Housing company gutters: do they carry water away from the building?

The job of gutters is to collect the water running off the roof and carry it away from the building in a controlled way. When a gutter is blocked, leaks at a joint, has a loose bracket, or a downpipe empties straight onto the foot of the wall, the water ends up on the facade or the plinth. Indoors, the problem may not show for years.

Gutters are part of a bigger system

A single downpour does not usually cause damage. But if water runs down the facade from the same spot or collects next to the plinth year after year, the moisture load on the structure increases.

Rainwater management includes not only gutters but also downpipes, roof drains, rainwater gullies and drains, and the slope of the ground next to the building. A clean gutter does not help if the water from the end of the downpipe runs towards the foundations.

Who is responsible for gutters?

The Limited Liability Housing Companies Act does not mention gutters specifically. The company is responsible for maintenance except where it is the shareholder’s responsibility, and its responsibilities include the structure and main systems (chapter 4, section 2). The exterior parts of the building and rainwater drainage are therefore, as a starting point, the company’s responsibility unless the articles of association say otherwise. Responsibilities in general are covered in the article on the housing company division of responsibilities.

Shareholders should not set about repairing or cleaning the company’s rainwater system on their own. They must, however, notify the company without delay of any defects that the company is responsible for repairing. If water repeatedly overflows the gutter or runs down the wall in heavy rain, it is worth reporting it to the property manager or the maintenance company.

What to check

The following are practical recommendations, not statutory inspection requirements. Gutters can be checked from the ground. People should go onto the roof only via safe access routes and with fall protection, and work at height is a job for a properly equipped professional.

Blockages

Leaves, pine needles and other debris collect in gutters, especially in autumn and on plots with lots of trees. A blockage slows the flow of water and makes it overflow. If the same blockage keeps recurring, a one-off clean is not enough: agree a cleaning interval with the maintenance company and find out whether something like a leaf guard would help.

Sagging and brackets

A gutter must not hang down, sag noticeably or come loose from its brackets. If the slope no longer directs water into the downpipe, the water stands or overflows at the wrong point. Water left standing in the gutter after rain points to a slope or blockage problem. A single observation does not yet tell you the cause, but a recurring one should be investigated.

Downpipes and discharge points

A gutter can look fine even when the downpipe is blocked, a joint is leaking or a section of pipe has come loose. The most important question is where the water ends up, and this is best seen during heavy rain. From a safe spot, look to see whether water is overflowing the gutters, running down the facade, leaking from a joint or collecting next to the building. Photograph what you see.

Facade and plinth

If water repeatedly runs down the facade from the same spot, keep an eye on the condition of joints and seals. Standing water next to the building is always worth noting. If water from a downpipe ends up at the foot of the plinth, it is worth investigating the situation as a whole, including the slope of the ground. Signs of moisture are covered in the article on moisture problems in a housing company.

All year round, with the focus on autumn

In autumn, leaves increase the risk of blockages and there is plenty of rain, so gutters, downpipes and rainwater gully grates should be cleaned before the frosts. Blockages and leaks get worse when they freeze. Ice should not be removed from the roof or gutters using risky DIY methods. Other autumn tasks are covered in the article on autumn maintenance in a housing company.

In spring, meltwater puts the system under strain, summer downpours reveal any lack of capacity, and in winter snow and ice bring problems of their own. When observations are recorded in the maintenance log (huoltokirja), you can see whether you are dealing with a one-off or a recurring fault.

Maintenance or replacement?

There is no single right time to replace gutters. In a system that works, cleaning, tightening the fixings or repairing joints is often enough. If there is widespread rust, leakage or deformation, replacement may be justified. Age alone is not a reason to replace, but it is not worth endlessly patching a system that keeps leaking. To support its decision, the board needs information on the system’s condition, how well it works and the repair options.

Questions for the board

• When were the gutters last cleaned, and has cleaning been agreed with the maintenance company?
• Has the system had leaks, blockages or loose brackets?
• Where is rainwater directed, and does it collect next to the building?
• Are there streaks on the facade from running water?
• Has the condition of the gutters been taken into account in the maintenance needs report?

Frequently asked questions

How often should gutters be cleaned?

There is no single right interval. It depends on the trees nearby, the shape of the roof and how quickly debris builds up in the gutters. On a plot with lots of trees, cleaning may be needed more than once a year.

Can a shareholder clean a gutter themselves?

Work that is the company’s responsibility should not be done without a procedure agreed with the company. Cleaning gutters also involves a risk of falling.

Can blocked gutters cause moisture problems?

A rainwater system that does not work can direct water onto the facade and next to the foundations and increase the moisture load on the structure. A single blockage does not mean moisture damage, but a recurring problem should be investigated.
