The answer to 'architectural shingles clogged gutters' is that this is a common problem caused by the granular texture of architectural shingles. As the shingles age and weather, their granules can break off and accumulate in the gutters, causing blockages and backups. This can lead to water damage, roof leaks, and other issues.
The main symptoms of this problem are visible debris in the gutters, water overflowing the gutters during rain, and staining or damage to the roof, fascia, or siding. To address it, you'll need to regularly clean out the gutters to remove the buildup of granules and other debris. This is typically a DIY task, but if the gutters are difficult to access or the debris is extensive, it's best to call in a professional roofing contractor to handle the job safely and effectively.
