How To Tell If Your Attic Insulation Is Bad

Allstate Exteriors • September 28, 2020

“Bad” encompasses so much. A battery can be bad; a mischievous kid can be bad, but not bad the way potato salad goes bad. What about attic insulation? How many ways can your home’s attic insulation be bad? We know at least four ways your attic insulation could be bad. We also know how to fix it. 

Age

Ah, those carefree days, decades ago, when homebuilders constructed homes with little or no attic insulation. If they did insulate the attic, they often put down some minimal roll of the cheapest stuff available.  Old insulation may not necessarily be bad insulation, but it is unlikely to be great insulation. Having a roofer examine your attic insulation is a good first step toward diagnosing insulation that has just grown too old to do the job. 

Water

Leaky roofs have to send the water somewhere, and sure as gravity keeps tugging, water keeps dripping. It drips onto your insulation, dampening it. When insulation becomes damp, it loses the air pockets that make it effective. The insulation collapses, the paper backing on batts gets soggy, and the whole mess can lead to decay, rot, mold, and mildew. Damp insulation is bad insulation. 

Thin

You can buy R-13 batt insulation. It’s thin, mostly ineffective, and cheap. It is better than no insulation, but not by much. The plain fact is, the higher the R-value of your attic insulation, the lower your energy bills. Thin insulation is bad insulation. Better than thin, low R-value batts is blown-in fiberglass insulation. It reaches all nooks and crannies, it can be piled high as needed, and it provides full coverage. 

Mold

Bad insulation may not go bad all on its own. Sometimes it is the innocent victim of bad influences, like mold and mildew. Stinky, allergen-filled mold can fester in your attic insulation and lead to health problems for your whole family. Moldy insulation is bad insulation and should be removed by a mold remediation expert.

When you live in a place as beautiful and storm prone as Cape Coral, FL , your roof isn’t just another part of the house. It’s your first and most vital line of defense against Florida’s blazing sun, high humidity, and hurricane season downpours.

Why Roofing in Cape Coral Requires Specialized Expertise Cape Coral isn’t just another Florida city, it’s a unique community with specific architectural styles, salt air exposure from the Gulf, and frequent tropical weather patterns.

Real Results: Recent Roofing Projects in Cape Coral We’ve recently completed several roofing projects in Cape Coral that highlight the scope of our expertise and the quality we bring to each job. One standout job took place in the Rose Garden neighborhood. The homeowner reached out after repeated leaks from their 20-year-old tile roof. After a comprehensive inspection, we recommended a total tear off and reinstallation using high end barrel style clay tiles that match the home’s Mediterranean style. The result? Not only does the roof now provide superior water resistance and wind protection, but it also enhances the curb appeal of the entire property. You wouldn’t believe the transformation, and the homeowner couldn’t be happier. In another project over in Southwest Cape Coral near Cape Coral Parkway, we installed a modern metal roofing system for a homeowner looking to increase energy efficiency.
