Contractors installing ice and water shield on a residential roof

Four tips For estimating Ice & Water Shield on an insurance roofing job

Ice & Water Shield (IWS) is a code requirement in most locations to protect against water filtration resulting from the freeze-thaw cycle. The code states that IWS needs to be installed to cover two feet inside the exterior wall to protect the home. 

How much IWS do you need to order?

IWS is produced in three-foot rolls because most soffits are one foot. But when you’re ordering IWS, you need to account for your wall thickness and roof pitch as well. Wall thickness can be anywhere from 4.5 inches and larger, so you may need more material to make it two feet inside the exterior wall. The roof pitch also determines how much material will be needed. Roofs with a steep pitch may require up to four courses of IWS in order to reach 24 inches inside the exterior wall.

Tips to be on the same page with an adjuster:
  1. KNOW THE CODE
    • If IWS is not installed on the roof, it is more than likely required by code and can be supplemented.
    • Code also states the barrier is required anywhere that ice accumulates, such as valleys.

       

  2.  CARRY A CODE SHEET TO YOUR ADJUSTER MEETING
    When you’re discussing the code for the area, you can show them proof onsite. This will eliminate future supplements and make you look knowledgeable and prepared. It can also help save an adjuster time if he/she is from out of town.

     

  3. ONLY ASK FOR ITEMS YOU KNOW SHOULD BE APPROVED
    The code only covers heated buildings. So, unless the garage is heated, the code will not require IWS to be installed on the garage.

     

  4. TAKE PHOTOS
    If IWS is already installed on the roof, the insurance company will pay to replace it. Take a photo to prove it’s on the roof.
