I've never seen employees work so hard it brought tears to my eyes lol. I then had Lecla paint the exterior of my home.

They sanded my house to the bone fixed all the rotted shingles primed and painted all in FOUR DAYS! They are THE MOST efficient company. Don't look anywhere else this is the place!"

Licensed and insured roofing company and exterior contractors serving Westchester County, NY and the surrounding area. We are full-service contractors for residential and commercial roof replacement and repair, new roof installation, chimney repair, skylight installation, siding installation, windows, and doors. What sets us apart from the other exterior contractors? In 2012 we decided we’d ditch the sales gimmicks. Instead, we aim to be your most trusted exterior contractors by building strong relationships with Hudson Valley homeowners. By focusing on educating our customer, we ensure you have a quality exterior contractor work on your project, even if it's not us you hire. As your neighbors, we want to earn your trust and build relationships that last a lifetime. We believe an educated customer can make better decisions, knows what to expect and is better equipped to manage residential roofing and contracting projects in the Hudson Valley.

We are your elite roofing company, but don't just trust us, make us prove it!

"I have worked in construction my whole life. MCAS did a nice job in a timely and efficient manner. It came down to two comparable bids but I chose MCAS because it's a family run business and I could call Mike, the owner of the company, any time and he would answer. You also have to admire a roofer who breaks off and starts his own company. I have a soft spot for those with an entrepreneurial spirit, improving the US economy. Justine was also exceedingly pleasant to deal with. Responsiveness ranks as my top priority when dealing with large home projects and Justine get full marks, always getting back to me within minutes. They didn't try upsell me or talk me into any extras, they did exactly what I asked for in a quality manner and at a competative price. The crew was friendly and fast.

"As an environmentally conscious household, it was important to us to hire a service that used neither harsh chemicals, nor bleach products for roof cleaning. I previously received Roof Renew Pros’ mailer and held onto it for this occasion as we had gotten moss and lichen growth on our roof. I kept the mailer as it stated their use of organic products, as well as no pressure washing, which was very important to us. After reading reviews, we decided to call RRP. Barbara came and inspected our roof, explained what was growing on it and took photos for us to see what was going on up there. There was more moss on our roof than we had initially thought. Barbara went over the process, what would be done on the day of and next day, gave us the price, so we booked our cleaning. The RRP crew arrived on the day, cleaned our roof in a timely manner and applied a sealer to prevent new growth anytime soon. Our roof is now lichen/moss-free and winter ready. It looks like it did when we first moved in. The crew was thorough and very helpful. The price fell within what we expected to pay for such a service and the fact that RRP use organic products, was HUGE to us. We’ll definitely use RRP in the future and totally recommend this company for your roof cleaning! Quality and eco consciousness matters to us, since our home is our biggest investment."

We service lower Fairfield County, CT and parts of Westchester County, NY. Brian’s career in the pest control business began over 25 years ago. He spent three years in the southern United States learning from a world-renowned entomologist (among others) and helped start the Sentricon baiting program for termites with Dow Elanco. Brian advanced through the field to eventually run a major sales force and acquired a distinctive edge in the business. Through this experience, Brian realized he wanted to return to his home state of NY and create his own niche in the rodent control market. He developed a highly successful approach, rejecting the easy but environmentally unsound approach of poison – and instead relying on hard work, common sense, and the correct materials to prevent rodents from entering people’s homes in the first place. Fast forward a few years, and Brian began to realize there were additional niches in this area that needed to be more friendly towards the environment and the clients’ health. He therefore co-invented the Enviroboot® Dust Suppression System to help control the toxic silica dust that is produced when concrete is broken with a jackhammer.

Roofing questions, answered by experts

You can damage your shingles if you use the wrong type of paint on them. You should always use acrylic latex paint specifically formulated for shingles. Other types of paint may trap moisture, which can cause bigger problems like rot and mildew. Considering that roof replacement costs $9,100 on average, it’s definitely best to avoid making this mistake.

Besides using the right paint, remember that painting your shingles will require increased maintenance.

An impact-resistant roof can last between 30 and 50 years, depending on how much wear and tear it receives.

Unlike wood decks, Trex decking doesn’t warp. That’s one of the key benefits of installing this decking material. Over time, common issues with these decks include hard water stains, mold or mildew growth, and stains from food spills. Thankfully, with proper cleaning, you can get rid of most stains and mold.

How much snow a roof can handle depends on the snow’s weight and the roof's strength. Wet snow is far heavier than dry snow. In areas that receive annual snowfall in abundance, house designs regularly allow for between 35 and 50 pounds per square foot, equating to up to four feet of fluffy-snow accumulation.

Wood shake roofs are durable, energy-efficient, and offer a natural aesthetic. Composite options provide similar looks with less maintenance.
