One of the most common questions we hear from Connecticut homeowners is: “How long does a roof replacement take?” The answer might surprise you: most full roof replacements are completed in just one day. At All Site Builders, as a licensed Owens Corning Preferred Contractor, we’ve perfected a streamlined, efficient process that minimizes disruption while maximizing quality. From tear-off to final cleanup, our team works with military precision — so you’re not left with an exposed roof overnight. In this guide, you’ll learn exactly what affects timing, why one day is possible (and safe), and how we ensure every job meets GAF and Owens Corning installation standards — without cutting corners.

To be honest, many people assume a roof replacement takes a week — and with some contractors, it does.
But with a well-trained crew, proper planning, and premium materials, a full roof can be replaced safely and thoroughly in 6–10 hours.
Here’s why:

While most roofs are done in one day, these factors can extend the timeline:
A simple 1,500 sq. ft. ranch? One day.
A 3,000 sq. ft. colonial with multiple valleys, dormers, and skylights? Possibly two days.
But we always provide an accurate estimate before signing.
We never install shingles in rain, high wind, or below 40°F. If rain moves in, we secure the roof with tarps and resume immediately after.
If we find rotted decking during tear-off (common after ice dams), we replace it on-site — which adds a few hours, not days.
Because we’re an Owens Corning Preferred Contractor, we get priority access to Duration Shingles — no waiting weeks for delivery.
Leaving a roof torn off for multiple days isn’t just inconvenient — it’s risky.
That’s why we commit to same-day completion whenever possible. Your home deserves to be fully protected — from sunrise to sunset.
