We install 24-gauge and 26-gauge standing seam in Galvalume and pre-painted steel. Concealed fastener system means nothing's exposed to weather. Panels lock together at the seam and clip to the roof deck.

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

TPO single-ply membrane in 60-mil or 80-mil thickness, hot-air welded seams, fully adhered or mechanically attached over polyiso insulation board. We install per NRCA and manufacturer specifications. Ponding water is the number one cause of flat roof failure. We use tapered ISO insulation to create minimum 1/4" per foot slope to drains. FM 4473 rated systems available for hail-prone Grand Portage areas.

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

Improperly sized gutters cause fascia board rot and foundation erosion. We calculate gutter capacity using the rainfall intensity formula: roof square footage x pitch factor x rainfall rate (inches/hr for Grand Portage). Standard 5" K-style handles 5,520 sq ft of effective roof area. Bigger roofs or steeper pitches need 6" gutters with 3x4" downspouts. We hang with hidden hangers screwed into rafter tails every 24".

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 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.

Vented skylights open to let hot air escape. Great for kitchens and bathrooms in Grand Portage. Fixed skylights are cheaper and simpler. Solar-powered options from VELUX qualify for the federal 30% tax credit through 2032.
