Asphalt Shingle Roof Repair

While shingles are a great roofing choice, there are some common issues with this material that you may or may not experience during your roof’s life.

We are able to perform all types of Shingle Roof Repairs.

Below are the most common Shingle roof Repair issues we fix:

Missing Roof Shingles

Since shingles are installed piece by piece, it’s possible for individual shingles to unattach and/or come off the roof.

This can happen for many reasons, including:

A strong wind lifted the edge of the shingle and disengaged it.

Something impacted or hit the roof and caused the shingle to disengage.

The sealing on the back of the shingle (black strip in the middle of the shingle) is broken/brittle.

The shingle was installed at too low of a temperature, and the seal couldn’t become engaged.

The seal was never properly engaged in the first place.


Shingle Blistering Repair

One of the most common asphalt shingle issues. This happens when moisture trapped within the shingle expands and pops/breaks through the surface and creates an exposed spot. Most of the time, blistering occurs during the high-temperature summer months.

Another reason for blistering is poor ventilation of the roof that creates trapped moisture. Improper ventilation is the cause of many shingle roofing problems,

Blistering exposes your roof, decking, and property to the elements, which can ultimately lead to leaking and premature failure of the roof system.

Shingle Roof Curling

If you can see the edges of the shingle lifting off the roof’s surface or the corners turning upward, you’re seeing curling.

There are a several reasons that your shingles are curling, including:

The shingles are nearing the end of their useful lifecycle. Eventually, shingles will start to shrink up and curl, which is a sign that it might be time for a new roof.

The shingles were improperly installed. For example, misaligning the shingles during the installation or roofing over existing shingles that weren’t level (without a roof tear-off) could cause curling.

There are existing ventilation issues where trapped moisture has caused the shingles to curl.

One of the most popular reasons that shingles curl is due to a thermal shock, when the high temperature of the roof suddenly cools rapidly. For example, if you have a warm day, the roof temperature will be higher because shingles absorb a lot of heat. Then, perhaps the weather quickly changes, cools down, and causes the roof to drop in temperature. This thermal shock can affect your shingle roof and start to create a curling effect as it happens over and over.


Roof Shingle Cracking

Cracking is a natural part of the aging process for shingles. Over time, wind, roof stresses, thermal movement, and deck movement aid in a shingle cracking. So, if  surface cracks don’t completely split or tear through the shingles, it’s most likely because the shingles are older.

Not to compromise the water-tightness of the roof, get us to fix it in time.


Roof Shingle Granule Loss, It happens is where the top layer detaches from the shingle and falls off.

All shingle roofs will experience some level of granule loss over time due to weathering and exposure. However, if a large number of granules are in your gutter or specific spots of your roof are missing significant granules, it could be several causes, including:

The asphalt in the middle layer was not applied evenly or consistently throughout the shingle and has created an adhesion issue.

The roof overheated, melted the asphalt, and caused granule loss.

The roof is not properly ventilated, so there’s a problem in the property itself, the attic space, the insulation, or beyond.

If granules fall off at a high rate and the problem isn’t addressed, it can lead to clogged or blocked gutters, overall UV damage to the exposed shingle, leaking, or roof failure.


Mold, Mildew, & Algae on the Shingles 

These occurrences are especially common in high-humidity areas and on northern-facing roofs that are heavily shaded or rarely get sun.

Most of the time, the algae, mildew, and algae, which often looks like black streaks down a roof, are cosmetic issues that can be remedied. There are anti-algae shingles available for purchase if you’re concerned about organic substance growth. Some shingles contain copper and zinc metal ions that can help to reduce algae growth. You can also purchase solutions specifically designed to clean roofs with mold, mildew, or algae stains.


However, if the problem persists, these organic substances can cause the roof to trap moisture. Trapped moisture can wreak havoc on the roof underlayment and even rot out a plywood or OSB roof deck.

Green Leaf Roofing LLC will fix all the Issues explained above.
