Installing a full roof on this Victorian house in Willimantic was a great honor and privilege for us. The complex style of architecture along with the turret required a highly proficient roofing company, and we were happy to oblige. All of the plywood needed to be removed and replaced, as part of a complete overhaul. We've worked on residential turrets before, so we were prepared with the experience needed to effectively roof a conical structure in a timely and proficient manner. This job had a remarkable outcome and the home is a lot closer to being fully restored. It is one more piece of Connecticut history that we have both protected and rejuvenated.

Here was a Willimantic Victorian, with two apartments under one roof. Tenants were experiencing some leaking, and the landlord called Klaus Larsen to determine the cause of the problem. We consistently advise staying away from using 3-tab shingles, which lay side by side and are non-dimensional. They typically blur the line between an inexpensive and 'cheap' product. This roof was replaced with Duration architectural shingles, with Mule Hide purpose made flat roofing on the front shed roof deck.

Recent damage after snow storms. Initially noticed as damaged plaster in second floor bedroom ceilings. A section of plaster fell to the floor in one bedroom. Water spots in second bedroom. Both at front of house. Ice dam suspected. Some snow removed and roof tarped. Would like a second estimate for my insurance company and to have work completed as soon as possible. Damage was initially noted on 1/29. Roof tarped on 2/1. I live in NH and am renting my house in Willimantic. Hope to hear from you soon. Kathy
