Holthaus Companies Inc. takes pride in offering the Duro-Last roofing system, “The World’s Best Roof,” when it comes to low-slope roof replacements. This system is highly durable, energy efficient, custom fabricated and sustainable. Usually we can install the Duro-Last roofing system over your existing roof whether it’s metal, shingle, gravel and more.

We offer a shingle-ply membrane roof for a more designer-style roof that mimics an asphalt shingled roof, and we offer a rock-ply roof which mimics a stone ballasted roof. Holthaus also uses many elastomeric roof coatings for low-slope roof repairs. Call us for your free roofing quote at 309-647-9209 or 888-692-6915.
