Hawaii is no stranger to heavy rainfall. While it might seem advantageous to have a roofing contractor protect your roof with an additional product, applying coatings to shingles can have negative consequences in the long run. Here’s why:

Why Coating Shingle Roofs Is a Bad Idea

Strengths of Shingles

Applying shingles requires the assistance of an experienced roofing contractor. For the roof to be as waterproof and durable and possible, nails need to be placed in precise locations. When done correctly, shingles provide ample protection against water leaks and can withstand strong winds. These strengths, however, can be compromised when additional coatings are applied.

How Coatings Affect Shingle Durability

There are several things that can go wrong when coatings are applied to shingle roofs. The most basic issue, however, is that shingles are simply not designed to be coated. Some types of coatings, such as hydrocarbon solvent-based varieties, can actually alter the durability of the shingles by softening them. This, of course, can spell disaster if large amounts of water or heavy winds affect your roof.

If the shingles have been placed by a roofing contractor that doesn’t have much experience with proper nail placement, a coating can lead to significant damages. Heavy rainfall can actually get trapped in small crevasses and deteriorate the roofing materials over time. Applying an extra product can also affect drainage by reducing flexibility and natural movement, causing water to pool and leak in.

Temporary Benefits, Long-Term Trouble

If there are any positive effects of having a roofing contractor apply a coating to shingles, they are only temporary. At some point, the heavy rainfall of Hawaii will get the best of the roof and cause problems that could’ve been avoided by concentrating on other roofing repairs and replacements.
