How to Install Copper Cat Roofing Strips

After putting down the underlayment, bend your trim to fit each unique edge of the roof. These trims are eaves, sidewall flashing trims, mono-pitch ridge gaps, and gable trims.

Once crafted, attach the trim to the facia and secure it to the roof deck with 1-inch roofing nails. Where the trims meet, secure them together with weatherproof sealant.

Before setting your paneling, place a foam closure strip with adhesive where the trim meets the edge of the paneling. This prevents insects and water from getting under the panels.

A zinc strip can be installed on a roof to prevent moss from growing. The zinc prevents the growth of the moss as the strips become corroded from moisture. The corrosion releases the zinc. The moss is incapable of digesting the moisture containing chemicals in zinc and is then incapable of growing. Zinc strips not only prevent the growth of moss, but they prevent the growth of mold and mildew as well. The strips are eco-friendly and cause no harmful damage to the environment. They may, however, cause damage to any plants growing on the ground near any runoff from the roof. Follow the simple steps below to effectively install zinc strips on your roof.

Step 1 – Safety

Put on your protective eyewear, work boots and work gloves before you begin. Be careful moving up and down the ladder. Always be cognizant of the roof edges while you are working. Be sure to have a family member or friend with you while you work.

The Truth About Zinc Strips

By | Submitted On March 15, 2009

Many roof cleaning companies will offer to install zinc strips on your roof for a hefty price tag. The question is, are they really worth it? Do they actually work? Many times the zinc strips are sold with a promise that the moss will not come back for 5-7 years. Let’s see if this is really true.

Awhile ago, our company received a call from a person who had purchased the zinc strips. This person in particular was sold the strips claiming that her roof would be moss free for 7 years. Upon inspection, it was plain to see that it didn’t take the moss very long to grow back. It’s been our observation that even when the zinc strips are installed correctly, in most cases they are not, the moss killing properties only covers a few feet below the strip. After awhile the zinc strips curl and wear, losing their moss killing value.

We do not recommend the installation of zinc strips. We recommend hand brushing in order to preserve the life of the roof. A professional company can remove the moss without damaging the roof. And one thing a person should always keep in mind is NEVER allow someone pressure wash your composite roof.

How Zinc Strips Work

Since simple plant life forms are the main culprit in deterioration, their reduction is the logical approach to preservation. Metals like zinc, copper, and some kinds of galvanized steel are poisonous to simple plant life. On a sloped roof, these can be used to control moss. The idea is to place them near the top of the field of roof on which you want to control the moss. Rain water runs over the metal and down the roof field. As it rolls over the metal, the water picks up molecules of metal, and carries them down the roof. The wetness triggers the moss to feed and drink, but the metals damage the moss.
