What GAF Shingles Can I Use For Low Slopes? Almost all GAF shingles can be installed on slopes as low as 2:12 provided that the shingle application instructions are followed as printed on the inside of the shingle bundle wrappers. Any slope limitations will be indicated in the instructions.
Are architectural shingles harder to install?
Easier Installation Despite the fact that architectural shingles are thicker than standard shingles, they are considerably easier to install. However, keep in mind that install time will differ depending on which roofing contractor you hire for the job.
What is the spacing for architectural shingles?

What is the minimum slope for a roof in the Philippines?
Most of the metal roofing materials can be installed on gently pitched roofs without leaking, where the minimum roof pitch typically is 3-in-12 (the roof rises 3 inches for each horizontal foot).
What is the correct roof slope?
International building code guidelines recommend a minimum roof pitch of 1/4:12. This means that for every 12 inches of the roof’s run‚Äîwhich is the horizontal distance it travels as it covers a home‚Äîthe elevation of the roof should change by at least 1/4 of an inch.
What is the best pitch for a shingle roof?
The short, simple answer is 2:12 has traditionally been considered the absolute minimum acceptable roof slope suitable for asphalt shingles. Asphalt shingles continue to be the most widely installed roof covering option in North America.
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.
How many years do architectural shingles last?
The different asphalt shingle roof types and their expected lifespans are: 3-tab shingles: The cheapest asphalt shingle type lasting between 15-30 years. Architectural shingles: Also called dimensional shingles, these asphalt shingles are mid-range priced and last between 20-30 years.
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 many layers of architectural shingles are there?
In most states, you’re only allowed to have 2 layers of shingles on a roof for fire safety reasons. However, you’ll still see roofs that have 3 or 4 layers today. If you already have 2 or more layers, a contractor will recommend a full replacement.
How many layers of architectural shingles can you have?
House roofs should never exceed three layers of shingles. Adding additional layers without excavation can save homeowners up to $1,000 in labor. Therefore, layering has advantages. Building and city codes require roofers to limit shingle layers to two.
How do you overlap architectural shingles?
Overlap each row by two inches. Sides should be overlapped by four inches. Use a bare minimum of fasteners; just enough to hold the underlayment in place for the next step. Make sure that you apply one layer of underlayment over the metal drip edge along the eaves.
Does GAF require drip edge?
GAF requires non-corroding metal drip edges at the eaves where a Silver Pledge® or Golden Pledge® Limited Warranty is sought. As a matter of good roofing practice, however, GAF strongly recommends that drip edges be installed at the rakes and eaves on all GAF shingle roofs.
How do you secure shingles to a roof?
For example: Hammer one nail about 2 inches from each end of a shingle. Then secure another nail an inch above each cutout. So, your next course of shingles should cover the nails by 1 inch vertically. As you continue, follow the pattern of lining a full shingle up against the next and then nailing it into place.
What is the first layer of shingles?
Starter Strip A starting layer of shingles lines the edge of every home’s roof. The starter strip is laid down underneath the underlayment to seal the edges of the roof. The purpose of this layer is to defend the rest of the roof against strong winds and reduce blow off.
What is the difference between shingles and architectural shingles?
Architectural shingles were created as a way to mimic wood shake or slate roofing, so instead of lying flat like traditional asphalt shingles, they instead feature some shingles that are made up of two layers laminated together in order to create a more contoured appearance.
What is the advantage of architectural shingles?
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.
What is the height of a shingle?
Roof shingles keep buildings watertight based on the principle of overlap and the principle of gravity. Years ago, most shingles were 36 inches long by 12 inches wide. These days, many roof shingles are a bit larger to save on labor as they are one meter in length or 39.5 inches long and 13 inches tall.
What is the ideal roof in the Philippines?
Slate roofs are ideal for the Philippine climates because of their durability. They can withstand heavy rains, strong winds, and extreme heat. They are also known to be fire-resistant. If you want a comfortable home during summer, go for light-colored slate tiles as they can deflect the sun’s heat.
