Replacement

When Repair Stops Making Sense

A repair is the right call for isolated damage on a roof that still has life in it. Once a roof passes roughly twenty years, or once you are patching the same slope for the second or third time, the math changes. You are spending money on a system that needs replacing anyway, and every patch adds one more seam that can fail.

Signs You Are Past Repair

Granules collecting in the gutters, shingles curling or cupping at the edges, bare asphalt showing through, leaks appearing in different spots, and daylight visible in the attic all point to a roof that is finished as a system. So does a deck that feels soft underfoot, which usually means moisture has been getting through for a while.

What Actually Goes On Your Roof

A replacement is not just shingles. We tear off to the deck so we can see what we are working with, replace any rotted sheathing, then rebuild the system: ice and water shield at the eaves and valleys, synthetic underlayment across the field, new flashing and pipe boots, GAF architectural shingles, and proper ridge and intake ventilation. Ventilation is the most commonly skipped step in this trade, and skipping it is what cooks a roof early.

How Long It Takes

Most residential replacements in McHenry County run one to two days depending on square footage, pitch, and how many layers are coming off. We tear off and dry in on the same day, so your home is never left open overnight.

Cleanup

We use the Catch-All landscape protection system on every tear-off and run magnets across the lawn and driveway before we leave. The thing customers mention most often in our reviews is that they could not tell we had been there.

Warranty and Financing

Gen Ex is a GAF Certified Plus contractor, which lets us offer manufacturer warranty coverage most roofers cannot. We back our own work with a 10-year workmanship warranty on top of that. Financing is available if you would rather spread the cost, and we offer a discount for active military and veterans.

We Proudly Use the:

Catch-All home and landscape protection system

The Catch-All home and landscape protection system is designed to provide your home and landscaping with the ultimate protection during roof tear-off projects. The netting used protects lawns and landscaping from burning or suffocating under traditional tarps. This material is also designed specifically to take a beating from falling debris, in fact, the netting we use for The Landscape Protection Kit is SUPER tear resistant. In addition to protecting your home and landscaping, this system helps us ensure a clean job site once the roofing project is complete. 

GenEx did our house and shed roofs. Very professional in making sure everything was draped so that flowers, bushes, etc. we’re not damaged. Once done their clean up was also spectacular! Highly recommend them! Very pleasant to work!

Extremely easy to deal with. Honest people. Cleanup was amazing, like they were not even there. Very Happy customer!

Great people to work with. Accommodated our personal choice of roofing, promptly completed the work and everything was done professionally. I highly recommend these guys.
