Underlayment Replacement

Roof Underlayment Replacement for Tile Roofing Systems

New roof
Interior repairs

The underlayment is one of the most important protective layers in a roofing system. Installed beneath tiles, shingles, or other roofing materials, it acts as a waterproof barrier that shields the roof deck and your home’s interior from moisture intrusion. Over time, this hidden layer can deteriorate due to age, heat exposure, and weather conditions.


Sunstone Roofing provides professional underlayment replacement services throughout San Diego County, helping homeowners restore the waterproof protection beneath their roofing materials without always requiring a full roof replacement. When underlayment begins to fail, replacing it promptly can prevent leaks, structural damage, and costly interior repairs.

Our Underlayment Replacement Process


Sunstone Roofing follows a careful process to ensure underlayment replacement is completed correctly while preserving the integrity of your roof.


Roof Inspection and Evaluation

We begin by inspecting the roofing system to determine the condition of the underlayment and identify areas where moisture may be entering the roof structure.


Tile or Roofing Material Removal

To access the underlayment layer, the outer roofing materials such as tiles or shingles are carefully removed and set aside when possible.
