When Should I Replace My Roof in Longmont?

Many Longmont homeowners find it hard to know when to replace their roof, which is an important part of long-term home maintenance. There are a few triggers that can determine that it's time to get a roof replacement. For instance, recurring leaks and other kinds of damage can indicate that it's time for a replacement, especially when the damage is too extensive to be repaired.

In addition, due to the abundant sunshine in Longmont, a lot of homeowners choose to install solar panels every year. If you're installing solar panels, it's often a smart idea to replace your roof before installation, to make sure your roof outlasts your panels.
