"Water started leaking from a bedroom ceiling… Even though the leak was probably coming from the chimney flashing, I knew the roof was old enough for replacement. Based on their stellar reviews and clean record with consumer affairs, I called Four Seasons to make an appointment and get an estimate for repair or replacement. Although it was Dec. 31, Bill showed up on time, something I have found lacking with other construction people over the years. He was cordial and knowledgeable, and not aggressively pushy. I felt comfortable. Having done my own research, I found his price to be reasonable, not the cheapest or the most expensive. My main interest was workmanship quality and over the years have found cheapest is not usually the best, nor is most expensive. His crew arrived within 10 days, and on time. Their work was one of the most professional I have ever seen. In fact, when they were finished, my property was cleaner than when they started. After they left, you wouldn’t even know they were there. The leak is repaired and the new roof is beautiful. I highly recommend them."

"We were extremely happy with the job from start to finish. Rapid Roofing was very professional and used the highest quality of Owens Corning materials. Along with a 50 year warranty from Owens Corning helped to seal the deal. They replaced the entire roof on our house and garage, also replaced facial and gutters in both. I give the job a 5 star rating"

"This was the best experience I have ever had dealing with a contractor. Jacob and his team went above and beyond my expectations. Jacob was able to stay within our budget. Cost that was estimated is what was invoiced at the end of the job. We started off with just getting our roof replaced but then decided to put a new roof and siding on our garage. Everything was done within two days. Left the outside of our house spotless. I recommend JI Roofing to everyone that needs to get their roof and or siding done."

"Nonstop home improvements were great! They were recommended to us, and I would highly recommend them as well. They thoroughly took care of us, addressing any concerns we had and made the roof replacement easy. They tore up two layers of shingles, replaced the wood underneath and layered new shingles. All for a fair price!"

"Brian Nela [Alsideconstruction] 10/29/2022 2:42:00 PM Brian Nela and a family member as an assistant arrived a little late due to auto and ferry traffic. No big deal. [Normal for the east end of long island.] <><> THE Work ethic was outstanding: (a) explained all work, (b) answered questions, (c) made sure I knew what was going to be done: including the materials to be used and the quality of the materials to be used. In addition, The work was not JUST a repair, it was the installation of a new flat roof over a two-car garage, which necessitated (1) removing the decking, and placing it on the patio (neatly!); (2) removing the stringers, cleaning all debris that lay beneath the decking, including rotted stringers, with nailing to be removed, and biological debris from leaves, tree seeds, etc, (3) power washing the top of the base roofing that will remain, epoxying all rows of nail holes on the 20x17 roof, laying a base epoxy coat prior to installing the new roofing fabric. <><><> In addition, Brian cleaned the chimney from my wood-burning stove, surveyed the roof and the flashing around two chimneys, and found the flashings in need of replacement, those flashing were also repaired. <><> Finally, one section of siding on the second story was replaced with a matching sheet of asphalt shingle. For the future: a new roof for the house is under consideration. ***** Brian Nela [Alsideconstruction] is highly recommended."

"When I needed a new roof, I called Jake. He handled everything from beginning to end. I received an estimate immediately, and a crew was on site in no time. The crew was neat, fast, and thorough. When they were done, you couldn't even tell someone was there...other than the amazing looking new roof! I highly recommend Jake and his team!"

FAQs for asphalt shingle roofing installation and replacement projects in Greenlawn, NY

Roofing professionals can usually install a medium-sized asphalt shingle roof in two to three days. Installation time increases if your roof is particularly steep or difficult to access or has features like chimneys or skylights that roofers must work around.

Three-tab asphalt shingles usually have the lowest upfront cost of any roofing shingle material. They’re sturdy and typically last 15 to 20 years. However, they may have a shorter lifespan in especially hot or cold climates. Talk to a local roofing professional about the best materials for your climate. In some cases, materials with a higher upfront cost may save you more on repairs or replacements in the long run.

Start by multiplying the length by the width of your roof to calculate the square footage. Most shingle replacement costs $4 to $12 per square foot for materials and labor, depending on factors like the material and the slope of your roof. Once you know the size of your roof, you can calculate a rough estimate of total costs or contact a local roofing professional to provide you with a custom quote.

Asphalt shingles are generally considered to be a low-maintenance item. However, cleaning your asphalt roofing can help prolong the lifespan and keep it looking fresh. If you’re comfortable with DIY and have the proper equipment, you may be able to clean your asphalt shingles yourself. However, if you have an especially high or steep roof, it’s usually safer to hire a professional roof cleaner.
