indicates system-wide failure rather than isolated damage.
  • Extensive Membrane or Surface Deterioration:
    Seam failure, membrane separation, surface cracking, or saturated insulation reduces the roof’s ability to manage moisture effectively.
  • Frequent Repair History:
    Increasing repair frequency and cost often signal that replacement is more cost-effective than continued short-term fixes.
  • Poor Drainage or Structural Sagging:
    Aging commercial roofs lose flexibility, adhesion, and weather resistance even when damage appears minimal.
  • Roof Has Reached Its Expected Lifespan:
    Even without obvious damage, aging commercial roofs lose performance, flexibility, and resistance to moisture over time. 
  • Energy Inefficiency:
    Outdated roofing assemblies contribute to heat loss, moisture retention, and higher energy costs throughout the building.

Benefits of Replacing Your Commercial Roof

  • Long-Term Cost Control:
    A new commercial roof eliminates recurring emergency repairs, allowing owners and facility managers to budget with confidence.
  • Improved Building Protection:
    Modern roofing systems are designed to withstand Washington’s frequent rainfall, wind-driven moisture, and seasonal temperature fluctuations.
  • Increased Energy Efficiency:
    Updated insulation and reflective membranes help stabilize interior temperatures and reduce HVAC strain.
  • Code Compliance & Safety:
    Replacement ensures the roofing system meets current building codes and safety standards, reducing liability exposure.
  • Added Property Value:
    A newly replaced commercial roof strengthens property value, improves tenant confidence, and supports long-term investment goals.

Interstate Roofing provided an unprecadented level of professionalism and valve during our re-roofing project. From the sales representative to the project manager to the on-site job foreman, all individuals were courteous and respectful towards our property and family. Their bid price was not the lowest nor the highest, but we feel it represented the best valve for the services received. This was not a "one-off" experience, as over 25 homes in our neighborhood have used their skills in the last few years. Highly recommended!

Great service for commercial leak

We were very lucky to have Interstate Roofing come out to fix a commercial building flat-roof leak that an HVAC company made while installing a new heat pump vent.

This is the second house I have used Interstate Roofing for and like the first time they did an amazing job! My roof job was done by two teams (different roof types) and both Superintendents were great at keeping me updated with things they found during tear down and answering my questions. The roofing team for the pitched part of the roof were great at keeping the place cleaned up and were super friendly!
