About This Market
Dover's roofing market runs hot from spring through fall, driven by coastal weather that batters shingles and creates ice dam nightmares every winter. You've got about 65 licensed outfits statewide competing for work, with most clustered around Portsmouth and Manchester. Coastal location means salt air corrosion, heavy snow loads, and wind damage from nor'easters. Asphalt shingle replacements dominate residential work, but metal roofing's gaining ground for durability. Costs run 10-15% above national average due to material transport and skilled labor shortage. Getting licensed in New Hampshire isn't rocket science, but the paperwork's no joke. You need your Home Improvement Contractor Registration, which means passing their exam, posting a $25K bond, and proving insurance. Dover's building department moves fast on permits and inspections if you stay on top of them. Peak season books solid by March, so line up your crews early. Ice dam work pays premium rates but it's dangerous - know your safety protocols. Local suppliers in Portsmouth and Rochester, but expect delays during busy season.
