Ridge Vent Detail:
The end of the ridge cap is given a clean finish.
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.
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.
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.
This anchor is permanently installed and is used during the roofing process as a safety tie-off.
CDX plywood is made of real wood veneer while OSB is an inferior version constructed with wood chips and glue.
The key is to have hot-dipped galvanized nails. These nails are corrosion and rust resistant.
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.
Shown here is a 4” flapper vent that has an internal flapper that only allows air to flow one direction.
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.
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.
The starter course is made of composition roofing material. It is installed around all perimeter edges to prevent water saturation.
These are 8”x8” pieces of metal that are hand-bent to bridge the gap between siding and roof.
The product used here is 60 mil PVC in the color gray.
We install Fanfold Underlayment for flat roofs. This product serves as a vapor barrier while also smoothing out irregularities in the roof deck.
This is a two-way breather vent employed to allow airflow between the roofing membrane and the roof deck.
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.
Some up close welding 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.
This allows for attic ventilation.
These connect to the bathroom or kitchen fans from inside the house.
A pre-manufactured plumbing vent boot is installed around the existing plumbing vent pipe.
These pieces are reversible and can be used on inside or outside corners. One side is gray and the other white.
