Higher roofs are made for a specific roofing purpose. The higher the roof, the more specific has to be your sealant choice. Flat and pitched roofs often require different types of sealing and protection.
Flat Roofs
Flat roofs may collect water, since the roofing has little or no slope to direct rain downwards. Due to this, they are prone to leaks and water damage. Flat Roofs – A low-slope or flat roof will require a sealant that is very watertight and flexible, so this includes liquid rubber systems as well as elastomeric (elastic/vinyl/latex) sealants. Due to the cross-linking, these products are extremely resistant towards being walked /driven on and water/rot-resistant. These membranes can withstand severe changes in temperature with no issues. It is important to inspect it regularly and if you see bubbling, cracks or worn spots make sure to reseal those areas.

Pitched Roofs
Because pitched roofs are meant to shed water more easily, leaks often occur where two materials meet (joints), or at flashing details and roof penetrations like chimneys or vents. In these locations, a thick kind of sealer that is weatherproof – usually made from silicone or polyurethane works best. You may not need a whole surface treatment and for sure it should be used at seams and vulnerable spots. Pitched roofs are less susceptible to needing frequent resealing simply because gravity tends to keep water in motion on an angled roof. However, gaps or deteriorating seals should be checked periodically.
Key Takeaway
With flat roofs, it is all or nothing: everything must be covered with waterproofing sealant, whereas on pitched roof you can have weak spot seals which are amplified by the elements between and inside them. For best results, only use one that is rated for your roof type and weather.
