How long do asphalt shingles last?
Asphalt shingle roofs commonly last around 20 to 30 years, depending on the shingle type, installation quality, ventilation, and local weather. Architectural shingles generally last longer than three-tab shingles.
What is the difference between three-tab and architectural shingles?
Three-tab shingles are flat, basic, and cheaper, with a shorter lifespan. Architectural shingles are thicker, layered, and more durable, with a textured look. They cost more but generally last longer and resist wind better.
Can a shingle roof be repaired, or does it need replacing?
A few damaged shingles on a young roof can be repaired. Widespread curling, cracking, granule loss, or repeated leaks point to replacement. A professional inspection helps you decide.
Will new shingles match my existing roof?
A contractor will try to match the existing shingles, but an exact colour match is not always possible on an older roof, where the existing shingles have faded. Ask about this before the work starts.
How much does a shingle roof cost?
It depends on roof size, pitch, complexity, shingle type, tear-off, decking condition, and local provider availability. There is no fixed price. An inspection and a written estimate from a qualified contractor is the only reliable way to know.
Is a shingle roof or a metal roof better?
It depends on your priorities. Shingles cost less upfront, are easier to repair, and are more widely available. Metal roofing costs more upfront but generally lasts longer and needs less maintenance. Our metal roofing page explains the comparison in detail.
