Complete tear-off
Full removal of the existing roof layer or layers so nothing is hidden or built over.
Roof Replacement
Roof Replacement in Happy Valley, Clackamas & the East Portland Area
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.

Signs it may be time to replace your roof
- Cracked, curled, or missing shingles across multiple areas
- Heavy granule loss — black spots on the roof, grit in the gutters and downspouts
- A sunken or wavy roof surface, which can mean the decking below is compromised
- A 3-tab roof past 15–20 years, or a dimensional roof past 25–30 years
- Repeat leaks that keep coming back in new places after each repair
- Neighbors on the same build timeline replacing their roofs
What a roof replacement includes
Deck and wood repairs
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 roof system installation
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.
Attic ventilation updates
Ventilation reviewed and updated if the existing setup is not adequate — trapped heat and moisture shorten a roof's life from underneath.
Site cleanup and final inspection
Complete job-site cleanup and a quality inspection and walkthrough before we call it done.
We don't cover up the old roof
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
How we handle roof replacement
- Step 1
Call or request an estimate
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.
- Step 2
On-site inspection with photos
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.
- Step 3
An honest recommendation and an estimate
Repair or replace, and why. You pay only for what you agree to, with the scope and price confirmed before we start.
- Step 4
Property protection during the work
We protect landscaping and surrounding areas, monitor the weather, and secure coverings if rain moves in mid-project.
- Step 5
Complete jobsite cleanup
We thoroughly clean the jobsite when the work is complete — something our customers regularly mention in their reviews.
- Step 6
Final walkthrough
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
What homeowners say about working with us
“New Generation Roofing was our first choice for a roof replacement in the suburbs of the PNW. They offered the most competitive quote, and were patient and consistent in following up with me when I was researching various options. Every question I asked was answered in detail, and they came out personally to assess our roof and provide a quote. The actual work was done primarily across 3 days. The crew was efficient, provided updates and pictures as they went along, and did not cause any interruptions or inconveniences for my day to day work. The finished roof looks excellent and they were prompt in providing me with all the documentation needed to reflect the changes made and warranty received.”
“I am very pleased with this company. I contacted several companies, and this one turned out to be the best. They completed the work very quickly, and communication was excellent. I highly recommend this company to everyone.”
“New generation roofing is a great company. They are family business with family values and it shows. The team was great the entire process even during delays and set backs due to weather or unforeseen issues coming up — it was always a smooth process. We had to make several changes during the project and they were able to accommodate which was just awesome. I really appreciated that given how stressful construction projects are it was great being able to have trust in the team. I would highly recommend them any day to anyone. Thank you new generation for the awesome service and awesome roof!!”
FAQ
Roof Replacement questions we get asked
How long will it take to replace my roof?
Most residential roof replacements take 1–3 days depending on the size and complexity of the roof. Weather can extend that timeline.
What if it rains during my roof replacement?
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.
Can I stay in my home during the replacement?
Yes. Most homeowners stay put. Expect noise and vibration through the house while tear-off and installation are underway.
What materials do you use?
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.
What is the difference between a roof replacement and a reroof?
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.
When is payment due?
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
Your roof is covered twice: our workmanship and Malarkey's materials
A roof is only as good as the labor holding it together and the materials on top. You get a written warranty on both.
Our 10-year workmanship warranty
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.
Malarkey's manufacturer coverage
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.
Installed by an Emerald Pro certified contractor
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 Secure Choice™ roofing systems
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.
