The concept of home improvement, home renovation, or remodelling is the process of renovating or making additions to one's home. Home improvement can be projects that upgrade an existing home interior (such as electrical and plumbing), exterior (masonry, concrete, siding, roofing), or other improvements to the property (i.e. garden work or garage maintenance/additions).
The roof, the top covering of a building, is one of the universal structures found on all buildings. Its purpose is primarily to shed water off the building and to prevent it from accumulating on top. To achieve this goal, roofs may be highly pitched (sloped) or low sloped in form. Low sloped roofs are commonly found on industrial/commercial type structures. Pitched roofs are the primary design found on residential homes. Metal standing seam roofs are becoming increasingly common on low sloped roof assemblies. Cool roofs and green roofs are becoming increasingly popular, and in some cases are mandated by local codes.
Residential roof designs in mild climates or where there is little precipitation tend to exhibit lower pitched roofs and drainage at the exterior wall; an example of residential flat roof is that of the adobe construction in the American Southwest. In northern climates, where temperatures drop below freezing, or in southern climates with high temperatures, the need for greater thermal resistance will dictate the type of roof design as well as the waterproofing membrane specification.
Bad financial investments caused the Twain family to move to Europe in 1891. When they returned to Connecticut in 1900 he lived in a house built for him in Redding, Connecticut,named Stormfield, where he died on April 21, 1910. His home in Hartford functioned as a school, an apartment building, and a library after that. In 1962 it was declared a National Historic Landmark. Since 1974 it has had a multi-million dollar renovation and an expansion dedicated to showcasing his life and work.
