"David and his crew are amazing! They really know their "stuff". We have a 10 unit condo complex surrounded by lots of trees. Last year they did dry rot repairs, fixed or replaced gutters throughout the complex. It was quite the project! In the fall, we hired them again and they did a gutter cleaning. They really did an outstanding job on both projects. Recently, they cleaned our gutters again and fixed 27 end caps. David's team did an excellent job and even cleared away the leaves in the complex. They take pride in their work, which is a rare thing today. We really appreciate the wonderful customer service and personal touches through phone calls, texting and emails. They are quick to respond, professional and friendly. All the residents were very impressed with the work they did. Because of the fair prices, easy to work with, and always doing a fantastic job we would not hesitate to use them again. Within 5-7 years we will be looking to them for new roofs and to install the GutterHelmet System. As the treasurer of our HOA, along with the other officers, we highly recommend this company."

"Steve from Smart Roofing Systems was amazing! As soon as I submitted my request he gave me a call with pricing and scheduled an immediate appointment. He knew immediately what the cause of the roof leak was. He is extremely knowledgeable about roofs and gutters. His prices are fair and his service was very timely. He definitely saved me from a major disaster. Within two days of his repair to my roof we we had two major storms. Half of my home would have been flooded! Many, many thanks to Steve Gubera from Smart Roofing Systems!!!!"

"Rocky and his team were professional, fast, and cost-effective! We had a three-car garage that we wanted to get professionally epoxy coated as I run a small business detailing cars out of it. Rocky came by the same day to provide me with a quote and was able to get the work done the next weekend! The pricing was competitive, the quality was top-notch, and now my garage looks like a professional auto body shop!!! He was also super knowledgeable and the materials and the prep and gave me suggestions on what type of material would work best in my application. Since he has experience in the commercial space, none of the material was that home Depot garbage that delaminates in a year or two. Everything was commercial grade and has a great warranty. I highly recommend him for any type of epoxy floors!"

"Pablo and his crew know what they're doing. Our standing-seam metal roof looks great! They showed up on-time every day, worked hard, fixed problems that were discovered and left us with a beautiful roof. It was obvious from their bids that many other roofing contractors didn't really want to install metal. Ontop gave us a fair quote - and backed it up with great workmanship."

Roofing FAQs, answered by experts

No, you should not close or cover your gable vents in the winter. While it might seem logical to block cold air, heating your home creates hot air that rises and can cause condensation in the attic. If the vents are covered, this moisture becomes trapped, creating an ideal environment for mold and mildew. Keeping the gable vents open ensures proper ventilation, which helps dry out the attic, maintain even temperatures, and prevent moisture-related damage.

Generally, roof flashing is installed under the shingles to create a watertight seal and prevent moisture from seeping in and causing damage. However, the exact placement can depend on the type of flashing. For instance, with step flashing, the shingles and flashing overlap each other, meaning the flashing is technically both over and under the shingles. Flashing also typically goes beneath the house siding and is often not visible from the ground.

Hail is unlikely to damage a tar and gravel roof because the hailstones will hit the protective gravel rather than your delicate roof membrane. A tar and gravel roof is the most resilient flat roof option, which means it’s the best one for areas that see hail, fallen tree debris, and blown debris from intense winds.

Asking questions before hiring a roofer ensures you receive the best quality for your investment upfront and in the long term. Roofers with minimal experience, unfamiliar with local building codes, or minimal access to great materials can lead to both structural and financial problems down the line. You should also be able to easily communicate and collaborate with your roofer during extensive projects.

Hiring a reliable roofing contractor requires finding a company in your area with years of experience, holds the necessary licensing, and has a history of positive customer reviews and services. Start by researching whether a roofer you’re considering hiring holds the necessary certifications. Consider requesting customer references from your top contenders. Finally, get quotes from a few roofing companies and decide which provides the best value overall.
