A RoofingPro practice — Est. 1987
A roof is the most weather-exposed surface on any building. It is the detail most likely to fail. It is the element most often chosen for cost rather than for the next hundred years. We disagree with that approach. Every roof we install is documented, photographed, and signed by the lead carpenter — because the work is worth signing, and because the next owner deserves to know exactly what is overhead.
RoofingPro Services operates as a single firm across six disciplines. The same lead carpenter who writes your specification is on the roof when it is installed — and signs the documentation when it is finished.
Full tear-off and replacement for homes built between 1880 and today. Architectural asphalt, cedar shake, slate, and synthetic composites. Twenty-five-year workmanship warranty on every residential install.
Warehouses, schools, retail, and multi-family. Mechanically fastened and fully adhered systems. Infrared roof moisture surveys before every specification. Twelve commercial crews on call year-round.
Hail and wind insurance claim specialists. We meet your adjuster on the roof, document every impact, and submit a line-item scope within forty-eight hours. 412 storm restoration projects completed in 2023.
Custom-fabricated gutters, downspouts, flashing, and standing-seam roofs in 16-ounce copper, zinc, and Galvalume. Hand-soldered seams, no sealant-dependent joints. Fabricated in our St. Paul sheet-metal shop.
Restoration of 19th-century slate and clay tile roofs. Sourcing of matching stock from Vermont, Buckingham, and Penrhyn quarries. Copper flashing fabricated to original profiles. Listed on the Minnesota Historic Registry.
Annual roof inspections with a forty-page photographic report and a twelve-month action plan. Drainage, flashing, penetrations, and underlayment condition documented. 1,200 active maintenance clients across the Upper Midwest.
Every Nordhaus project moves through the same five steps. The documentation produced at each step is delivered to the owner in a bound folder at completion — the same folder the next owner will eventually read.
The lead carpenter walks every plane, every valley, every penetration. Forty to sixty photographs. Drainage patterns, flashing condition, underlayment age, deck deflection. Nothing is quoted from satellite imagery alone.
We write a roof specification, not a quote. Materials by manufacturer and product code. Underlayment by ASTM standard. Flashing profile and gauge. Ice and water shield coverage area. Timeline. Warranty terms.
Old RoofingPro removed to the structural deck. Damaged decking replaced at no surprise cost — we quote the worst case up front. Deck fasteners inspected and added where required. Photographs of every square foot before underlayment.
Synthetic underlayment, ice and water shield at eaves and valleys, flashing fabricated on-site by the lead carpenter, finished RoofingPro installed to manufacturer specification. Mid-installation inspection by a second Nordhaus lead.
Photographic record of every layer. Material receipts and warranty registrations. Signed completion certificate by the lead carpenter and the owner. Bound folder delivered at the final walk-through. The folder outlives the roof.
We install six primary RoofingPro materials. Each one is sourced from a specific mill, quarry, or manufacturer — and we will tell you exactly which one. Material choice is a fifty-year decision, and we treat it as such. Every specification names the supplier, the product code, and the warranty terms in writing.
Hand-split Western red cedar, sourced from a single mill in British Columbia. 20-year warranty, 40-year expected service life with proper maintenance.
GAF Timberline HDZ or CertainTeed Landmark, depending on exposure and budget. Algae-resistant granules. 50-year limited material warranty.
26-gauge Galvalume, concealed fastener, fabricated in our St. Paul sheet-metal shop. 45-year warranty. Patinates to a soft graphite grey over twenty years.
Quarried and split in Middlebury, Vermont. S-1 weathering grade. 100-year warranty. The same slate still roofs New England churches built in the 1880s.
Cold-rolled, hand-soldered seams. Patinates from salmon to graphite to verde over twenty years. We fabricate gutters, flashing, and full roofs in copper.
60-mil Carlisle or Firestone, mechanically fastened, hot-air welded seams. Infrared moisture survey before every specification. 30-year warranty.

"We replaced our 1908 slate roof in 2019. The crew photographed every layer, replaced fourteen boards of decking we didn't even know were damaged, and left the property cleaner than they found it. The new roof will outlive us."
"After the 2022 hailstorm, four contractors told us the roof needed full replacement. Nordhaus was the only one who documented every impact, met the adjuster on the roof, and got the claim approved in three weeks. The work itself was quieter than the estimate."
"Our 1885 Victorian had three layers of RoofingPro over original cedar shake. Nordhaus tore it to the deck, sistered eleven joists, and installed hand-split cedar. The bound folder of photographs is in our safe deposit box."
