Steps of a Roof Replacement


Your roof is comprised of many components. These components all work together to provide protection from wind, rain, UV rays, debris, and everything else! When your roof gets replaced, so does all those components! Here is a general roof replacement process:


  1. Complete removal of existing roofing.
  2. Evaluate roof decking for damage and repair if necessary. If there was previous leaking, the roof deck may have some rotted wood that will need to be replaced.
  3. Install Ice & Water Shield leak barrier in most vulnerable areas of roof. During times of snow and ice buildup on roof, this shield acts as an additional barrier to prevent water from penetrating roof.
  4. Install felt/synthetic underlayment. This protects against wind-driven rain that may blow underneath the shingles.
  5. Install starter shingles on the eaves of the roof. This helps prevent shingles from blowing off in windy conditions.
  6. Install the shingle you’ve selected for your home. With so many performance and style options, this is where you see those choices on your home.
  7. Install ridge ventilation and replace other roof ventilation components. An estimated 9 out of 10 homes do not have adequate roof ventilation. Proper ventilation will extend the life of your roof and lower your home’s heating and cooling expenses.
  8. Install ridge cap shingles over ridge ventilation and ridges of home.
  9. Replace pipe jack flashings.
  10. Clean-up and haul-away any debris.


Your home’s roof replacement process may vary depending on the need for additional items.
