What 45+ Years in Roofing Has Taught Us About Protecting Your Home

At Peterson Roofing we’ve been putting good roofs over heads since 1978. Over the last 45+ years serving Mount Prospect, the northwest suburbs and greater Chicagoland area, we’ve learned that protecting a home starts long before a leak shows up on the ceiling. It’s the small, regular choices; the right materials, the right details, and the right local crew that reduce surprises, extend roof life, and keep families safe and comfortable. We think about the entire roofing system, not just shingles. That mindset is what separates a roof that fails early from one that performs for decades.

Below are the hard-earned lessons we share with homeowners every day packed with practical steps you can take this season.

Inspect regularly. Every season, not just after a storm

One of the simplest habits that saves homeowners thousands is scheduling routine inspections. A professional check in the spring and again in the fall catches loose shingles, failing sealants, compromised flashing, or small penetrations that become big problems. The National Roofing Contractors Association and local pros recommend seasonal inspections because small issues compound quickly in our climate. Regular checks allow you to fix minor problems while they’re still small.

What we do for customers: our trained crews perform thorough, paid inspections that look at every roof component; ridge, valleys, flashings, vents, gutters, and attic conditions and we give you a clear plan, not a sales script.

Treat the roof as an entire roofing system including ventilation, insulation, gutters, flashing

A roof is not only shingles. It’s the ventilation and insulation under the roof deck, the flashing around chimneys and vents, the gutters that move water away, and the sheet metal details that protect edges. Problems with ventilation or insulation lead to ice dams, trapped moisture, and early shingle failure. Likewise, poorly installed flashing or loose gutters will let water back into the structure even if the shingles look fine.

We recommend a whole-system inspection and repair strategy: assess attic ventilation and insulation, tighten and replace flashing where needed, and ensure gutters are clear and properly pitched. Taking a systemic view prevents recurring problems and gives the roof the best chance to reach its designed lifespan.

Ice dams and winter moisture are preventable

Ice dams form when warm attic air melts snow on the roof and water refreezes at the eaves, creating a ridge that traps water behind it. That trapped water can back up under shingles and cause leaks and rot. The most effective ways to prevent ice dams are improving attic insulation and ventilation and keeping gutters clear so water can flow freely. In our winters, acting early before heavy snow is the key.

If you see repeated eave icicles, interior ceiling stains after freezes and thaws, or large snow build-ups near your gutters, call us to evaluate the attic and the roof edge details.

Safe Snow removal

Heavy, wet snow can add surprising weight and stress to a roof. Homeowners often want to “shovel the roof” themselves, but climbing onto icy roofs is dangerous. The safest approach is to use a roof rake from the ground to remove excess snow at the eaves and near valleys; for steep or complex roofs, hire professionals. Using safe methods prevents injury and minimizes damage to shingles and flashing.

We advise homeowners to clear critical areas (gutters and valleys) after big storms and to avoid DIY repairs in icy conditions. If professional removal is needed, we have trained crews and the right equipment to protect your home and your family.

Secure flashing and roof penetrations (tiny gaps cause big leaks)

A large portion of roofing leaks start at flashings, pipe collars, chimneys, and skylight edges. Wind, thermal cycling, and age cause sealants and flashing metal to fail before the shingles might. Properly installed and maintained flashings and roof-to-wall connections are essential. Securing these details is a cost-effective way to protect your home from wind and hail-related problems.

Our crews are trained in modern flashing techniques and complete installation details in our in-house training facility, so these elements are done right the first time.

Gutters and water management matter as much as shingles

A well-installed shingle system paired with clogged or failing gutters won’t keep water out. Gutters that are full, sagging, or detached allow water to pond at the eaves, create ice dams, and direct moisture into siding and foundations. We recommend cleaning and inspecting gutters at least twice a year and checking fasteners and downspouts.

We also encourage homeowners to make sure downspouts take water far enough away from the foundation to avoid long-term moisture problems. Small investments in gutter health prevent large interior and exterior repairs down the road.

Local expertise beats nationwide storm-chasing every time

We’ve seen it: crews who arrive after a big storm, do quick patchwork, and disappear. Those short-term fixes often leave homeowners with worse problems. We’re a local company licensed, bonded, and operating in Mount Prospect since 1978 (License #104-002674) and our reputation is built on long-term relationships and follow-through. We keep customer files going back decades and stand behind our installation practices. When you hire local, you’re hiring someone who will be around after the storm if adjustments are needed.

Don’t delay obvious repairs (small leaks are warning signs)

A small leak isn’t a minor thing; it’s a sign the water has found a path into your structure. Delaying repair lets moisture damage accumulate, potentially harming sheathing, insulation, ceilings, and framing. If you notice a new stain, missing shingles after wind, or granule loss in gutters, schedule an inspection. Quick, targeted repairs are almost always less expensive than waiting until a replacement is required.

Choose contractors who train their crews and document work

Experience counts, but the best companies combine experience with continuous training, clear paperwork, and strong warranties. We invest in in-house training and use documented installation procedures, so every crew installs to the same high standard. Ask potential contractors about training, references for local jobs, and whether they can show you past projects in your neighborhood.

Preventive maintenance saves money every time

Finally, think of your roof like a car: routine maintenance extends life and prevents emergencies. A neighborhood storm, heavy snowfall, or a season of ice can accelerate wear but regular inspections, attic attention, gutter care, and timely repairs will protect the investment in your home’s roof.

If you’re in Mount Prospect or the northwest suburbs, our recommendation is simple: schedule a professional roof inspection at least once a year, clear gutters in the fall and early spring, and call an experienced local roofer for any red flags. We’ll walk your roof, explain what we see in plain language, and give you options that make sense for your home, not for our schedule.

We’ve been in your neighborhood for more than four decades. Our crews are trained, licensed, and local. We know what Chicago winters, spring storms, and seasonal temperature swings do to roofs and we’ve learned how to stop those problems before they become disasters. If you want to protect your home the way we would protect our own, start with a seasonal inspection and a whole-system approach. That’s what 45 years in roofing has taught us.
