Grand Marais Roofing Contractor. GAF Certified

Replacing your roof isn't just about shingles. We install ice and water shield in the valleys and along eaves, synthetic underlayment across the whole deck, new drip edge on rake and eave, starter strip, and ridge vent. That's how a roof lasts 30 years in Michigan.

Step flashing at chimney walls is the number one leak source we see in Grand Marais. Improper step flashing causes roof leaks. It's that simple. We install new step flashing with a chimney cricket for proper water diversion, sealed with Geocel tripolymer sealant. Fix it once, fix it right.

Hail, wind, fallen branches. Michigan storms do real damage to roofs. We respond within 24 hours, tarp exposed areas to prevent further damage, and start your insurance claim with a detailed inspection report.

New construction roof installation following IRC Section R905 and local Grand Marais building code amendments. We calculate ventilation per IRC R806 (1:150 ratio reduced to 1:300 when 50% is within 3ft of ridge. Synthetic underlayment per ASTM D226, ice barrier per ASTM D1970 at eaves in freeze-thaw climate zones. Manufacturer-certified installation locks in the full system warranty.

Metal roofing costs more upfront at $12-$22 per sq ft installed in Grand Marais compared to $4-$8 for shingles. But it lasts 2-3x longer and your energy bills drop 15-25%. Math works out over time.

Asphalt shingle roofing is the most common and cost-effective roofing system in Grand Marais. Our crews install 15-20 shingle roofs a month. We know the product inside and out. Nailing patterns, exposure measurements, hip and ridge details.

Flat roof leaks usually happen at penetrations, seams, or flashing details. We locate the source, repair it properly, and coat the surrounding area. If the membrane is shot, we'll recommend replacement. Not a band-aid.

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

Gutters aren't glamorous, but they're protecting your foundation, your fascia, and your landscaping. We install seamless aluminum gutters custom-formed on-site from a roll of coil stock. No seams means no leaks.

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.

Fallen tree limb damage requires structural assessment before repair. We check rafter integrity, decking condition, and whether the ceiling joists below were impacted. If structural members are cracked or displaced, you need a framing carpenter before we re-roof. We coordinate with trusted Grand Marais contractors for structural work. Insurance carriers require separate line items for structural vs. roofing repairs. We document both.

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.
