A statewide housing stock of more than 638,000 homes means exterior upkeep is a practical, everyday need across the Granite State. The weather data also shows why the timing and condition of each property matter. Annual precipitation varied from 40.03 inches in 2025 to 56.30 inches in 2023, while annual average temperature ranged from 44.5 F to 46.7 F over the same period.
Those statewide figures do not predict the condition of one driveway, deck, or house exterior. They do explain why shaded surfaces, hardscapes, gutters, siding, and outdoor living areas can need different attention from one season to the next. For a property-specific recommendation, look at the surface, the buildup, drainage, shade, and how the space is used.
