From Start to Finish: How Long Does Roof Installation Really Take?

At Mid-Shore Exteriors, one of the most common questions we hear is: “How long does it take to install a roof?” Or more specifically: “How long does it take to put on a roof?” The answer isn’t always simple, because the roof replacement timeline can vary based on various factors, such as the size of your roof, the type of roofing material selected, and the complexity of your roof.
Whether you’re replacing old shingles on a shingle roof installation or upgrading to a premium system like metal roofing, tile roofing, or slate roofs, every roofing project is different. This guide explains what to expect during the roof installation process, what affects your project timeline, and how to prepare your home for a successful outcome.
What Affects How Long a Roof Installation Takes?
1. Size of the Roof / Square Footage
The square footage (or size of your roof) plays a crucial role in determining the roof replacement timeline. Larger roofs—especially those over 3,000 square feet—can take extra time simply due to volume.
2. Roof Design and Roof Complexity
A complex roof with steep roof pitch, multiple valleys, dormers, or skylights will slow things down. The more complicated the roof design, the longer the roofing crew will need to complete the roofing work safely and correctly.
3. Type of Roofing Material
The type of material you choose has a significant impact:
- Asphalt shingles: Usually 1-3 days
- Metal roofing: 3-5 days
- Slate tiles or slate roofing: 6-10 days
- Concrete tiles or tile roofs: 7-10+ days
- Cedar shakes or wooden shingles: 4-6 days
- Flat roof systems: 2-4 days, depending on complexity
Each new roofing material has unique installation requirements that affect the overall timeframe.
4. Weather Conditions and Job Site Accessibility
Weather conditions such as high winds, rain, or extreme heat can delay your roof replacement project. Similarly, easy access to your job site and the condition of your roof decking matter. If there’s water damage underneath the old roofing material, it will need to be addressed first.
5. Crew Size and Experience Level
A large, highly trained roofing team from a professional roofing company like Mid-Shore Exteriors can complete the job faster. The more skilled the roofing professionals, the more efficiently your roofing services are delivered.
6. Roof Accessibility and Safety Equipment
The ease of roof accessibility and necessary safety equipment also influence how quickly work can be performed. Homes with challenging landscaping, fencing, or height restrictions may need extra time to set up properly.
7. Roof Repairs or Storm Damage
If your roof has suffered storm damage or needs structural roof repairs, your project timeline will be longer. Addressing rotted decking, replacing flashing, or fixing damaged underlayment adds time but is critical to a long-lasting roofing system.

What Happens During the Roof Replacement Process?
Understanding the roof replacement process helps homeowners feel more prepared. Here’s what our roofing professionals typically do.
1. Inspection and Tear-Off
We begin by inspecting the existing roof decking for water damage or rot. Then, the old shingles or other old roofing material are carefully removed. This step is crucial for revealing hidden issues.
2. Deck Prep and Drip Edge Installation
We prep the roof deck with underlayment and install drip edge flashing around the perimeter to help prevent moisture intrusion.
3. Installation of New Roofing Material
Your selected type of roofing material—be it metal roofing, tile roofing, cedar shakes, or slate roofs—is then installed by our skilled roofing crew.
4. Sealing and Ventilation
Proper sealing and ventilation ensure energy efficiency and longevity of your roofing system.
5. Final Inspection and Cleanup
No one likes a messy job site. Our team conducts a thorough inspection and leaves your property cleaner than we found it.
Tips to Prepare for Your Roof Replacement
- Plan Around the Weather: Work with your contractor to schedule during favorable weather conditions.
- Clear Your Driveway and Yard: This gives the roofing team better access and helps them work more efficiently.
- Protect Your Belongings: Cover attic storage and remove fragile items from walls and shelves.
