Why Re-sheet Over Skip Sheathing?

Cedar shakes have always been a popular roofing material, especially in the Pacific Northwest. But in recent decades, the asphalt composite shingle has taken off as the main roofing style. Given the large numbers of homes with cedar shake roofs installed in the 1980’s and 90’s, many are coming to end of life now.

Most cedar shake roofs were installed over skip-sheathing, a poor substrate for asphalt composition shingles.  When a cedar shake roof needs replacing, the shakes should be removed, and the skip-sheathing sheeted over with solid plywood.

New GAF Cobra Hip Vent

Proper attic ventilation is essential in every home. If your attic is not properly ventilated, heat and moisture can build up, causing your energy bills to skyrocket. Moisture may not be penetrating your roof, but humidity from your home can still be trapped in your attic, causing mold and mildew to grow, and be absorbed by the rafters and the roof deck, causing rot.

proper attic ventilation is key for any roof systemOne popular solution for attic ventilation is soffit -ridge ventilation, such as GAF’s Cobra Intake Pro Rooftop Intake Vent and Exhaust Vent. This combination allows fresh cool air in and drives out warm moist air, promoting your homes energy efficiency. Since it is encouraging the exit of warm moist air, it also inhibits the growth of harmful mold and mildew, and prevents deterioration from roof rot. In addition, it prevents harmful ice damming on the roof during freezing temperatures. When installed with existing soffit vents, this system can improve attic airflow by up to 20%.

High Performance Underlayment

What is UnderlayementThere are many components that go into a new roof, and the quality of those products contribute to the over all performance that you will get out of your roof. Let’s face it, it rains a lot here in the beautiful Pacific Northwest, and waterproofing is essential to any project when it comes to the roof. For this reason, one of the most important aspects of any roofing system is the underlayment.

The underlayment is an extra layer of protection that goes between your shingles and the roof deck. This is an important aspect of any roof system because it protects the roof from penetrating moisture by shedding water away from the roof deck. It can also provide protection from rain while the shingles are being installed.

A Roofing Debate

We at Chase Construction NW, Inc. have been installing quality roofs around the Puget Sound for 15 years now, and have experience in a wide variety of roofing applications. We have seen a lot of debates in the roofing industry on different practices of installation, and today we are going to address one. The debate of nails vs staples is a hot one, and we definitely have an opinion! Both are approved by roofing manufacturers depending on what area you are in, but which one is better?

staples or nailsLet’s start with staples. Some roofers love them, some hate them, some are surprised that they are even still around for shingle installation. As far as ease of use and cost, staples are in the lead. It is much easier hauling around a much lighter staple gun vs a heavier nail gun, even the staples are easier to carry than the nails (as you can see from the picture to the right). Staples are also great for tearing off a roof because they come right up (that’s not a good thing). Yes, staples are easy to use, but it is difficult to install them properly. Staples must be put in in a straight line, and holding the staple gun straight is awkward and unnatural for the human hand resulting in crooked staples. When the staple is improperly installed, the result is a less than ideal wind rating, and the shingle is easily dislodged from the roof. Staples were very popular in the 80’s and 90’s, but since, they have been rejected by building codes due to the swarm of problems due to improper installation.
