"Ordered and paid for custom awning that was to take 5 weeks. Its now been 16 weeks and still waiting. Owner is at best noncommunicable and at worst, rude. I'm now wondering if this is a scam and not a real business."

Chimney Caps questions, answered by experts

The level of underlayment’s water resistance will depend on the type of underlayment. The most popular underlayment, felt, is water-resistant, but it can’t withstand long direct exposure to rain or the elements. 

Synthetic underlayment is more waterproof, but asphalt is the only fully waterproof type of underlayment.

Common problems include loose or missing shingles, leaks, and weather damage. Regular inspections help prevent major repairs.

While there are many benefits to installing a metal roof on your home, there are some downsides, too. Zinc roofs, in particular, are susceptible to corrosion from overly salty air directly near coastal areas. Another potential downside of zinc roofing is that it must be allowed to expand and contract with the weather. This means special attention is necessary to how it's fastened to the home to avoid issues. 

It’s possible to install your chimney cap in some areas, but it’s usually better to hire a professional. Before you attempt a DIY chimney cap installation, check to see if your local building department requires a permit. If it does, you should hire a professional to pull the permit and complete the work for you. Even if you don’t need a permit, getting up on your roof is dangerous, especially if you have an aggressive pitch or slippery roof material, like metal. Hiring a chimney professional guarantees the job is done correctly and keeps you safe from injury.

The terms “roof sealant” and “roof coating” are used interchangeably to describe the rubber, silicone, polyurethane, or acrylic product applied to the roof’s surface for waterproofing and UV protection. Products like roof caulk can also be called “roof sealant,” but the term is more commonly used for the protective coating.
