How Long Does a Roof Replacement Take?
By Summit Exteriors — Serving East Columbus & Southeast Ohio
If you're planning a roof replacement, one of the first questions on your mind is: how long is this going to take? You want to know how much disruption to expect, whether you need to make special arrangements, and when your home will be fully protected again. The short answer: most residential roof replacements in the East Columbus and Southeast Ohio area take one to three days. Here's the full breakdown.
Roof Size Matters Most
The most significant factor is the size of your roof. A small ranch home with 1,000–1,200 square feet of roof area can often be completed in a single day. A large two-story home with 2,500+ square feet of complex roofline — multiple valleys, hips, dormers — typically takes two to three days. Roofing is measured in "squares" (100 square feet each), and the crew size and schedule are matched to the scope of the job.
Roof Complexity Adds Time
A simple gable roof is significantly faster to replace than a complex hip roof with multiple valleys, dormers, skylights, and penetrations. Every transition point — chimney, skylight, plumbing vent, HVAC penetration — requires careful flashing installation that takes additional time to do correctly. Cutting corners on flashings is one of the most common causes of post-replacement leaks, so we never rush these details.
Tear-Off: How Many Layers?
Ohio's older housing stock often has multiple layers of shingles. Before installing a new roof, any shingle layers beyond the first — Ohio building code allows a maximum of two layers in most municipalities — must be removed. Tear-off typically adds 4–8 hours to a standard home project. We always recommend tearing down to bare decking even when one layer is present: it allows a full inspection of the deck, ensures a flat substrate for new shingles, and results in a significantly longer-lasting installation.
Decking Repairs Are the Wildcard
If we find damaged or rotted roof decking during tear-off, it must be replaced before new shingles can go on. We can estimate the likelihood of deck issues during the initial inspection, but we can't know the full extent until shingles are removed. We always communicate any additional decking needs immediately, before proceeding with repairs, and won't replace more than necessary.
A Typical Two-Day Roof Replacement
For a medium-sized East Columbus home, here's what a typical roof replacement looks like: Day 1 — crew arrives, sets up protection over landscaping and vehicles, performs tear-off, completes a full deck inspection and any repairs, installs ice-and-water shield in valleys and eaves, installs synthetic underlayment across the field, and begins shingling if time permits. Day 2 — completes shingle installation, installs all flashings (step flashing, valley metal, chimney counter-flashing, pipe boots), installs ridge cap and ridge venting, performs final inspection, runs a magnetic sweep for nails, and hauls away all debris. We do not leave a job site until the work is complete and the property is clean.
Weather and Ohio's Unpredictable Skies
We don't install shingles in rain or sustained high winds — both affect adhesion and are unsafe for crew members on a pitched roof. If Ohio weather intervenes mid-project, we secure the roof with tarps and resume when conditions are safe. We monitor forecasts closely and schedule jobs accordingly to minimize weather delays. While this occasionally pushes a completion date back by a day, we never sacrifice installation quality for speed.
Do You Need to Be Home?
You don't need to be home during the work itself, but we recommend being available at the start of Day 1 and at completion for a walkthrough. The work is noisy — hammering, generators, debris falling — so if you work from home or have young children or pets, plan accordingly. Most homeowners find it helpful to move vehicles out of the driveway to give the crew full access.
