How long will asphalt shingles last?

If you replace your roof with an architectural shingle or designer shingle, you will most likely not be replacing the roof on your home again in your lifetime.  25-30 years barring any major weather event is a good expectation.  For a 3 tab shingle, expect the roof to last 15-20 years.

What is the cost of a shingle roof?

The most economical shingle is the 3 tab shingle.  Shingles in general tend to be the most affordable of all roofing choices.  Designer shingles are the most expensive.

What are the Warranties, in general terms?

Most 3-tab shingles have a 25 year warranty and after 7 years, their value starts to pro-rate.  Architectural shingles have a lifetime warranty.  They will start to pro-rate after 10 years but will hold 10-15% of their value of the purchased price after 50 years.  Hence, the lifetime warranty.  So if the shingles fail after 25 years, expect to recover 50% of the cost of the shingles from when they were purchased.  Only the cost of the material is covered.

What is the GAF System Plus or GAF Golden Pledge Warranty?

The GAF System Plus warranty and GAF Golden Pledge warranties are non-prorated warranties that cover 50 years.  This covers only GAF architectural and designer shingles, not the 3 tab shingles.  Even if they fail in year 35, GAF will replace the roof at the current cost of shingles and installation.  This is why when you choose the GAF system warranty, whether it be the System Plus or the Golden Pledge, it will be the last roof you pay for.  Think of it as an insurance policy for your roof.  The best thing is you can transfer it to a new buyer if you decide to sell the house so you get the value from installing a Golden Pledge roof  either way.
