Arizona is an extremely hot place in the summer. The heat takes its toll on roofing materials. While your roof can last for decades eventually heat, rain, and UV damage will destroy it.
Below is information on how long each roofing material can last in Phoenix. Of course these are only general estimates. How long your roof will actually last depends on the quality of the installation and which materials were used. If you have discoloration, curling, or other forms of damage to your roof it will likely need repaired or replaced regardless of age.
Tile roofs can last between 50 to 75 years. The limiting factor with tiles roofs is the underlayment. Underlayments need to be replaced every 15 – 20 years in Phoenix. You can keep your existing tiles and only replace the underlayment. Doing so saves you a lot of money as you can reuse the tiles.
Shingle Roofs last between 10 – 30 years in Phoenix depending on the quality of the material on your roof. Regular 3 tab shingles last between 10 – 15 years in Phoenix. Architectural or dimensional shingles are a lot thicker and can last from 15 – 30 years. Architectural shingles are heavier and more expensive than standard shingles and come in more shapes and sizes.
You do not have to remove your existing shingles to add a new roof to your home. You can reroof or roof over your existing shingles if you only have one layer of shingles on your roof. This will save you a lot of money as otherwise you would have to pay removal and dumpster fees.
Foam roofs last between 15 – 25 years in Phoenix. The important factor is whether the foam roof was recoated five years after it was installed. If it was it can easily last 25 years. Foam roofs can be recoated numerous times as long as the foam underneath is in good shape and not damaged. If you can see yellow or orange foam on your roof or if there are large holes on it, then you will have to tear off the current foam to add new foam.
Other Types of Roofing
Single ply, built up, and modified bitumen roofing last between 10 – 20 years. Single ply roofing such as TPO, EPDM, and PVC will usually last the longest. Built up roofs can last indefinitely with proactive maintenance.
Increasing the Lifespan of Your Roof
You can increase the lifespan of your roof by clearing debris off of it and by getting it inspected annually. Annual inspections can reveal problems early. If you catch a problem early it may be easy to fix. Issues that have gone unaddressed will result in much larger repair bills due to water damage and potentially mold.
As part of your inspection look at trees near your house for signs of decay. If you find a decaying tree cut it down before the next monsoon so it does not fall on your roof.
We offer free inspections in all of Phoenix, including Scottsdale, Glendale, Gilbert, Tempe, Chandler, Mesa, Sun City, and Peoria.
