How Often Should You Change Your Roof Insulation

You can expect architectural asphalt shingles to last a bit longer at an average of 25 to 30 years.

How often should you change your roof insulation.

Galvalume or metal roofing materials have an estimated lifespan of 30 to 45 years and concrete tile generally lasts between 30 and 50 years. Proper attic insulation can help keep frozen precipitation from building up. While some insulation is built to last years there are times when you need to replace your insulation or add on more insulation to it. Sometimes simply resetting the insulation fixes the problem but oftentimes it requires replacement.

An average roof needs to be replaced after 15 50 years depending on the material used ventilation and climate factors like humidity heat and cold. Most roofs with asphalt shingles will last an estimated 15 to 20 years. Often these temperature changes signify shifted or rotted insulation in the attic letting ambient air into your home.

If you have an older home chances are the attic insulation is the same insulation that was installed when the house was built. Do you have icicles on your eaves and gutters or ice collecting on your roof. Standard insulation starts to degrade and start peeling from walls after about 15 years. Foam insulation can settle after a year and may need to be replaced to keep it fluffy and insulating properly.

Insulation should also be replaced in some cases sooner than 15 years if it is no longer doing its job properly.
