Reroofing over old shingles is generally not recommended due to several concerns. Adding a new layer increases the weight on the roof structure, which can be problematic, especially for older homes. It can also conceal underlying issues such as rot or leaks, which may worsen over time if not addressed. The new shingles may have a reduced lifespan because the underlying layer can trap heat, leading to faster deterioration. Additionally, the surface may not be as smooth, affecting the overall appearance of the roof. Some shingle manufacturers may void warranties if their products are installed over existing shingles, and local building codes may restrict the number of shingle layers allowed. For these reasons, it's often better to remove the old shingles before installing new ones to ensure a long-lasting and effective roofing solution. Consulting with a professional roofer can provide guidance tailored to your specific situation.

To fix a sagging roof, it's important to first inspect the area to identify the cause, which may include structural issues, water damage, or excessive weight from snow or debris. If accumulated snow or debris is contributing to the sag, carefully remove it to relieve pressure. Reinforcing support structures, such as adding new rafters or braces, may be necessary to provide additional strength. Given the complexity and potential safety risks, consulting a professional roofing contractor or structural engineer is often the best course of action to ensure a proper and safe repair.

If some shingles have fallen off your roof, there's a possibility that it could lead to leaks, especially if the underlying layers are exposed to the elements. Shingles are designed to protect your roof from water infiltration, so missing shingles can compromise this protection. It's important to address the issue promptly to prevent potential water damage. Inspect the area for any signs of leaks or damage, and consider contacting a professional roofer to assess and repair the affected area to ensure your roof remains watertight.

Yes, you can fix part of a roof, especially if the damage is localized. Common scenarios for partial repairs include replacing a few missing or damaged shingles, fixing leaks in specific areas, or addressing issues with flashing around chimneys or vents. However, it's important to assess the overall condition of the roof; if the roof is old or has widespread damage, a partial repair may only be a temporary solution. Consulting with a professional roofing contractor can help determine the best course of action based on the specific situation.

As a rule of thumb, a standing seam metal roof costs roughly 2-3 times the average asphalt shingle roof.

Deciding whether to repair or replace a roof depends on factors like the extent of damage, age of the roof, cost considerations, and long-term benefits. If the damage is minor and the roof is relatively new, repairs may suffice. However, extensive damage, an aging roof nearing the end of its lifespan, or the desire for improved energy efficiency and home value may warrant a full replacement. It's also important to consider any existing warranties on the current roof, as they may cover some or all of the replacement costs. Consulting with a professional roofer for an assessment and weighing the costs and benefits can help you make the best decision for your specific situation.
