Upgrade Your Roof with Architectural Shingles

One of our recent EHT projects was a DIY “roof-over,” in which we covered an existing single layer of three-tab asphalt roof shingles with architectural shingles.

In roofing, the term “architectural” generally means the shingle has a three-dimensional design and construction. A true architectural shingle will have more than one thickness to provide enhanced aesthetic appeal. The dimensional design creates a shadow line that gives the roof the appearance of slate or wood shake. Not only does the three-dimensional design enhance the look of the roof, but the extra thickness of the shingles provides additional weather protection.

For this project we chose the StormMaster Shake shingles from Atlas Roofing. These designer roof shingles resist high winds, harsh impact and extreme weather conditions. StormMaster Shake also features Scotchgard Protector to defend against those dark, dingy streaks that appear on your roof due to algae. With the algae threat removed, your home’s roof keeps the original color. Scotchgard Protector roof shingles resist cracking, splitting, warping or shrinking in both hot and cold weather climates for many years.

As always, check with the manufacturer and your local building inspector about code requirements for roof work in your area. Some manufacturers don’t warranty their product if installed over existing shingles, and a new layer should never be installed over any more than a single layer of old shingles. For this job to meet local code and the manufacturer warranty, we had to first cover the old shingles in 30-lb. felt paper before roofing installation. It’s also important to follow the manufacturer’s instructions to the letter regarding shingle layout and fastener placement.
