Composite Roofing

The most widely used roofing material is the composite shingle. These shingles come in a variety of colors, designs and sizes. Depending on the product, the warranty can range from 15 to 50 years or “Lifetime.”  With a great value for the relatively low price it is no wonder why roughly 75% of roofs in Seattle are composite shingles.

Key Points

  • The most popular roofing material in the Puget Sound Area
  • Options include three tab, architectural and luxury shingles
  • Easy to install and maintain

Ridge Vent Detail:

The end of the ridge cap is given a clean finish.

Ridge Vent:

This product is installed on the ridges. A gap is cut at the ridge to allow air to flow into the ridge vent and then out of the attic space.

Gutter Edge Metal:

This metal is installed at all gutter edges. It helps the water to run into the gutter and not down the fascia boards. This also enhances the look of the roof by providing a clean, straight edge.

Roof to Wall Metal:

This metal is installed under the siding and on top of the roof.

Underlayment:

We install Safeguard 30® Hybrid Underlayment. This is five times stronger than a conventional 30 Lb. felt. It also lays flatter than felt paper, doesn’t blow off in high winds and provides much better traction for safer installations.

Chimney Flashing (Top):

As standard procedure we install new chimney flashing on both brick and wood siding chimneys.

Ridge Cap:

The ridge cap is installed on top of the ridge vent. This product should match the roof in color and thickness. Shown here is CertainTeed Mountain Ridge which is considered a “high-profile” ridge cap.

Roof Anchor:

This anchor is permanently installed and is used during the roofing process as a safety tie-off.

Drip Edge Metal:

This metal helps water drip off the roof without lingering on the fascia boards. This will prevent the fascia from rotting.

Sheeting (CDX/OSB):

CDX plywood is made of real wood veneer while OSB is an inferior version constructed with wood chips and glue.

Fasteners:

The key is to have hot-dipped galvanized nails. These nails are corrosion and rust resistant.

Tubular Skylight:

Often referred to as “Sun Tunnels” or “Solatubes” this is an easy and inexpensive way to allow natural lighting into a dark hallway, closet or bathroom.

Fan Vent:

Shown here is a 4” flapper vent that has an internal flapper that only allows air to flow one direction.

Furnace Vent:

This vent connects to either a furnace or a hot water heater and is often referred to as a “B” vent. Depending on its condition, it can either be re-used or replaced during the roofing process.

Ice & Water Shield:

This specialized underlayment is installed around roof penetrations like vents and chimneys where extra protection is needed.

Plumbing Vent:

This is a lead plumbing vent cover with a lead cap. Lead is pliable and doesn’t rust, making it perfect for this application. The plumbing vent itself is a PVC pipe that extends through the roof. Its purpose is to allow air flow through the plumbing pipes.

Valley metal:

This metal is called “W Valley” because of the ridge running down the middle. The ridge prevents water from running across the metal and up the other side. Without valley metal, leaks in valley areas are very common.

Starter Course:

The starter course is made of composition roofing material. It is installed around all perimeter edges to prevent water saturation.

Chimney Flashing (bottom):

As standard procedure we install new chimney flashing on both brick and wood siding chimneys.

Step Flashing:

These are 8”x8” pieces of metal that are hand-bent to bridge the gap between siding and roof.

Close up:

The product used here is 60 mil PVC in the color gray.

Cap Metal:

This metal gives a finished look to the roof. The color chosen here was white.

Underlayment:

We install Fanfold Underlayment for PVC roofs. This product serves as a vapor barrier while also smoothing out irregularities in the roof deck.

Membrane Breather:

This is a two-way breather vent employed to allow airflow between the roofing membrane and the roof deck.

Scupper Drain:

These drains go through the soffit area of the house and connect to the downspouts.

Screws and Plates:

The plates are barbed to stay in place. The PVC product is screwed into the roof deck.

Corner Detail:

Some up close welding detail.

Chimney Detail:

We replace the metal chimney flashing as standard procedure on most jobs. The PVC membrane runs up the sides of the chimney to prevent leaks.

Attic Vent:

This allows for attic ventilation.

Fan Vent:

These connect to the bathroom or kitchen fans from inside the house.

Plumbing Vent:

A pre-manufactured plumbing vent boot is installed around the existing plumbing vent pipe.

Corners:

These pieces are reversible and can be used on inside or outside corners. One side is gray and the other white.
