Architectural shingles are not designed for use as a starter strip, and may not provide the same level of protection and sealing capabilities as a dedicated starter strip. Using architectural shingles as a starter strip may compromise your roof’s overall appearance and aesthetic.
Can I use a shingle as a starter shingle?
The starter strip is the layer of shingles underneath the first course along the edge of the roof. Some roofers simply take regular shingles, flip them upside down and nail them down as a starter course.
How do you keep architectural shingles straight?
A chalk line can keep your line straight over long distances and large areas. A chalk line can help eliminate short exposures, waviness and additional antithetical issues. The first step in roofing is always to install the underlayment and any additional weather shields.
How much overhang do you need for starter shingles?
Shingles should not extend more than 3/4” (19 mm) past the drip edge. If shingles overhang the edge of the roof by more than 3/4” (19 mm), then they are not supported and may crack and break off. In addition, the wind resistance at the roof edge may be compromised.
Can you use architectural shingles for starters Related Questions
How much should starter shingles overhang drip edge?
Once the drip edge is installed, the shingles should extend ½ inch to ¾ inch past the drip edge. If the shingles are allowed to extend too far, then they can be caught by the wind and damaged.
Do I need a starter strip with architectural shingles?
You do need to use a starter course with architectural shingles. The starter edge will help seal the edges and cover your shingle joints. As it won’t be visible on the finished roof, you don’t need to worry about the look of your starter strip and whether it matches your architectural shingles.
What are starter shingles made of?
Starter strip shingles are long, narrow shingles typically made of asphaltic material. Roofers install them along the edges of the roof after installing the underlayment and before installing the regular shingles.
What is the difference between shingles and starter shingles?
Starter shingles are used at the bottom edge of your roof, while ridge shingles are used at the peak. Starter shingles have a shallow “cut” or “notch” so they lay flat against the roof decking, while ridge shingles have a deep “cut” or “notch” to allow for proper ventilation at the peak of your roof.
How do you calculate starter shingles on a roof?
Roof surfaces are measured in “squares”. A roofing square is equal to 100 square feet of the roof. To determine the number of squares on the gable roof example in this post, divide its total of 2400 square feet by 100 (2400 ÷ 100 = 24). This means you would need 24 squares of shingles to cover that roof.
Why do you need to strip starter shingles?
A shingle starter strip is an important part of a residential roofing system. It plays a critical role in reducing the risk of shingle blow-off along the eaves and rakes of the roof. It provides a base under the shingle at the eaves, helping the roof shed water efficiently.
Why are my architectural shingles not laying flat?
Asphalt shingles soften in the heat, which causes the shingles to bond to one another. This is what creates that flat look. If your shingles have not bonded yet, then they might look a little lumpy. However, this problem usually resolves itself after the shingles soften, usually in the warmer months.
What makes architectural shingles better?
Because of their durability and high-quality composition, architectural shingles generally have a longer lifespan than the 3-tab variety. They stand up better to weather conditions such as heat, snow, ice, rain, and strong winds. Their average lifespan is about 18 to 20 years.
Can architectural shingles be asphalt?
Architectural shingles are the most commonly used asphalt roofing material out of the three types of asphalt shingles. Not only are they the most popular asphalt shingle, but they are also actually the most common type of roofing material installed on roofs today.
Why avoid 3 tab shingles?
Three-tab shingles are weaker, less durable, and not as long-lasting. They can be subject to damage in areas or regions of the country that experience reoccurring bad weather.
Does the first row of shingles go upside down?
Starting at one end, place the starter shingles downside up so the self-seal strip is near the bottom. The top should be aligned with the chalkline and the bottom should be flush with the bottom of the underlayment.
When laying out three tab shingles how much shorter should the starter tab be?
Ensure they are positioned with the factory-applied sealant strip face up and the strip adjacent to the eave edge of roof. Cut 6″ (152 mm) off one end of the first starter shingle and lay it on a lower corner of the roof, overhanging the rake and eave edges by ¬º”- ¬æ” (6 -19 mm).
Should drip edge be tight to fascia?
A metal drip edge will help protect the sheathing under the roof, but if it’s installed too closely to the fascia board, it can still cause water to be drawn into the fascia. The best installation method is to leave a gap between the drip edge and the fascia board, about the width of a finger.
How far apart do you nail drip edge?
Nail the drip edge to the roof deck with minimum 12-gage roofing nails spaced 8 to 10-inches on center and 1-½ to 3-inches from the edge of the sheathing. Adjacent drip edge pieces should be lapped minimum 2 inches. Asphalt shingles should overhang the exterior edge of the drip edge by ¼ to ¾-inch.
Do you install drip edge before or after shingles?
Can Drip Edge Be Installed After Shingles? The most popular time to install a drip edge is when new shingles are installed. However, the drip edge can be installed at any time. The materials involved include: a ladder, a flat pry bar, a hammer, tin snips, eave stripping, and galvanized roofing nails.
