The HPC will consider new technological advances on a <br /> 3 case-by-case basis. <br /> 4 <br /> 5 <br /> 6 Rooflines and Roof Details <br /> � The roof is another key visual element on a building. The angle of the roof pitch <br /> 8 and the height of the roof from the ridge to the eave have a substantial impact on <br /> 9 the appearance of a building. Pre-Civil War houses typically have steeper roofs <br /> 10 than twentieth-century houses, for example. The character of the roofline (such <br /> 11 as an enclosed boxed-eave with fascia trim, gable-end returns, or an open eave <br /> i2 with exposed rafter ends) provides information about the building and its period of <br /> 13 construction. Contractors often cover or remove these character-defining features <br /> 14 during the application of replacement siding (vinyl or aluminum). Proposals to <br /> 15 change roof pitch or remove trim will be discouraged. Proposals to add excessive <br /> 16 roof trim inappropriate to the date of the house will also be discouraged. When <br /> 17 constructing additions to local landmarks or contributing buildings in local districts, <br /> is or when constructing new detached buildings, the new roof pitches should be <br /> 19 compatible with the old roofs. <br /> 20 <br /> 2i Chimneys likewise contribute to the character of historic buildings. Many Orange <br /> 22 County chimneys were constructed with local stone for the base and brick for the <br /> 23 stack. Others display decorative brick corbelling at the top. It is important to <br /> 24 retain existing chimneys in their original condition and location. When a new <br /> 25 chimney is required for mechanical systems, it should always be simple in design <br /> 26 and should be positioned where it will not visually compete with any historic <br /> 27 chimneys. <br /> 28 <br /> 29 <br /> 3o DESIGN STANDARDS for Rooflines & Roof Details <br /> 31 <br /> 32 III-C-15. The original roof pitch and the ridge height should be retained. The construction <br /> 33 of any new dormers or skylights should not be visible from any public road and <br /> 34 should be on the least visible sections of the roof from within the property <br /> 35 boundary. <br /> 36 <br /> 37 III-C-16. All chimneys should be preserved and repaired using the same material, patterns, <br /> 3s and methods as the original construction. New chimneys should not visually <br /> 39 compete with original chimneys. <br /> 40 <br /> 41 <br /> 42 Other Important Visual Features <br /> 43 Details such as Italianate brackets and Craftsman-influenced triangular <br /> 44 kneebraces are important character-defining elements. Such details are often <br /> as removed with the application of synthetic siding making the exterior of the house <br /> 46 appear over simplified in design. The combination of new siding with a different <br /> a7 type of siding exposed to the weather and replacement windows with different <br /> 4s muntin sizes often makes a building appear light-weight and out of proportion. <br /> 49 <br /> 5o The HPC will not deny a COA based on a proposed color palate. HPC members <br /> 51 may comment that a proposed color scheme seems out-of-place or that a <br /> 52 proposed paint scheme seems too busy. Paint is an important part of building <br /> s3 maintenance and the HPC encourages property owners to paint their buildings at <br /> 54 regular intervals to protect the exterior siding and trim.
