Is it normal for shingles to lift in wind?

In addition, high winds can “lift” shingles without removing them. Most often, this is caused by suction from the wind passing over the top of the shingles, rather than getting under them. In this case, your roof may look intact from the ground. But all the while, water is seeping underneath the loose, lifted shingles.

What do loose shingles sound like?

Flapping shingles in windy conditions can produce a variety of sounds described as flapping, popping, snapping, and on occasion moaning and howling as well.

Does it take time for new shingles to lay flat?

When the shingles heat up, they become flexible and the adhesive bonds the shingles in place. Before new shingles seal down, they can look a little lumpy and uneven, but once the roof gets hot enough, they should soften, flatten and form a permanent seal.

Why does my new roof look wavy?

When heated by the sun, the strip will cause the shingles to lay down and bond together. It is not uncommon for a new roof to look a bit wavy until this permanent seal is created. This is normally not a problem unless you experience windy conditions that can catch the shingles.

What does it mean when your roof is wavy?

A layer of felt paper goes down before the shingle does for every installation, which essentially acts as a base. If the material was damp, if the day was humid, or if the paper bubbled up a bit then it can produce a wavy appearance on your new roof.

Can a loose shingle cause a roof leak?

If your roof ends up with one or more seams exposed to the elements, they may let in water. Other critical parts of the roof are the valleys, or points where two low parts of the structure meet. Losing a shingle at a low point can cause water and debris to collect, increasing the chances for a leak.

How do you prevent shingles from blowing off?

You can change the direction of the exposed raised edge of the ridge cap shingles by installing them – in your case – from south to north, the opposite of your current state. If one direction of wind is more prevalent around your house, this may keep the shingles on the roof longer by keeping the raised edge down-wind.

The top shingle should be covering the bottom shingle's nails. Apply a dab of roofing cement to the nail heads to guard against leaks.

Why are my new roof 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 causes roof Zippering?

As the shingles expand and contract, they start to pull apart on the vertical lines they were installed on. This creates the zippering appearance as the shingles zig-zag up the roof. Other side effects of this substandard method of shingle installation include: Uneven color distribution.

How long does it take for roof shingles to settle?

The first, and more flexible, is that the outside temperature on the roof must be at least 40 degrees F for 24 consistent hours. The reason for this is that the adhesive strip will not activate and seal the shingle under colder conditions.

What causes a roof to ripple?

Improper Framing or Sheathing

Ripples can happen if the sheathing is installed without a gap between the boards to allow for expansion and contraction, or if the builder left the sheathing exposed to the elements for too long without covering it with a protective underlayment.

What is walking on my roof at night?

Why do roof shingles lift?

Why Shingles Lift. In most cases, asphalt shingles lift as a result of improper installation or inadequate ventilation in the attic. Shingles may have been damaged during the installation process or even before they were installed.

How can you tell if you have wind damage from shingles?

Signs of wind damage on a roof include loose or missing shingles, chimney issues, curling or peeling shingles, granule loss, damaged soffit or fascia and indoor leaks. High winds can also cause tree branches to fall and damage a roof. Like hail, wind can cause loss of granules (the sandpaper-like part of the shingle).

Can I replace just one shingle?

The shingles are cracked or torn – Shingles that are cracked can be replaced individually. However, if the crack or tear is minor, you may not even have to do that – you could simply have the shingle repaired with the use of roofing sealant.
