Shingles on Your Roof Curling? What Causes This and How a Roofing Company Can Help

If your roof doesn't look so good, there could be a number of reasons. Before you contact a roofing contractor for help, learn why this is happening so you can avoid it before you call the contractor to install a new roof.

Improper attic ventilation

Roofing work doesn't just start with a simple roof tile. It's important that the vents are also in good shape. These vents can keep your attic at the same temperature as the air outside your home. Without them, excess heat and humidity can cause the tar in shingles to lose its adhesion, allowing them to shrink and curl.

Improper nailing by the roofing company.

Before you hire a Oakville roofing company, make sure they know what they're doing. If the roofing is not installed correctly, you could have a major problem well before the warranty expires. Every roofing shingle has a nailing diagram that must be followed to install it correctly. Without this, shingles can fall down and curl. Before you hire a contractor, ask him how many nails he uses for each shingle. It's important to use four nails, so if the contractor says he'll use three, you may have a problem.

High nails

As the home expands and contracts due to weather changes, the nails may start to sit upright as the deck moves them outward. If you have an older roof, this can happen simply due to age, and not necessarily due to poor installation. However, if your home is fairly new, you may need to contact a roofing contractor to determine if this is due to poor workmanship.

Inferior roofing shingles

Many homeowners prefer to work with a qualified roofing contractor, but it's also important to choose quality roofing shingles. Don't be tempted to choose the cheapest you can find, as they are often inferior. A good roof tile will have a quality tar line that acts as an adhesive to other materials, and a poorer roof tile may have a weakened tar line that can lead to curling, even if installed correctly.

Freezing

Freezing occurs when there are ventilation problems in the attic. Without proper ventilation, snow and ice can melt and run down the roof until stopped by unthawed ice. Water then gets trapped, where it stands still and seeps into the roof sheathing. This loosens the glue and causes the roofing to curl.

What to do if shingles curl?

If your shingles curl, it's only a matter of time before you need a new roof. It's best to call a roofing contractor immediately, before problems occur inside your house. An unprotected home is prone to water damage, mold growth, and more. By the time you notice wet spots on your roof, it can sometimes be too late, because water will travel through your roof, attic insulation, and floorboards before you know it.If your shingles curl, it's only a matter of time before you need a new roof.
