Why are my Orlando Asphalt shingles curling and cupping? Is a question we are often asked here at Schick Roofing.
Understanding why your shingles curl and cup and how to prevent it from happening in the future.
Curling is when the edges of the asphalt shingle turn up, but the center may still be flat.
Cupping is the shingle forms a cup in the middle, they will have a depression or concave in the center.
Both Curling and Cupping are a sign of a problem that needs attention before it becomes an emergency.
So, how does it happen?
Installing the Right Shingles
There are many different types of asphalt shingles on the market. Here in Central Florida your shingles need to able to handle extreme heat and high winds. If not, curling can occur, significantly reducing the lifespan.
Lack of Venting
Your roof is made up of several layers, a deck typically made from plywood, underlyament, and asphalt shingles. These layers are what makes a durable roof, but they also keep moisture and heat from escaping, which cause shingles to cup and curl.
When a roof is improperly vented it not only reduces the life of the roof, it leads to higher electric bills, increase in mold and mildew, and structural damage. Proper venting, such as attic fans, allows moisture to escape and reduces energy costs by keeping the temperature cooler.
A reputable roofing contractor will ensure the shingles are handled properly before they are installed. Poor storage, overheated by exposure to the sun or saturated by the rain, will weaken the shingles and cause them to age prematurely.
Inadequate Binder Coating
There is a problem if your shingles start cupping or curling within the first year of installation. Whether it is with an inadequate amount of binder coating applied to the back during installation (which makes them more resistant to UV damage) or faulty shingles, you will need to have the roof inspected.
