We’ve been climbing roofs in Des Moines since 2016. We know the mid-century ranches along South 216th Street, the split-levels up from the marina, and the steeper lots west of Marine View Drive where the wind off Puget Sound hits hardest. That local knowledge matters when we’re specifying materials that have to survive a quasi-coastal environment, not just standard Pacific Northwest drizzle.

Our technicians are background-checked, uniformed, and trained to spot the salt-air failure patterns that surprise newcomers to the bluffs - the white oxide on aluminum flashing, the accelerated corrosion on ridge caps, the moss that takes hold on north faces within a single damp season.

Our Roof Replacement & Installation Services in Des Moines
Full Roof Replacement
A full roof replacement in Des Moines means more than stripping old shingles. On the bluff homes west of Marine View Drive, we routinely find corroded flashing, compromised underlayment, and sometimes legacy cedar shake remnants hidden under torch-down overlays near the marina. We strip to deck, inspect for salt-air damage, and specify materials rated for coastal-equivalent exposure. A typical Des Moines full replacement runs $14,000-$28,000 depending on pitch, access, and whether we’re dealing with multiple layers or structural repair.
New Construction Roofing
For new builds in Des Moines, we coordinate with framers and general contractors to specify systems that account for the marine microclimate from day one. That means proper ice-and-water shield placement, stainless or copper flashing in high-exposure zones, and ventilation designed to move moist air out before it condenses in our persistent low-angle overcast. We’ve roofed custom homes above the Sound and tract builds throughout the 98198 zip code.
Asphalt Shingles
Asphalt shingles remain the most common choice in Des Moines’s mid-century housing stock, and for good reason - when specified correctly, they perform well and offer strong value. We install GAF Timberline, CertainTeed Landmark, and Owens Corning Duration lines, all with modified specifications for the salt-air environment. Standard warranties don’t always account for quasi-coastal corrosion, so we specify upgraded flashings and document the installation for manufacturer coastal-rider eligibility where available. Most Des Moines asphalt re-roofs run $12,500-$19,500.
Metal Roofing
Metal roofing is gaining ground in Des Moines, especially on homes where homeowners are tired of replacing flashings every decade. We install standing-seam and exposed-fastener systems in aluminum, steel, and copper, with particular attention to fastener selection - standard steel fasteners will bleed rust in the salt air within 5-7 years. We use marine-grade fasteners and proper isolation to prevent galvanic reaction. A metal roof on a Des Moines home typically runs $22,000-$38,000 but carries a 40-70 year service life.
Flat Roofing
Flat and low-slope roofs in Des Moines - common on additions, carports, and mid-century modern designs - demand particular care. The persistent dampness on north- and west-facing planes means standard torch-down or modified bitumen can trap moisture if not properly vented or if drains clog with moss debris. We install TPO, PVC, and premium modified bitumen systems with proper slope correction and drainage specification. Des Moines flat roof replacements typically range $8,500-$16,000.
Tile Roofing
Tile roofing appears less frequently in Des Moines’s core housing stock but suits the steeper waterfront lots and custom builds where weight-bearing capacity allows. We install clay and concrete tile from Boral and other manufacturers, with upgraded underlayment specified for the marine environment. The upfront investment runs higher - typically $28,000-$45,000 - but the lifespan and wind resistance reward homeowners who plan to stay.

Trusted Brands We Service in Des Moines
We are authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - seven manufacturer lines, properly specified, no substitutions. For Des Moines homeowners, that means we can match existing shingle profiles on mid-century ranches, source coastal-rated underlayment without special-order delays, and honor full manufacturer warranties because our installation meets their specifications. We keep common IKO and Atlas shingle colors stocked for the 98198 area, so matching and repairs move fast. When you need a roof that holds up to salt air, the material matters as much as the crew - and we don’t cut corners on either.
Common Roof Replacement & Installation Problems We See in Des Moines Homes
- Accelerated flashing corrosion. Aluminum step flashing on chimneys and skylights shows pitting and white oxide corrosion within 8-10 years on Des Moines’s west-facing bluffs - a failure mode rarely seen just miles inland in Federal Way or Renton. We replace with stainless steel or copper in high-exposure zones.
- Moss and lichen infiltration. The persistent dampness on north- and west-facing roof planes keeps shingles moist for months, allowing moss to lift tabs and trap water within a single season. Annual maintenance is essential, not optional, in this microclimate.
- Hidden legacy cedar shake. Older homes near the marina and on bluff lots often have cedar shake remnants under torch-down or composition overlays. We strip to deck and inspect, because covering compromised wood guarantees future failure.
- Garage door hardware seized by salt air. The same southwest wind that attacks roofs corrodes garage door springs, hinges, and rollers 2-3 years faster than inland. During roof replacement on waterfront homes, we coordinate hardware upgrades - galvanized or coated springs, stainless fasteners, nylon rollers - so the whole exterior envelope matches the environment.

| Service | Typical Range in Des Moines | Notes |
|---|---|---|

What moves the number: roof pitch (steeper = more labor), access difficulty (bluff lots with limited staging), layers to remove, and whether we’re replacing corroded flashing systems with upgraded stainless or copper. The salt-air environment means we rarely recommend minimum-spec installations - the savings evaporate in repair costs.

FAQs - Roof Replacement & Installation in Des Moines
The salt-laden southwest wind off Puget Sound accelerates galvanic corrosion on aluminum, causing pitting and white oxide within 8-10 years on west-facing bluff homes. Standard inland warranties don’t account for this quasi-coastal exposure. We specify stainless steel or copper flashing in high-salt zones, and we document the upgrade for your records. Call (866) 850-9676 for an inspection - estimates are free.
In Des Moines’s marine microclimate, inspect north- and west-facing planes at least twice yearly - spring and fall - because persistent dampness allows moss to establish within months, not years. Catching it early prevents lifted shingles and water intrusion. Our $89 Seasonal Tune-Up includes moss treatment, gutter clearing, and a photo-documented condition report. Call (866) 850-9676 to schedule.
Most standard manufacturer warranties exclude accelerated corrosion from salt-air or coastal exposure unless you have a coastal-rider endorsement and used specified materials. We specify coastal-rated systems where available and document installation to manufacturer standards so your coverage holds. Ask us about warranty specifics when we quote - we’ll show you the paperwork before you sign. Call (866) 850-9676.
On bluff homes in Des Moines, we recommend coated or galvanized torsion springs, stainless steel hinges and fasteners, and nylon rollers to resist the salt spray that seizes standard hardware in 2-3 years. During a full roof replacement, we coordinate these upgrades so your exterior envelope matches the environment. The field vignette: on a mid-century ranch near Marine View Drive, we replaced a failing composition shingle roof where the original aluminum step flashing around the chimney had corroded so badly it had to be cut out entirely. We used GAF Timberline shingles with stainless steel step flashing and coated coils to withstand the salt air, and installed nylon rollers on the garage door to prevent the hinge corrosion that had seized the previous door. Call (866) 850-9676 to discuss coordinated upgrades.
Standing-seam metal roofing with marine-grade fasteners and proper isolation typically delivers the longest service life on Des Moines’s most exposed bluff lots - 40-70 years with proper maintenance. Premium asphalt shingles with upgraded underlayment and stainless flashing are a strong second choice at lower upfront cost. We assess your specific exposure, pitch, and budget to recommend the right system. Call (866) 850-9676 for a free on-site evaluation.
