Professional Pennock Roofing Contractor. GAF Certified

Our Pennock crews tear off and replace 15-20 roofs a month. That kind of volume means tight installs, clean job sites, and no wasted time. Most homes are done in a day. Two-story steep-pitch jobs take two.

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.

Hail, wind, fallen branches. Minnesota 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 Pennock 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 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.

Your shingle choice determines your warranty, your curb appeal, and how your roof handles Minnesota weather. We'll show you samples, explain the differences, and let you pick what fits your budget. No pressure.

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 Pennock areas.

Our Pennock commercial crews handle everything from small retail strip centers to 50,000 sq ft warehouses. TPO, EPDM, modified bitumen, metal. We're certified installers for all major commercial membrane systems.

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 Pennock). 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".

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.

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 Pennock contractors for structural work. Insurance carriers require separate line items for structural vs. roofing repairs. We document both.

VELUX FS fixed skylights and VS vented skylights installed with EDL flashing kits for profile roofing. The flashing integrates with your shingle courses per IRC R903.2 weather protection requirements. We cut the opening, frame the curb with doubled 2x lumber, install the skylight with factory sealant, and weave the flashing into the existing shingle field. Leak-proof when done right. And we do it right in Pennock.
