Here are some reasons why a sloped roof is the better choice
Roofing experts and professionals highly recommend the use of sloped or the more popular term, pitched roofs. This is due to the fact that they last longer. How much longer? 20 to 50 years longer! Just ensure it's made with asphalt shingles or metal shingles. On average, a flat roof will last only up to approximately 10 years, which is a whole lot less than the 20 year minimum attached to a sloped roof. This brings us to the long-term costs.
Now most of us have seen an increase in snowfall and rainfall on our weather forecasts, which can potentially cause structural damages overtime. As a result, you'll be paying yearly roofing inspection costs to ensure no structural damages. It may be more than yearly!
On the other hand, sloped roofs are designed with the intention of letting rain and snow run and slide right off. Hence the name pitch roof. It's the pitch, that helps to reduce the amount of weather beatings and minimizes the potential for structural damages overtime. That said, you won't be paying any yearly additional costs.
Why Risk Leaks?
From experience, having a leaky roof is annoyingly frustrating. A flat roof will capture snow and rainfall, even if designed with a slight slope. Overtime this water storage will build up and form water puddles and ponds, that will cause leaks eventually. Water build up can also lead to mold and moisture damage to your flat roofing structure, and can lead to your roof collapsing.
Won't Drainage Systems And Sealants Work?
Water drainage systems can become blocked by all types of debris, especially during fall. Leaf guards will help to an extent but won't prevent blockages. Take it from us, as we've learnt this the hard way. Slapping on a coat of water resistant sealants on your flat roof won't entirely rescue it either. There is a very high possibility that your roofing sealant may be uneven or become undone. So home designers, when opting for a flat roof, ask yourself if all the glam and glitter associated with this roof type is worth all the long-term financial risks attached.
