"Geno's Siding and Roofing, LLC provided a very competitive price for my gutter install project. My project was unusual that my home required the replacement of several sections of extremely long gutters, which they installed with ease. The professionalism and the quality of the work that Geno and his team performed surpassed my expectations. I plan to engage Geno's for additional projects in the very near future."

"Denny the salesman was very nice and explained clearly everything that would be done. The crew arrived on time and finished the job in about 5 hours (roof installation). They did a great job and cleaned up nicely. The next day the gutter installation was done and it was done very well also. I would recommend Nu-Look Distributors for a roof installation."

"If you are looking to have a roof replacement, Top Roofing is the company to choose. The crew did a beautiful job installing my roof. They arrived in the morning, tarped and moved everything to ensure no damage to bushes, patio furniture, etc. The job was completed the same day which was pretty amazing. The team cleaned up and put everything back to where it belonged. Such a wonderful experience! A big thank you to Top Roofing!"

Roofing FAQs, answered by experts

Yes, a roof blister can cause a leak if it gets to the point where it pops. Prior to popping, a roof blister is just an aesthetic issue, but once it pops, you’re left with a small hole in the shingle. Water from rain and snow can easily get inside this hole and interact with your underlayment, roof decking, and the building material below.

There are several pros and cons of flat roofs. One disadvantage of flat roofs is that you lose potential attic space because it's flat. Flat roofs tend to pool water and because they lack an angle, any leak in the roof—usually due to a bad seal—has the potential to let in a lot of water. They don’t work well in climates with snow. Flat roofs are also structurally weaker than sloped roofs.

You can replace a roof in the winter, though it’s not the most popular time to do so. The biggest drawback of winter roofing work is the weather. Snow and ice make for dangerous, slippery working conditions. Plus, shingles can only be installed in temperatures above 40 to 45 degrees. 

The best time to replace a roof is in the spring or fall when the weather is mild. However, you can likely save some money by booking the job in the winter off-season, when roofers have more availability. 

A few disadvantages of installing solar panels on your roof include the high up-front costs and the potential for increased property taxes. Installing solar panels can increase the home’s value, which in turn can mean higher taxes. Depending on your area, you should check with your local tax offices for more information. Another potential pitfall is roof leaks from a poor installation, but this shouldn’t be an issue if you hire a reputable company.

Rain shouldn’t come in through your ridge vents unless your vents are damaged or the rain is accompanied by very high winds. Most ridge vents use flashing or baffling to keep out rain, snow, and debris. If your ridge vent isn’t baffled, rain is more likely to enter your attic, so ridge vents with baffles are a better choice in areas with regular rainfall.
