Attic Insulation & Ice Dam Prevention Go Together
Attic insulation and ice dam prevention are one job in a Saginaw winter. Ice dams form when warm air leaking from the house heats the roof deck, snow melts, runs down to the cold eaves and refreezes. Water then backs up under shingles and into ceilings and walls. Adding insulation alone does not fix it if warm air is still escaping through gaps. The fix is to seal, ventilate and then insulate.
Seal the bypasses
Plumbing stacks, chimney chases, light boxes, bath fans, top plates and the hatch are the usual leaks. We close them with foam, sealant and fire-rated materials around chimneys and flues.
Keep the vents open
Baffles at the soffits keep insulation from blocking the intake vents, so cold air can wash the underside of the roof and keep it cold.
Add depth
Michigan's updated residential energy rules set R-60 for ceilings in zones 5 through 7, and ENERGY STAR recommends R-60 for an empty zone 5 attic and R-49 added over 3 to 4 inches of existing insulation. Blown-in cellulose or fiberglass is usually the most economical way to reach those levels.
When foam fits
Cathedral ceilings, kneewall attics and low-slope roofs without room for venting often need closed-cell foam against the roof deck. We tell you when that is the case.

Attic Insulation & Ice Dam Prevention Questions
Will more insulation stop my ice dams?
Only if the air leaks are sealed and the roof is vented. Insulation without sealing often leaves the problem.
What R-value should my attic have?
Michigan's updated code sets R-60 for new ceilings in zone 5; ENERGY STAR recommends R-49 to R-60 for existing homes depending on what is there now.
What about frost on attic nails?
That is warm, moist air leaking into a cold attic. Sealing the bypasses is the fix.
Does Consumers Energy offer an attic rebate?
Its chart lists $125 to $200 for at least 500 square feet of attic, depending on final R-value and your service type. Check the current chart.
