3 Tell Tale Signs You Need a New Roof
1. Granules in your gutters – this is a big indicator that the shingles on your roof are beginning to degrade. The granules on a shingle are designed to protect the asphalt layer underneath. Over time, the granules weather away, eventually exposing the asphalt to UV rays and elements. Once a shingle loses its granules, it is only a matter of time before replacement is necessary.
2. Moss growing between shingles – this is much more than a cosmetic problem. Moss means moisture has infiltrated your roof’s surface, and in cold weather climates, this moisture can lead to severe damage to your shingles. If moss has been allowed to grow unchecked for a long period of time, chances are you have much bigger problems underneath.
3. Curled or cracked shingles – both are signs of a huge problem. The asphalt in shingles is able to remain waterproof because of added low boiling point compounds. Over time, these compounds wear off and evaporate, causing shingles to become brittle and prone to cracking. Heat rapidly expedites this process. When shingles curl, it is due to being exposed to excessive heat from below – typically from an improperly ventilated and insulated attic. Poor attic ventilation and improper insulation drastically reduces the lifespan of your roof.
