Metal Roofing: Metals

Steel is the workhorse, aluminum shrugs off salt air, copper and zinc last a century and change color as they age, and stainless handles the harshest coastal and industrial sites. These guides compare the metals on life span, weight, cost, coatings, corrosion, where each one belongs and where it does not, so you can read a bid and know what you are paying for.

Buying GuideThe decisions inside a metal roofing bid: gauge and thickness, PVDF versus SMP paint systems, underlayment and ventilation, metal over existing shingles, the four kinds of warranty and what they exclude, and a step-by-step method for choosing a contractor you can trust. Read these before you sign anything.6 guidesCare & MaintenanceA metal roof asks for little, but not nothing. These guides cover the yearly walk-around from the ground, gutters and snow retention, fastener checks on exposed-fastener roofs, sealant life, touch-up paint, what to do after hail, and when to call the installer instead of a handyman.2 guidesCost & ValueWhat a metal roof costs installed in 2026, style by style and state by state, how that compares with asphalt shingles over the life of the roof, what moves a bid up or down, and the value side: insurance discounts for Class 4 impact ratings, energy savings, and what metal does for resale. Pair these with the cost calculator before you request quotes.3 guidesDesignThe choices you look at every day: color and finish, how a roof color works with siding and trim, which colors hold up in sun, and how solar panels mount to a metal roof without a single penetration. Practical design help for homeowners and the architects and builders they work with.2 guidesMetalsSteel is the workhorse, aluminum shrugs off salt air, copper and zinc last a century and change color as they age, and stainless handles the harshest coastal and industrial sites.

Each guide explains how the system goes together, which roofs and climates it suits, roughly what it costs installed, and the questions that separate a good bid from a cheap one.9 guidesWeather & PerformanceHow metal roofs handle what the sky throws at them: hail and the UL 2218 Class 4 rating, hurricane and straight-line wind, wildfire and ember attack, summer heat and cool-roof reflectivity, and the two myths that will not die, noise and lightning. Each guide separates what the test standards actually say from what a sales pitch implies.5 guides
