Solution For A Small Leak

Some roof leaks are tough to locate. Sometimes the water shows up at a ceiling spot distant from the leak. If your ceiling has a plastic vapor barrier between the drywall and the attic insulation, push the insulation aside and look for flow stains on the plastic. Often water runs to openings in the vapor barrier, such as at ceiling light fixtures.

If you can’t see any telltale flow marks, and since the stain is fairly small, look at the underside of the roof for ‘shiners.’ A shiner is a nail that missed the framing member, in this case when the carpenter nailed the roof sheathing to the rafters. Moisture that escapes into the cold attic from the rooms below often condenses on cold nails. Sometimes you can spot this if you climb up into your attic on a cold night. The nails will look white because they’re frosted. When the attic heats up a bit during the day, the frost melts and drips, then the nails frost up at night again and so on. The solution is to simply clip the nail with a side-cutting pliers.

When Are Roof Leaks Not Covered By Home Insurance

There are a few circumstances when roof leaks are not covered by home insurance. The most common is when the leak is caused by a gradual deterioration, poor maintenance, or improper installation. This could include things like worn-out shingles, cracked caulk, or loose flashing. Another circumstance when roof leaks might not be covered is if your policy has a separate deductible for wind and hail damage. This means that even if your policy covers roof leaks, you will still have to pay the deductible before insurance kicks in. Finally, some insurance providers exclude coverage for certain types of roofs, such as metal or flat roofs. Be sure to check with your insurance company to learn more about your roof leak repair coverage.

Roof Vents Without A Filter

Roof vents that are designed without filters can end up letting fine, wind-driven snow blow into your attic. This snow piles up, and while it remains cold outside you wont notice. However, when it begins to warm up, and the temperatures get above freezing, the snow is going to begin to melt. Now that moisture may start to drip and stain your ceiling.

The liquid eventually evaporates, sometimes leaving a permanent stain. Sometimes the water spots will disappear and may be gone for several years until the exact same conditions occur again.

Solution: Stop by the store. Hardware stores sell a commercial filter that will come in a roll. The filter is usually blue and about 1 thick. It can be cut with scissors and friction fit into the bottom of the vent, or if you can, around the upright portion of the vent. The filter blocks the snow but allows the air to flow freely.

Stains around vent show where water has been leaking in.

Common Roof Leaks: Damaged Vent Pipe Collars

Typically, vent pipe leaks occur at the collar surrounding the base of the vent pipe where it breaks through the surface of the roofing material. These collars consist of a metal base, generally made out of aluminum, and a rubber boot integrated into the top of the collar.

The collars job is to create a tight seal, keeping rainwater and debris from getting into your attic. Over time, through exposure to the sun and harsh weather, the rubber boot may wear out and deteriorate or split. Rusty and cracked vent pipe collars will allow the water to first pool around, then seep through the interior walls of your home causing great damage.

Deterioration of the underlying metal flashing and roof cement around vent pipes is also a common occurrence.

Bottom line: If the collar is cracked or damaged, it will need to be replaced.

Why Repair A Roof

A roof is one of the most important parts of a home, and it’s important to keep it in good condition, but factoring in the cost of labor and materials, it’s no secret that it can get pricey fast. If you’re not sure the investment is worth it, we’d encourage you to think about the future.

A roof protects your home from the elements, and if it’s in good condition, it can last for decades. However, without regular maintenance and minor roof repairs, your initial investment might not pay off the way you want it to. Over time, roofs will start to show signs of wear and tear, and if left unchecked, this can lead to serious interior damage. That’s why it’s important to repair a roof as soon as you notice any faults.
