"I contacted M and J roofing about a leak. Lous response was quick and after inspecting my roof responded with urgency. I had many roofs installed over the past several years none of which seem to work due to the pitch. The most recent roof I put on was a metal roof, which was the source of many of the problems. After Lou inspected it he told me what needed to be done and after agreeing on the contract he started immediately. They are prompt and professional and both him and his son Nick are two of the kindest human beings I ever met. They told me they'd be here at 8:00 a.m. and they were here before that, they started at 8:00 and we're done by the end of the day. Lou and Nick kept me posted each step of the way and during the removal of the metal roof they showed me what went wrong and explained why it went wrong. In short it was because of companies or people that install roofs that don't care about their work that care about ripping off unsuspecting customers. That is why in closing I will say M and J roofing should be the only and I am stressing only company anybody should want to do any work on their roof."

"It was awesome. Someone had recommended this company to me and they were great. It snowed about a foot the day before and they showed up with about 10 guys and shoveled off the roof! They had the roof completed within a day. They came back the day after (which was a Sunday) to do a second walk through and to ensure everything was cleaned up. I would highly recommend them to others."

"Roof Systems is amazing ... they are the Superman of roofing. Our home sustained serious roof damage caused by a tropical wind storm. Roof Systems came out the same day to access the damage and then placed protection so our roof would not sustain more damage or create internal damage to our home. Their work is always done with pride and a high standard of perfection. They are always professional and friendly. I will only allow Roof Systems to handle our roofing needs."

"Mighty Dog Roofing have such a high bar! We appreciate the amazing transparency and integrity throughout the whole procedure of our full roof replacement from beginning to end. The end result is a stunning and sturdy metal roof. Big shout out to Tom for making me understand the pros and cons between asphalt shingles and metal roofs. The drone superscan was also very cool!"

Roofing questions, answered by experts

Fall is widely considered the best time of year to replace a roof. The moderate temperatures are ideal for roofing crews to work and for new shingles to seal properly. Additionally, autumn weather is often drier, reducing the risk of weather-related delays compared to the rainier spring season.

While spring is also a viable option, the higher chance of rainfall can slow down the project. The main drawback to a fall installation is that it's the peak season for roofers, which can lead to higher prices and scheduling challenges.

To potentially save money, you could consider scheduling your roof replacement during the summer or winter off-seasons. However, both seasons have significant disadvantages. Extreme summer heat can make shingles too soft to handle, while winter's cold, snow, and ice can create dangerous working conditions and prevent shingles from sealing correctly, as they typically require temperatures above 40-45°F.

In some cases, yes, you can put a second roof layer over architectural shingles, but it depends on your home’s structural stability and the local building codes where you live. Architectural shingles are thicker and heavier than standard asphalt shingles, so you may need structural reinforcement or a structural engineer’s inspection before proceeding. Additionally, some building departments don’t allow for two roof layers, regardless of the roof type. You should ask a professional if ripping the old roof off before installing the new one is the best option for you.

Gaps between tiles are necessary to help with weatherproofing, allow for thermal expansion, and increase wind resistance. In general, a small gap no larger than 3 millimeters wide will encourage proper drainage and limit cracking. Beyond that, tiles should overlap a minimum of 3 inches, except at the eaves where they should extend to the center of the gutter.

A roof pitch multiplier is an accurate way to calculate roof square footage, and it’s handy for purchasing the correct amount of materials. To determine your roof pitch multiplier, you'll need to calculate the roof slope, square it, and add it to 144. Next, find the square root of the total and divide it by 12. The answer is your roof pitch multiplier. Once you know the roof pitch multiplier, multiply it by the total square feet of your building to determine the total roof surface area.

Yes, gable vents can let water in. That being said, this usually only occurs during extreme conditions like heavy rainfall. You can prevent water from entering through gable vents by adding a screen that traps the water before it can enter.
