Six Signs of a Quality Cedar Roof Installation

Can Cedar Roofs be installed with a nail gun?

A nail gun can be used to install all wood roof “systems”. The pressure of the air compressor should be regulated to ensure proper installation. The head of the nail should be driven flush with the surface of the shake or shingle being used.

Why are so many nails used per piece, isn’t it bad to put more holes in the wood?

Each shake/shingle is installed with two nails per piece. Additional nails penetrate the wood from the overlapping courses and together help to hold it securely in place.

What type of fastener should be used?

The Cedar Shake and Shingle Bureau recommends that roofs and side walls be installed using nails as opposed to staples. They also recommend a stainless steel fastener because of them being the least corrosive. NEVER use an electro galvanized fastener with cedar shakes or shingles. This type of fastener is not compatible with cedar products and will deteriorate quickly allowing for pieces of wood to slide out of their setting.

Is it natural for the shingles to fall from my roof from time to time?

The simple answer is NO. This may be a sign of electro galvanized fasteners. These nails were common for cedar shake and shingle installation from 1999 to 2006. They are not compatible with the cedar and will rust where they make contact with the wood. In most cases the roof can be refastened with stainless steel nails avoiding premature replacement.

Is venting my Cedar roof necessary?

All roofing products regardless of composition require proper ventilation. This will help disperse the accumulated hot air that builds up in the attic space. The roofing material will have a longer life span as a result. In the colder months, ventilation helps combat ice damming which is a common problem in our region.

How do I know if my roof was improperly installed by another contractor? If not, can it be corrected?

If you have an issue with an improperly installed roof the largest telltale sign is leaking which can be repaired. The next thing to look for is excessive cupping and curling of the shakes/shingles and loose or falling shakes/shingles. An evaluation of the roof will need to be performed to realize the issues at hand. Depending on the defect of the installation determines the course of action. In some cases the roof may be a candidate for renailing but in others; the roof may require full replacement or continued repairs throughout its life.
