The short answer is, yes, cedar shakes do last longer than asphalt shingles. But the long answer is, it depends on maintenance. Asphalt shingles last about 20 years, while cedar shingles typically last about 30 years with proper maintenance. If they are very well maintained and installed in an area with a mild, drier climate, they can last up to 50 years.

Furring strips (also called wood stripping) are not always necessary for a metal roof installation, but they are highly recommended and may be required by local building codes or the roofing manufacturer's specifications. There are several key reasons to use them:

• Energy Efficiency: Furring strips, made of wood or metal, create an air gap between the metal panels and the roof deck. This acts as a thermal break, reducing heat transfer into your home and improving overall energy efficiency.

• Moisture and Condensation Control: The air gap allows for better airflow, which helps prevent moisture buildup and condensation under the metal panels.

• Structural Support: They provide a solid, even frame to which you can attach the metal roofing panels.

It is especially important to use furring strips when installing a metal roof over existing shingles. Without them, the roof surface can be uneven, and you will experience greater solar heat gain.

Roofing replacements and repairs expose the interior of your home to the elements. Failing to protect these areas during inclement weather can cause extensive damage and job delays. Have a conversation with your pro to learn their plans to use tarps, plastic sheeting, or other waterproofing methods to keep your home safe. Also, ask whether your pro will inspect your home during rain or snow to ensure the covering works.

Whether a metal or shingle roof is better for you depends on your preferences. Standing seam metal roofs require little to no maintenance, but if you install a screw-down metal roof where the fasteners are exposed, the gaskets on the fasteners will dry rot and need to be replaced. Generally, screw-down metal roofs need to be re-screwed every 15 to 20 years.

Metal roofs are energy-efficient and have extended warranties, while asphalt shingles are less durable than most. They tend to lose color and get damaged over time, and absorb heat from the sun.
