GAF shingles vs Tamko shingles

Asphalt shingles are the most common roofing material in this country today. Since a roof is a big investment, you want to make sure you’ve chosen an option that lasts… and make sure it comes with a good warranty.

The popularity of architectural shingles with long warranty periods of 20, 30, 50 years and even lifetimes is announced today. However, if you don’t read the fine print, you might be very surprised at what is actually covered and the amount of collateral you really get. Here, we are going to make a comparison between two shingle companies; GAF and TAMKO.

GAF

GAF is popular for producing economical roof shingles that come in different varieties of colors. GAF is renowned for offering the best price options, aesthetic shingles and the architectural style of the home.

Warranty

GAF shingles warranty is elaborated as follows;

  • Material defects are covered for 3 years on 25-year-old 3-tab shingles and for 5 years on 30-year 3-tab shingles
  • The GAF guarantee is not prorated for the first 10 years. The amount of cover decreases each year until year 40 when it is 20% for the rest of the guarantee.
  • To fully benefit from the GAF Lifetime Limited Warranty, you must install two other “eligible GAF accessories” such as the GAF Cobra attic ventilation, the GAF Deck Armor roof deck underlay, the GAF starter strip shingles and GAF ridge shingles.
  • The GAF StainGuard warranty covers shingles against stains for 10 years in temperate zones and 5 years in tropical zones.

GAF has been known to possess the most ideal warranty package in the roofing business. When a roofer certified “Master Elite” by GAF installs shingles, better guarantees are offered.
