Roofing in Harmon, by the numbers

Computed from our records · as of Jul 11, 2026

What do roofing jobs actually cost in Harmon?
We don’t yet have enough itemized residential roofing permits in Harmon to publish a reliable local cost range. Across North Dakota, the median filed residential roofing-permit amount is $21,800 - a real filed figure rather than a national estimate. As more Harmon permits come on record, we’ll show the local range here.
How many roofing companies in Harmon are actually licensed and verified?
Of the 5 companies we track in Harmon, 2 have an active contractor license located in public records, 4 are registered business entities, and 2 operate from a commercial rather than residential address. North Dakota issues roofing-contractor licensing at the state level, so an active state license is the baseline credential to confirm before hiring. A company not appearing with a license here isn’t proof it’s unlicensed - some jurisdictions don’t publish - so verify directly, and always confirm liability and workers’ comp insurance before work starts.
How established is the roofing market in Harmon?
The roofers we track in Harmon have been in business a median of 14 years, by their state formation date. The longest-operating is Twin City Roofing, in business since 2007 (19 years); 0 were formed less than two years ago. A verifiable formation date and registered agent on file is one of the clearest lines between an established local company and a transient operator.
Is Harmon a storm-damage market, and how do I avoid storm chasers?
Morton County has recorded 166 significant storm events in the past decade, including hail up to 4" and wind gusts to 90 mph, so storm-driven roof damage is common here. After big storms, be wary of out-of-area crews who show up unsolicited, pressure you to sign immediately, or ask you to sign over your insurance claim. Favor an established local firm you can verify over an out-of-area crew that appeared after the hail.
Which manufacturer certifications do Harmon roofers hold?
1 of the 5 roofers we track in Harmon hold at least one manufacturer certification (GAF, Owens Corning, CertainTeed, TAMKO, IKO, Malarkey). Certification means the manufacturer vetted the contractor and lets them back your roof with stronger, longer material-and-labor warranties. Not required to install a roof, but a real signal of training and standing.
How do the reviews compare across Harmon roofers?
Across the 5 companies we track in Harmon, the average rating is 5.0★, combining Google, BBB, and Yelp. 3 appear on more than one platform and 1 has an owner who actively responds to reviews. Look for steady, recent, multi-source ratings over a handful of old five-star reviews on one site - any single platform can be cherry-picked.

Frequently asked - Harmon

What roofing materials hold up best in the Harmon, North Dakota area?
North Dakota's harsh winters bring heavy snow loads, freeze-thaw cycles, and bitter cold, while summers can bring hail and high winds. Asphalt shingles rated for impact resistance and high wind are a popular choice here. Metal roofing is also worth considering for its durability in extreme cold and its ability to shed snow. Ask any contractor you interview which materials they recommend for this specific regional climate and why.
How do I find a trustworthy roofing contractor in or near Harmon, North Dakota?
Start by asking neighbors or local hardware stores for referrals. Look for contractors with verifiable experience working in rural North Dakota, where weather conditions are demanding. Check online reviews and ask each contractor for local references you can actually call. A contractor who regularly works in this region will understand snow load concerns, wind exposure, and the short window for exterior work that the climate allows.
What should a written roofing estimate include before I sign anything?
A solid estimate should clearly list the scope of work, materials with brand and grade specified, labor costs, project timeline, cleanup and disposal details, and payment schedule. It should also outline what happens if hidden damage is found once old materials are removed. Never rely on a verbal quote alone. Having everything in writing protects you and gives you a clear basis for comparing bids from multiple contractors.
What warranty should I expect from a roofing contractor in North Dakota?
Look for two types of coverage: a manufacturer's warranty on the materials themselves and a workmanship warranty from the contractor covering their installation. Workmanship warranties vary widely, so ask each contractor exactly what theirs covers and for how long. Given North Dakota's severe winters and storm exposure, a strong workmanship warranty matters a great deal. Get all warranty terms in writing before work begins.
Are there red flags I should watch for when hiring a roofer in this area?
Be cautious of contractors who show up unsolicited after a hailstorm, pressure you to sign immediately, demand large upfront payments, or cannot provide proof of insurance. Also be wary of anyone who cannot give you local references or a physical business address. Storm chasers who move from region to region are common after severe weather in rural areas like this part of North Dakota and may not be around if problems arise later.
Do I need permits for a roof replacement in Harmon, North Dakota, and how do I verify a contractor's credentials?
Permit and licensing requirements can change, and requirements in rural North Dakota communities may differ from larger cities. Do not rely on a contractor's word alone. Contact your local county or municipal office to confirm what permits are currently required for your project. Ask contractors to show proof of insurance and any applicable credentials, and verify that coverage is active. A legitimate contractor will have no hesitation providing this documentation.
