GAF Timberline HDZ shingles with StrikeZone nailing area for Class 4 impact resistance rated to UL 2218. We install the full GAF Roof System. Cobra ridge vent, FeltBuster synthetic underlayment, Starter Match starter strip, and Seal-A-Ridge caps. That qualifies your Cottage Grove home for the Golden Pledge warranty: 25-year workmanship plus 50-year material.

After we fix your roof, we send you before-and-after photos and a written warranty. If it leaks again from the same spot within 5 years, we come back free. That's the deal.

Wind speeds over 60 mph cause shingle tab lift and seal failure. Hail over 1" diameter causes fractures through the shingle mat to the fiberglass reinforcement. Our HAAG-trained inspectors know the difference between cosmetic damage and functional damage. That distinction determines your insurance payout.

We install new roofs on new construction, room additions, detached garages, and covered patios. Our Cottage Grove crews handle residential and light commercial. Standard install time is 1-3 days depending on size.

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.

Three-tab shingles are cheaper upfront but they don't hold up like architectural. We recommend them for sheds, detached garages, and rental properties where budget matters more than aesthetics. For your Cottage Grove home? Go architectural.

Commercial flat roof replacement in Cottage Grove starts with a core sample to check the existing insulation. If it's waterlogged, everything comes off. If it's dry, we can sometimes overlay. Saves you $2-$4 per square foot.

Commercial roofing in Cottage Grove means dealing with rooftop HVAC units, drains, parapet walls, and penetrations. We work around your equipment and schedule repairs or installs to minimize business disruption.

If your gutters overflow during rain, they're either clogged, undersized, or pitched wrong. Sometimes all three. We'll assess the issue and fix it. Might be a cleaning, might be a replacement.

Annual roof inspections catch small problems before they become expensive ones. A cracked pipe boot is a $150 fix. Ignoring it means $3,000 in ceiling and wall water damage. We recommend an inspection every 2-3 years for roofs under 10 years old, and annually after that.

Emergency roof repairs for active water intrusion follow a strict protocol: tarping with reinforced polyethylene sheeting secured to the roof deck, interior water extraction guidance, and temporary flashing at penetrations. Our Cottage Grove emergency crews carry 20x30 tarps, 2x4 nailer boards, and masonry anchors for various deck types. Permanent repairs are scheduled within 48-72 hours once materials are sourced.

A skylight installed wrong will leak. The flashing has to integrate with the shingle courses. Step flashing on the sides, headwall flashing on top, and a sill pan underneath. We use manufacturer flashing kits because they're engineered to work with the skylight frame.
