August 28, 2016 | Filed under: News
Investigating a warped and wavy roof can be difficult. A wavy roof is an unsightly thing. It immediately detracts from the appeal and look of a home. While a wavy roof is aesthetically unpleasing, does it affect the performance of the roof? To determine if a wavy roof is more than just an eye sore, you must determine the reason for the wave. We will highlight the 4 main causes of a wavy or warped roof. As always, contact a professional for a thorough inspection and roofing consultation. Be careful if you are inspecting the roof yourself as a warped roof is potentially dangerous to walk on.
Installation
Poor installation can result in a wavy roof. It is important to use a reputable, trusted contractor for your roof. Remember, you get what you pay for. If you’re only after the lowest quote, expect the lowest results.
Product
Some products are more prone to waving than others. Asphalt shingles are the most likely to be wavy Asphalt will curl and warp significantly more than better quality, sustainable products. Asphalt shingles are low quality material and have a low quality look. Metal roofing options not only help diminish the appearance of imperfections, they also prevent some of the leading causes of wood warp.
Foundation
Even though your roof is on the top of your home, there is a foundation to it. The foundation of your roof in comprised of the framing and includes the decking. The decking is the plywood that covers your entire roof and is the foundation for your shingles. Any problem with the decking can result in a visible wave on the roof. Damaged decking can be potentially dangerous. It could be an indication of water leaking through the shingles or a problem with your ventilation. If you think this might be the case with your roof, consult a professional for an inspection. Our crew members always address any potential decking issues and exercise caution over speed.
Underlayment
Underlayment is what we call the product placed between the decking and and the shingles. When referring to asphalt shingles, felt paper is what is typically used in this application. Having wet or poorly placed felt paper under your shingles can cause your roof to be wavy. This type of roof wave is usually only seen after a new installation of wet or bunched up felt paper under asphalt shingles. We use high grade synthetic underlayments that do not hold moisture. Our installers also take great care in making sure the underlayments are applied perfectly.
