Should I re-shingle over my existing shingle roof?
Adding a new layer of shingles over your already existing shingles can in fact be done, but a roof that is re-shingled is not nearly as strong as a roof that is completely torn off and re-roofed.
Can I vs. Should I
While the ultimate answer here is, yes, this can be done, there are some stipulations your roof must meet to move forward this way, because proceeding this way solely depends on the condition of the current roof. If the shingles are in good condition and your home is structurally sound to stand up to the weight of another layer of shingles, then this may be a cost effective way to extend the lifespan of your current roof; However, it must be stressed that even if the shingles appear to be good, it is still suggested that you start from scratch.
Benefits of a Fresh Start
It is suggested to tear off & re-roof is because it allows the roofer to see the underlayment and the condition of the sheathing. A roof is only as strong as the foundation it lays upon, and if the sheathing is wet and rotting, adding more weight with another layer of shingles could in fact put your home in a precarious situation making it subject to collapse. Since it cannot be known if dry-rot is occurring until the old roof comes off, it is wise to start fresh.
By tearing off the old roof, dry-rot will be located and replaced, new underlayment and shingles will be installed, leaving you with a strong, water-tight roof you won't have to stress about it for another 20 years.
