How Long Will A Galvanized Metal Roof Last

Corrugated metal roofs can typically last much longer than a traditional asphalt shingles roof.

How long will a galvanized metal roof last.

Closing thoughts on steel roofing. Metal roofs can be as much as two or three times more expensive than other roofing materials. Corrugated and ribbed metal panels are made of metal sheets normally g 60 or g 90 better galvanized steel but can also be aluminum and stainless steel sheets that are shaped into ridges or waves. This is especially true when you invest in a metal roof engineered from galvanized steel.

Metal roofing runs the gamut of price and quality starting around 115 per square for standing seam panels in aluminum or steel. Unlike other roofing materials such as asphalt with kynar 500 steel roofing there is no need for ongoing maintenance to ensure best long term appearance durability and longevity. Galvanized steel which is created by using a soft layer of zinc to protect the inner layers is the most common type of steel roofing. Metal roofs can be noisy especially during a heavy rain or hailstorm.

While the life of a metal roof is much longer investing in a metal roof only makes sense if you plan to stay in your home long enough to enjoy the cost benefits.

Metal roofs are attractive durable and can last up to 70 years. The corrosion resistance of hot dip galvanizing varies according to its surroundings but generally corrodes at a rate of 1 30 of bare steel in the same environment.

A metal roof is more than a series of steel panels. Roof clips securely hold the roof panels to the structural members but leave enough wiggle room for the panels to move with the expansion and contraction caused by the temperature. This means that a typical metal roof will last about 3 7 times longer than a typical asphalt shingles roof which usually needs to replaced every 12 17 years. Hot dip galvanizing hdg is often used to protect steel from corrosion in some of the harshest environments imaginable yet it provides maintenance free longevity for decades.

Noise is usually not a factor if you are installing a steel roof over asphalt. Galvanized steel and galvalume offer excellent value cost over their service lifespan. Metal roofs such as aluminum or steel shingles can last for 50 years and often longer while copper and zinc roofs can often last well over 100 years. It is an entire system made up of clips and framing members that all impact how long the roof will last.
