Properly setting up flashings before nailing down shingles ensures that fail points are covered. Backed by The Bolt Home Flashing System helps contractors meet code and protect key roof components.
PERIMETER EDGE FLASHING
PERIMETER EDGE FLASHING
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 products provide effortless installs and ensure consistent seams and a cleaner look.
ROOF-TO-WALL FLASHING
ROOF-TO-WALL FLASHING
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.
VALLEY FLASHING
VALLEYÂ FLASHING
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
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
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
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.
