As you plan your metal roof replacement, you might wonder whether you should have your old shingles removed first before having a new one installed. If you consult with us at Tony’s Roof Care, our answer depends on what kind of roofing you currently have installed. In most cases, however, we install metal roofs over existing asphalt shingles. In our experience, it’s normal practice to do so.

It Doesn’t Affect the Overall Weight of Your Roof

Since steel shingles typically weigh about 1/4 of what asphalt shingles weigh, and aluminum shingles weigh about 1/8 of what standard shingles weigh, it will hardly make an impact on your roof’s overall weight. In fact, less weight is actually being added to your home by the new metal roof than what your current shingles have, especially if they’re old due to granule wear and oil evaporation.

Installing New Shingles Over Old Ones Isn’t Recommended

The word “Lifetime” refers to the length of coverage provided by your GAF warranty. This means as long as you, the original owner(s) (or the second owner(s) if coverage was properly transferred during the Smart Choice® Protection Period) own the property where the shingles and/or accessories are installed, your Lifetime Limited Warranty is covered by our roofing company. Keep in mind that this type of warranty is only applicable to shingles and accessories installed on a single-family detached residence owned by individuals.

Why Metal Is More Reliable

Metal roofing and its paint finish won’t get damaged even under extreme temperatures. And, unlike asphalt shingles, the warranty we offer on your new metal roof won’t be affected even after it’s installed over your old shingles. This is because it never really becomes an issue, even if it’s installed over old wood shingles or even thinner wood shakes.
