Job Stories From Hartford, CT
Slate & Flat Roof Replacement in Hartford, CT

This extensive job was one that took time, attention to detail and professionalism. What started as a routine roof replacement turned into a bit more of a project. As we tore off the existing roofing material, we found a slate roof under a layer of existing asphalt shingles. This was unexpected, but nothing the Klaus Larsen team couldn't handle. After finally tearing off both the slate and asphalt, we replaced all damaged sheets of plywood decking, installed an ice & water barrier as well as flashing tape on all roof joints. We installed the IKO Cambridge Architectural Shingle in the color Charcoal Grey. 

There was a flat section on the low slope of the rear addition of the roof that was also to be replaced, however, we were to complete this part of the project in the spring, due to installation temperature constraints. Once it was warm enough out this spring to install the rolled roof, we installed a complete two-ply Owens Corning DeckSeal Modified Bitumen Rolle Roofing system. 

This house is now safe, secure, and looking better than ever thanks to Klaus Larsen Roofing!

Asphalt Roof Replacement in Hartford, CT

This home in Hartford two types of roofs: It had asphalt shingles on the main house and two small flat roofs attached towards the front. During our inspection of the roof, the owner pointed out several areas of concern. The gutter on the rear of the house was damaged and the fascia boards on the flat roofs were rotting away. The customer was very happy with the work we proposed and was able to do the project through our financing option. 

When we came to replace the roof, our crew stripped the entire roof of asphalt and flat roofing. We then replaced 5 sheets of plywood before installing 9 feet of Ice & Water barrier. Next, we installed DeckSeal Flat roofing on both flat sections. We replaced the damaged gutter in the rear with new aluminum seamless gutter with LeafRelief gutter guards. We tore out the rotten fascia boards are replaced them with new pine trim boards that were then wrapped in aluminum. The entire process of tearing off the old roof to installing the last piece of chimney flashing took 1 day to complete. The entire property was also cleaned up and the roof is protected by our Owens Corning Platinum Warranty.

Dutch Colonials of Hartford County

We love roofing in Connecticut because this state is such a treasure trove of historical architecture. The homes we encounter bring together styles from all over the globe and our neighborhoods are truly a melting pot of the varied design virtues brought by over by ancestors.

One design in particular is the Dutch Colonial. These 'barn houses' are built with wide gambrel roofs to have increased attic room. You'll often see decorative or arched brackets, double-hung windows and clapboard siding. Another common trait of Dutch Colonials are gable-end chimneys, as seen on this Manchester, CT property.
