The Roofing Process – Installation

Step 1. We start by removing your old roof down to the plywood. This is done to reveal any hidden damage and also so the new roofing materials can be installed in the approved manner. We do not go over the existing shingles because manufacturers will not warranty your new roof properly since it is likely the new shingles will suffer the same issues in a matter of no time.

Step 2. Once the shingles are completely removed we do a full deck inspection. This is done to ensure we are not covering up problems when the new roof is installed. If there are areas of bad wood or an uneven deck, (as in the example at right) we will replace them with new sheets of plywood or OSB. Installing on an uneven deck will cause premature wear, and the roof will appear lumpy and unattractive. It is far less costly to tackle the problem while your roof is open.

 

Step 3. This starts the installation process. To the right you will see a thin strip of metal referred to as the 1 1/2″ drip edge. We always replace all of the old drip edge, It is a simple way to compliment your trim color and give your home a clean and polished finished look. We match all drip edge to the color of your existing trim metal to make your trim appear larger and more attractive.

Next is easily the most overlooked portion of the roofing process, The Starter Strip. We Always use GAF Pro Start on the eaves AND Rakes, typically they are used only on the eaves. We use them on the rakes to prevent against wind driven rain, and to create a nice finished and sealed edge. GAF Pro Start has a continuous sealant protecting all roof edges around your home.

In addition to using starter strips on the rakes we install all shingles using 6 nails instead of the standard 4 nail process. This upgrades you to the maximum wind warranty protection at 130mph.
 

Step 4. This begins with Installing GAF Weather Watch Ice and Water Shield in key locations. Minimum code is 24″ into the “warm walls of the house” or roughly 36″ on all eave edges. However as 36″ barely meets code it is our practice to go a full 72″ on the eave edges.

Although not a code requirement, in addition to the eave edge protection we install 36″ in the valleys, around dormers, chimneys, skylights, roof transitions (where a low slope meets a higher one). We also replace any old pipe boot flashings (typically where a plumbing pipe protrudes through the roof).

Ice and water shield offers great protection, however, it is not wise to cover your entire roof with it unless required by code for low slope installs (under 4/12 pitch.) Your roof needs to breathe to allow the natural vapors from your house to escape.

  
Step 5. On the remainder of the roof area we install a synthetic underlayment called GAF Tiger Paw. This is a unique product that acts as a backup weatherproofing source in case of shingle blow off or damage from debris occurs. Most people do not (or cannot) look at their roof on a daily basis so what’s under your shingles is extremely important if a shingle becomes damaged.

Tiger Paw can be exposed up to 6 months and remain virtually waterproof, whereas standard OR fiberglass reinforced felt offers little to no exposure time before it is critically prone to leaking. 15#/30#/fiberglass felt are con- sidered base products and serve only as a minimum code fulfillment item and offer no real protection. Other generic
synthetics are available but they are non-breathable and cannot dissipate moisture potentially causing adverse long term affects to your roof deck. We also offer GAF Deck Armor. If your home has limited ventilation options, Deck Armor is the only real choice.

Step 6 We have 3 choices for GAF shingle types: 3 tab, Architectural, and Designer. 3-tab’s are basically obsolete so unless you absolutely can’t live without them they are not ad- vised, not to mention they carry a 25-year warranty.

Architectural is the most popular and are designed to mimic the look of wood shake shingles. They give a nice appearance upgrade over 3 tab shingles and a huge upgrade to durability thanks to it’s 2 part laminated design. All GAF architectural shingles are lifetime warranty.

The designer class shingles are a relatively new breed of Designer-Country Mansion shingles and were created to give your home a sophisticated and unique look. They are all lifetime products and no matter what your style may be, there is a design that is sure to give your house the edge it deserves. For full product offerings, please see our upgrades and options page.

  
Step 7 The last step in the new roof process is the installation of the ridge vent and ridge cap shingles. If your home cannot support a ridge vent system then you will have traditional “can vents” or power vents installed, whichever system is optimal for your situation.

We install GAF Snow Country Ridge Vent System because it is the highest venting ridge vent product on the market. Roll out venting systems are quick and easy to install and cost less but do not offer the same advantage of a rigid vent system

For the ridge cap we use GAF Seal-A-Ridge, not a generic 3 tab. When a 3 tab shingle is used there is no warranty since you are using it in a manner that it is not designed for. Another option is GAF TimberTex which is an inexpensive upgrade and makes a real nice impact on the appearance of your roof.
