A pitched roof is a roof with a slope, or incline, that allows for drainage and runoff. A flat roof, on the other hand, is characterized by a horizontal or nearly horizontal surface. Since water drains poorly from a flat surface, flat roofs are more susceptible to ponding water and leaks. For this reason, it is often necessary to replace a flat roof with a pitched roof.

If your flat roof is damaged or leaking, replacing it with a pitched roof is a good option. Pitched roofs are more durable and can last for many years with proper maintenance. To replace your flat roof with a pitched roof, you will need to:

1. Remove the old roofing material and any damaged insulation.

2. Install new rafters or trusses to support the new roof.

3. Cover the new rafters with plywood or OSB sheathing.

4. Install new roofing felt and shingles.

5. Install gutters and downspouts to protect your home from water damage.

Which roof is better flat or pitched

There are a few things to consider when deciding between a pitched roof or a flat roof for your home. Pitched roofs are more suitable for wetter climates and can resist moisture damage better, but they may not be as aesthetically pleasing as a flat roof. Flat roofs are more appropriate for areas that receive little rainfall and can be easier to maintain, but they may not be as durable in harsher weather conditions. Ultimately, it is up to the homeowner to decide which type of roof is best for their home.

There are several reasons that flat roofs are more likely to leak than sloped roofs. One reason is that flat roofs are not as able to shed water effectively. In other words, water does not slide off them as easily as it does off of sloped roofs. This can cause the water to build up on the roof and eventually leak into the building. Another reason is that flat roofs are more likely to have seams and cracks where water can enter. Finally, flat roofs are often not as well-constructed as sloped roofs, which can also lead to leaks.
