Top 5 Reasons why Asphalt Roof Shingles Curl in Downey


Learn why your Asphalt Roof Shingles are curling & how you can fix the Problem

Curly shingles are a typical roof problem. Once they have curled up, they will slowly expose the roof below and do a lot of damage.

In some cases, you may need to replace the curly shingles with new ones. Or if the damage is too extensive, you may need a completely new roof. Below you will find the reasons why shingles start to curl and the solutions.

Curly and cupped shingles are an indication that something is wrong with your roof. Cupping occurs when the center of the shingle becomes concave or depressed so that the shingle forms a cup.

Curling is when the edges are raised. If you notice cupping or curling in your asphalt shingles, you should call a reputable roofing company right away for an inspection.

*Why do shingles curl?

There are five reasons why shingles curl.

  1. Incorrect installations

Improper installation of roof shingles is the most common reason why shingles have started to curl. They could be the result of not following the installation instructions. The nails used were of poor quality, the quantity used was not sufficient to hold the shingles securely, or the length was incorrect.

In these cases, they will quickly lead to an increased susceptibility to the shingles coming off the roof. If the nails are not lined up correctly or used in the wrong places, they will also cause damage and cause the shingles to buckle.

  1. Poor ventilation

Moisture build-up caused by poor ventilation can become trapped between the materials that insulate the roof and attic.

That moisture has nowhere to go but up, causing the build-up to dampen your roof shingles and, over time, curl them. Moisture can also cause mold growth and cause many health problems for you and your family.

  1. Wear and tear over time

Shingles are installed with a forty-year or even lifetime warranty, but wear and tear vary, and sometimes they will need to be replaced before the warranty expires. The roof foundation may need repair and replacement before the shingles start to show damage.

In these cases, it may be advisable to install a completely new roof. But you can extend its use if you are interested in maintaining all the other factors that could lead to premature wear  and tear of your roof. This includes making sure your windows are in good condition, as well as your water pipes.

  1. Materials used

Sometimes the problems stem directly from the materials used to make the shingles. One of the drawbacks of hiring unregistered contractors is that, they buy defective materials to make more money. Don’t make the wrong decisions by cutting costs that could result in double spending in the long run.

If you start with high-quality materials recommended by professional contractors, the quality will meet your expectations and cost you less money in the future and even fewer headaches.

  1. New roof installed over old

In some cases, contractors will not need to remove the old roof to put on the new one. If the old roof is strong and free of water damage, a new roof can be installed over the old.

Problems start if the locking of both tops is not secure and if there was damage to the old roof that went unnoticed. But in most cases, if installed correctly, the additional roof should add additional protection to the one below.

*How to fix curled shingles

Curling shingles are different than a few shingles falling off. If your shingles are curling then there are underlying issues that are causing the damage. Here are the steps a roofing contractor will take to repair your roof.

First, they will raise the lower shingles to access the roofing nails. Some roofs still have the old ones under them.

If this is the case for your roof, the contractor should check to see if the damage is on both roofs. If so, you may need to consider replacing the entire roof with new shingles.

*Removal and replacement of shingles

The next step is to drive out the roofing nails with a flat nail bar. Damaged curled shingles are made to slide down, exposing the top edge. They are then removed.

The damaged shingle is now replaced with a matching new one. Roof sealant is applied to the part of the new shingle that connects to the other.

The new shingles are attached securely with four 1 1/4-inch roofing nails. Roofing sealant can be used on the head of each nail for added strength.

An increase in your electric bills may indicate a crack or opening in your roof that is allowing moisture to collect. These may be the reasons why your ventilation system has been fluctuating.

And your heating system seems not to be enough to keep your home warm during the winters.

Don’t hesitate to request a roof evaluation to prevent further damage to your roof. The longer damage is left unrepaired, the more it will cost, not to mention additional damage inside your home.
