Read Our Frequently Asked Questions

When you face any roofing issues related to replacement, repair, or maintenance, you come across various queries. Affordable Roofing Inc. presents a list of frequently asked questions, where you find the answers to some basic questions and get clarity.

Why are my shingles curling?

Asphalt, an oil-based product, is resistant to water and used in a wide range of waterproofing areas. The majority of shingles used today are primarily asphalt in construction, and asphalt does dry-out over time, which is known as oil migration. As with most natural elements, when asphalt dries, it shrinks. That’s why shingles have a fiberglass intermat that tries to prevent shrinkage.

Over time, though, the intermat will begin to fail as the asphalt expands and shrinks, and that is when you start to see curling. Other factors like improper ventilation accelerate the curling process by giving the asphalt more periods of frequent movement. When curling occurs, accelerated damage can occur to your roof, it may be time for a new roof.

What is granular loss?

Shingles use small colored stone chips called granules to protect the asphalt from environmental elements (such as UV light) and to provide an aesthetically pleasing look. Over time these granules wear off, and when this occurs, the asphalt surface starts to break down, causing a downward turn in the shingle’s life. This is the reason why it is not recommended to pressure clean a shingle roof.

We have found improper ventilation to be a significant cause of premature granule loss. And, as an added precaution, it is also important to keep overhanging trees trimmed so they LAO don’t brush off granules. If you notice shingles going bare, that means that a roof replacement is near.

What are the results of standing water on my roof?

Ponding water is a code violation and warranty exclusion on all asphalt-based roof systems. This is categorized when water sits on a roof for more than 48 hours without evaporating or running off naturally. Water ponding breaks down asphalt, which is an oil-based product. The issue with ponding water is that oil is trapped at the bottom, and due to its natural properties, it tries to rise to the top, causing oil migration. When the oil is then pulled out from the material, it starts to lose its waterproofing ability and then, in turn, causes the system to break down.

Why do I get torn, cracked, or broken surfaces on my roof?

As a roof expands and contracts, the components that hold it together, begin to push and pull against one another. This is a daily occurrence and is associated with thermal shock, and after years of this type of movement, something usually gives. Other factors can be purely kinetic, such as a tree branch or flying debris that may impact the roof; or third-party damage such as foot traffic can cause damage. When the membrane is damaged, this can lead to leaks. Hence, it is recommended to get it patched or repaired as soon as possible.

Do I get a warranty when I get a new roof?

We proudly stand behind our work. And, to give you peace of mind, we offer a standard 5-year workmanship warranty on the roofs that we install. This goes hand-in-hand with the manufacturer’s warranty.

Do I need to install gutter guards on my roof?

They are more than worth the investment if you have trees or other foliage that are tall enough to blow onto the roof. They virtually eliminate clogged downspouts, and leaf build-ups in the gutters.

How can I stop ice dams from forming on my roof?

The best prevention of ice dams is a well-ventilated roof, also known as a cold roof. Make sure your attic area has sufficient air exhaust outlets (gable vents, ridge vents, and free air vents) and that the airflow is distributed throughout the attic space. Peak mounted ridge vents such as Shingle Vent II, maximize airflow in attic areas.

Homes and buildings with cathedral or open ceilings may want to consider installing ceiling fans near the peak of the ceiling to help push the warmer air away from these areas.

How do I stop moss growth on my roof?

Moss growth is an abundant issue in the Midwest, usually noted by black streaks on shingles. They become more noticeable as your roof ages. There are many ways to deal with moss, the easiest being a water-bleach mix wash if your roof is already showing signs of growth (do not pressure wash). The preventative measure is to install zinc or copper strips on the ridge of the roof to inhibit moss growth.

How can I deal with mold growth?

The best way to deal with mold is to prevent its growth. This can be done usually through a well-ventilated and dry attic, keeping a low humidity level in your insulated space. Mold, unlike moss, does not need sunlight to thrive and appears as black spots inside your attic and as black streaks on your shingles. Once mold has taken root, a licensed mold remediator is your best bet for mold removal. If mold growth has been left unchecked, it can rot away the plywood, and repair expenses could skyrocket. So, it is always best to do preventive maintenance or call a professional as soon as you see early signs of mold.
