A roof replacement is more than pulling off old shingles. At Dema Roofing & Maintenance, we do a complete tear-off down to the decking, inspect every board for moisture damage or rot, and build your new roofing system from the deck up. Every layer installed to manufacturer specifications.
A roof system is more than the shingle on top. We install ice and water shield at valleys and penetrations, synthetic underlayment across the full deck, aluminum drip edge, proper starter strip, and ridge vent for balanced attic ventilation. Every layer matters for longevity.
