Composite Roofing Installation
Why Composite for a Northwest Roof?
Modern architectural composite shingles are a long way from the flat three-tab roofs of decades past — dimensional profiles, algae-resistant granules (which matter here; the black streaking on Northwest roofs is algae), and wind ratings that hold when they’re fastened to the manufacturer’s schedule. Lifespans run decades, warranties are strong, and repairs are straightforward because the material is everywhere.
A re-roof puts crews on a steep surface directly above your driveway, your landscaping and whoever is home that day, so fall protection, tarping and daily cleanup are planned before the first shingle comes off — magnetic sweeps for nails at the end of every shift, and the site left walkable overnight.
Shingle Manufacturers We Install
Our safety program has been recognized nationally by the NAHB, and our record with L&I is clean — no safety inspections, no license violations, no claims against our bond. You can check that yourself under contractor license SIDEPI*008N1. More on how we work safely.
How We Install It
Tear-off to the deck and a full deck inspection — the only honest moment to find rot, and in this climate there’s often some. Then underlayment appropriate to the slope, ice-and-water protection at eaves and valleys, flashing at every penetration and wall transition, and shingles fastened to the manufacturer’s nailing schedule. Wind damage on Northwest roofs almost always traces back to fastening shortcuts, not the wind.
If siding is part of the project, we sequence the two so each protects the other — kick-out flashing and wall transitions are where roofs and siding meet, and where separate contractors point fingers. One company, one schedule, no finger-pointing.
What Affects the Cost?
Roof size and pitch, how many layers come off, deck repair uncovered at tear-off, the shingle line you choose, and complexity — valleys, dormers, penetrations, and chimneys all add flashing work. We walk the roof and give you a real number, free, with no pressure attached.

What Affects the Cost of a Composite Roof
Two houses with the same roof area rarely price the same. What moves the number:
- What the tear-off finds.Deck rot is only visible once the old roof is off, so an honest number follows the inspection rather than a price list. We photograph what we find and price the repair before we carry on.
- Pitch and access.A steep roof slows every stage of the work and changes the fall protection required. Tight lots, tall gables and limited space for the dump trailer all show up in the labor.
- How many layers come off.One layer of old shingle is a different disposal cost from two or three, and plenty of Puget Sound houses have been roofed over at least once already.
- Penetrations and transitions.Vents, skylights, chimneys and roof-to-wall flashing are where the hours go, and where roofs fail. A simple gable costs less than a cut-up roof of the same square footage.
- Shingle line and warranty.Moving up a product line changes the material cost, and with most manufacturers it changes what the warranty covers once the system is installed complete.
Re-roofing a townhome row, condominium or low-rise commercial building? Composite still applies, but the phasing and scheduling are a different job — see commercial and multi-family composite roofing.
Composite Roofing Questions
How long does a composite roof last here?
Decades — the exact number depends on the shingle line, the installation, and the maintenance (mainly keeping moss and debris off). The installation is the variable you control most.
What about the black streaks I see on roofs everywhere?
Algae, feeding on moisture and granule fillers. Modern algae-resistant shingles largely prevent it.
Can you do the roof and siding together?
Yes, and it's often the smart sequence — the transitions between roof and wall are where leaks live, and one company detailing both sides of that joint is the fix.
What warranty comes with it?
The manufacturer's shingle warranty plus Side-Pro's 5-Year Workmanship Warranty* on the installation. *Restrictions and details apply.
How many layers can go on before a tear-off is required?
Washington allows a limited number of layers, but the more useful answer is that we tear off almost always — layering hides the deck, and the deck is exactly what needs inspecting. You cannot find rot through a second layer of shingles.
Do you handle gutters as part of the job?
Yes. Gutters, drip edge and the roof-to-wall transitions come off and go back as part of the scope. That junction is shared territory with your siding, which is why it is better done by one crew than two.
