ROOF-OVERS ARE NOT A GOOD CHOICE
Roof-overs, also known as roof coverings or roof coatings, involve installing a new layer of roofing material over an existing roof rather than removing the old roof. While roof-overs may seem like an attractive option due to their potential cost savings and the convenience of avoiding a full roof replacement, there are several reasons why they are generally not considered a good long-term solution for homeowners.
At Sunrise Roofing, we not only do not recommend roof-overs we will not perform this type of roofing technique. Below are our main reasons for not performing this task and the many drawbacks that exist with a roof-over product:
- Conceals underlying issues: By covering up the existing roof, roof-overs can mask underlying problems such as damaged decking, rotting wood, or leaks. Failing to address these issues can lead to more significant problems over time and potentially costly repairs in the future.
- Adds weight and stress: Installing an additional layer of roofing material adds extra weight to the structure. This can place additional stress on the roof’s supports and framing, potentially compromising its structural integrity. If the existing roof is already near its weight limit, a roof-over could lead to further problems and reduced durability.
- Reduced lifespan: Roof-overs generally have a shorter lifespan compared to a complete roof replacement. The new layer of roofing material may deteriorate more quickly due to exposure to UV rays, temperature fluctuations, and other weather conditions. Consequently, homeowners may need to replace the roof-over sooner than if they had opted for a full roof replacement initially.
- Limited warranty coverage: Roof-overs often come with limited warranty coverage, especially if they are installed over an existing roof. This limited warranty might not provide sufficient protection in case of material or installation defects, leaving homeowners responsible for any necessary repairs or replacements. The manufacturers we use at Sunrise Roofing provide, No Warranty
- Aesthetics and property value: Roof-overs can affect the overall appearance of a house. Adding an extra layer can create a bulky or uneven look, especially if the underlying roof has irregularities. This can potentially impact the curb appeal and property value of the home, which may be important considerations for homeowners.
- Potential code compliance issues: Some jurisdictions have building codes that regulate the number of roofing layers permitted on a structure. Installing a roof-over might exceed these code limits, potentially resulting in compliance issues and difficulties when selling the property.
- Excess heat: Roof actually stays hotter and shingles gradually shrink causing issues with the second layer of shingles and loosening nails.
- Future costs: When a future roof is necessary the expense will increase to take off both layers of roofing materials.
While roof-overs can provide a temporary fix or be suitable under limited circumstances, it’s generally recommended to consult with a professional roofing contractor like Sunrise Roofing who can assess the specific needs of your roof and advise you on the best course of action.
In all cases, a complete roof replacement is a much more reliable and cost-effective solution in the long run, ensuring a structurally sound and durable roof for your home that you can enjoy for years to come.
