Three-tab shingles are lightweight and easy to install. They’re thinner and look more two dimensional than three dimensional after installation. Usually, three-tab shingles will not last as long, but they are cheaper than architectural shingles.

What happens if you nail shingles too high?

When the shingle is nailed too high the nail does not penetrate the shingle below it. High nailed roofs are easily blown off in windy or stormy conditions because the roof isn’t ‚Äúconnected‚Äù like it should be. Inadequate nailing means big reduction in wind rating.

Why are my 3 tab 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.

Do you overhang starter shingles?

Whether installed at the eave or the rake, the starter shingles should overhang the edge of the roof by ¼ inch to ¾ inch. Typically, the finish shingles are then installed to align with the edge of the starters.

Do you overlap drip edge?

Nail high up on the drip edge so that the shingles will cover the nails. Ideally, you’d nail about every 12 inches, and in no circumstances should you have 16 inches or more between nails. When you place the next drip edge piece, it should overlap the first by an inch.

How many nails per square for 3 tab shingles?

Are 3 tab shingles good?

How do you keep shingles straight?

Keeping the Roofing Line Straight e shingles aligned vertically and horizontally. 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.

How far do you overhang 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.

What is the life expectancy of a 3 tab roof?

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.

Can placing nails in the adhesive strip lower a shingles?

Placing nails in the adhesive strip can cause the shingles to fail to seal properly, reducing their wind resistance. Placing fasteners above the adhesive strip, called ‚Äúhigh-nailing,‚Äù will also reduce the shingle’s wind resistance. On strip shingles, fastener placement should be limited to areas within the green strip.

Can I use regular nails for shingles?

You cannot use screws for roofing shingles, only roofing nails are approved fasteners. Screws leave small gaps in the material they are driven into, and this may be enough to allow for a leak.

What happens if you don’t stagger shingles?

Stagger Is Important If the stagger (offset) is not adequate, rain can move through the edge of the shingle to the edge of the lower shingle, creating a leak. This is especially problematic in wet climates, areas with heavy rain or areas with freeze-thaw cycles, and with lower slope roofs.

Why should you over hang your shingle a half inch?

Ideal Overhang Length 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. If they do not extend far enough, driving rain can get under them and damage the roof deck.

Does it take time for new shingles to lay flat?

The shingles need exposure to sunlight and warm temperatures so they can “relax” and lay flat. Depending on temperatures, this process can take from one week to several months.

What happens if shingles are incorrectly installed?

Installing shingles too high or too low compared to the previous course can affect the exposure, which in turn would affect the aesthetics, wind performance and seal strength of the roof. An improperly aligned shingle course would be very noticeable and have a wavy appearance that is unattractive and amateurish.

Do shingles go over or under flashing?

Flashing should overlap the roof-covering material, but on asphalt shingle roofs, for aesthetic reasons, the part of the headwall flashing that extends down over asphalt shingles is often covered with a course of shingle tabs.
