How Long Do Metal Roofs Last?

Metal roofing offers easy installation, value for money and numerous other benefits. Available in various beautiful styles, they provide maximum wind resistance and are energy efficient. The low weight of the roofing materials helps to preserve the structural integrity of your building. However, the most promising characteristic is its durability. You can trust Trudel & Sons Roofing Ltd, which has over 35 years of experience, for quality roofing materials, installation and maintenance in GTA.

 

Different Types of Metal Roofs and Their Durability


Factors such as the weather at your place and the workmanship during installation also affect the lifespan of your roof. Overall, metal roofing can last for more than 50 years. Most of the products are warrantied for up to 40 years. In comparison, asphalt shingles last for about 23 years and single-ply lasts for around 20 years.


The total cost for roof installation depends upon the material used and the labour costs. Metal roofs can mimic expensive styles such as shake, slate, wood, shingles and clay tiles. Here are the different types of metal roofs and their durability:

 

• Steel Shingles and Shakes – High-end steel systems are better as they don’t need battens or strapping for installation and the panels can be interlocked with each other. A galvanized steel roof with PVDF finish has a better life expectancy and may be slightly expensive.

 

• Aluminum Shingles and Shakes – These are available with concealed fasteners, interlocking panels and PVDF coatings. You can use reflective pigments in the paint so your roof deflects heat rays. You can even install aluminum shingles and shakes over your existing roofing without much hassle. These shingles don’t require any maintenance and as aluminum doesn’t rust, reroofing is not necessary.

 

• Standing Seam Metal Roofing – These consist of a metal panel system featuring a vertical leg and a board, which is the flat area between the two legs or seams. So, the seams rise above the panel’s flat area and the fasteners are concealed. They are available in steel and solid aluminum with PVDF coatings. The costs vary depending upon the type of metal chosen.

 

• Exotic Metal Roofing – These are mill finished zinc or copper seam panels or shingles. They are often used in churches or historic buildings owning to their exotic appeal. These products are priced higher and need a certain level of expertise for installation.

 

Why Does Metal Roofing Have A Long Life?

A metal roof is not just a series of steel panels but a system made of clips and framing membranes. This arrangement increases the durability of the roofs.
The clips hold the roof panels to the structural members and leave enough space for the metal to expand and contract when seasons change. Factory punching makes sure the panels are properly aligned. Splices are staggered to avoid exposed seams and leak points. The fasteners are concealed inside the curbs to mitigate the danger of potential leaks.

 

Whether there are high winds or a severe hailstorm, there are fewer chances that the metal roof will blow away. The panels are interlinked and are very strong. They are also resistant to impact and fire. In case you experience an earthquake, the roof clips allow movement, where the metal may buckle but not splinter or shatter. Moreover, pests cannot feed on it and weaken it.

 

Metal roofing is highly sustainable. It can be 100 per cent recycled. Though the initial costs may be higher, maintenance charges are minimum. This increases your savings.
