Choosing Between Gutter Repair and Full Gutter Replacement

Deciding Between Gutter Repair and Gutter Replacement

Once a gutter problem has been spotted, the next decision is whether to repair the existing system or replace it. A leaking joint or a short sagging run is usually a straightforward repair. An old, brittle system that leaks in several places, or gutters that cannot cope with the volume of water coming off the roof, is often better replaced. Making the right call saves money in both directions, because repeated repairs to a failing system add up, while replacing a sound system is money spent too early.

This article sets out how to weigh up gutter repair against gutter replacement for a house in Ireland. It covers the age and material of the system, the type and extent of the damage, the condition of the fascia boards, the size of the gutters and the options available when replacement is the better choice.

Start With the Age and Material of the System

The material and age of your gutters give a good first indication of how much life is left in them.

uPVC Gutters

Most Irish homes built or re-guttered in recent decades have uPVC gutters. They are light, affordable and resistant to rot. Over many years of sunlight and temperature changes, the plastic can become brittle and the rubber seals in the joints harden. A uPVC system that is twenty or more years old and leaking at several joints is often near the end of its useful life.

Cast Iron Gutters

Older and period homes may still have cast iron gutters. Cast iron lasts a very long time when painted regularly, but rust attacks joints and the inside of the gutter once the paint fails. Individual sections can be repaired or replaced, which is worth doing on period houses where the original look matters.

Aluminium Gutters

Aluminium systems, including seamless gutters formed on site, are strong and long-lasting. Problems usually come from impact damage or failed joints at corners and outlets, which are normally repairable.

Problems That Are Usually Repairable

Many gutter faults are local and can be fixed without replacing the system. Typical examples include:

• A single leaking joint where the seal has perished or the clip has moved
• A short section that has been cracked by a ladder or falling debris
• A run that has dropped because one or two brackets have failed
• Gutters that overflow because of a blockage in the gutter or downpipe
• A downpipe that has come loose from the wall or separated at a joint
• A stop end or outlet that has worked loose

These repairs involve cleaning out the gutter, fitting new seals or joint clips, replacing the damaged length, adding or replacing brackets and resetting the fall so water runs to the outlets. On a sound system, they restore it to full working order for a modest cost.

Signs That Replacement Makes More Sense

Replacement becomes the better option when the problems are spread across the system rather than in one place. Consider replacing the gutters when:

1. Leaks keep appearing at different joints, one after another
2. The plastic is brittle, discoloured or cracks when handled
3. Cast iron sections are rusted through in several places
4. The gutters overflow in heavy rain even when they are clean
5. The fascia boards behind need replacing anyway
6. The system has been altered and patched so often that it no longer runs true

Repairing an old system piece by piece can end up costing close to the price of a new one, without the benefit of new materials and a full guarantee.

Check the Fascia Boards First

The fascia board carries the gutter brackets, so its condition has a direct bearing on the decision. If the fascia is rotten, no repair to the gutter will last, because the brackets have nothing solid to hold. In that case, the fascias need replacing, and it usually makes sense to fit new gutters at the same time rather than taking down and rehanging the old ones. Our fascia and soffit page explains this work in more detail.

Gutter Size and Capacity

Irish rainfall can be intense, and short bursts of very heavy rain are becoming more common. Many older houses were fitted with small half-round gutters that cannot carry the water from a large roof slope in a downpour. Extensions, dormers and conservatories that drain onto the main roof add even more water.

If gutters overflow in heavy rain even when they are clean and correctly aligned, the system is undersized. Replacing it with a deeper or wider profile, or adding an extra downpipe, solves the problem in a way that no repair can.

Gutter Replacement Options

When replacement is the right choice, there are several systems to choose from. uPVC remains the most affordable and is available in half-round, square, ogee and deep-flow profiles in a range of colours. Aluminium gutters, including seamless systems, offer greater strength, longer life and fewer joints. Cast iron or cast aluminium suit period homes where appearance is a priority. A roofer can advise on the profile and size that suit your roof area and the style of the house.

A replacement normally includes removing the old gutters and downpipes, checking and repairing the fascias, fitting new brackets at the correct spacing, setting the fall to each outlet and connecting the downpipes to the existing drains. More information on the systems we fit is on our gutter repairs page.

What Affects the Cost

The cost of a gutter repair or replacement depends on the length of guttering, the number of downpipes and corners, the height of the building and the access needed. Single-storey extensions and bungalows are quicker to work on than two-storey houses, and scaffolding or a mobile tower adds to the cost on taller buildings. Replacing fascias and soffits at the same time adds to the materials but saves on labour and access compared with doing the jobs separately.

Downpipes and Drainage at Ground Level

Whether the gutters are repaired or replaced, the downpipes and the drains they feed should be checked at the same time. A new gutter system will still overflow if a downpipe is blocked, cracked or too small, and water that reaches the ground needs somewhere to go. Each downpipe should discharge into a gully or drain that is clear and in good condition. Where a downpipe simply ends above a path or flower bed, water soaks the base of the wall and can cause damp and damage to foundations. Clearing gullies and extending or redirecting downpipes is often a small job that makes a large difference to how well the whole system works.

Getting an Honest Assessment

The most reliable way to decide is to have the whole gutter system inspected from close up, rather than judging it from the ground. A roofer can check every joint, bracket and section, look at the fascias and confirm whether the gutters are large enough for the roof. A clear recommendation should explain which parts can be repaired, which need replacing and why.

Gutter repair is the right choice for local faults on a sound system, while replacement makes sense when problems are widespread, the material has aged or the gutters are too small for the roof. Checking the fascias and the capacity of the system first leads to a decision that lasts.
