10 Steps to Rehab an Old Box Gutter

Old box gutter needing repair

Rehabilitating an old box gutter is a daunting task, but it can be done with the right tools and know-how. Box gutters are a type of gutter that is installed on top of a roof, and they are typically made of wood or metal. Over time, box gutters can become damaged or clogged, and they may need to be repaired or replaced, but rehabilitating the old box gutter is generally a more cost-effective option.

Before beginning the rehabilitation process, it is important to clean the gutter thoroughly. This will remove any dirt, debris, or leaves that may be clogging the gutter and make it easier to identify any damage. Once the gutter is clean, inspect it for any cracks, holes, or other damage. If there is any significant damage, it may be necessary to replace the entire gutter. However, if the damage is minor, it may be possible to repair it using a patching compound or sealant.

Once the gutter has been repaired, it is important to seal it to prevent water from leaking in. This can be done using a variety of materials, such as caulk, tar, or roofing cement. Once the gutter has been sealed, it is important to paint it to protect it from the elements. Painting the gutter will also help to improve its appearance and make it more resistant to damage.

Inspecting the Gutter for Damage

Before embarking on the rehabilitation process, it is imperative to conduct a thorough inspection of the gutter to assess the extent of damage and determine the appropriate course of action. This entails examining the gutter both internally and externally for any structural issues, leaks, or corrosion. Pay particular attention to the following key areas:

1. Visible Defects

Look for any obvious cracks, holes, or dents in the gutter, as these can compromise its functionality and lead to water infiltration.
Check for loose or missing fasteners that may have caused the gutter to sag or detach from the roof.
Examine the seams and joints of the gutter for any gaps or separation, which can result in leaks.

2. Structural Integrity

Use a ladder or scaffolding to safely access the gutter and inspect its stability.
Apply gentle pressure to different sections of the gutter to identify any areas that flex or sag excessively, indicating potential structural weakness.

3. Corrosion and Rust

Examine the gutter for any discoloration, pitting, or flaking, which may indicate corrosion.
Look for any buildup of rust on the surface of the gutter or its components, as this can weaken the material and lead to further damage.
Pay particular attention to the areas where dissimilar metals are joined, as galvanic corrosion can occur.

Type of Damage	Signs to Look For
Cracks and Holes	Visible openings in the gutter
Loose Fasteners	Missing or loose screws, bolts, or nails
Sagging	Gutter appears to be drooping or uneven
Corrosion	Discoloration, pitting, or flaking on the metal
Rust	Reddish-brown deposits on the surface

Cleaning the Gutter and Removing Debris

Once the old box gutter has been uncovered, it’s crucial to thoroughly clean it to remove any dirt, debris, and blockages. This process involves two steps:

Clearing Large Debris

Start by manually removing any large pieces of debris, such as leaves, twigs, or trash, from the gutter. Use a trowel or a gloved hand to scoop up and discard these materials. This initial step will make it easier to access and clean the smaller debris in the next step.

Removing Smaller Debris and Blockages

To remove smaller debris, such as dirt, silt, or moss, you can use a combination of methods. Here’s a detailed breakdown of each method:

Methods for Removing Smaller Debris and Blockages
Method	Description
Water Flushing	Using a hose with a high-pressure nozzle, flush water through the gutter to dislodge and wash away loose debris. Start from one end of the gutter and work your way towards the other end.
Vacuuming	Use a wet/dry vacuum cleaner with an appropriate attachment to suck up debris from the gutter. This is particularly effective for removing fine materials like dust and pollen.
Soft Brush Scrubbing	Gently scrub the gutter surface using a soft-bristled brush to loosen and dislodge any stubborn dirt or moss. Be careful not to damage the gutter material.

Reattaching Loose Sections

Loose sections of box gutters can be reattached using a variety of methods, depending on the extent of the damage. For small gaps, a sealant or adhesive can be used to fill the void. Larger gaps may require the use of screws or bolts to secure the loose section to the rest of the gutter.

To reattach a loose section with a sealant, first clean the surfaces of the gutter that will be in contact. Then, apply a bead of sealant to one of the surfaces and press the loose section into place. Smooth the sealant around the edges with a putty knife or your finger. Allow the sealant to cure completely before using the gutter.

To reattach a loose section with screws or bolts, first drill pilot holes through the loose section and into the rest of the gutter. Then, insert screws or bolts through the holes and tighten them securely. Be sure to use screws or bolts that are the correct size for the thickness of the gutter.

If the loose section is badly damaged, it may be necessary to replace it entirely.

Material	Advantages	Disadvantages
Sealant	Easy to apply	May not be strong enough for large gaps
Screws or bolts	Strong and durable	Requires drilling pilot holes
Replacement section	Most durable option	Requires cutting and fitting

Sealing Leaks and Gaps

Thoroughly clean the surface around the leaks using a wire brush or a pressure washer to remove dirt, debris, and old sealant.

2. Apply New Sealant

Select a polyurethane or silicone-based sealant specifically designed for outdoor use and gutter applications. Apply the sealant around the perimeter of each leak, ensuring a tight seal.

3. Securely Fasten Loose Joints

Identify any loose or disconnected joints in the box gutter. Tighten screws or bolts to secure them firmly. If necessary, replace damaged or missing fasteners with new ones.

4. Repair Cracks and Holes

For larger cracks or holes, a more comprehensive repair is required. Follow these steps for effective sealing:

Step	Action
a	Clean and dry the area thoroughly.
b	Apply a layer of fiberglass mesh over the crack or hole.
c	Cover the mesh with a generous amount of epoxy resin.
d	Allow the resin to cure completely before applying sealant over the repaired area.

Replacing Corroded Metal

If the metal on the box gutter has rusted through or become too thin, it will need to be replaced. To do this, follow these steps:

1. Remove the old metal

Using a pry bar, carefully pry up the old metal gutter. Use a hammer to help if needed.

2. Clean the surface

Once the old metal is removed, use a brush or power washer to clean the surface of the gutter. Remove any rust, dirt, or debris.

3. Apply a metal primer

Apply a metal primer to the surface of the gutter. This will help to protect the new metal from rusting.

4. Cut and fit the new metal

Measure and cut the new metal to fit the gutter. Use a metal shear or tin snips to cut the metal.

5. Attach the new metal

Attach the new metal to the gutter using roofing nails or screws. Make sure to use enough nails or screws to hold the metal securely in place. Here’s a detailed guide on how to attach the new metal:
– If using roofing nails, start by nailing the metal in the middle. Then, work your way out to the edges, nailing every 6-8 inches.
– If using screws, start by drilling pilot holes into the metal. Then, insert the screws and tighten them until the metal is secure.
– Once the metal is attached, use a caulking gun to apply a bead of caulk around the edges of the metal. This will help to seal out water and prevent leaks.

Installing Downspouts

Downspouts are crucial for channeling water from the gutter system to the ground or a designated drainage area. Here is a detailed guide to installing downspouts:

1. Mark the Gutter and Downspout Locations

Determine where you want to install downspouts and mark their locations on both the gutter and the fascia board.

2. Cut Gutters and Fascia

Using a utility knife or a hole saw, cut out a hole in the gutter that is the same size as the downspout outlet.

3. Attach the Downspout Outlet

Slide the downspout outlet into the hole in the gutter and secure it with screws. Ensure it is securely fastened to prevent leaks.

4. Install the Downspout

Connect the downspout to the outlet and secure it with screws or bolts. Ensure that the connections are tight and leak-proof.

5. Add Elbows and Extensions

Checking the Slope

Importance of Correct Slope

Proper sloping is crucial for water drainage efficiency. Inadequate slope can lead to water stagnation, causing rust, corrosion, and other damage to the gutter system, as well as contributing to roof leaks.

Measuring the Slope

To determine if the gutter has sufficient slope, use a spirit level or a slope gauge. Extend the level or gauge over multiple sections of the gutter, covering a span of at least 10 feet. A minimum slope of 1/16-inch per foot (1.6 mm per 30 cm) is recommended, although a steeper slope (e.g., 1/4-inch per foot or 6.4 mm per 30 cm) is preferable for optimal drainage.

Adjusting the Slope

If the gutter lacks adequate slope, several methods can be employed to adjust it:

Method	Procedure
Raising the Hangers	Adjust the position of the gutter hangers by raising them higher on the fascia, thereby increasing the slope.
Lowering the Downspout	Reposition the downspout lower on the gutter, creating a greater slope towards the downspout.
Installing Gutter Raisers	Attach gutter raisers, which are angled brackets, to the fascia under the gutter, lifting the gutter to a higher slope.
Re-Hanging the Gutter	Remove the existing gutter and re-hang it with new hangers at a more appropriate slope.

It’s important to note that adjusting the slope may require repositioning the downspouts, installing additional downspouts, or modifying the fascia to accommodate the new slope.
