What's Under Your Shingles?
Tap any number on the roof to see each layer of a MichConn CertainTeed roof.
Self-sealing membrane on the bottom 6 feet of the roof from the eaves, plus the valleys, to stop ice-dam and wind-driven leaks.
CertainTeed synthetic underlayment covers the rest of the deck as a second water barrier under the shingles.
CertainTeed starter strip along the eaves seals down the first row so wind can't lift the edges.
CertainTeed Landmark architectural shingles, the weather-tight top layer you see from the street.
Matching CertainTeed hip and ridge caps finish and seal the hips and peaks.
Vent along the peak lets hot, moist attic air escape to protect the roof and lower energy bills.

Every Part of Your Roof
Tap any number on the roof, or any part in the list, to see what it does.
The wood framing that holds up the whole roof and carries the weight of snow and wind.
Plywood or OSB sheets nailed to the rafters that give every other layer a solid base.
Tape over the joints between deck sheets that keeps water from sneaking in at the seams.
CertainTeed RoofRunner covers the deck as a second water barrier underneath the shingles.
CertainTeed WinterGuard seals the bottom 6 feet above the eaves so ice dams and wind-driven rain can't leak in.
Metal edging along the eaves that steers water into the gutter and away from the fascia and deck.
The sloped edge of the roof at a gable end, trimmed and sealed so wind can't get under the shingles.
CertainTeed SwiftStart strip along the eaves that seals the first row down so wind can't lift it.
CertainTeed Landmark architectural shingles, the tough top layer that sheds water and that you see from the street.
Roofing nails placed in the right spot on each shingle hold the roof down in high winds.
Metal pieces bent around skylights, walls and other openings to direct water away from the gaps.
Metal that wraps the base of the chimney so rain can't run down into the attic.
Small L-shaped metal pieces woven in with each shingle course where the roof meets a wall or chimney.
Where two roof slopes meet in a dip; they carry the most water, so they get extra protection.
Rubber-and-metal collars that seal around plumbing vent pipes coming through the roof.
Box vents and other roof vents let hot, damp air out of the attic.
A vent running along the peak that lets hot, moist attic air escape all along the ridge.
CertainTeed ShadowRidge caps cover and seal the peaks and hips with a finished look.
Vents under the overhang that pull fresh outside air into the attic.
The sloped ridges where roof planes meet on a hip roof, covered with cap shingles to stay sealed.
The trim board along the roof edge that the gutters hang on and that closes off the rafter ends.
The finished underside of the roof overhang that protects the rafters and holds the soffit vents.
Catch water running off the roof and carry it to the downspouts.
Carry water from the gutters down and away from your foundation.
Windows in the roof that bring in daylight, sealed with their own flashing kit.
Air flows in at the soffits and out at the ridge to keep the attic cool and dry and help the roof last.
Keeps heat in your living space in winter and out in summer, which also helps prevent ice dams.
Parts marked "not shown" sit underneath or inside other layers.
