What emergency roof repair involves, step by step
When water is running down a wall, the first job is stopping it, not selling a new roof. We tarp the damaged slope, clear debris out of valleys and gutters, and dry the attic before we talk numbers.
- A roof inspection starts at the roofline, looking for a failed pipe boot, a split valley, or chimney flashing pulling off the masonry.
- Emergency tarps go over the open section, lapped and anchored so wind uplift cannot peel them loose overnight.
- Saturated insulation and soft sheathing come out, because trapped moisture rots a roof deck faster than rain does.
- We lift the damaged field course with a pry bar and roofing shovel, then bag the debris into a dumpster.
- Replacement shingles go over synthetic underlayment, held by ring-shank nails set to the right depth for the deck.
- A starter course at the eave and staggered courses up the rake stop wind-driven rain from wicking under the laps.
- Every fastener from the nail gun and air compressor gets set flush, since an overdriven nail or screw tears the mat.
- We close with a sealant or caulk bead at each penetration and check exposure on the rooftop with a roofing square.
What a roofer inspects, and what failure looks like
Most leaks we get called to are not the shingle itself. They are a fastener, a seal, or a piece of flashing that failed quietly through two winters.
- Granule loss and curling on an asphalt shingle point to end-of-life wear rather than one puncture.
- Step flashing and counter-flashing at a dormer or parapet corrode, and water wicks behind the lap.
- Cracked mastic around a pipe flashing or vent boot lets water seep into the ceiling below.
- Soft plywood near a skylight or chimney means the substrate has decayed and needs replacement.
- A sagging gutter, a loose downspout, or rotted fascia pushes runoff back under the drip edge.
- An ice dam at the eave forms where ice-and-water shield was skipped or run short.
- A clogged ridge vent or a dead attic fan traps vapor, and mold shows on rafter tails by spring.
Materials and systems we replace
We match what is already up there when a patch is the right call. When it is not, we say so plainly and price the alternative.
- Three-tab shingle is the lighter economy option, while architectural shingle carries a heavier mat and a better wind rating.
- Wood shake and cedar shake need a different fastener pattern and more clearance than any asphalt product.
- Slate, clay tile, and concrete tile last for decades but crack on impact and demand careful walking.
- Metal panel, standing-seam panel, and corrugated panel shed water fast and live or die on sealant quality.
- TPO, EPDM, and PVC membrane cover the low-slope and flat roofing areas where shingles cannot go.
- Built-up roof and modified bitumen still top plenty of buildings here and can take a coating, an overlay, or a recover instead of a full tear-off.
- Felt and tar paper are the old standards, and synthetic underlayment with a vapor barrier is what we install now.
- Self-adhered and adhesive-backed membranes go down cold, with no torch near dry wood.
What is underneath, and why it decides the job
Pull the shingles and you see the frame. A soft truss or a joist that has moved tells us the leak ran longer than anyone thought.
- A sagged truss or rafter usually means water entered at a valley or dormer and soaked the framing for seasons.
- The ridge beam carries the peak, and when it settles the roofline shows it from the street.
- Purlins, battens, and counterbattens hold tile and metal panels, and a loose batten lets panels lift in wind.
- Roof deck panels, plywood or OSB, are the substrate, so a soft sheet comes out before anything goes back on.
- A peeling soffit or overhang points to blocked ventilation, not just tired paint.
- On a hip or gable, the verge and overhang take the worst weather and fail first.
Timelines and what actually drives cost
A tarp goes up the same day. A permanent fix usually takes one or two days once the deck is dry, and the roof estimate follows the inspection instead of a guess over the phone.
- Access drives labor, since a steep pitch, a mansard or gambrel section, or a canopy and awning over an entry means scaffold and a safety harness instead of a ladder.
- Deck condition drives material, so one sheet of plywood is a very different invoice than half the roof.
- Building code drives scope, since ice-and-water shield coverage at the eave is required, and a town inspection adds a day.
- A scupper or coping repair on a flat roof takes a different crew than a shingle patch.
