New Roof Installation
New construction underlayment per IRC R905 and ASTM D226 (felt) or ASTM D6757 (synthetic). Ice barrier per ASTM D1970 required at eaves in climate zones with average January temperature below 25°F.

Metal roofing works on pitches as low as 3:12 for standing seam and as low as 1:12 with specific underlayment and sealant requirements. Steep pitches look incredible in metal. We help you choose the right panel profile, material, and color for your Diagonal home.

Gutter Installation
Half-round copper gutters with round downspouts are the premium install for historic and high-end homes in Diagonal. We solder every joint on-site with 50/50 tin-lead solder. Copper weathers to a green patina in Iowa's climate over 5-7 years. For modern aluminum installs, we use Spectra Metals .027 gauge seamless stock in 25+ color options with Raytec hidden hangers rated to 25 lbs per linear foot of combined debris and ice load.

Roof Inspection
Commercial and flat roof inspections include infrared moisture scanning with Flir E8 thermal cameras. Trapped moisture in the insulation layer shows as temperature differentials on the thermal image. No need to cut core samples everywhere. We identify wet zones, then core sample the suspect areas to confirm. This approach gives you a precise repair scope at a fraction of the cost of exploratory tear-offs.

Emergency Roof Repair
Emergency tarping is step one. Stop the water. We secure heavy-duty poly tarps over the damaged area using 2x4 nailer boards attached to the deck. Once the immediate threat is contained, we schedule the permanent repair within 48-72 hours.
