New Roof Installation
For Portsmouth new builds, we recommend Tamko Heritage or Malarkey Vista AR for budget-conscious projects and Atlas Pinnacle Pristine with Scotchgard for algae-resistant performance. High-end builds get GAF Timberline HDZ or Owens Corning Duration STORM. Each carries different warranty tiers. We walk you through the comparison so you're choosing with real information, not marketing brochures.

Metal Roofing
Metal roofing reflects solar heat instead of absorbing it. In Iowa, that means 15-25% lower cooling costs compared to dark asphalt shingles. The higher upfront cost pays for itself over the life of the roof. And the life of a metal roof is twice or three times longer than shingles.

Shingle Roofing
The difference between a cheap shingle roof and a quality one comes down to the system underneath. Shingles are only the outer layer. Ice and water shield in the valleys, synthetic underlayment across the deck, proper starter strip with factory adhesive, correct nailing pattern. That's what makes a shingle roof last in Iowa's weather.

Gutter Installation
Clogged gutters cause fascia rot, soffit damage, and foundation erosion from concentrated water runoff. That's not a marketing scare tactic. We see the damage on every other gutter replacement in Portsmouth. Properly sized gutters with adequate downspout capacity move water away from the house. We calculate capacity using rainfall intensity data for Portsmouth: roof area x pitch factor x rainfall rate in inches per hour. Standard 5" K-style handles 5,520 square feet of effective roof area.

Roof Inspection
Annual inspections catch small problems early. A cracked pipe boot is a $150 repair. A year of water leaking through that crack causes $3,000+ in ceiling, insulation, and drywall damage. We recommend an inspection every 2-3 years for newer roofs, annually for roofs over 15 years.
