Frequently Asked Questions

  • Do Gutter Guards Work With Pine Needles in NH?

    Guard style matters. Hood-style covers like LeafLock shed pine needles off the panel surface rather than letting them collect in perforations. Open-screen products may allow narrow needles to enter or mat across the guard over time. Homes near pine stands in Rochester and Strafford County may benefit from a site evaluation to determine the best cover profile for their canopy.

  • Can Gutter Guards Cause Ice Dams?

    Gutter guards do not inherently cause ice dams, though a poorly fitting product can contribute to conditions that allow ice to form at the eave. A correctly installed guard keeps debris clear, so meltwater flows freely through the gutter and away from the roofline — less ice buildup than you would get from a clogged open gutter.

  • What Warranty Comes With a LeafLock System Installed by D & M Exteriors?

    D & M Exteriors backs its installations with a 25-year workmanship warranty. For specific product warranty coverage on LeafLock components, contact the team directly for details applicable to your project.

  • Do Gutter Guards Require Maintenance After Installation?

    No gutter guard eliminates maintenance entirely, but a hood-style system like LeafLock sharply reduces how often gutters need attention. Check them after heavy storms and at the end of each debris season. In heavily wooded areas around Rochester and the Lakes Region, a quick visual check each spring and fall helps confirm the guard surface is clear and water is draining properly.

  • Can Gutter Guards Be Installed on an Older Home With an Existing Gutter System?

    In most cases, yes. D & M Exteriors evaluates the condition of your existing gutters before installation. If the gutters are structurally sound and properly pitched, LeafLock panels can typically be fitted without replacing the full system. If the gutters show signs of sagging, pulling away from the fascia, or rust damage, the team will recommend repairs or replacement first to ensure the guard performs as intended.
