How to Install Cedar Roof Shingles to Ensure a Leak Free Review and to Maximize their Lifespan
By Mark J. Donovan
|Cedar roofing shingles and shakes offer a number of advantages over other roofing materials. Cedar roofing shingles provide a natural elegance and have excellent insulation properties compared to other shingle products. In addition, in some cases it may be possible to install cedar roof shingles over existing roofing material. Cedar roof shingles are insect resistant and are extremely durable and strong.
As a matter of fact, installing cedar roof shingles actually strengths the structural integrity of the roof. Cedar shingles can have a lifespan from 20 to 40 years depending upon the local weather environment, the slope of the roof, and how regularly the shingles are maintained.
The more arid the climate and the steeper the roof slope the longer the lifespan of the cedar shingles. Cedar shingle maintenance is minimal. Periodically cleaning and the application of a protective finish should be applied to them to maximize their lifespan.
|To install cedar roof shingles start by making sure dry weather is in the forecast. To prepare the roof for the cedar shingles first apply roofing felt interlay paper over the roof battens. When installing cedar shingles on the roof make sure the thick side of the shingle is placed towards the bottom.
Also always start at the bottom of the roof, at the roof eaves, when installing cedar roof shingles, and work upwards to the ridge. Also, at the roof eaves the cedar shingles should be doubled or tripled.
The first course of shingles should extend approximately 1-1/2” beyond the fascia board and about 1 inch over the gable or rake end of the roof. Two non-corrosive nails should be used for each shingle. The nails should be installed approximately ¾ inch in from the side edges and about 1-1/2” above the exposure line.
Finally, any flat grain shingle that has a width greater than 8 inches should be split into two pieces before nailing.
