roof replacement
FREE ESTIMATE

Roof Replacement

We don't do shortcuts on replacements. Tear off the old roof, check the decking for soft spots, install synthetic underlayment, drip edge, starter strip, shingles, ridge vent. The whole system. Your roof is only as good as the layers underneath.

roof repair
SAME-DAY

Roof Repair

We repair every type of roofing. Asphalt shingles, metal panels, flat membranes, tile. Our guys carry the materials on the truck. Most repairs are same-day once we're on site.

storm damage repair
LICENSED

Storm Damage Repair

Storm damage claims in Minnesota have a 1-year filing window with most carriers. Don't wait. We'll inspect your roof, document the damage, and help you file before the deadline. If there's no damage, we'll tell you that too.

new roof installation
TOP RATED

New Roof Installation

Building a new home in Bertha? Our crew works directly with your GC or we self-perform. We handle everything from the decking up: underlayment, ventilation design, material installation, and final inspection.

metal roofing
GUARANTEED

Metal Roofing

Metal roofing in Minnesota makes sense. It reflects heat, handles high winds, and sheds hail better than shingles. We install standing seam, corrugated, and metal shingle panels.

shingle roofing
INSURED

Shingle Roofing

Owens Corning Duration STORM shingles with triple-layer SureNail reinforcement strip. Rated to 130 mph wind per ASTM D7158. Algae-resistant granules prevent black streaking in humid Minnesota climates. We install Duration in the full Owens Corning system for Preferred Protection or Platinum Protection warranty coverage. CertainTeed Landmark PRO with NailTrak technology is our alternative pick for Bertha homeowners who want the max warranty tier.

flat roofing
FREE ESTIMATE

Flat Roofing

A flat roof that's ponding water is a flat roof with a problem. We install tapered insulation systems to create positive drainage to your scuppers or interior drains. No more standing water after rain.

commercial roofing
SAME-DAY

Commercial Roofing

Flat roofs on commercial buildings are a different animal. We install and repair TPO, EPDM, modified bitumen, and built-up systems. Our Bertha commercial crew handles retail, warehouse, office, and multi-family buildings.

gutter installation
LICENSED

Gutter Installation

We install 5" and 6" seamless aluminum gutters in Bertha. Standard homes get 5", high-volume areas and steeper pitches get 6". Downspouts every 30-40 ft of gutter run with splash blocks or underground drains.

roof inspection
TOP RATED

Roof Inspection

Our 27-point roof inspection covers: shingle condition, granule loss, nail pops, lifting tabs, ridge cap integrity, valley flashing, step flashing at walls, drip edge, pipe boot seals, vent function, soffit ventilation, gutter pitch, downspout capacity, fascia condition, decking (from attic if accessible), and visible signs of moisture in the attic. Written report with photos emailed same day.

emergency roof repair
GUARANTEED

Emergency Roof Repair

Emergency tarping is the first priority. We cover the exposed area to stop water entry, then schedule the permanent repair once conditions allow. We don't charge extra for emergency tarp jobs. It's part of the repair cost.

skylight installation
INSURED

Skylight Installation

We install, replace, and repair skylights in Bertha homes. Fogged glass, cracked frames, persistent leaks around old skylights. We fix it all. Sometimes replacing a 20-year-old skylight is cheaper than trying to repair it.

Simple Process

How It Works

1

Complimentary Assessment

We climb up, walk the entire roof, and document what we find with photos and measurements. Takes about 30 minutes. You'll see exactly what we see.

2

Your Custom Proposal

We price by the roofing square with all materials itemized. You'll see exactly what you're getting. Shingle brand, underlayment type, ventilation specs, flashing details.

3

Expert Installation

Our crews average 8 years of experience each. They tear off the old roof, inspect the decking, replace any damaged boards, and install your new system from the deck up.

4

Quality Check

Our project manager does a final inspection against the manufacturer's installation checklist. We register your warranty the same day. You get the paperwork within a week.

"Storm chasers were going door to door after the hailstorm. Called Bertha Roofing & Maintenance instead because they're actually from Bertha. Got a fair deal and a warranty that means something."

"Got three quotes for a roof replacement. Bertha Roofing & Maintenance was the middle price but the only one who actually got on the roof and showed me photos. Everyone else just eyeballed it from the driveway."

FAQ

Frequently Asked Questions

We recommend GAF, Owens Corning, or CertainTeed. And we're certified by all three, so the choice is yours. In Bertha, the most popular pick is GAF Timberline HDZ in Weathered Wood or Charcoal. For hail-prone areas, look at the impact-resistant versions rated UL 2218 Class 4. We walk you through the options during the estimate.

Absolutely. A new roof shouldn't mean emptying your bank account. We have 0% intro options, low fixed-rate plans, and extended terms up to 12 years. Quick credit check, fast approval, and you can get your roof done this month instead of waiting until you've saved enough.

Common signs: curling or cracking shingles, missing shingles after wind events, granule loss (look in your gutters), daylight visible through the attic, sagging roof deck, and age. Most asphalt roofs last 20-30 years in Minnesota. If you see any of these, call (877) 586-1316 for a free inspection. We'll be honest about whether you need a replacement or just a repair.

One day for most homes. Our crews are experienced and we pre-stage materials the day before install. Bigger or steeper roofs can run to two days. The dumpster shows up at 7 AM and leaves when we're done. Your life gets back to normal fast.

The shingles carry the manufacturer's warranty. Typically 30-50 years for architectural shingles. Our installation warranty covers any defects in our workmanship. If something goes wrong because of how we installed it, we fix it at no cost. Both warranties are in writing and we provide them at the final walkthrough.
