Preparing/Protecting The Job Area
Some general suggestions for preparing the job area:
- Make sure you have a clean and organized work area
- Block the work area off from children and pets
- Identify and avoid all site danger areas such as dangerous power lines, unsafe roof access areas, and underground hazards (such as cesspools and power lines)
- Remove wall hangings as well as any loose items from walls and shelves
- Use tarps to avoid damaging plants and shrubs – Create a debris removal plan
- Park all vehicles away from the driveway and a safe distance from the construction area
- Cover items in your attic and garage to protect from tear off dust and debris
- Disable any sprinkler systems
- Cover any pools and hot tubs, and remove any other sensitive items around the house that might be damaged by falling roofing
Tearing Off The Roof And Preparing The Roof Deck
Nothing is more important in roofing than preparing the surface under the shingles. With a roof tear-off, when the old materials are removed, you’ll have a clean deck that allows you to see any potential problems that need to be fixed. This could range from rotten wood to cracked boards to an unsound deck that won’t hold nails as well.
For the proper methods for tearing off a roof and preparing the roof deck, see our How-To-Video.
Installing Roof Deck Protection
The proper installation of high-quality roof deck protection like Deck-Armor™ Premium Breathable Roof Deck Protection, Shingle-Mate® Roof Deck Protection, or Tiger Paw™ Roof Deck Protection is the foundation on which a good roof system is built.

Installing Leak Barrier
Protect your investment and safeguard vulnerable areas of your roof with proven leak barriers from GAF.
Starter Strip Shingles
One of the most common sources of failure in a roof system is the improper installation of starter shingles. This starter course is very important – especially for wind resistance. Starter strip shingles are the first line of defense against wind uplift along the edges of a roof. GAF offers pre-cut WeatherBlocker™ Premium Eave/Rake Starter Strip Shingles and Pro-Start® Starter Strip Shingles.
Proper Shingle Nailing
Nailing errors, such as under-driven or angled nails, can cause future problems with your shingles—everything from premature failure to blow-offs. Nail type, location, length, angle, and impact force used to drive the nail are all critical to consider when installing shingles. It’s important to take your time when nailing down your shingles to ensure the job is done correctly.
For the proper shingle nailing technique, see our How-To Video.

How To Install Valleys
Valleys are one of the areas of roofing that takes careful planning and time to install correctly. Valleys are a prime leak area, so it’s important to be precise during installation. Make sure to utilize a leak barrier in the valley.
See our How-to Video for installing valleys.
Wherever surfaces intersect on a roof, there is a chance of water seepage. Flashing is required for waterproofing these critical areas of your roof. At walls, step flashing is a proven way to protect your property.
See our How-to Video for installing flashing and details.
Installing Ridge Vents
Proper ventilation is critical for helping to reduce hot and moist air in your attic space that can damage your possessions, result in mold growth, increase your energy costs, and potentially reduce the longevity of your roofing system. The Federal Housing Authority in the U.S., the Engineered Wood Association, many national building codes, and all major roofing manufacturers have requirements for the installation of attic ventilation. GAF offers one of the industry’s most comprehensive line of ridge vents.
Installing ridge vents requires working on some of the highest parts of your roof—the ridges. As always when working on a roof, utilize proper safety equipment to prevent falls or injury when installing ridge vents on your roof. See our Safety section for more details.
Deciding on the proper vent and the amount of ventilation needed is critical. Consult your local building code for balanced attic ventilation requirements in your area. Once you decide on the type of vent that is needed and how much to install, always ensure you install the vent as per written application instructions. Be careful not to cut any attic rafters or wires, and always ensure to properly fasten the vent to prevent blow-off or weather infiltration.
See our How-to Video for installing ridge vents.

Installing hip or ridge shingles requires working on some of the highest parts of your roof—the hips and ridges. As always when working on a roof, utilize proper safety equipment to prevent falls or injury when installing hip or ridge shingles on your roof.
