When a leak in your roof just won't go away, there are several different things that could be causing it, ranging from your roof's insulation and ventilation to even your gutters. Addressing these issues and having your roof thoroughly inspected in case it needs to be completely replaced, will help prevent future water damage and stubborn leaks.
In instances where your roof's insulation is failing, it can allow enough heat from your home to transfer to the roof above. This in turn has the effect of creating an ice dam when there's snow and ice on your roof; the heat from below melts the snow and ice directly over it, but the ice below it holds it in place like a pool. When water is held up on your roof like that rather than being allowed to flow off, it can start to penetrate your roofing material even if there's nothing else wrong with your roof. Have your insulation inspected and replaced if necessary, as adequate roofing insulation is vital to its function.
Improper ventilation is another passive kind of problem that can cause leaks. When hot and cool air can't be vented through your attic space well enough, it can contribute to ice dams in a similar fashion by keeping hot air trapped inside. This can also cause other issues, like HVAC system inefficiency, but the biggest way it can cause trouble is by leading to leaks. When your roof is inspected, make sure this includes the ventilation system as well.
Clear Your Gutters
Clogged gutters primarily contribute to causing leaks by preventing water from flowing off your roof as it should, acting as another type of dam. Because gutters are usually on the roof's eaves, it's less common for clogged gutters to leak inside your house itself, but it's not impossible. Even if they don't cause leaks directly, they can contribute by weakening your roofing material as water and debris are held back on your roof. Gutters clogged with debris and water can also start to sag, which can start to damage your roof if too much weight is pulling on it. Your gutters, as well as your downspouts, should be cleaned at least once a year, and more often if you have trees growing near your roof.
Have Whole Roof Inspected and Replaced
If your roof is getting old, it may be nearing the end of its life, meaning that the only surefire way to stop recurring leaks is to have it replaced completely. When you decide to do this, it's still important to get a thorough inspection of your home to make sure that your attic's ventilation is good, that any water damage has been located and fixed, and that the underlying roof structure isn't in need of serious repair before your new roof can be put on.
