The Most Important Day for a Roof is Installation Day
Getting your flashings set up correctly before your shingle is nailed down insures that the failpoints are covered. Failpoints are typically found anywhere your shingle does not lay flat on the roof, the shingle ends, or anywhere there is a protrusion in the roof.
The Backed by the Bolt Home Flashing System is set up to make sure contractors meet code when installing key components of your roof.
CODE SUMMARY
Drip edges must be installed at eaves and rake edges of shingle roofs, overlapping adjacent segments by at least 2 inches. They should extend 1/4 inch below the roof sheathing and 2 inches onto the roof deck, fastened at intervals not exceeding 12 inches. Underlayment should be placed over the drip edge at eaves and under it at rake edges.

PREVENTS WOOD ROT
Water that is not channeled away from the home causes structural damage to the home.
PREVENTS BUG INFESTATION
Cover the gap to make sure bugs and critters are not finding their way into the home.
PREVENTS FLARE-OUT
Infinity and TruFit Drip Edge offer easy installs, consistent seams, and a cleaner finish.
CODE SUMMARY
Flashings must be installed as per the shingle manufacturer's instructions. Base flashings should use corrosion-resistant metal (minimum 0.019 inches thick) or mineral surface roll roofing (minimum 77 lbs/100 sq. ft.). Cap flashings must be made of corrosion-resistant metal with a minimum thickness of 0.019 inches.

PROTECTS THE SIDEWALL
Water that gets behind the siding will rot out the walls and create leaks into the home.
PROTECTS THE ROOF DECK
Water that makes its way under the shingles will rot out the shingles and void any warranty in place.
PROMOTES AIRFLOW WITH
BEADED WATER LOCKS
Creates airflow moving water away from the roof and away from the home.
CODE SUMMARY
Valley linings must be installed according to the manufacturer's instructions. For open valleys with exposed metal lining, the lining should be at least 24 inches (610 mm) wide and made of a corrosion-resistant material.

PROTECTS AGAINST GRANULE LOSS
Helps to prevent granule loss by directing water runoff away from roof seams, reducing erosion in vulnerable areas.
PROTECTS AGAINST DEBRIS BUILD-UP
Channels water away from roof valleys to minimize debris buildup that can cause blockages and long-term damage.
PROTECTS AGAINST ICE DAMMING
Ensures proper water flow, reducing the chances of water freezing and backing up under the roof.
UNDERLAYMENT
CODE SUMMARY
Underlayment should be installed per the manufacturer's instructions, starting horizontally at the eave with at least 2-inch overlaps for successive sheets and 4-inch overlaps at end laps.

LEAK BARRIER
A self-sticking membrane that helps protect against leaks caused by wind-driven rain and damaging ice dams.
SYNTHETIC OR FELT UNDERLAYMENT
An underlayment that provides a secondary layer of wind-driven rain protection between the shingles and roof deck.
SHINGLE STARTER
A starter layer of shingles that provide a sealant to the first row of shingles preventing blow offs and wind-driven rain.
VENTILATION
CODE SUMMARY
Typical one-foot soffit overhangs should have at least an 11 NFA, so when used on both sides of the home, they will have a combined NFA of 22 to draw the airflow needed to work with a ridge vent system.

PROPER AIR FLOW
Sufficient airflow reduces the strain on heating and cooling systems to maintain consistent indoor temperatures.
INADEQUATE AIR FLOW
Without proper ventilation, a roof becomes vulnerable to mold, structural damage, and compromised insulation integrity.

GUTTER PROTECTION
BEST PRACTICES
QE TruGuard® Gutter Protection helps prevent water issues by keeping gutters free of debris. It attaches to the fascia using patented fasteners and features a unique nose-forward design that allows only water to enter, keeping out leaves and debris for a free-flowing gutter system.
PROTECTS AGAINST
CLOGGED GUTTERS
Gutter Protection helps keep debris like leaves, twigs, and other small objects from entering the gutter and clogging it.
PROTECTS AGAINST
FOUNDATION DAMAGE
No more clogged gutters means no water overflowing and potentially damaging the foundation of the home.
PROTECTS AGAINST
STANDING WATER
No more clogged gutters also means no insects and mold growing in the gutters.
SHINGLE MATCH
Color Match System
The Bolt™ Home Flashing System offers matching options for both shingle and siding lines, ensuring you find the perfect fit for your project.
