How Improper Roof Installation Can Affect Your Home? Zicklin Roofing

Proper installation of the roof is crucial as it acts as the first line of defense against the elements. There are several types of roofs, each with its advantages and disadvantages. The most common type, asphalt shingles, offers a good balance of cost, durability, aesthetics, and ease of installation. Proper roofing installation requires adherence to building codes, manufacturer instructions, and industry standards. Failure to do so can result in visible problems on the roof. 

However, not all roofing contractors have the same standards, and some may cut corners to save time and money. A poorly installed roof can cause significant damage to your home and pose a risk to your family. Therefore, it is essential to recognize the major signs of improper roof installation.

Add Your HeadingWarning Signs That Your Roof May Not be Installed Properly Text Here

A roof replacement is a significant and expensive project, and therefore, it’s crucial to ensure it’s done correctly. If you notice any of these signs on your roof, it’s essential to contact a professional roofing contractor immediately. Attempting to fix the issue yourself may exacerbate the problem and put you at risk.

As a homeowner, it can be challenging to identify mistakes made during new roof installation. However, it’s important to recognize that mistakes can occur, impacting the quality and lifespan of your roof. Below, we will discuss the telltale signs indicating your roof is not installed properly.

1. Uneven Appearance

You’ll likely notice any unusual appearance on your roof immediately. If it appears uneven or has abnormal bumps, it indicates that an error occurred during installation. A competent roofing contractor will ensure that your roof is level even before beginning the installation process. If you observe any unevenness in your roof after the job is complete, it suggests that the contractor took shortcuts.

An uneven roof can result in several issues, such as:

Pooling water:

When a roof is uneven, water may accumulate in certain areas instead of draining appropriately. This can result in leaks and severe damage.


Uneven roofs are prone to sag over time, especially if they’re not adequately supported. This can cause more water pooling and leakage.

Reduced lifespan:

Uneven roofs are more likely to experience premature wear and tear, leading to the need for early replacement.

If you notice any of these problems, it’s crucial to contact a professional roofing contractor immediately. They may be able to address the issue without having to replace the entire roof.

2. Missing Or Damaged Shingles

Improperly installed roofs can lead to missing or damaged shingles, which is a telltale sign of poor roof installation near me. When the contractor fails to secure the shingles during installation, they can easily come off, particularly during strong winds. Similarly, damaged shingles indicate substandard installation, either due to using faulty materials or damaging them during installation. Such missing or damaged shingles can leave your roof susceptible to leaks and other types of damage.

3. Mismatched Shingles

A bad roof installation can be identified by mismatched shingles. If the contractor used various batches or types of shingles, the shingles may not match in color or texture. As a result, your roof may look peculiar and be more prone to damage. Mismatched shingles may also come off more quickly since they do not fit together tightly, resulting in leaks and significant damage.

4. Home Damage from Excessive Leaks

Improper installation is a major cause of concern for roof leaks that lead to home damage. Leaks can occur at any point along with the flashing where shingles meet with rain gutters or downspouts and around window and door frames.

Water can damage the foundation of your home when the sealant, which is meant to prevent water from seeping in, either remains unapplied or deteriorates over time due to weather conditions and other external factors such as the accumulation of tree sap that hardens when exposed to air, thus leading to further complications.

 To prevent these issues, it’s essential to receive an in-depth explanation during your initial consultation about how the contractor will fix the problem before signing any contract.

5. Improper Gutter Installation

The gutter is where the extra rainwater from your roof is collected and directed away from your house. If the gutter is installed incorrectly, it may result in a number of major issues, such as:

Fortunately, this issue is typically simple to identify. A gutter that has been built incorrectly may droop or pull away from your house. If you notice this, have it fixed by a qualified roofing contractor.

To make sure your gutters are still in good shape, you should routinely inspect them. Even if they were properly fitted, they can eventually become damaged and need to be replaced.

6. Misuse Of Nails

Inadequate nailing is one of the major mistakes we see while installing asphalt shingles. Manufacturers of roofing systems provide detailed instructions on how to fasten shingles. Regrettably, some contractors seem to have trouble following such requirements.

Incorrect nail placement and overdriven nails are the two nailing flaws we discover most frequently:

Improper placement:

A nail is deemed high when it is nailed onto a shingle above the nail line. High nails are difficult to spot since they are frequently hidden by a row of shingles next to them, but they can be quite problematic. The nail won’t go through the shingle underneath a shingle that has been nailed too high.

Hammered nails:

To hold shingles firmly, roofing nails must be driven correctly and with the proper amount of pressure. If not, water might penetrate the shingles and start a leak. If it appears that your shingles have lifted, the nails may not have been set correctly.

7. Inclement Weather

The weather conditions during your roof installation can have a significant impact on the final result. If the temperature is lower than 40°F, it’s too cold to install a new roof. This is because the adhesive products used in installation need heat from the sun to activate. However, if you reside in a state with warmer weather, you could replace your roof during the winter. Although it may start at 20°F in the morning, the temperature could rise to 45°F+ by noon.

If it rains during roof installation, the plywood decking beneath the shingles can absorb water and swell. This makes it difficult for shingles to adhere properly to a wet deck. In case the shingles are placed on the deck before it dries completely, moisture can get trapped underneath, leading to wood rot. Wet weather can also cause mold and mildew growth on the deck, which can cause the wood to lose its shape and reduce the lifespan of your roof.

8. Stains On The Roof

When there are stains on your roof, it often indicates the presence of leaks. Such leaks usually occur due to the inadequate sealing of the roof by the contractor, allowing water to seep in and cause issues such as mold growth and wood rot. Additionally, such stains may also indicate that defective materials were used by the contractor during installation. For instance, if you observe black streaks on your roof, it could imply that the contractor used substandard asphalt shingles.

9. Absence of Drip Edges

The installation of drip edges, which are strips of metal placed along the edge of your roof, is crucial. They aid in directing water away from your home and avoiding seepage beneath your shingles. Roofers place drip edges beneath the shingles to provide the following advantages:

If your roof doesn’t have a drip edge, it could indicate that the contractor didn’t do a thorough job. Consider hiring a professional roofing contractor to install a drip edge to prevent potential problems.

10. Inadequate insulation and ventilation in the attic

Inadequate ventilation and insulation in your attic can lead to condensation and moisture buildup due to the conflict between indoor and outdoor temperatures. To prevent this issue, it’s essential to ensure proper ventilation in the attic.

A poorly ventilated attic can cause your roof to deteriorate within just two years, as it becomes vulnerable to damage from extreme temperature changes. This damage could result in leaks and other problems, significantly reducing the lifespan of your roof.

Proper insulation of your attic is crucial to maintaining the health of your roof, especially for homeowners living in colder regions. Inadequate insulation puts them at risk of ice dam formation, which occurs due to the continuous melting and freezing of snow caused by heat escaping from the home.

As the snow melts, water flows down the eaves until it reaches the unheated bottom edge or soffit area of the roof, where it refreezes to form an ice dam. Water buildup behind the ice dam can lead to shingle deterioration, decking decay, and water leaks in the attic and exterior walls. To prevent such damage, it is necessary to ensure proper attic insulation.

11. Lack of Maintenance

Neglecting regular maintenance is one of the leading causes of roof damage. Homeowners must understand the significance of routine roof maintenance and the potential consequences of disregarding it.

As roofs are exposed to the elements, they are susceptible to wear and tear. Without proper upkeep, small damages can escalate and result in significant issues.

Proper roof maintenance begins with inspecting the roof for visible damage, such as missing shingles, cracks, or rust. It is crucial to address any imperfections immediately to avoid further damage and costly repairs.

Regularly cleaning the gutters and downspouts is also an essential part of roof maintenance. Clogged gutters can cause water to accumulate, leading to roof damage. It is advisable to check and clear the gutters regularly of any obstructions or debris.

Roofer mistakes: Prevent poor roofing work before it arises

By taking the necessary precautions, you can prevent a poorly executed roofing job. It is essential to ensure that your roofing contractor conducts a comprehensive examination of your roof before beginning the installation process. This can help to avoid the following typical mistakes:

Failed to check the roof decking.

The roof decking serves as the foundation for your roof and supports all other components of the roofing system. As a result, it can deteriorate over time due to exposure to weather elements and require replacement. A skilled roofing contractor should inspect the condition of the decking and perform necessary repairs or replacements.

Failed to install new vents

Proper ventilation is crucial for preventing moisture buildup, mold, and rot in your home. Roof vents facilitate this circulation by releasing exhaust from various sources, such as hot water heaters and sewer lines. It is essential to avoid reusing old roof vents, as the nails driven into them may not align with the old holes, resulting in leaks. Hence, replacing old vents with new ones is necessary to ensure proper ventilation and prevent potential issues.

What Should I Do About a Poor Roof Installation?

If you have concerns about an incorrect roof installation, the initial course of action should be to contact the roofers responsible for the job and communicate your apprehensions. Even the most reliable roofers can make minor mistakes, and they are usually willing to examine the installation and rectify any errors. Review your roofing contract, as many of them contain warranties for these repairs.

If the original roofing company is unresponsive, it is advisable to hire a professional roofing company to inspect the roof thoroughly and identify any errors. This will aid in drafting a formal complaint to be sent to the original company. If no response is received, seeking legal advice may be necessary to consider litigation. It is crucial to prioritize getting the required repairs or a new installation done promptly to prevent any further damage to your home. 

The need for repairing or replacing a poorly installed roof depends on the specific issue at hand. Some issues such as improper material selection, missing underlayment, and inadequate nailing may require a completely new installation. This can be an expensive process for homeowners. However, there are options such as roof financing or pursuing legal action against the original roofer to help cover the costs of the necessary repairs or replacement.
