Cottage Grove Roofing Contractor: Roof Replacement, Repair & Storm Roofing
If you are looking for a roofer in Cottage Grove, you are looking at the one whose office is here. Northern Exteriors handles full roof replacement, targeted roof repair, and hail and wind storm roofing for Cottage Grove homes in 55016, from Old Cottage Grove to the newer neighborhoods on the south and east sides. Every job starts with a free, photo-documented roof inspection and a written scope that covers tear-off, deck, ice-and-water, flashing and ventilation, not just a shingle color. Licensed (MN #BC297099), A+ BBB, 4.9 stars on Google, owner-led since 2001. Call or text 651-230-5103 or request your inspection below.
Northern Exteriors is a family-owned roofing and siding contractor based in Cottage Grove. This is not just another dot on our service-area map: Cottage Grove is our hometown, our office is here, and we have served local homeowners since 2001. That gives customers something more useful than “near me” copy—a contractor who expects to see the same homeowners, neighbors and streets for years after the project is finished.
We inspect aging roofs, diagnose leaks, document possible storm damage, replace roofing and install siding throughout ZIP code 55016. If you are unsure what the exterior needs, start with a roof and exterior inspection. We will explain what is urgent, what can be repaired and what can simply be monitored.
Cottage Grove Is Home—Accountability Is the Advantage
A local address does not automatically make a contractor good, but it does make accountability harder to fake. Northern Exteriors has built its reputation through repeat work, referrals and projects completed around Cottage Grove and Washington County. We are not arriving for one storm season and disappearing when the signs come down.
Our work ranges from established homes near Old Cottage Grove to newer neighborhoods on the city’s south and east sides. Roof age, ventilation, flashing design and prior repairs vary widely, so we inspect the actual house rather than assigning the same answer to every neighborhood.

Roof Repair, Replacement and Storm Inspections
A leak does not automatically mean the whole roof has failed. Water may enter at a pipe boot, chimney, sidewall, skylight or damaged shingle and travel before it becomes visible indoors. We evaluate the shingles, accessible decking, flashing, penetrations, gutters and ventilation before recommending a scope.
When replacement is justified, the written proposal should identify more than the shingle color. It should address tear-off, deck repairs, ice-and-water protection, underlayment, drip edge, valleys, roof-to-wall flashing, penetrations, ventilation and cleanup. We install architectural shingles from established manufacturers and can discuss Class 4 impact-rated shingles when the testing, cost and possible carrier-specific insurance discount fit the homeowner’s priorities. Class 4 does not mean hail-proof. One Class 4 option we install is Malarkey Legacy® — see our Malarkey roofing page.
Cottage Grove Requires Concealed Roofing Details to Be Photographed
The City’s current permit guidance says roofing projects must upload ice-and-water membrane photos to the online permit before the final inspection can be scheduled. That requirement matters because the most important protection at eaves and valleys disappears beneath the finished shingles.
Our project process includes permit coordination and documentation of concealed work before it is covered. If the roof deck requires replacement or an unusual flashing condition appears during tear-off, the homeowner is shown what changed and why.
Siding That Manages Water Behind the Finished Wall
Northern Exteriors installs LP SmartSide, vinyl and steel siding. None is automatically best for every house. We compare appearance, maintenance, budget, impact behavior, wall condition and whether an existing profile can be repaired or matched. For siding repair, replacement, LP SmartSide and vinyl options, storm-damaged siding documentation and a local project photographed four winters after installation, see our dedicated Cottage Grove siding contractor page.
Cottage Grove’s residential siding requirements call for clear photos of the weather barrier, taped seams, overlapped corners and flashing before final inspection. That is the right focus: siding is the visible cladding, but housewrap and flashing around windows, doors and roof intersections control whether incidental water gets back outside.

Storm Documentation Without Insurance Promises
Hail and wind can damage shingles, siding, vents, gutters and other exterior components, but a weather report alone does not prove damage at a specific Cottage Grove address. We photograph visible conditions and distinguish possible storm effects from ordinary aging or maintenance. If a claim is filed, we can meet the adjuster and answer construction questions; the carrier decides coverage under the policy.
Our inspection is free and no-pressure. Some homes need replacement, some need a targeted repair and some need no immediate work. “Nothing urgent” is a perfectly acceptable inspection result.

Cottage Grove Roofing & Siding FAQs
Is Northern Exteriors actually based in Cottage Grove?
Yes. Our office is in Cottage Grove, and we have served local and Twin Cities homeowners since 2001.
How long will my roof replacement take?
Many straightforward residential roofs can be completed quickly, but size, pitch, weather, access, tear-off layers and deck repairs affect the schedule. We give a project-specific estimate instead of promising every roof will be finished in one day.
Can a roof leak be repaired?
Often, yes. Repairability depends on the leak source, roof age, surrounding material condition and whether compatible materials are available.
Do you handle both roofing and siding?
Yes. Coordinating both scopes is especially valuable where siding, step flashing, kick-out flashing, fascia, soffit and gutters meet.
Are you a licensed roofing contractor in Cottage Grove, MN?
Yes. Northern Exteriors holds Minnesota contractor license BC297099, carries an A+ BBB rating and has been based in Cottage Grove since 2001. We pull the City permit and upload the ice-and-water photos Cottage Grove requires before final inspection.
How much does a roof replacement cost in Cottage Grove?
It depends on roof area, pitch, tear-off layers, deck condition, flashing, ventilation and the shingle system. We measure and inspect first, then give a free written scope rather than a generic internet price range.
Do you do hail damage roof inspections in Cottage Grove?
Yes. The inspection is free, on the roof when weather and safety allow, with photos and a written summary. If we do not find hail or wind damage we say so, and if we do we can meet your adjuster on site. Your insurer decides coverage.
Can you repair a roof leak instead of replacing the roof?
Often, yes. Repairability depends on the leak source, roof age, surrounding shingle condition and whether compatible materials are available. We tell you which option the evidence supports.
