Gutter guard installation: what to know

What the job involves, what changes the price, and what to ask a pro.

What gutter guard installation is

Gutter guard installation fits screens, covers or inserts over gutters to keep leaves and debris out while letting water in. People call when gutters clog every season, when the roof sits under trees, or when cleaning is hard to do safely on a tall or steep home.

Signs you need it

  • Gutters that clog with leaves and pine needles more than once a season, even after cleaning
  • Overflow during heavy rain with debris packed in the trough and the downspouts
  • A roof under trees that drop seeds, needles or blossoms through much of the year
  • Standing water or sprouting plants growing in the trough
  • Gutters on a high or steep roof that you do not want to clean by ladder each season

What the pro does

  • Clean and inspect the gutters first, since guards cannot fix a sagging or leaking gutter
  • Confirm the gutter slope and repair any loose hangers or sections before the guards go on
  • Fit the guard type you chose, such as a screen, a reverse curve or a foam insert, to the gutter profile
  • Fasten the guard to the gutter lip or the hangers so wind and snow do not lift it, and trim it neatly at the ends and corners
  • Run a hose test to confirm water enters the gutter and reaches the downspout, and check that the guard does not hold water at the edge

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • Total length of gutter and the number of runs and corners
  • Guard type, such as mesh screen, reverse curve or foam insert, since each has different materials and fit needs
  • Gutter profile, and whether the guard fits that profile without modification
  • Condition of the gutters, since repairs or new hangers may be needed before the guards go on
  • Height and access, including two-story and steep homes that need lifts or fall protection
  • Removal of old guards or existing debris
  • Whether the downspouts or outlets need upgrading for the flow

What a written quote should spell out

  • Guard type, material and manufacturer, with the gutter profile it fits named
  • Length of guard for each run, and the corners and ends that are trimmed
  • Fastening method and how the guard attaches to the gutter lip or hangers
  • Pre-install cleaning and any gutter repair, listed as separate lines
  • Whether the warranty covers the material, the finish and the workmanship
  • Cleanup and removal of trimmings and debris from the install

Questions to ask before you hire

  • Which guard type do you recommend for my trees and my gutter profile, and why?
  • Will the guard reach the back of the gutter, or will debris still collect at the back edge?
  • How do you fasten the guard so that wind and snow do not lift it?
  • Do I still need to clean the gutters after the guards go on, and how often?
  • Will the guards affect the downspouts, and will you check the flow after the install?
  • What does the manufacturer warranty cover on the material, and what does it leave out?
  • Can you show me a finished install on a home with trees like mine?

Red flags

  • A guard pitched as a fix for sagging or leaking gutters, which it is not
  • Guards held only by clips with no fastening plan for wind or snow
  • A claim that no maintenance will ever be needed after installation
  • Adhesive or tape used in place of fasteners on the gutter
  • No hose test or flow check after the install

What you can do yourself

You can safely check the gutters from the ground, clear debris from any section you can reach without a ladder, and flush the system with a hose to see where water flows. Installing guards means working at the roof edge with sharp metal and long pieces, so leave the install to a pro. Call a pro once the gutters need repair or the install needs more than ground-level access.

Licenses and permits

Gutter guard installation is commonly offered by general exterior contractors, and rules vary by place. Check with your state and local licensing agency, and check contractor licensing if the install includes gutter or fascia repair.

Gutter guard installation questions

Do gutter guards keep out all debris?

No. Guards keep out most large debris, but fine grit and pine needles can still get through some designs. Ask the installer which debris your guard type handles well and which it does not.

Can gutter guards cause ice dams?

They can change how snow and ice behave at the roof edge, so the roof and attic ventilation matter. Ask the pro how the guard design handles snow and ice where you live.

Do gutter guards need cleaning?

Yes, on most designs. The surface of the guard can collect grit, and the gutter behind it still needs a check. Ask the pro how to clean the guard and how often.

Can I put guards on old gutters?

Only if the gutters are sound. Guards add weight and tension, so loose hangers, sagging sections and cracked joints must be fixed first.
