How Long Does It Take for New Shingles to Lay Flat?

Have you recently installed a new roof and noticed that the shingles aren’t laying flat?

This is a common concern for homeowners, and at CitySide Roofing, we understand the importance of a perfect roof installation. In this blog, we’ll explore how long it takes for new shingles to lay flat, why they may not be flat initially, and what you can do to ensure they settle properly.

Is it normal for new shingles not to lay flat?

Yes, it’s quite normal for new roof shingles not to lay flat immediately after installation. There are several reasons why this might happen:

1. Initial Installation: Shingles can appear uneven or wavy right after installation due to the way they are stacked and transported.
2. Temperature Fluctuations: Temperature changes can cause shingles to expand and contract, leading to a temporary wavy appearance.
3. Humidity Levels: High humidity can affect the adhesive on the shingles, causing them to take longer to settle.

Why Shingles May Not Be Laying Flat After Installation

New roof shingles not laying flat can be attributed to various factors:

1. Improper Installation: Incorrect nailing or placement can prevent shingles from settling correctly.
2. Substrate Issues: An uneven or damaged roof deck can cause shingles to appear wavy.
3. Weather Conditions: Cold weather can make shingles stiff, delaying the settling process.
4. Quality of Materials: Lower quality shingles may take longer to lay flat or may never fully settle.

Why Do My New Roof Shingles Look Wavy?

Wavy shingles are usually a temporary issue. Here’s why your new roof shingles might look wavy:

1. Thermal Expansion: As the shingles warm up, they expand, and as they cool down, they contract. This process can make them appear wavy until they fully adhere.
2. Moisture Absorption: Shingles can absorb moisture from the air, causing them to expand and create a wavy appearance.

How Long Does It Take for New Shingles to Seal?

Asphalt shingles typically take a few days to a couple of weeks to fully seal, depending on the weather conditions. Here’s a breakdown:

1. Warm Weather: In warm, sunny conditions, shingles can seal within a few days.
2. Cooler Weather: In cooler temperatures, it can take a couple of weeks for shingles to seal completely.
3. Optimal Conditions: Ideally, shingles should be installed in temperatures above 40°F (4°C) for the best sealing results.

How to Fix Lifting or Curling Shingles

If your shingles are lifting or curling, here’s how you can fix them:

1. Apply Roofing Cement: Use roofing cement to adhere the lifting edges of the shingles.
2. Add Roofing Nails: Secure the shingle with additional roofing nails, if necessary.
3. Replace Damaged Shingles: If the shingles are too damaged, replacing them might be the best option.

How Do You Flatten Curled Shingles?

Flattening curled shingles is a straightforward process:

1. Warm Up the Shingles: Use a heat gun to gently warm the shingle, making it more pliable.
2. Apply Roofing Cement: Lift the curled section and apply roofing cement underneath.
3. Press Down: Press the shingle down and hold it in place for a few seconds to ensure it adheres properly.
