Roofing and Siding Guide

Roofing materials range from economical 3-tab shingles to premium architectural shingles that offer better durability and curb appeal. Siding choices include vinyl (low maintenance), fiber cement (fire resistant and long lasting), and wood (natural appearance). Your choice depends on climate, budget, and desired maintenance level. Use our calculators to estimate roofing squares, shingle bundles, and siding pieces for your exterior project.

Installation Tips

Always install drip edge and underlayment before shingles
Use the right nail length for your shingle type
Allow siding to acclimate for 48 hours before installation
Leave expansion gaps in siding for temperature changes
