Roof leak repair in Maple Grove

Where Maple Grove roofs actually leak

Water almost never comes through the middle of a shingle field. It comes in where something interrupts the shingles, or where ice has pushed it uphill. After enough attics in Hennepin County, the list is short.

Ice dam damage at the eaves. The most common winter call. Water backed up behind an ice ridge gets under the first few courses and stains the ceiling near an exterior wall. If the roof has ice-and-water membrane to code, the damage is usually a few lifted shingles and wet insulation. If it's a 1980s roof with none, the decking and fascia at the eave may be rotted. Ice dam roof repair Maple Grove homeowners pay for runs $400–$1,500 for the roof edge itself; the ice dam page covers the attic side.

Pipe boots. The rubber collar on every plumbing vent cracks after 10–15 years of Minnesota freeze-thaw and summer UV. The stain lands near a bathroom or the kitchen. This is the most common roof leak repair Maple Grove MN homeowners call about between April and October, and it costs $250–$450 with a new boot and the shingles around it.

Chimney flashing. Brick chimneys on the 1980s two-stories around Fish Lake and along Zachary Lane were often flashed with one strip of aluminum caulked to the brick. When the caulk lets go, water runs behind it. Real chimney flashing repair Maple Grove roofs need is step flashing woven into the shingles with counter-flashing let into the mortar joint, plus a cricket behind chimneys wider than 30 inches, and it runs $600–$1,500.

Valleys. Two planes meeting carry more water — and more sliding snow — than anywhere else. On a 25-year-old roof the shingles there are worn thin. A valley re-lay with membrane underneath is $500–$1,200.

Skylights. Almost always the flashing kit, not the glass. Skylight leak repair Maple Grove homeowners book is $400–$900 for a new kit; a failed unit is $1,200–$2,500 replaced.

Wind damage. Lifted, creased or missing shingles on the slope that faced the storm. Shingle roof repair Maple Grove crews do after a straight-line wind event is $300–$800 for a few square feet; if a whole slope is creased, that's a storm claim.

Wall flashing at dormers and additions. Common on homes that added a room over the garage or a three-season porch off the back.

How we find the leak

1. We start in the attic with a flashlight, looking for the water trail on the underside of the decking and for frost on the nails, which tells us moisture is coming from inside the house, not the roof.
2. We walk the roof above that spot and check every penetration and flashing within about six feet.
3. If it isn't obvious, we run a hose on sections of the roof in sequence while someone watches from the attic. Thirty minutes, finds almost everything.
4. You get photos and a written price.

One thing we check every time: whether the "leak" is condensation. A bath fan venting into the attic or an unsealed attic hatch puts a lot of moisture up there over a Minnesota winter, and it drips in March exactly like a leak. Roof ventilation Maple Grove attics lack is a repair problem, not a shingle problem.

Repair or replace?

Most roof repair Maple Grove MN homeowners need is one or two spots on a roof with years left, and that's when we repair. We say so when it isn't: granule loss across the whole roof, two layers already up there, soft decking in more than one place, or hail bruising on every slope. Then a repair buys you a season and a replacement conversation anyway. The roof replacement page walks through it, and our guide on repair versus replacement has the numbers.

Emergency repairs

Emergency roof repair Maple Grove wide is triaged by water coming in, not by who called first. Winter emergencies are usually ice dams, and we steam them. Summer emergencies are wind damage and tree limbs — dead ash from the emerald ash borer are coming down across Hennepin County — and we tarp first ($300–$700) and repair once it's dry.

Gutters, decking and the edge of the roof

Gutter and roof repair Maple Grove homeowners book tend to go together, because a gutter that has iced over for five winters has usually pulled the fascia loose and rotted the first course of decking behind it. We replace decking at $90–$150 per sheet, rebuild fascia, and re-hang the gutter section so the fix holds. If you have moisture in the attic without an obvious source, read our guide on finding a roof leak from inside the house first.
