There are two components to buying a new roof:

• The Manufacturer.
• The Installer.

The Manufacturer provides the shingle warranty.

• 30year, 40 year, Lifetime (50 year).
• This warranty only covers defects in the material.
• These warranties are prorated over the lifetime of the warranty.
• These warranties typically don’t cover workmanship or roof leaks

The Installer provides the workmanship warranty.

• This warranty should provide that the shingles will be installed in compliance with the Manufacturer’s specifications.
• This warranty should provide that the shingles are installed to industry standards and in a manner that the roof will not leak.
• Typically, the longer the workmanship warranty the better the roof job.

If the Installer fails at the roof installation, the manufacturing warranty is in jeopardy.

CONCLUSION: Emphasis should be placed on hiring a reputable installer with good references and tenure.

Gold Country Roofing has been serving Penn Valley, Nevada City, Grass Valley, Lake Wildwood, Lake of the Pines, and Colfax for 29 years. We offer a TEN YEAR workmanship warranty

• 30 year roof will cost about $.065 cents, per square foot per year, if the roof is overlaid and about $.09 cents, per square foot per year, if the roof is torn off.
• A 40 year roof will add ten years to the roof life, at a cost of  $.025 cents per square foot per year. If you adjust for the time value of money with a two percent difference between investment and inflation your 40 year roof will cost $.045 per square foot per year.

So the only reason not to buy a 40 year roof is because you are going to die soon or you just don’t have the money! There are other legitimate reasons not spend money on your roof, however the economics of a 40 year roof are sound.
