Roof Leak Repair in Indianapolis, IN

The most common causes of roof leaks

Flashing failures

Flashing is thin metal that seals the intersections of the roof: around chimneys, skylights, walls, dormers and in valleys. It corrodes, pulls away from masonry, cracks at the sealant or was never installed correctly. Flashing failures cause more leaks than almost any other roof problem, especially in older homes with multiple rooflines.

Cracked pipe boots and vent seals

Rubber collars around plumbing vent pipes crack in the sun. Even a hairline crack lets water run down the pipe into the attic and ceiling. Replacing a boot is quick and inexpensive when it is caught early.

Missing, cracked or lifted shingles

Wind and hail break the seal on shingles and create gaps. A missing shingle exposes the underlayment, which is not meant to be the only line of defense for long. We replace damaged shingles and check the surrounding area for related damage.

Exposed or backed-out nails

Nails that work loose and push up through shingles can create tiny openings that leak slowly. They show up as small stains in specific spots and often appear after a winter of freeze-thaw cycles.

Valleys and debris buildup

Valleys carry large volumes of water. Leaves, sticks and shingle granules can dam the flow, forcing water sideways under the shingles. We clear and, if needed, rebuild the valley.

Ice dams

In Indianapolis winters, heat leaking into the attic melts snow on the roof, and the water refreezes at the cold eaves. The ice ridge blocks drainage and water can back up under the shingles. Ice dam leaks are common after freeze and thaw cycles and often point to ventilation or insulation problems.

Skylights and chimneys

Skylights and chimneys have many joints, seals and flashing pieces. Old gaskets, cracked caulk and rusted flashing let water in. Sometimes what looks like a skylight leak is actually condensation, so a proper diagnosis matters.

An aging roof

When shingles are brittle, worn and shedding granules across the roof, leaks can appear in many places. Repairs buy time, but a roof like that is usually better served by replacement. See roof replacement in Indianapolis for the decision process.

How we find the source of your roof leak

Finding a leak is a process of elimination. We start inside, in the attic, looking for the wet decking, water trails and daylight, and we measure the position of the damage relative to chimneys, vents and walls. Then we go onto the roof and inspect the corresponding area closely, working uphill from the stain because water travels down along surfaces. We check flashing, penetrations, shingles and valleys.

When the source is not obvious, we use controlled water testing: with one person inside and one outside, we apply water to sections of the roof one at a time, starting at the lowest area and working up, until the leak appears. It is slower than guessing, but it avoids the common mistake of repairing the wrong spot. We document the source with photos so you can see exactly what failed.

What happens if a roof leak is ignored

A small, slow leak can cause damage out of proportion to its size. Wet insulation loses its insulating value and can hold moisture against the framing. Drywall stains, sags and eventually fails. Wood can rot, and mold can begin to grow in a damp attic or wall cavity within days to weeks under the right conditions. Electrical systems can be affected. Meanwhile, the original leak usually gets bigger. What might have been a few hundred dollars for a pipe boot can become a repair involving decking, insulation, ceilings and mold remediation.

If you suspect mold, do not disturb it, and consider contacting a qualified remediation specialist. We can repair the roof, but we are not a mold remediation company, and we will tell you when to bring one in.

Will insurance cover a roof leak?

It depends on the cause. Leaks caused by a sudden event, such as wind or hail damage, may be covered under a homeowners policy. Leaks caused by wear and tear, lack of maintenance or long-term deterioration usually are not. The Indiana Department of Insurance advises filing as soon as possible, photographing the damage before making temporary repairs, keeping all receipts and not making permanent repairs before the insurer inspects.

Roof leak or condensation? How to tell the difference

Not every ceiling stain comes from the roof. In cold weather, warm moist air from bathrooms, kitchens and laundry can rise into the attic and condense on cold roof decking and nails. This can look like a leak: frost on the nail tips in the morning, damp insulation, drips when the frost melts. The cause is air and moisture, not a hole in the roof, and the fix is better air sealing, bathroom fans that vent outdoors and proper ventilation.

Clues that point to a true roof leak include stains that appear or grow after rain or snowmelt, drips that are concentrated near a chimney, skylight, vent or wall, and water that follows the same path every time. Clues that point toward condensation include frost on the underside of the roof deck in winter, dampness across large areas rather than one spot and symptoms that appear on cold, dry days. Plumbing leaks, such as a failed supply line or an air conditioner drain, can also cause ceiling stains. If you are not sure, we can look at the roof and attic and tell you what we see, and we will say if the roof is not the cause.
