Newgenerationroof@gmail.comRoof Replacement
A roof replacement is not a new layer of shingles on top of an old problem. We remove the existing roof down to the deck, repair or replace damaged plywood, rafters, fascia, or barge boards, then build the roof back up with proper flashing and waterproofing — updating attic ventilation if it needs it.
We are a Malarkey Emerald Pro Contractor, certified since 2024, and Malarkey polymer-modified shingle systems are what we install. We will explain the shingle lines and warranty options that fit your home, project, and budget — the full detail lives on our Malarkey roofing page.

Full removal of the existing roof layer or layers so nothing is hidden or built over.
Repair or replacement of plywood decking, and rafters, fascia, or barge boards where needed. If we uncover rotted decking during tear-off, we show you the damage and get your approval before proceeding.
New Malarkey shingles installed with proper flashing, waterproofing, and the matching underlayment, starter, ridge, and ventilation components that make it a system rather than a pile of parts.
Ventilation reviewed and updated if the existing setup is not adequate — trapped heat and moisture shorten a roof's life from underneath.
Complete job-site cleanup and a quality inspection and walkthrough before we call it done.
When we replace a roof, we perform a complete tear-off rather than installing another layer of shingles over the existing roof.
Removing the existing roofing lets us inspect the roof deck, identify damaged areas that would otherwise stay hidden, and prepare the roof properly before the new roofing system goes on. If we find rotted decking, we photograph it and get your approval before proceeding.

Our process
Tell us what you are seeing. If there is an active leak, say so. If roof damage leaves your home exposed to the weather, we can provide emergency roof tarping to help protect the property until permanent repairs can be completed.
We get on the roof, inspect it properly, and document what we find with photos so you can see the same thing we see instead of taking our word for it.
Repair or replace, and why. You pay only for what you agree to, with the scope and price confirmed before we start.
We protect landscaping and surrounding areas, monitor the weather, and secure coverings if rain moves in mid-project.
We thoroughly clean the jobsite when the work is complete — something our customers regularly mention in their reviews.
A quality inspection and walkthrough at the end. For roof replacements, a deposit is due before work begins and the remaining balance is due after all contracted work is completed. For most repairs and smaller services, payment is due after the work is completed.
Reviews
“Fast, efficient, kind, knowledgeable, reliable. Totally recommend.”
“They got our roof done in 3 days. They were super sweet, and did great work.”
“I am truly amazed and thrilled with the terrific job the crew did when they replaced my roof this week!! It took them less than 2 days to completely tear off and replace the entire roof on my 1100 sq.ft home. They cleaned up so well — it looked like they were never there! I LOVE my new roof!!”
FAQ
Most residential roof replacements take 1–3 days depending on the size and complexity of the roof. Weather can extend that timeline.
In the Portland area we plan for it. Our team watches local conditions and plans the schedule with you. If rain moves in mid-project, we secure coverings so your home stays dry.
Yes. Most homeowners stay put. Expect noise and vibration through the house while tear-off and installation are underway.
Malarkey is our preferred shingle manufacturer, and we install Malarkey polymer-modified shingle systems with the matching underlayment, starter, ridge, and ventilation components. Malarkey has manufactured in Oregon since 1956, and algae-resistant granule options are available on certain lines.
Reroofing adds another layer of shingles over the existing roof to save on tear-off, disposal, and labor. We do not offer it. We perform complete tear-offs on roof replacement projects so we can inspect the roof deck, address damaged areas, and properly prepare the roof for the new roofing system.
For roof replacement projects, a deposit is due before work begins and the remaining balance is due after the contracted work is completed. For most repairs and smaller roofing services, payment is due after the work is completed. Specific payment terms are included with your estimate or contract.

Warranty & workmanship coverage
A roof is only as good as the labor holding it together and the materials on top. You get a written warranty on both.
This is New Generation Roofing's own labor warranty on the roof replacements we install. It covers our work — flashing, fastening, sealing, and detail work. It is separate from anything the manufacturer provides.
Separately, the materials carry Malarkey's own product and system warranty. Coverage and any non-prorated period depend on the shingle line and system installed on your roof. This is the manufacturer's warranty, not ours — the two are not the same.
Malarkey's manufacturer warranties depend on correct installation. As a Malarkey Emerald Pro certified contractor, we install complete tear-off systems to the manufacturer's specification so your coverage stands.
Malarkey runs a Secure Choice™ program for qualifying roofing systems, which can provide enhanced or extended warranty protection when the requirements of the applicable program are met. Eligibility depends on the products, accessories, and installation used on your specific roof — so ask us about qualifying Malarkey Secure Choice™ roofing systems and available warranty protection during your estimate, and we will tell you plainly what your roof does and does not qualify for.
Not every roof qualifies, and no Malarkey program applies automatically. Current program requirements and warranty terms are published by Malarkey; we hand you the applicable documents in writing with your estimate.
Coverage summary only. Our 10-year workmanship warranty applies to our installation work. Malarkey's manufacturer warranty is a separate warranty covering the materials, issued by Malarkey. Full terms, exclusions, and transfer conditions are provided in your estimate and Malarkey's published warranty documents.
Inspection, photos of what we find, and an honest recommendation — no pressure, no sales pitch.
