How Often Should You Change Your Roof Insulation

Have you noticed your gas or electric bills creeping up every year.

How often should you change your roof insulation.

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. Often these temperature changes signify shifted or rotted insulation in the attic letting ambient air into your home. Galvalume or metal roofing materials have an estimated lifespan of 30 to 45 years and concrete tile generally lasts between 30 and 50 years. Foam insulation can settle after a year and may need to be replaced to keep it fluffy and insulating properly.

Higher energy bills than usual. Standard insulation starts to degrade and start peeling from walls after about 15 years. You should get a roofing contractor to perform a roof inspection every year to see what condition your roof is in and tell you if it needs to be replaced.

Insulation should also be replaced in some cases sooner than 15 years if it is no longer doing its job properly. Sometimes simply resetting the insulation fixes the problem but oftentimes it requires replacement. Do you have icicles on your eaves and gutters or ice collecting on your roof. 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.

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