My name’s Scott Archer. I started tearing off roofs in 1990 as a laborer for Jorve Corporation up in Seattle, earned my journeyman’s card in 1996 in flat roofing — torchdown, TPO, PVC membranes — and I’ve held a general contractor’s license in both Oregon and Washington since 2016. Topline Construction, DBA Top Line Roofing Contractors, is the legal name on the license. I still walk and inspect every roof my crew puts on. That’s not a marketing line — it’s how I’ve run this business for over 30 years.

If you’re on this page, something’s probably gone wrong up there: a leak that keeps coming back, shingles curling or missing after the last windstorm, moss that’s worked its way under the mat, or a roof that’s simply reached the end of its life. Portland’s wet season is not gentle on a roof that’s past its prime, and putting off a replacement usually turns a roofing job into a roofing-plus-drywall-plus-insulation job. Let’s talk about what a real roof replacement involves here, and how to know when it’s actually time.

We handle roof replacements across the whole Portland metro, from Tigard to Gresham to Hillsboro, so whatever part of town you’re in, we already know how the local weather and tree cover treat a roof out there.

How do I know if I need a full roof replacement instead of a repair?

If the damage is isolated — one bad flashing detail, a handful of cracked shingles, a vent boot that dried out — a roof repair is the right call and the cheaper one. Full replacement makes sense when the roof is 20+ years old on a standard architectural shingle, when leaks are showing up in more than one area, when you can see daylight or soft spots in the decking from the attic, or when a previous owner or contractor patched over problems instead of fixing them. I’ll tell you straight during the inspection which one you actually need — I don’t sell replacements to homeowners who only need a repair.

What does a Top Line roof replacement in Portland actually include?

A full tear-off down to the decking, inspection and repair of any rotted or soft sheathing we find underneath (this is where a lot of contractors cut corners — we don’t), new synthetic underlayment rated for our climate, ice-and-water shield at the eaves and valleys, new flashing at every chimney, wall, and roof-to-roof transition, and then the new roofing material installed to manufacturer spec so the warranty actually holds up. We haul away and dispose of the old material — you’re not left with a dumpster of shingles in the driveway for two weeks.

How long does a roof replacement actually take?

For most Portland homes, one to three days once we’re on the roof, weather permitting. Tear-off and decking repair usually happens the first day, underlayment and flashing detail work the same day or into day two, and the new roofing material goes on last. Rain can push the schedule — we’re not going to install a roof in a downpour and risk trapping moisture under it, and I’d rather delay a day than warranty a roof I know wasn’t installed right.

What roofing materials hold up best in Portland’s climate?

Architectural asphalt shingles are still the most common choice here, and for good reason — they handle our rain-heavy, moderate-temperature climate well and come with strong manufacturer warranties from brands like GAF and CertainTeed. If you’re dealing with heavy moss growth from tree cover, or want a longer-term material, metal roofing is worth a look — it sheds moss and debris better and can outlast a shingle roof by decades. I’ll walk you through the tradeoffs based on your specific roof and how much shade your property gets.

Do I need a permit for a roof replacement in Portland?

Yes, in almost every case — the City of Portland and most surrounding jurisdictions require a permit for a full roof replacement, especially where decking or structural repair is involved. We pull the permit as part of the job so you’re not the one navigating that process, and it protects you if you ever sell the home and a buyer’s inspector asks for proof the work was permitted and done to code.

What does a roof replacement cost in Portland?

It depends on the size of the roof, the pitch, how much decking repair is needed once we’re into it, and the material you choose. I’m not going to throw out a number here that doesn’t mean anything for your specific house — for an honest, itemized estimate, request a free inspection and I’ll walk the roof myself and give you real numbers, not a range pulled from a national average.

Will a new roof actually increase my home’s value?

A roof in bad shape is one of the first things that kills a sale or gets flagged in an inspection report. A new roof doesn’t just add value on paper — it removes the single biggest red flag a buyer’s inspector can find, and it means you’re not negotiating a credit off your sale price to cover a roof that should’ve been handled years earlier.

Why choose Top Line for a roof replacement in Portland?

Because I still walk every job myself, my crews follow safe work procedures I personally hold them to, and I’ve been doing this in this exact climate for over 30 years — I know what a Portland winter does to a roof that wasn’t installed right. We also handle residential roofing, commercial roofing, and emergency roof repair across the Portland metro, so if something comes up mid-project or down the road, you’re not starting over with a new contractor.

Every material we install is backed by the manufacturers we work with — GAF, Owens Corning, and Malarkey Roofing Products among them — and our license is active and verifiable through the Oregon CCB license search. We’re also members in good standing with the Better Business Bureau.

Portland’s a big metro with a lot of different microclimates — the tree-heavy neighborhoods on the west side deal with moss and debris differently than the more open lots east of the river. If you want to see how we tailor an approach to a totally different setting, take a look at how we handled a roofing project out in Boring, Oregon, a much more rural, forested property than most in-city Portland jobs.
