Homeowners Love This Stockton Roofing Company!
It is amazing to me how many "roofers" do not know basic installation rules even on the easiest roofing jobs.
Even more amazing is that people hire them.
Manufactures specifications and building codes are there for a reason and these are MINIMUM requirements.
A good roofing contractor will surpass these rather than undercut them.
For example with shingle and tile roofing the MINIMUM required slope is 2.5/12. At Ron Williams Certified Roof we are certified roofing installers we will not install shingles on less than 3.5/12 or tile 4/12 because if we do, there is a good probability that the homeowner will have leaking issues later.

Tile Roof Important Facts to Know!
Here, roof the slope is 1.3/12 and according to codes and specifications essentially a
"flat" roof and that is why there should not be a roof installation with materials that require a "steep" slope or 2.5/12 and above.
A certified roofer would know this.
Why This Is a Problem
Tile Roofing is considered "water-shedding" rather than "waterproof." They depend on a steep enough slope for water to run off the surface quickly.
When installed on a low slope such as this one in the picture, even the smallest amount of debris accumulation (which will happen even faster with the low roof slope) will cause roof leaks.
In addition, any roofing material warranties will not apply.
