About Klaus Larsen: Klaus Larsen bought his first apartment building in Denmark at the age of 21, renovating every single one of the 13 apartments in it in less than three years. At the age of 32, he immigrated to the US with his tools and $300 in his pocket to live the American Dream. Little did he know those metric tools would do him little good in a country that only used inches and feet. By 1998 he was able to start his own home improvement business, becoming a roofing-only company in 2010. Klaus is well known for his historic work, using his ingenious creativity to update antique homes so their roofs perform properly while maintaining their architectural integrity. His attention to detail and Old World craftsmanship have earned him a reputation for helping to maintain New England’s rich history while integrating state-of-the-art roofing technology into it’s homes.

"Team (from Anthony the estimator to the install crew) was thoroughly professional. Communication from the company was excellent. Updates on schedule were frequent. Project started on time and completed true to the quote given. Not the cheapest quote we received (nowhere near the highest either) but certainly a good value."

Roofing questions, answered by experts

EPDM roofing is a single-ply roofing material made of rubber, and a professional will install it in a single sheet and seal the seams. Built-up roofing (BUR) consists of multiple layers made from asphalt, adhesives, and roofing felt. A professional will construct the layers of BUR on-site. EPDM is easier to repair and has better resistance to extreme temperatures, while BUR is more fire-resistant and affordable.

Flat roofs are cost-effective, offer usable space, and are easy to maintain. Foam and single-ply materials provide excellent insulation and durability.

Complete house winterization goes above and beyond the list we created above. In addition to everything listed, full house winterization also includes:

  • Performing a home energy audit.

  • Preparing your deck and patio for winter.

  • Learning how to start a snowblower.

  • Replacing smoke detector batteries.

  • Installing outlet gaskets.

  • Installing storm doors.  

The best style of chimney cap for a brick chimney is one that fits tightly around the brick top of the chimney. The cap should have a screen to fully enclose it to keep animals out. The best materials include stainless steel, copper, or aluminum that fit tightly or are custom fabricated for a perfect fit on your chimney.

The materials that make up your roof will determine how long your roof will last. Typical three-tab shingles generally have a life span of about 20 years, while architectural shingles can last up to 30 years under proper maintenance. Metal roofing materials have longer expected life spans, starting at around 40 years. They can sometimes last up to 100. Slate roofs can last 150 years or longer with proper care.
