Why Does My Roof Look Wavy?

Category: Roof Repairs • June 24, 2021

A residential roof serves multiple purposes. But there’s little argument over which two head the list:

  • Create a protective seal between home and the elements.
  • Improve your home’s aesthetic appeal.

But that doesn’t mean all roofs are installed correctly or achieve the added touch of elegance and refinement you had in mind. A new roof can appear bumpy, wavy, or lumpy, for example. And given the fact you’re bound to look at it daily, that kind of roofing mistake can be hard to swallow.

Where causes an ill-looking roof? Let’s have a look.

Common Causes of a Wavy Roof

If your shingles are not lying flat as they should be, it could be due to the roof’s age, condition, the weather, or installation.

  • Multiple Layers – In some instances, it’s perfectly acceptable to place more than one layer of shingles on a home. Doing so can save homeowners the cost of tearing off the existing shingles and hauling away the debris. However, if the old roof had bumps, lumps, or waves, the new layer would likely take on that same form.
  • Shingle Seal – Asphalt shingles typically have an adhesive strip that, when heated by the sun, bond the shingles together so they lay flat and in place. If weather conditions aren’t right or if wind catches the shingles before they seal, a new roof can look wavy in some areas. In most cases, this can be remedied by applying a temporary adhesive.
  • Defective Roof Shingles – Lower quality shingles can sometimes be easily torn and may not adhere to each other properly, resulting in lumps and waves. For better results, purchase high-quality materials from a trusted roofer or manufacturer, those who stand behind their materials and installation.
  • Poor Installation – If the problem persists after the shingles have had sufficient time to bond, and no waves were present on original shingles or you’ve only had one layer installed, the issue could stem from poor installation. When choosing a roofing contractor, always do your research, ask for references, and check online reviews.
