Repairing Vs Replacing An Old Asphalt Roof: How To Tell When It's Time To Let Your Old Roof Go

Posted on: 18 April 2018

Replacing your roof is an expensive venture for homeowners, and many wonder if they can simply repair their damage instead. While it's important to repair your roof whenever you notice damage, an asphalt roof has a limited lifespan. The asphalt and underlayment will both degrade over time. Old roofs will experience problems more frequently and eventually fail completely. Here are some questions to ask yourself when you're considering performing repairs or re-roofing your home entirely.

Are Shingles Breaking and Cracking?

Any cracked or broken shingles will let water into your home and must be replaced immediately to prevent mold and water damage. However, a single broken shingle doesn't necessarily mean that it's time for an entirely new roof. The important consideration is how often shingles are breaking or falling off. If you notice a lot of missing shingles, especially if they're in different areas of the roof, it's time to call a roofing installation professional to re-roof your home. The underlayment of your roof doesn't last forever — once it starts to degrade, shingles will be coming loose more frequently.

Are Your Shingles Worn Down?

Asphalt shingles wear down over time. The asphalt is degraded by ultraviolet light, which slowly makes it weaker. High winds will carry away bits and pieces of weakened asphalt off of the shingles. This will give the shingles on your roof a ragged, uneven appearance. It's easier to see if you take a pair of binoculars outside and use them to examine your shingles closely.

When the asphalt is entirely worn down, it exposes the underlayment. The purpose of the asphalt is to keep water away from your underlayment and your decking since neither are water-resistant. An old roof with worn shingles will quickly experience rot and water damage. If you notice a lot of worn shingles when you examine your roof, replace it before water starts getting into your home.

How Old Is Your Roof?

The maximum lifespan of an asphalt shingle roof is 25 years. Harsh weather conditions can reduce this lifespan. If you're in an area with few windbreaks around your home and regularly experience harsh storms, for example, your roof may not last for the full 25 years. If your roof is nearing the end of its useful life, it's time to replace it. However, if your roof is less than ten years old, it's a better idea to repair.

When your roof has reached the end of its useful lifespan, it's time to replace it. Neglecting to replace an old roof will eventually lead to rotted decking and water damage inside your home, both of which quickly outpace the cost of replacing your roof.

A Direct Guide To Roofing

Hi, my name is Scott, and as you search through this blog, you'll learn invaluable information concerning roofs. When reading the articles, you'll learn about roof repairs, roofing materials and what's new in the roofing industry. I didn't become interested in roofing until my roof started to leak. When that happened, I started doing all types of research to find out why and where my roof was leaking. As I performed my research, I became very interested in the entire industry and even after I hired professional roofers to fix the leak, I still wanted to learn more about roofing. Since I enjoy blogging in my spare time, I decided to start a blog about roofing, and I hope that you also find the information you read interesting and useful.
