Protection. Explained in full.

Roof decking

Every protective layer starts with a sound roof deck. The wood panels support the covering and give roofing fasteners material to hold.

Inspect the exposed deck before covering it. Damaged panels need repair or replacement. Panel thickness, framing and span rating determine edge support: H-clips, blocking or tongue-and-groove edges may be specified. Clips are shown as one example.

1. Beneath the finish. The wood deck stays attached to the structure beneath the protective roofing layers.
2. Check the foundation. Panel edges, supports and surface condition matter before new roofing goes on.
3. A secure connection. Roofing fasteners need suitable decking below the layers they hold.
4. The correct layer order. Underlayment belongs above the deck, with the starter and field shingles above it.

Recorded guide: Let's look underneath. A sound deck supports every layer. Damaged panels need repair before the new roof covers them.

Georgia-Pacific roof sheathing

Drip edge

This thin folded metal directs runoff away from the fascia and toward the gutter. Its projecting edge keeps the drainage path clear at the roof perimeter.

In this detail, eave metal goes beneath the synthetic underlayment; rake metal goes over it. The gutter sits separately below the roof edge.

1. A thin metal profile. The roof flange lies flat, while the small projecting drip clears the fascia.
2. Eave metal comes first. At the eave, metal attachment precedes the underlayment that covers its roof flange.
3. A downhill lap. The synthetic layer overlaps the eave metal so water can continue downhill.
4. A separate gutter below. The projecting drip directs runoff toward the collecting gutter below it.

Recorded guide: That thin metal edge has an important job. It guides water clear of the fascia and toward the gutter below.

GAF Deck-Armor edge details

Ice and water shield

A self-adhered membrane adds protection at vulnerable roof details. This North Texas example focuses on valleys, penetrations and wall transitions, without a continuous perimeter band.

Remove the release film and bond the membrane to its prepared substrate without wrinkles. Its position relative to field underlayment follows the specific valley, pipe or wall detail.

1. Concealed protection. The membrane belongs beneath the completed covering at vulnerable roof details.
2. A bonded membrane. Installation requires removal of the release film and firm adhesion to the prepared substrate.
3. Detail-specific connections. Successive pieces and adjoining layers need laps that shed water, with the exact order determined by the detail.
4. Protection beneath the finish. The finished covering conceals this backup layer; membrane is not an exposed patch over completed shingles.

Self-adhered membrane protects vulnerable details beneath the finished covering. It bonds to the prepared substrate after its release film is removed.

Water from two slopes meets here. A continuous, correctly lapped valley membrane provides backup beneath the finished valley covering.

Pipe and wall details need specific membrane laps and flashing. The selected pipe patch goes over field underlayment and remains below the finished covering.

Valleys, pipes and wall transitions need their own correctly lapped protection. Peaked checks these details as part of the complete roof system.

Recorded guide: Here is the backup beneath the finish. A bonded membrane protects vulnerable details, including valleys and carefully flashed openings.

GAF StormGuard installation

Synthetic underlayment

The broad synthetic sheet sits above the deck and beneath the starter and shingles. Its overlapping courses create another downhill path for water beneath the finish.

Use the selected underlayment’s sheet exposure, course and end laps, and specified cap-fastening pattern. Product, roof slope and wind conditions determine the final detail; the animation illustrates the order of work.

1. Begin at the eave. Horizontal courses start at the low roof edge, over the eave metal. Upper courses lap over lower ones, giving water a continuous path down the roof.
2. Unroll across the slope. The roll travels sideways, keeping the sheet flat across the roof.
3. Capped attachment. The selected underlayment requires broad cap fasteners at its specified attachment locations.
4. Successive courses above. Upper courses overlap from above. Starter strips and field shingles are installed after this layer.

Recorded guide: The sheet runs along the eave, then higher courses overlap it. The selected product sets the laps and cap-fastener pattern.

GAF Deck-Armor standard installation

Starter courses

Starter strips complete the roof edge beneath the first field course and provide the specified sealant connection. The starter assembly must match the selected field shingles.

Install the starter assembly after the synthetic underlayment. Its overhang, joints, fastening and sealant placement follow the selected products. Some systems require an additional starter course.

1. Underlayment comes first. The synthetic sheet belongs below the starter assembly.
2. A prepared roof edge. The starter follows the edge with the overhang and sealant position specified for the product.
3. Match the shingle system. Use the compatible starter and its prescribed attachment. Certain systems need an additional starter course.
4. Beneath the field shingles. The first field-shingle course sits above the completed starter assembly.

Recorded guide: The starter goes above the underlayment and below the first shingle course, with the edge seal and fastening specified for that system.

Manufacturer starter-system example

Shingles and fastening

Individual shingles are laid in overlapping courses, fastened, then covered by the next course. The selected shingle determines the exposure, stepped course starts, nail count and fastening zone.

Seat each roofing nail square and flush within the product’s prescribed fastening zone. Five fasteners illustrate the action here; the actual count, positions and course offsets must follow the current product instructions and applicable wind detail.

1. Place one shingle at a time. Each unit is positioned before it is fastened. The five fastening actions shown are illustrative; the selected product governs the actual pattern.
2. Contact. Drive. Move.. The roofing nailer contacts the fastening zone squarely, drives the nail, then moves to the next position.
3. Work upward in stepped courses. Each new course overlaps the one below. Whole-shingle end joints follow the manufacturer’s specified offsets.
4. Conceal the attachment. Upper courses cover the prescribed fastening areas. Heads must sit flush without cutting the shingle or standing proud.

Recorded guide: Watch the next shingle settle into place. A coil nailer seats the heads flush in the prescribed zone. The next course covers them.

Manufacturer fastening-pattern example; requirements vary

Roof valleys

A valley collects runoff from both adjoining slopes. In a closed-cut valley, shingles from one plane extend across the valley beneath the trimmed courses of the adjoining plane.

The concealed membrane protects the valley below the shingle assembly. Follow the selected shingle’s permitted valley method, crossing courses, cutline, edge treatment and fastener-free center zone.

1. Two roof planes meet. This intersection carries the combined runoff from the adjoining slopes.
2. A concealed membrane. Self-adhered protection remains beneath the finished valley covering.
3. Overlapping shingle planes. The closed-cut detail depends on one plane extending beneath the cut edge of the other; a center seam alone does not complete it.
4. A clear drainage route. The prescribed cutline and fastening locations help preserve a downhill path through the valley.

Recorded guide: Watch one plane's shingles cross the valley. The adjoining courses cover them, leaving a trimmed drainage edge above the concealed membrane.

Manufacturer closed-cut valley example

Pipe flashing

Peaked uses metal 3-in-1 pipe flashing: a formed metal base with a fitted sealing collar. Its lapped flanges move water around the opening and back onto the shingles.

In the illustrated GAF pipe detail, the membrane patch goes over field underlayment. Install lower shingles, then the boot; upper courses cover the uphill flange while the lower apron drains over shingles.

1. A local protection detail. The pipe opening connects to field underlayment, a membrane patch and fitted flashing.
2. A fitted collar. The collar fits the pipe while the lower flange rests over the downslope shingles.
3. The uphill flange is covered. Upper shingle courses overlap the uphill flashing, completing its connection to the roof.
4. The apron drains above shingles. The lower apron directs water onto the roof below, rather than behind the covering.

Recorded guide: Water needs to move around the pipe. Upper shingles cover the flashing flange, while the lower apron drains onto the course below.

GAF pipe flashing detail

Chimneys and step flashing

A chimney interrupts the water path. Individual step flashings interleave with courses at its sloping sides, a downhill apron drains onto shingles, and counterflashing protects the wall connection.

Interleave a separate step with each shingle course at the sidewall, protecting the wall leg with correctly integrated counterflashing. An uphill cricket diverts runoff around the back of a chimney where the design requires it. These are distinct details; step flashing does not belong in an open roof valley.

1. Water meets a chimney. The downhill apron sheds onto the shingles below. It is a different connection from the sloping sides.
2. One step per course. Separate metal pieces interleave with the shingle courses, working uphill along the chimney side.
3. Protect the wall connection. Counterflashing covers the upturned step-flashing legs, keeping water outside the wall connection.
4. Divert water at the uphill side. A cricket sits behind the chimney, toward the ridge. Its sloped faces split runoff around both sides; its need and dimensions follow the roof design.

Recorded guide: At a sidewall, metal steps overlap with each shingle course. Counterflashing or wall covering protects their upper edges and keeps water moving down.

Attic ventilation

A coordinated system pairs high exhaust with clear low intake. The selected vent style helps move air through the vented attic as conditions allow; intake remains essential with every exhaust choice.

Locate high exhaust near the top of the attic, with openings between framing members and the ridge clearance specified for the vent. Size its opening and intake capacity for the selected product, keeping one coordinated exhaust strategy within a connected attic.

1. High exhaust, clear opening. The vent connects near the top of the attic through its specified opening between framing members. Ridge clearance depends on the selected vent.
2. Low intake supplies the path. Clear soffit intake and baffles help preserve the air path above insulation.
3. Warm air and replacement air. Air can leave through high exhaust as replacement air enters below. The colors explain direction, not a promised temperature drop.
4. One coordinated strategy. Changing exhaust styles means choosing a coordinated system. Mixing competing exhaust types can draw air from another exhaust instead of the low intake.

Sunlight heats the shingles and deck. Heat can build in an attic when incoming and outgoing air have no clear path.

An unobstructed soffit-and-baffle path admits air below the roof. Exhaust alone cannot replace a properly sized, open intake path.

Warm air can leave through the selected exhaust. Static vents depend on conditions; powered vents add a fan with its own controls and intake requirements.

Competing exhaust styles can draw air from one another instead of the soffits. Peaked checks intake, attic layout and exhaust capacity as one system.

Recorded guide: Sun warms the roof. Fresh air enters low and leaves through the selected high exhaust. Clear intake and one coordinated exhaust strategy matter.

Lomanco attic ventilation principles

Hip and ridge caps

Dedicated cap shingles overlap across hips and ridges, finishing the meeting of the roof planes. The caps have their own exposure and fastening requirements.

Choose hip and ridge caps compatible with the selected field shingles and follow their exposure and fastening instructions. In the default box-vent system, caps finish the ridge without a ridge-exhaust slot beneath them.

1. Where the roof planes meet. Hip and ridge caps complete the roof after the adjoining field shingles are installed.
2. A dedicated cap product. A cap spans the peak and has its own exposure and attachment instructions.
3. Overlapping protection. Successive caps cover the attachment areas of the pieces beneath them.
4. Match the exhaust design. Caps cover a ridge vent only when ridge exhaust is selected. Other exhaust styles leave the ridge without that ventilation slot.

Recorded guide: Overlapping caps finish the peak, covering each previous piece's fasteners. They must match the roof system, including any selected ridge vent.

Manufacturer hip-and-ridge installation example

Drip edge, gutters and downspouts

The roof’s drainage route continues beyond the drip edge. Gutters collect runoff, downspouts carry it to ground level, and the discharge route directs it away from the home.

At the eave, underlayment laps over the drip-edge roof flange and the starter sits above it. Rake metal laps over the underlayment. Size the gutters and outlets for the roof they serve and local rainfall. Provide positive drainage to an outlet in the gutter bottom, connected to the downspout below.

1. Collect the roof runoff. Water leaves the drip edge and lands inside the gutter channel.
2. Flow toward the outlet. The channel directs collected water toward its low outlet location.
3. Enter the downspout below. Water drops through the bottom outlet into the connected downspout.
4. Discharge away from the home. The final drainage route carries water away from the foundation instead of pooling beside it.

Recorded guide: Follow the water into the gutter. It drops through the bottom outlet, travels down the pipe, then drains away from the home.

DOE building science: roof drainage

Box vents

Static metal box vents exhaust through high roof openings. They have no fan. Their operation depends on the available intake, air movement and pressure differences.

Turbines

Wind turns the turbine above a high roof opening. Air can leave through it as replacement air enters low. The illustrated rotation and air tracers explain the route, not a measured airflow rate.

Static domes

A stationary raised cover shelters a high exhaust opening. Like box vents, it needs a balanced, unobstructed intake path and suitable conditions.

Powered attic vent

An electric fan draws attic air out through its roof opening when its controls call for operation. Intake, wiring, controls and the building’s air-sealing conditions need review.

Solar attic vent

A solar panel powers the exhaust fan. In the illustration the fan slows as sunlight fades. Real output depends on sunlight and the selected product; a panel is not a promise of a particular attic temperature.

Ridge vent

A properly detailed opening beneath a compatible ridge vent provides high exhaust along the ridge. It requires a connected air path from low intake. A roof with an unvented or blocked vaulted assembly cannot use this arrangement as shown.

Protection in place. Tear-off begins.

Ground protection and safe access come first. The ridge caps are removed before the field covering is worked downward.

Work from the ridge down.

Old shingles and their fasteners are lifted from the upper courses toward the eave. Exposed underlayment remains a distinct layer below.

Expose the supporting deck.

With the shingles and starters removed, the old underlayment and replaced flashing details come off so the deck and roof openings can be inspected.

A sound foundation comes first.

Check the exposed decking and its attachment. Unsuitable or damaged panels need repair before the new protective layers cover them.

Give water a clean exit.

The eave drip edge is fastened to the deck before the synthetic layer covers its roof flange. Rake-edge integration follows its separate detail.

Protect the vulnerable details.

Self-adhered membrane bonds to the prepared valleys. Pipe openings and wall connections receive their own correctly lapped protection beneath the finished covering.

Dry in the roof, course by course.

Synthetic underlayment unrolls parallel to the eave, with higher courses overlapping lower ones. Lap widths and cap-fastener placement follow the selected product and roof conditions.

Start above the underlayment.

The selected starter assembly goes over the completed synthetic layer and below the first field-shingle course.

Build upward in stepped courses.

Field shingles advance from the eave toward the ridge. Product-specific exposure, stepped course starts and prescribed fastening keep the assembly working together.

Complete the roof connections.

Flashings are integrated as the adjoining shingle courses rise. Compatible caps finish the hips and ridges; box-vent flanges tie into the upper courses above their roof openings.

Follow the rain all the way down.

Shingles shed water into valleys, past the drip edge and into the gutters. Water enters the downspout through an outlet in the gutter bottom.

Give attic air a path through.

Sun warms the roof. Clear low intake and high exhaust allow replacement air to move through the vented attic; performance depends on the design and conditions.

The grounds deserve a final check.

The finishing checklist includes collecting debris, a magnetic sweep and a final walk-through. Protection and cleanup matter alongside the roof itself.

[Wind, rain]

Recorded guide: Let's protect what matters.

The system sheds water, together.

Overlapping shingles shed rain toward valleys and gutters. Broken sealant bonds can let wind lift an edge and drive water beneath that covering.

[Wind, rain, thunder]

Recorded guide: Overlapping shingles shed rain. Broken seals let wind lift their edges.

Hail can damage more than the surface.

An impact can dislodge protective granules or damage the asphalt and reinforcing mat. Size, hardness, wind and the roof condition all matter.

[Wind, rain, hail striking the roof, thunder]

Recorded guide: Hail can loosen granules and damage the shingle beneath.

Small granules. Important protection.

Granules shield the asphalt. An impact can dislodge them, exposing the coating to faster weathering.

[Wind, rain, thunder]

Recorded guide: Granules protect the asphalt from sunlight. Hail can knock them loose. Peaked checks for damage beneath.

Soft metals tell part of the story.

Dented gutters and vents are clues. Peaked compares them with the shingles and the rest of the roof.

[Wind]

Recorded guide: Dents in vents and gutters help tell the storm's story. We photograph these clues and compare them with the shingles. A dent alone does not determine coverage.

A lifted edge changes the water path.

Wind can drive rain beneath a shingle with a broken seal. Peaked checks creases, attachment and the protective layers below before recommending a repair.

[Wind]

Recorded guide: Watch the wind lift a poorly sealed shingle. Rain can be driven underneath that opening. Peaked checks the seals, fasteners, and flashing to find where protection failed.

Peaked looks beyond the obvious.

We document shingles, soft metals and vulnerable connections, then explain what needs attention. Decking that is concealed cannot be fully inspected until it is exposed.

Recorded guide: Your insurer decides coverage. We explain repairs.

Your property matters, too.

With the scope agreed and the work scheduled, protect landscaping and equipment, plan safe access and stage debris collection before tear-off.

Protective coverings surround the landscaping and equipment; the crew and collection trailer are staged before tear-off.

No additional weather sound.

Recorded guide: We protect your property before work begins.

Rebuild every protective layer.

Edge metal, targeted leak protection and lapped underlayment prepare the roof for starter strips and stepped shingle courses.

The roof covering disappears in successive stages from the ridge downward, leaving underlayment and then exposed decking. Rebuilding reverses the working direction: edge and leak protection, lapped underlayment, starter strips, stepped field courses, integrated flashing and vents, then caps. The installation sequence below explains each stage.

No additional weather sound.

Recorded guide: First, we remove the old roof and inspect the deck. Then we rebuild each layer, from leak protection and flashing to shingles and ventilation. It's a complete system, made to work together.

Water has a complete path off.

Valleys, flashing and gutters work together. The downspout begins at an outlet in the bottom of the gutter.

No additional weather sound.

Recorded guide: Follow the water into the gutter. It drops through the bottom outlet, travels down the pipe, then drains away from the home.

A connected path through the attic.

Clear low intake supplies replacement air to the selected high exhaust. Peaked checks the complete ventilation arrangement.

No additional weather sound.

Recorded guide: Sun warms the roof. Fresh air enters low and leaves through the selected high exhaust. Clear intake and one coordinated exhaust strategy matter.

Finish with care.

Collect debris, magnet-roll for nails, check drainage and walk the property together. The grounds matter as much as the roof.

A short illustrative clip shows a worker moving a magnetic roller across the grounds to collect stray nails. This is followed by the completed roof.
