Flat rooftops are common in industrial buildings but uncommon in commercial structures except where space is limited, such as warehouses and carports. They allow large areas covered by a single surface without structural support for vertical loads. A problem with flat roofs is that the surface area may collect rainwater as runoff if there are problems in water drainage.

Flat-roofed houses sometimes have their roofs changed to a steeper pitch, making them more able to drain correctly and shed snow accumulations effectively. The main reason behind this conversion is ice dams caused by melting accumulated snow on sloped rooftops during cold spells – leading to leakage into houses below, which can create significant damage over time or flooding when it fails catastrophically. Another common cause for roof pitch change involves basements used as living space with low ceilings under steeply pitched roofs, where there is inadequate headroom at standard seated height.

Flat extensions are created by adding a new floor to the top of an existing building. This type of roofing service is often used in basements that are low ceiling height or where large windows need to be placed on roofs for better views and light.

Installing a brand-new roof can come with numerous benefits, such as making your home more energy-efficient, creating space for solar panels if desired, plus helping keep out moisture which could lead to rot or mould infestations inside walls long term – resulting in added health problems over time.

Chimneys are the most vulnerable part of your home’s exterior, as they can be damaged by heavy rain and high winds. It is critical to ensure that ice dams do not form on top of this structure or that structural damage occurs due to erosion or water infiltration leaking into the insulation layer between bricklayers.
