"Luke and his crew were great. They fit my job to replace the roof of the copala on my big barn and sided the entire barn within a few days. I'm so glad I called GCS, I wouldn't have gotten this done by any other company this fast and done as well."

- Laurie Crawford Bradley, 5-Star Google Review

Why are our roofing systems built specifically for Lewiston’s climate and long term performance?

Lewiston sits at the Snake and Clearwater rivers where canyon winds, hot summers, and valley fog work a roof hard. Freeze – thaw on shaded slopes and sudden gusts off the Lewiston Hill grade stress shingles and flashings.

That is why our roof replacement and preventative roof repairs are engineered for Lewiston. We use tight details, correct materials, and installation that follows manufacturer specifications.

Every layer matters on a Lewiston roof

We build the whole system so leaks do not start later. Solid decking and sheathing, ice and water shield at eaves and valleys, field synthetic underlayment, primed drip edge with starter strip, and metal or shingle valleys.

We seal step flashing and counter flashing, replace pipe boots, balance soffit ventilation with continuous ridge vents, and finish with reinforced ridge caps. Miss one layer and leaks follow – so we do not miss.

What does a proper roof replacement include in Lewiston – not just a shingle swap?

Our roof replacement starts with a full tear off to clean decking. We replace soft sheathing, correct fascia rot, and dry in the structure the same day.

We install synthetic underlayment in the field and place ice and water barrier at eaves, rakes, valleys, skylights, and chimneys. You get new drip edge, closed or open valleys with aluminum or steel valley metal, and high wind nailing patterns tuned for Bryden Canyon and 21st Street gusts.

Choose architectural asphalt shingles from Malarkey – Legacy, Vista, or Highlander – for value and warranty strength. Step up to standing seam metal roofing in 24 or 26 gauge with Kynar finish for heat reflectivity and long service life.

  • Deck repairs and plywood or OSB sheathing replacement as needed
  • Ice dam defense on north facing eaves and deep valleys on Normal Hill
  • New step flashing and counter flashing at walls, chimneys, and dormers
  • Balanced attic airflow to cut condensation and summer heat
  • Clean jobsite with tarp protection, magnet sweep, and haul away

Repair or replace – how do you make the call?

Roof repairs make sense when leaks are isolated, shingles are largely intact, and the system is under about 15 years. A full roof replacement is smarter when you see bald shingle areas, curled tabs, wind lifted edges on the Orchards side, nail pops, soft decking, or repeat leaks after past fixes.

  • Replace now if stains are spreading inside or granules fill gutters and downspouts.
  • Roof repairs now – plan later if damage is limited to one slope or one valley.
  • Monitor if the field is sound but flashings and vents need reseal and maintenance.

Common Lewiston roof damage – what we repair fast

  • Torn shingles, missing or fractured ridge caps, and lifted starter courses
  • Cracked pipe boots, failed sealant, exposed fasteners, and nail pops
  • Leaking skylight curbs, fogged lenses, and brittle gaskets
  • Rusting or undersized valley metal, clogged gutters, and weak diverters
  • Loose step flashing at siding transitions and dead wall leaks that need crickets
  • Ventilation problems – blocked baffles, short soffit intake, overheated attics
  • Metal roof service – seam tightening, fastener swaps, and snow guard installs

Our Lewiston crew prioritizes same week roof repairs with photo documentation for insurance. You get a clear written scope and a repair plan that fits your roof.

How do we build for heat, wind, and freeze – thaw in Lewiston?

We design for canyon weather and summer heat. Extended eave membrane, watertight valleys, high wind fastening on ridges, and correctly sized drip edge with kick out flashing keep water where it belongs.

On metal roofs we add snow guards above walkways and steps and use panel gauges, clip systems, and sealants that handle wind and thermal movement from the river corridor.

After a storm, what 5 minute self check should you do?

  1. Walk the perimeter and look for missing shingles, torn ridge, or loose flashing.
  2. Check ceilings and closets for fresh water spots after a hard rain or thaw.
  3. Scan chimneys and vents for exposed nails or cracked sealant.
  4. Open a downspout – heavy granules mean aging shingles and time to discuss roof replacement.
  5. Sight the ridge line for dips or sags that point to sheathing issues.

See something off. Book a same week inspection. We will map issues, propose roof repairs or a full roof replacement, and give you a step by step plan.

What timeline and jobsite protection should you expect?

  • Day 0 – On site roof inspection, moisture readings, drone photos, and a line item estimate with materials, labor, and accessories by slope.
  • Day 1 to 2 – Tear off, sheathing fixes, full dry in by end of day one, then shingle or metal install. Most Lewiston roof replacement projects finish in one to two days. Complex roofs can take a third.
  • Daily – Landscape protection, driveway access management, magnet sweep, and end of day cleanup.
  • Wrap up – Final walkthrough, warranty registration, a photo set for your records, and a maintenance checklist.

Which roofing material is best for your part of Lewiston?

Architectural asphalt shingles look great in Downtown and Normal Hill and carry strong wind ratings. Upgrade to impact resistant Malarkey where trees overhang or debris is common.

For the Lewiston Orchards and hillsides above the river, many owners choose standing seam metal roofing for heat reflectivity, snow shedding, and long service life. We size snow brakes where slides could hit decks or entries and tune gutter capacity for cloudbursts along Snake River Avenue.

How do ventilation and insulation prevent leaks and ice dams?

Warm attic air can melt the snow layer from below and create leaks. We verify soffit intake, ridge exhaust, and open baffles so airflow stays balanced.

Air sealing around can lights, bath fans, and chases plus correct insulation depth supports the system. During roof replacement we restore ventilation pathways and add insulated vent chutes at tight eaves in older Lewiston homes.

Will a new roof help with efficiency, resale value, and insurance?

Yes. A code tight roof replacement with cool roof shingles or reflective metal, sealed penetrations, and balanced ventilation lowers attic temperatures and reduces energy waste.

Buyers value a transferable manufacturer warranty and clean documentation. Appraisers and insurers like the photo record and itemized scope.

Permits, HOAs, historic details, and warranty registration

We handle permits and follow manufacturer specifications so warranties stay intact. Dormers, brick chimneys, and aging skylights are addressed up front to avoid mid project surprises.

After completion we register warranties and deliver your maintenance plan. You get a simple checklist tailored to your property.

What about gutters, fascia, and skylights during roof replacement?

Roofing touches everything at the eaves. We check gutter slope, outlet size, and downspout placement and repair or replace fascia as needed.

We recommend new skylights if seals are brittle or lenses are crazed. For metal roofs we spec compatible snow management so gutters are not torn by sliding sheets.

What seasonal timing works best in Lewiston?

We perform roof replacement and targeted roof repairs year round as weather allows. Spring and early summer give warm and dry days for asphalt adhesion.

Late summer into fall is excellent for both asphalt and metal. Winter focuses on emergency leak repair, ice dam removal, and safe partial reroofs. No matter the season, we dry in the same day we tear off.

What will you see on your estimate – and why does it matter?

Transparency wins. Your quote itemizes roofing materials by brand, profile, and color, underlayment type, ice and water coverage, flashing and ventilation upgrades, and decking allowances by square.

We list labor, tear off, disposal, magnet sweep, permit fees when applicable, and optional add ons like gutters and skylights. Clear scope makes insurance, resale, and long term maintenance simple.
