Reroofing vs. Roof Replacement: What’s the Difference?
The terms reroofing and roof replacement (or installation) are often confused, but they represent two distinct methods of restoring your roof. The right choice for your home depends heavily on the current condition of your roof and local building codes.
Feature Reroofing (Roof Overlay) Roof Replacement (Full Tear-Off)
Process
Involves layering new shingles directly over the existing layer of shingles. Involves removing all existing roofing materials down to the roof deck (sheathing) and installing a completely new system.
Cost
Generally less expensive due to lower labor and material disposal costs. More expensive due to the cost of tear-off labor, disposal, and potential deck repairs.
Duration
Faster, often taking only 1-2 days. Takes longer, typically 3-7 days or more.
Underlying Issues
Cannot address or inspect the underlying roof deck for rot, water damage, or structural issues. Allows for a complete inspection and repair of the roof deck and structure.
Code Limits
Typically only permitted if the roof has one existing layer of shingles (local codes prohibit a third layer). Always permitted, as it creates a brand-new, single-layer system.
Lifespan
Provides a shorter lifespan extension (often 10–15 years) compared to replacement. Provides the maximum lifespan and long-term durability for new materials.
When is Reroofing an option?
Reroofing is a viable, cost-effective, and fast solution if your roof has only one existing layer of shingles, is structurally sound (no sagging or major water damage), and you are primarily looking for a quick visual refresh and moderate lifespan extension.
Signs Your Roof May Need Reroofing or Replacement
Identifying early signs of roof distress can save you significant time and money by preventing major water damage. If your roof is approximately 15-20 years old and shows minor to moderate signs of wear, a reroofing might be an appropriate and budget-friendly option.
If you observe any of the following signs, it's time to call Siar Construction for a free, professional roof inspection:
Curling, Cupping, or Buckled Shingles
Shingles that aren't lying flat against the roof surface are vulnerable to wind and water damage.
Missing or Damaged Shingles/Tiles
Patches where the protective layer has been stripped, or individual shingles are cracked or missing.
Granules in Gutters
Asphalt shingles lose their protective mineral granules over time. Finding a large accumulation of these sand-like particles in your gutters or downspouts indicates that the shingles are nearing the end of their useful life.
Roof Age
Most asphalt shingle roofs are designed to last around 20-25 years. If your roof is approaching this age, even without visible major damage, its protective capabilities are diminishing.
Widespread Moss or Algae Growth
While minor cleaning can sometimes help, extensive growth can trap moisture against the roof surface and accelerate deterioration.
If you notice any signs of a structural issue like a noticeable sag in the roofline, dark water stains on your interior ceilings, or active leaks, you likely require a full roof replacement to address the underlying damage to the roof deck and structure.
