You can put new shingles over old shingles, but most municipalities only allow for two layers of shingles before you have to rip off the old roof and start fresh. In some areas, only a single layer of shingles is allowed due to the weight a bundle of shingles adds to your structure. In most cases, it’s a good idea to remove your old shingles before you install new shingles, especially if you suspect that a roof leak may have compromised the decking underneath.

The cost to install roof heating cables typically ranges from $500 to $2,000, with an average of around $1,000. On a per-foot basis, you can expect to pay between $8 and $15 per linear foot. Key factors that influence the final price include the size and complexity of your roof, roof pitch, the type and length of the cable, the price of the system itself, labor fees, and whether any additional electrical work is required. Generally, smaller roofs will cost less than larger ones. The total cost usually includes both materials and professional installation.

Just like when you’re shingling a roof, you can install felt underlayment under a metal roof, but a synthetic underlayment like adhered ice and water shield is the best option. These use adhesives rather than mechanical fasteners, so you have fewer penetrations going through your roof deck and a lower risk of leaks. Ice and water shield is also easier to install because you don’t need additional tools or fasteners to attach it to the roof deck.

Copper roofing works well in all kinds of climates, but it’s ideal in humid climates because it naturally repels fungus, moss, and algae. This makes it one of the best roofing options for Cape Cod homes in the Northeast, as well as homes in the humid southern states and snowy northern states. That said, copper is vulnerable to thermal expansion. If you live in a climate that has extreme temperature changes, your contractor will need to consider this during the installation process.
