Tile and shingle roofs both have their pros and cons. In general, tile roofs are a larger upfront investment. In some cases, they can cost twice as much as shingles, but they last much longer and generally hold their value better than shingle roofs. Shingle roofs, on the other hand, are budget-friendly and quicker to install.
