The answer to 'my architectural shingles is failing' is that there are several common causes, including improper installation, weathering and aging, and impact damage. Symptoms may include curling, cracking, or blistering of the shingles, as well as leaks or water damage in the home. Depending on the severity of the issue, solutions may involve repairing or replacing individual shingles, or in some cases, a complete roof replacement.
If the problem is caught early, some minor repairs may be possible as a DIY project. However, for more extensive damage or if you're unsure of the cause, it's best to call in a professional roofing contractor to inspect the roof and provide a recommendation. They can identify the underlying issue and determine the best course of action to restore your roof's integrity and prevent further problems.
