How Can I Tell If I Have An Ice Dam At My House?

Ice dams can be hard to see from the ground. Here are a few ice dam signs:

  • Gutters that cannot drain
  • Snow melting on the peak of the roof, but not the sides
  • Exterior walls with ice formation
  • Icicles on the edge of your roof

Do I Have To Get All New Insulation If I Have Ice Dams?

 Some ice dams lead to wet insulation and attic mold growth.  In this case, new house insulation is necessary.  In other cases, tweaks to ventilation and attic air sealing can occur. It’s important to know that something as simple as a bath fan venting into the attic can cause ice dam formation.

Can I Have Ice Formation On My House Even If My Insulation And Ventilation Are Adequate?

Roof icicles can happen as part of Wisconsin and Minnesota’s freeze/thaw cycle.  It’s important to know that not every ice dam has icicles.  In the same way, roof icicles, do not always signal an ice dam.

"Jason and the insulating crew did a great job. I told Jason it looked like nothing was done when he finished cleaning, which is a very good thing.  The insulating crew did have a difficult time working under the bay window. They usually hold their spray gun about 2 ft. away from the surface. In our location, they only had a foot at the most. So, there was a lot of blowback, clean-up, and additional layers to get the final result."

"They were contracted to insulate the garage ceiling which they did in a two-step process with both foam and blown-in insulation. They then returned to put up new gutters facia and soffits in a two day process that was professional, neat , and used materials economically."

"Had Lindus blow in foam insulation into attic, what a difference it’s made! The house is noticeably warmer in the winter and my furnace is not running nearly as much as before. I know it will also help keep the house cool in the summer heat. They also installed some new windows and exterior trim. Everything turned out really well. Corey Hessler was fantastic in dealing with from start to finish and answered all my questions. Everyone I dealt with from Lindus, especially Corey, were kind and professional. In today’s day and age you get what you pay for. Lindus really delivers!"
