"Both the owner of Guardian Roofing Systems, LLC, Angelo Ristich and his Lead Repairman Hector were professional and very knowledgeable about the task at hand and what needed to be done. They answered my questions and made sure I had full understanding of the whys of the roof replacement. I was quoted a fair price. The job was completed in a timely manner and true to their word, when the next heavy rain high windstorm happened the new roof held up beautifully. The leaks my house was plagued with aren't a problem anymore. For quality service at a fair price I definitely recommend them."

"Initially, I thought it was fine. However, I was very curious why the contractor would not let me talk to the insurance adjuster. He told me to stay in the house and leave everything to him. (RED FLAG) I'm not sure why I let that happen. After the negotiations and the contract was signed, the contractor advised that he failed to charge me for the cost of the chimney. We specifically talked about the chimney cost and how he wasn't putting it in the contract so it wouldn't alert the insurance company (RED FLAG ) He would just charge me another $1200 for the chimney or not do the inside work. At that point, I should have cancelled the contract. The contractor yelled at me that he forgot and he made a mistake. Yelled at me in a very loud voice. He then did that "used car" sales pitch where he has to go talk to his boss and then comes back and sends me an email that they will fix the chimney for free. I spent about twice what my budget was, and I really am mad at myself for failing to get other estimates. That is on me. The roofers put a new roof on - my old roof was less than 5 years old - not sure if a simple repair would have been okay and left a mess in my yard. There was debris from my gutters and little blue things that they use when they replace a roof. I told the contractor that, and he said "the roofers don't make money if they clean up after the gutters and feel it's not their job". Okay, whose job is it? Who did I pay to do a job? Am i supposed to hire someone else to finish up what the roofers left behind. My pet peeve is when I pay someone to do a job, and they don't finish the job and say it's not their job. That makes me so angry. Again, I'm so mad at myself. I know better. I just felt like at the end of the day I was taken advantage of. I don't think I needed a whole new roof, I spent twice the money I had budgeted, and I had a mess to take care of. I use Angie's List so I can avoid being taken advantage of and considered the "old lady" who doesn't know anything."

Roofing questions, answered by experts

While a few icicles on your roof are standard, a large accumulation can be a sign of a bigger problem, such as poor insulation. This is particularly true if you are also dealing with ice dams. If you have numerous large icicles, it is recommended to have a roofing contractor diagnose potential insulation issues and create a plan to solve them.

A gambrel roof and a mansard roof are similar in that they are both hipped roofs, meaning they have double slopes—one steep and one more gradual above the steep slope. The difference is that a gambrel roof has a double slope on only two sides of the structure, whereas a mansard roof has a double slope on all four sides.

Ridge vents can last as long as your roof does. As long as your ridge vents were installed correctly by a qualified professional, they will need very little upkeep. Inspecting your ridge vents annually to ensure they aren’t cracked, clogged, or leaking will help prolong their lifespan. 

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.

Asphalt shingles, wooden shakes, and slate or clay roofing tiles are often replaceable without having to replace the entire roof. It's possible to replace just a few shingles or tiles without much trouble in the case of wind damage or other minor problems. DIYers can perform the task in some situations. However, professional repair is always the best bet when it comes to roofing.
