If you have seen your asphalt shingles curl, it indicates that something
is amiss in your roof. Curling shingles not only are unsightly but can
also cause severe issues such as leaks, water damage, and inadequate
insulation. We assist Calgary residents in detecting such indications in
advance and repairing roofing problems before they become worse.
In this blog, we will discuss why asphalt shingles curl and how you can address it.
Wear and Aging Over Time
One of the most common reasons shingles curl is simply age. Most
asphalt shingles last 15 to 30 years depending on the quality and
weather exposure. As they get older, the protective materials break
down, causing the edges of the shingles to lift or curl. If your roof is
over 20 years old and you’re seeing curling, it may be time to think about
a full roof replacement.

Poor Attic Ventilation
Your attic plays an important part in maintaining your roof’s health.
If it is too warm or contains too much moisture, it can destroy the
shingles from the underside. Trapped heat results from poor ventilation,
particularly during summer, causing the shingles to dry out and
become brittle. Curling is usually one of the initial indicators. Straight
Path Construction can check your attic ventilation and make suggestions
for improvement to avoid further destruction.
Improper Installation
When the contractor who installed your roof is inexperienced or not
careful, curling shingles might be the reason. Installing shingles with
the wrong nails, improper placement, or omitting steps can prevent
shingles from lying flat. Eventually, they curl and lift, particularly in windy
or wet weather conditions. That’s why proper installation by
professionals like our crew at Straight Path Construction is critical.
Water and Moisture Damage
Shingles are engineered to keep water out, but when moisture becomes
trapped beneath them, they will warp or curl. This tends to occur
when ice dams build up during winter or flashing is not well sealed.
Once the shingles begin to curl, they allow more of the roof to be exposed
to water, which exacerbates the issue. Maintaining regular roof inspections
can aid in catching these issues early before they create leaks.
Low-Quality Shingles
All shingles are not created equal. Lower-grade shingles are not
necessarily durable enough to withstand Calgary’s elements, particularly
the cold temperatures, snowfall, and drastic temperature swings. If
your shingles are curling within just a few years of installation, they are
perhaps not of high enough quality to survive our regional environment.
At Straight Path Construction, we utilize vetted, weather-tolerant materials
that are engineered to withstand.

Frequently Asked Questions (FAQs)
Why do asphalt shingles curl?
Age, inadequate attic ventilation, improper installation, or retaining
moisture usually causes shingles to curl. All of these problems have the
potential to cause shingles to lift at the corners or edges.
Can curled shingles be repaired?
If just a few shingles are curling and the roof is otherwise in good
condition, repairs can be undertaken. But if numerous shingles are curling
or the roof is aged, replacement would be the preferable solution.
Is curling an indication that I require a new roof?
It might. Curling is usually a precursory sign of roof failure. If your roof
is older or exhibiting other forms of deterioration, it’s a good suggestion
to arrange for a professional checkup.
Will curling shingles produce leaks?
Yes. Shingles that have curled no longer flatten themselves and can allow
water, snow, or wind underneath them. This can result in leaks, mould,
or insulation damage if not repaired promptly.
