Question 1

Is my roof ready for solar panels?

Accepted Answer

Your roof is likely ready for solar if it: (1) has a south, southwest, or west-facing slope, (2) has less than 20% shading during peak sun hours, (3) has at least 10-15 years of remaining life, and (4) is made of asphalt shingle, metal, or tile.

Question 2

How old can my roof be before installing solar?

Accepted Answer

Solar panels last 25-30 years. If your roof is more than 15 years old and made of asphalt shingles, consider replacing the roof before installing solar to avoid paying for panel removal and reinstallation mid-system-life.

Question 3

What roof type is best for solar panels?

Accepted Answer

Asphalt shingle roofs are the easiest and most economical to install solar on. Metal standing seam roofs are ideal because clamps attach directly to seams without penetrations.
