Berthold Roofing & Maintenance has been installing asphalt shingle roofs across Berthold for 21 years. GAF Timberline HDZ, Owens Corning Duration, CertainTeed Landmark — we carry the top shingle lines and we're certified by the manufacturers to install them.
We install every shingle roof to manufacturer specifications. That means 4-6 nails per shingle in the designated nailing zone, proper offset between courses, starter strips along the eave, and ridge cap shingles at every hip and ridge. When the manufacturer inspector shows up, your roof passes.
Our Shingle Roofing Process
Free Roof Estimate
We inspect your existing roof deck and sheathing, measure the area, and help you choose between architectural and three-tab asphalt shingles. Color samples brought to your Berthold home.
Tear-Off & Deck Prep
We strip the old shingles, underlayment, and damaged flashing down to the roof deck. Every square foot of OSB or plywood sheathing inspected for rot, water damage, and soft spots. Compromised decking replaced before new materials go down.
Underlayment & Flashing
The waterproofing layer is what protects your home if a shingle ever fails. We install ice-and-water shield at every vulnerable point — valleys, eaves, penetrations — then roll synthetic underlayment over the entire deck. Drip edge directs water into gutters, not behind fascia boards.
Shingle Installation
Field shingles installed with proper exposure and overlap. Nailed per manufacturer specs — 4 nails standard, 6 in high-wind zones. Starter strips at the eave prevent wind uplift. Ridge cap shingles finish every peak with integrated ridge vent for ventilation.
