Leak repair

Roof leak repair in Atlanta, traced to the real entry point

The stain is rarely under the hole. Water runs along the deck and rafters first, so we start in the attic and trace it back to where it gets in.

Quick answer

Roof leaks in Atlanta most often start at four places: cracked pipe boots, valleys, the flashing around skylights and dormers, and nails that have backed out. Because water travels before it drips, we trace each leak from the attic to the roof, fix the entry point rather than the stain, and check nearby spots that are wearing the same way.

The work

Why fixing the stain doesn't fix the leak

Water that gets past a shingle runs downhill along the underlayment or a rafter until it finds a seam to drip through. A stain in the middle of a bedroom ceiling can start at a pipe boot several feet upslope, and sealant smeared on the roof above the stain seldom stops anything.

Tracing takes a flashlight in the attic, a close look on the roof and sometimes a hose test, which is why we quote after we find it.

Pipe boot and vent flashing leaks

The rubber collar around each plumbing vent cracks in the sun long before the shingles wear out, and it is one of the most common roof leaks there is. Water runs down the pipe and drips from the ceiling near a bathroom or kitchen. We replace the boot, or fit a newer style with a replaceable collar, and reseal the shingles around it. Metal vent caps get the same check for rust and lifted flanges, since they leak the same way.

Valley leaks

Valleys carry the water from two slopes, so any weakness there shows up quickly. Debris dams, worn shingles in a closed-cut valley, or a nail placed too close to the center line all let water under. We clear the valley, lift the shingles to check the underlayment beneath, and replace the damaged section with new underlayment and shingles, or open metal flashing where the valley needs more capacity. Valleys under trees collect the most debris and need the most attention.

Skylight and dormer leaks

Anything that sticks up through the roof has to be flashed where it meets the shingles, and skylights and dormer walls are where that flashing is most often wrong. Leaks here usually show as stains at the corners of a skylight shaft or down a dormer wall. We check the step flashing along the sides, the head flashing at the top and the kick-out at the bottom, and replace the pieces that failed instead of adding another layer of sealant over the old one.

Nail-pop and exposed-fastener leaks

Nails can back out as the deck expands and contracts, lifting the shingle above them until it cracks or lets water run down the shank. Exposed nails in ridge caps, vents and flashing rust and leak the same way. We reset or replace popped nails, seal their heads, and replace any shingle that cracked around them. Several pops in one area often point to decking movement or poor ventilation, which we check from the attic before calling the job done.

Atlanta rain and the leaks it finds

Leaks are common in Atlanta because the city gets above-average rainfall, and back-to-back storms turn a small entry point into soaked decking faster than in drier places. The cause also decides who pays. A leak opened by wind or hail usually falls under a covered peril on a Georgia homeowner policy, while a boot that simply wore out with age does not, so the photos we give you note which it is.

Cost

What a leak repair costs depends on

Most leak repairs are small once the entry point is found; the price follows what failed and how far the water spread.

  • Entry point

    Boot, valley, flashing or nail.

  • Parts

    Boots, flashing, matching shingles.

  • Wet decking

    Soaked wood replaced under the repair.

  • Roof pitch

    Steep roofs need more rigging.

  • Tracing time

    Hard-to-find leaks may need a hose test.

  • More than one leak

    Nearby failures fixed together.
