Residential Attic Services in Watertown, WI

Our professional team of attic specialists will improve the insulation and ventilation in your attic! All estimates and consultations are FREE!

A properly insulated and ventilated attic will not only reduce and minimize the heat in your attic, it will also make your home’s air quality healthier while making your home more energy-efficient, saving you tons of money on utility bills! We provide an insulation inspection and ventilation inspection with every free roofing consultation to make sure the issue isn’t coming from the attic. When the attic isn’t ventilated properly, the roof gets “prematurely cooked to death.” The attic needs proper continual airflow where cool fresh air comes in and hot moist air goes out.

We Ventilate the Roof to:

  • Reduce and minimize heat
  • Reduce moisture and humidity
  • Keep the heat out of the attic and keep it cool year-round
  • Required for shingle warranty from manufacturer

Your roof will last years longer if ventilation and insulation issues are resolved within the attic.
