3 Tips for Metal Roofing Installation Over Shingles

1. Count the Layers

If you plan to install your new metal roofing over asphalt shingles, you should first determine how many layers of roofing exist. If there are two or more, it may not be legally permitted to perform the installation. Your local ordinance offers up-to-date codes and can provide you with the appropriate information.

2. Check the Condition

Once you determine if it’s appropriate to install over existing asphalt shingles, you should then check the condition of your current roofing. The layer must be in good condition because if it’s not structurally sound, then it could affect the integrity of the metal. Look for signs of deterioration or weakness, such as rot, flaking, or peeling.

3. Examine the Rooftop

Other elements on your rooftop may be affected if you install metal over your asphalt shingles. If you have a rooftop HVAC system or a skylight, for example, their functionality may suffer. A vital component of the HVAC unit could be blocked, or a shadow could inhibit ample light from filtering through a skylight.

Keeping these essential tips in mind will be helpful as you begin the process of installing a metal roof and improving the strength and integrity of your home. For tools, materials, and advice, call the specialists at Dixieland Metals of Alabama at (334) 678-0038, or visit their website.
