Roof Replacement and Repair

A roof keeps water out of everything underneath it, and most roof problems are water problems long before they are visible ones. Whether you need a leak traced and repaired or a full replacement, we look at the whole roof before we price any of it.

Signs your roof needs attention

Roofs fail gradually. These are the signs worth acting on before water reaches the ceiling:

Missing, cracked, or curling shingles

Damaged shingles expose the layers underneath to the weather.

Granules in the gutters

Shingles shed their protective granules as they age. A lot of it in the gutters means the surface is wearing out.

Stains on ceilings or in the attic

Water marks mean water is already getting in somewhere above.

Lifted or rusted flashing

Flashing that has pulled away from a wall or chimney leaves a gap at exactly the point water collects.

Sagging areas

A dip in the roof line can point to damaged decking or framing underneath.

Roofing, step by step

Every job follows the same sequence. You are told which stage you are at and what happens next.

  1. Inspection from the roof, not just the ground

    We check the surface, the flashing at walls, valleys, vents, and the chimney, the gutters, and the attic side where we can get to it. Most leaks start at a joint rather than in the middle of a slope.

  2. Written scope

    You get an itemized estimate that separates what needs doing now from what can wait, and says plainly whether repair or replacement is the honest answer.

  3. Tear-off and deck check

    On a replacement, the old roofing comes off down to the deck so we can see its condition. Soft or damaged decking is replaced before anything new goes on.

  4. Underlayment, flashing, and roofing

    Underlayment and ice and water protection go down first, flashing is reset at every wall, valley, and penetration, and then the new roof is installed.

  5. Cleanup

    Debris is cleared from the roof, the gutters, and the grounds at the end of every day.

Frequently asked

Do I need a new roof or just a repair?

It depends on the age of the roof and whether the problem is local or widespread. A single leak at a flashing or a few damaged shingles is a repair. Curling, cracking, or granule loss across the whole surface usually means the roof is at the end of its life. We tell you which one we see.

Where do most roof leaks start?

At the joints: flashing around chimneys, walls, and vents, and in the valleys where two slopes meet. The stain inside is often some distance from where the water actually gets in, which is why we trace it from the roof side.

Can you repair the flashing around my chimney?

Yes. Because we do chimney masonry as well as roofing, we can repair the brick and reset the flashing in the same job, rather than you coordinating two trades at the one joint where they meet.
