Gresham gets hit hard by the weather, which is genuinely tough on roofs. Around 50 inches of rain falls here every year, with the bulk of it arriving between fall and spring. That steady moisture finds its way into aging shingles, worn flashing, and soft spots in the roof deck beneath. On top of that, summer temperatures can push into the 90s before dropping back to the 30s in winter, and those temperature changes cause roofing materials to expand and contract over and over across the years. Add in windstorms that funnel off the Columbia River Gorge and drive rain sideways against your home, and it becomes clear why roofs here wear out faster than the calendar alone would suggest. Moss is another constant issue. With well over 150 rainy days each year, moss takes hold quickly and quietly breaks down asphalt shingles from the surface inward.
A full roof replacement addresses all of that at once. New shingles, proper flashing, and corrected ventilation work together to protect your home the way it needs to be protected in this specific environment. Stalcup Roofing and Construction has worked on homes throughout Gresham long enough to know what conditions your roof is up against, from mid-century ranch homes with original roof decking to split-level properties where water management gets complicated. That local experience shapes every replacement project from the first inspection forward.
Knowing what to expect from start to finish makes a roof replacement easier to manage. This outlines how Stalcup Roofing and Construction handles the process.
Choosing the right material for your replacement comes down to how well it holds up against the specific conditions your roof faces here. Gresham's persistent rain, moss pressure, and Gorge-driven windstorms narrow the field quickly toward options built for durability and weather resistance.
| Material | Best For | Key Strength in Gresham |
|---|---|---|
| Asphalt Shingles (High-Performance) | Most residential roof pitches and budgets | Algae-resistant coatings and enhanced wind ratings address the two most common local failure points |
| Metal Standing Seam | Homeowners prioritizing longevity | Resists moss growth, sheds rain efficiently, and holds up well against strong winds over 40-plus years |
Both options are well-suited to the 6/12 pitches common on Gresham homes, and both can be installed with the secure nailing patterns required to meet regional wind standards. Your choice will depend on your budget, how long you plan to stay in the home, and how much maintenance you want to manage over time. During the open roof stage, we also inspect your roof decking closely since chronic dampness in this area frequently softens plywood beneath older roofs. Any part of the roof that no longer provides a solid base gets replaced before new material goes down, so your investment starts on a structurally sound foundation.
Before any new material goes down, existing moss is fully removed from the roof deck and framing, not just the surface shingles. Skipping this step leaves organic debris behind that accelerates granule loss on your new roof and shortens its lifespan well before it should need replacing.
Tear-offs regularly expose ventilation problems that were hidden under the old roof, and leaving them unaddressed causes heat and moisture to build up in your attic over time. Correcting airflow issues during replacement protects the new roof decking and shingles from the inside out, which matters a lot given how much humidity Gresham roofs deal with year after year.
Windstorms off the Columbia River Gorge can drive rain sideways with enough force to pull up shingles that were not fastened to meet regional wind standards. Every installation follows nailing patterns built specifically for those conditions, so your new roof holds firmly at every edge and field section rather than lifting under pressure.
New shingles alone do not stop leaks if the flashing around chimneys, vents, skylights, and roof edges is worn or improperly set. During replacement, all flashing is installed fresh and sealed correctly so water does not find its way in at the spots most vulnerable to Gresham's persistent rain and driving winds.
Gresham's long wet season and the wind pressure that comes with living near the Gorge take a steady toll on older roofs, and that wear rarely announces itself until water is already getting through. A full replacement gives your home a clean start with materials and installation details matched to what this area actually throws at a roof. Getting the work done during the drier months, typically late spring through early fall, also means fewer weather delays and better conditions for materials to cure and seal correctly.
