Arnold Roofing Has Two Challenges Most Communities Don't Face Together: Storm Exposure and Valley Moisture.
Arnold’s position in Jefferson County’s Meramec River valley creates a specific roofing environment. The county sees significant severe weather — hail events, straight-line winds, and heavy rainfall that tests roofing systems repeatedly. And the valley’s moisture environment means roofing materials face sustained humidity exposure that accelerates certain types of wear — particularly at the underlayment level and at any point where moisture can become trapped against the roof deck.
These two factors together mean that roofing in Arnold isn’t just about what’s visible on the surface. The underlayment system beneath the shingles matters more here than in drier environments — it’s the line of defense when shingles are compromised by storm impact or age. ECI specifies underlayment appropriate for Arnold’s moisture environment and installs ice and water shield at all vulnerable points — not just at eaves where code requires it, but at valleys and penetrations where moisture infiltration is most likely.
Arnold Roofing — Specific Considerations
Impact-Resistant Shingles for Jefferson County Hail
Jefferson County’s hail season is one of the most active in the greater St. Louis area. Arnold homeowners who want longer intervals between roof replacements should consider impact-resistant shingles — Class 3 or Class 4 rated products that resist hail damage significantly better than standard asphalt. ECI installs impact-resistant options and walks homeowners through the cost-benefit comparison during the proposal process.
Underlayment Specification for Valley Moisture
Standard 15-lb felt underlayment is not the right specification for Arnold’s moisture environment. ECI uses synthetic underlayment with better moisture resistance and longer durability in high-humidity conditions.
Gutter Integration
In Arnold’s drainage-sensitive environment, the relationship between the roofing system and the gutter system is important. ECI assesses gutter condition and positioning as part of every Arnold roofing project — a new roof that drains into a failing gutter system is a problem that will manifest quickly.
