Low SLope Roofing

Roofing with a slope of 10 degrees or less is said to have a modest slope. They are frequently utilized for business and manufacturing facilities, as well as in certain residential construction. Despite the common misnomer, roofs with a low slope are not truly flat.

Advantages of Low-slope roofs 

  • Roofs with a shallow pitch don’t cost as much to put up.
  • They are also simple to fix if something goes wrong.
  • Low-slope roofs can be constructed from many different materials, providing design and cost versatility.
  • Green roofs and solar roofs are only two of the many roofscape options available when working with low-slope roofs.

Various Low Slope Roof Designs

  • There are three primary types of low-slope roofing systems:
  • Flat/membrane systems: The roof in these systems is protected by a single membrane.
  • Multiple layers of asphalt, felt, and tar are used in the Built-up Roofing System (BUR).
  • The membrane in a modified bitumen system is more impervious to the effects of sunlight and other environmental conditions.

Low-slope Roofing Materials.

  • These are the most typical materials for low-slope roofs.
  • Tar and asphalt are low-cost and simple to work with.
  • The elements have no effect on metal or sheet metal because of their resilience.
  • Lightweight and simple to set up, single-ply membranes are a great option.

Procedure for Low-Slope Roof Installation

The method of installation for low-slope roofs differs from the chosen system.

But the fundamentals are as follows:

In other words, get the roof ready.


  • Lay the subfloor.
  • Lap the roof membrane in place.
  • Low-slope roofs have a longer lifespan provided they are regularly maintained and inspected.
  • Low-slope roofs need to be checked for damage and wear once a year.

The most typical issues with flat roofs are:

  • Leaks
  • Issues with drainage
  • Inadequate Sealing
  • Water pooling
  • Photochemical deterioration
  • Change for the worse
  • Inflated or blistered areas
  • Fracture

If any of these issues are discovered, they need to be fixed immediately to avoid any additional destruction.

Common Issues with Low-Slope Roofing and How to Fix Them?

The most prevalent issue with roofs that have a shallow pitch is leaks. Many things can set them off, such as:

  • Roof membrane tears or punctures
  • Inadequate set-up
  • Faulty lighting
  • Drains that are clogged or blocked
  • Leaks can be a symptom of, or even the cause of, poor drainage. Potential triggers include:
  • Roof has the wrong pitch
  • Drains that are clogged or blocked
  • Gutter overflow

Water can leak through a roof and cause damage if the seams aren’t properly sealed. Possible causes include:

  • Inadequate set-up
  • Faulty lighting
  • Roof membrane damage

Water pooling on the roof: This might cause the roof membrane to stretch and eventually leak. Possible causes include:

  • The roof has the wrong pitch
  • Drains that are clogged or blocked
  • Gutter overflow
