What are starter shingles ?

Posted by Dan MacDonald on Apr 22, 2019 2:03:42 PM

After the appropiate ice and water barrier and underlayments are properly installed, installation of the roofing shingles begins with starter shingles on the eaves to protect the leading edge of the roof.

Visually , homeowners enjoy the design benefits a cohesive roof system provides. As a example, matching starter shingles allow the first course of shingles to blend in seamlessly with the rest of the roof. The same is true with ridge/cap shingles designed to match in color and shape, accenting the enhanced profiles and textures of laminate architectural or designer shingles.

Starter shingles are designed to increase protection against water intrusion and blow-offs. Installation of starter shingles is fairly straightforward for seasoned contractors. For three-tab and laminate/architectural shingles, cut 6" inches off one end of the first starter shingle. Apply the starter shingle on a lower corner of roof , overhanging the rake and eaves edges, including perimeter metal drip edge, by 1/4 to 3/4 of an inch. Making sure the starter is positioned with the factory-applied sealant strip face up and the strip adjacent to the eave edge of the roof. That then gets fastened with 4-6 nails 11/2 to 3 inches up from the eave, not in the seal down strip , with one fastener 1 inch from each side of the starter. The remaining nails should be evenly spaced on the same line as the end fasteners. Continuing the coures across the eave with full length starter shingles and butt them loosely together to avoid buckling.

After completing the underlayment, drip edge and starter shingles and all are in place , the roof is adequately prepared to start installing shingles. In addition to the cosmetics, using a single-source manufacturer allows roofing contractors to learn the precautions or limitations that could affect product compatibility and help avoid potential problems.

Roofing Valleys Correctly

Posted by Robert Evans on Feb 20, 2019 10:59:42 AM

Welcome to Robert Evans Jr. Contracting

Weaved Valley

Depending on your roof design you may or may not have valleys. A Valley is where 2 roof lines come together. Here is a picture of Robert Evans JR. Contracting Inc. installing a Weaved "Closed valley".  Closed valleys are those where shingles on one or both sides of the roof extend across the valley onto the adjacent roof slope. There is two kinds of closed valleys: cut valleys, which are less expensive to install {due to less waste in material and quicker labor install} and are the most common, and there are woven valleys as you see above in this picture. When Installing the woven method, shingles from both roof slopes run through onto the adjacent slope, alternating with each course. This is done differently with different types of roofing shingles depending on 3-tab, thickness, archtectural type shingles. Woven valleys is not recommended to be installed on a roof pitch less than 4:12.
