Quick Answer
Asphalt roof installation covers the full system, from the deck and underlayment to the flashing, vents, and ridge cap.
It suits Clark County homes with aging, leaking, or worn roofs. Most projects take 1 to 3 days and depend on the roof’s size, repairs, and weather.

Complete Asphalt Roof Installation for Southwest Washington Homes
Complete asphalt roof installation matters for Southwest Washington homes because roofs stay wet here for months at a time. Rain blows in sideways during storms, moss creeps across shaded slopes, and needles can pile up in the valleys. Over time, that wear can develop as curled shingles, bare spots after granule loss, or a brown stain on the ceiling that returns after every patch.
Alfred’s Roofing helps you understand whether replacement makes sense and what needs to be repaired before new shingles go on. Each roofing plan accounts for the supporting decking, drainage details, and roof openings while matching the style you want. A straightforward scope gives you a clear basis for the work your home needs.
Find Out How Your Roof Is Doing
A quick roof inspection tells whether you need a new roof, a simple repair, or just routine maintenance.
What Goes Beneath and Around Your Asphalt Shingles
An asphalt shingle roof includes the full roofing system, from the supporting deck, protective underlayment, edge details, flashing, and attic ventilation. The deck is the wooden layer the shingles are nailed into, and underlayment is the protective sheet laid over it. Flashing directs water away from walls, chimneys, and other openings where water tends to collect most.
When your roof has been damaged way past repair, a full roof replacement usually makes more sense. The job includes removing old roofing and checking the deck for rot or soft patches. A new roof always starts with a solid, working deck. A clear scope and estimate help you decide whether decking repairs, flashing replacement, and ventilation changes are included or handled as additional work.
Asphalt shingle roofs also suit sloped roofs that meet the selected product’s requirements. Flat additions may need a different roof material. Gutter replacement, siding installation, and any other structural repairs are listed separately so you can understand what each job looks like, before moving forward with a decision.
Why Professional Asphalt Roofing Work Pays Off
Professional asphalt roof installation helps establish a steady foundation for a well-performing roof. It protects your investment from mistakes that often lead to loose shingles, leaks, and early repairs.
Consistent, Overlapping Shingles: Each shingle row sits at the required spacing. It keeps rain flowing down the roof instead of reaching exposed seams.
Secure Fastening: Proper nail placement and tight seal strips help shingles stay anchored and resist lifting during Southwest Washington’s wind.
Better Attic Moisture Control: Balanced intake and exhaust ventilation help release damp air from the attic, which helps limit mold and keeps shingles from aging early.
Supports Warranty Coverage: Many manufacturers only offer their strongest warranties when a certified or licensed contractor installs the full roofing system.
Protected Flashing and Roof Openings: New flashings installed around chimneys, skylights, valleys, and vents seal off the gaps where most roof leaks start.
Fewer Repair Surprises Later: A roof planned and installed right the first time reduces early water damage, premature repairs, and paying for a second roof too soon.
Reliable installation affects whether a roof reaches its full life or wears out early. No roof is maintenance-free, but careful installation helps it start with a stable, stronger foundation.

How We Complete Asphalt Roof Installation
Alfred’s Roofing handles each asphalt roof installation with proper deck preparation, protective layers, and fastening shingles following the manufacturer’s requirements. This sets up a steady foundation where your roof can work and perform reliably for years.
Tear-Off and Deck Inspection
For roof replacement projects, the crew starts with removing the old shingles and underlayment to expose the supporting wood. We walk through the deck, mark any soft or rotted sections, and replace these damaged sections before the new structure goes down. Further repairs found during this stage are carefully explained before actual work proceeds.
Ice and Water Shield and Underlayment
Metal drip edge goes along the eaves first. Then self-sticking ice and water shield is rolled along eaves and valleys, while synthetic underlayment covers the rest of the deck. This step protects your home from rain even before the shingles go on.
Fit Flashing and Ventilation Work
Counter flashing is installed in roof joints and openings where the roof meets a chimney, wall, or skylight, along with fresh pipe boots. The crew also checks the soffit vents for blockages and adds a ridge vent where the attic needs more airflow.
Shingle Application and Finishing Details
Starter strips line the edges of the roof, then shingles are installed from the lower roof upward. Installation carefully follows the manufacturer’s specified overlap and fastening pattern. Ridge caps and finishing details are completed for your newly installed roofing system.
Most roof installations are finished between 1 and 3 days. Projects may take longer depending on the roof’s size, material chosen, if the sections underneath require repair, and what the weather looks like.
Three-Tab, Architectural, or Designer: Compare Shingles for Your Home
Alfred’s Roofing installs three-tab, architectural, and luxury asphalt shingles in Southwest Washington. Choosing the right shingle comes down to your budget, how long you plan to stay, and how you want your home to look from the street.
| Shingle Type | Appearance | Estimated Cost | Best For | Estimated Lifespan |
|---|---|---|---|---|
| Three-Tab Asphalt Shingles | Flat, evenly spaced pattern | Costs less | Rentals, outbuildings, and homes with tight budgets | 15 to 20 years |
| Architectural Asphalt Shingles | Layered, dimensional profile | Generally midrange | Most homes; strong value per year | 20 to 25 years |
| Designer Asphalt Shingles | Detailed profiles resembling slate or wood shakes | Generally higher | Homes that want a slate or shake look | 25 to 30+ years |
In Clark County, architectural shingles are often the go-to choice as they offer a balance between cost and roof lifespan. We help you compare each option, their trade-offs, and which material suits your home and long-term priorities.
What Moves the Price of a New Asphalt Roof
The price of each asphalt roof installation changes with the selected materials, full tear-off, and repair or installation details your property needs. Most Portland-Vancouver homes with architectural shingles and a full tear-off land between $14,000 and $20,000.
Roof Size and Pitch: Larger roof size and pitch need more materials. Steep roof slopes need extra safety gear and more focused work.
Existing Layers: A second layer of old shingles adds tear-off time and disposal fees.
Deck Condition: Rotted or damaged plywood has to be replaced before the new layers go on.
Shingle Type: 3-tab, architectural, and designer shingles each carry a different price.
Roof Openings and Valleys: Each opening, including chimneys, skylights, and valleys, add flashing and careful hand-fitting.
Ventilation and Permits: Adding ridge vents and pulling local permits can shift the overall project cost.
Every roofing system requires tailored work and process. A clear estimate and timeline starts with a quick visit to measure your roof, check the condition, and put the number in writing.

Asphalt Roof Installation FAQs
How much does asphalt roof installation cost?
How long does asphalt roof installation take?
Can I stay home while my roof is replaced?
Can new shingles go over my existing roof?
Do I need a permit for a new roof in Clark County?
How much does asphalt roof installation cost?
Architectural shingle installation usually costs $7 to $9 per square foot in the Portland-Vancouver area, while designer shingles cost between $10 and $14 per square foot. Beyond the shingles, this price covers tear-off, new underlayment, flashing, labor, and cleanup. Extra layers, deck repairs, or a steep pitch push the project scope higher.
How long does asphalt roof installation take?
A straightforward asphalt roof installation often takes one to three working days. External factors like weather delays, time for pulling permits, material ordering and delivery, roof complexity, and unexpected repairs can prolong the schedule. Ask for a project-specific estimate and timeline before work starts.
Can I stay home while my roof is replaced?
Yes, you can stay home during an asphalt roof replacement, though roof removal and nailing can be loud. Plan for children, pets, and anyone remotely working from home. Also, consider entrances that need to be accessible, where vehicles will be parked, and areas around your property that need to be clear during work.
Can new shingles go over my existing roof?
Yes, new shingles can often go over an existing layer, but roof condition, local requirements, and manufacturer instructions determine if that is appropriate. Overlaying a new roof also leaves the supporting deck harder to inspect. A roof inspection helps identify areas of concern before you decide to keep the layers beneath.
Do I need a permit for a new roof in Clark County?
Not always; it depends on your address. Unincorporated Clark County requires a re-roofing permit for every property. The City of Vancouver exempts a first or second roof layer on one- and two-family homes when no sheathing or structural work is needed. Other cities set their own rules, and Alfred’s Roofing can handle the paperwork for you.
