Hardie shingle siding installed, with new aluminum soffit/facia. After siding removal we agreed the roof was toast, and they threw a new one on quickly. The house looks great, and owner Gordo is quick to return calls and get any issues resolved promptly.

Roofing questions, answered by experts

Yes, Energy Star roofs are one of the best types of roofs for cost efficiency. They can reduce your peak cooling demand by anywhere from 10% to 15%.

Common problems include loose or missing shingles, leaks, and weather damage. Regular inspections help prevent major repairs.

Roof sheathing can buckle from moisture damage, too much weight from roofing materials, or too much space in between rafters without thicker sheathing to compensate for the added distance. Bucking roof sheathing is a serious problem that can lead to a collapsed roof, so have a qualified roofer near you come to identify the problem as soon as possible.

If the bay window extends beyond your existing roofline, you must add a roof or a small “skirt” to divert storm water and prevent water damage. The window roof can match your existing house roof, or be finished with copper or other decorative materials. Most bay windows have a roof with complete flashing regardless of their placement to prevent leaks into the home.

Metal roofing offers durability, energy efficiency, and resistance to extreme weather conditions. It can reduce cooling costs, has a longer lifespan than traditional materials, and provides a sleek, modern appearance, adding value to a property.
