How Often Should You Change Your Roof Insulation

This is an updated version of a story originally posted on oct.

How often should you change your roof insulation. Standard insulation starts to degrade and start peeling from walls after about 15 years. Proper attic insulation can help keep frozen precipitation from building up. Do you have icicles on your eaves and gutters or ice collecting on your roof. Have you noticed your gas or electric bills creeping up every year.

Galvalume or metal roofing materials have an estimated lifespan of 30 to 45 years and concrete tile generally lasts between 30 and 50 years. Insulation should also be replaced in some cases sooner than 15 years if it is no longer doing its job properly. You can expect architectural asphalt shingles to last a bit longer at an average of 25 to 30 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.

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. Most roofs with asphalt shingles will last an estimated 15 to 20 years. 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. 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.
