How Long Does a Roof Last?

How Long Does a Roof Last?

Your roof is the one thing keeping you and your home protected from the elements. But it won’t last forever. After a few decades, your roof will start to deteriorate. Learn how long your roof will last. Then, find out how Portland roofing contractors can impact the lifespan of your roof.

The Average Lifespan of a Roof

How long will your roof last? Because there are so many types of roofing materials, there is no one answer to this question. If you have a slate roof, it could last 100 years or longer. Clay tile roofing is also very durable and lasts about 100 years.

As far as metal roofing goes, you’re a little more limited. Copper and other traditional metals last for about 50 years. Single-layered asphalt shingles only last for about 35 years, and wood roofs last for about 25 years.

In addition to considering the lifespan of the roofing materials, you should also think of the underlayment and battens. Your battens and underlayment often require replacement every 30 to 40 years.

What Impacts the Lifespan of a Roof?

The lifespan of your roof depends on many factors. Here are a few key factors that can impact how long your roof lasts:

1.Proper installation

The best way to get a long-lasting roof is to have it properly installed. When Portland roofing contractors install your roof, they need to do so carefully. There are certain steps that contractors use to help your roof withstand the elements.

If a contractor skips those steps, your rood won’t be sturdy.  No matter what type of materials you use, the rain and wind can damage your roof.

2.Attic Ventilation for a Shingle Roof

If you have a shingle roof, you need attic ventilation. Failing to ventilate your attic causes moisture to become trapped.

As that moisture builds up, it makes a breeding ground for mold and mildew. The result is a rotting roof. Once the rot sets in, it won’t be long before you need to replace it.

3.Using the Right Materials

If you use the right materials for your roof, it will last longer. For example, treated wood stands up better to time than untreated wood.

4.Your Climate

If you live in a harsh climate, your roof could have a short lifespan. Unfortunately, the extreme temperature fluctuations of Portland can wreak havoc on your roof. It means that you might need to repair or replace your roof sooner than you would in another climate.

5.Getting Roof Inspections and Maintenance as Necessary

Your roof can withstand quite a bit. However, it’s not indestructible. Over time, it needs a little TLC. You need regular roof inspections and regular maintenance to help your roof last.

If a contractor notices an issue with your roof during inspection or maintenance, he can resolve the problem. You can catch an issue early to prevent the need for major costly repairs. In fact, you can lengthen the lifespan of your roof with some regular maintenance.
