The Book On Roofing

Material Options

We believe in providing the homeowner with plenty of options to choose from when it comes to the materials going up on the roof. We believe in GAF products and recommend their use, however, if the homeowner believes in a different product but also believes that The Exterior Company is the best choice of roofing contractor, then we will install that product and it will come with our 10 year workmanship warranty plus the standard material warranty for that product. Our standard repertoire includes the GAF Timberline HD lifetime architectural shingles, GAF Seal a Ridge ridge cap, GAF Pro-Start Starter strip, GAF Shingle Mate 30lb underlayment, GAF Weatherstopper Ice and Water Shield, and the GAF Cobra Exhaust/Ridge ventilation, with Alcoa drip edge around your perimeters. Upgrades include GAF synthetic Deck Armor underlayment, Grace ice and water shield, GAF Weatherblocker starter strip, GAF Snow Country Ridge vent, and the GAF Ultra HD Timberline Shingle with GAF Timbertex ridge cap, (or any of GAF’s designer series shingles, which are rated for 50 years, plus have intricate designs that can add aesthetic appeal to your home).

Think of this as a good-better-best. No matter what roofing components we install – it will be good – a job well done – a roof that will last the full service life. We like to equip you with “better” right off the bat; our standard repertoire is better than what many companies use. If you want the very best that money can buy, we can provide you with this, at a price that will beat the (few) other companies who can provide you with a comparable roofing system.
