Get matched with top roofers in Rochester, MI

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.

It’s possible for a roofing estimate to change after the initial assessment, but in most cases, it shouldn’t. There’s always the risk that something unexpected will happen that causes prices to go up, like discontinued materials or your roofer discovering previously hidden damage to your decking when ripping off the old roof. However, experienced roofers should account for these circumstances in their initial estimates. Roofing contracts are binding, so always check your contract for language about how and why your numbers could change.

You can install a spray foam roof over shingles, but it may compromise the roof’s protective qualities or shorten its lifespan. Before installing a new roof, ask a qualified roofer if your existing roof needs to be removed before installing a spray foam roof so you ensure your home has quality, long-lasting protection. 

A chimney cap costs about $300 on average to install, with prices ranging from $75 to $1,000. The final cost depends on several factors, including the professional you hire, the accessibility of your chimney, the cap's material and size, whether any repairs are needed, and if it requires custom fabrication. Chimney caps are usually made from galvanized steel, stainless steel, or copper. Copper caps are the most expensive, followed by stainless steel and then galvanized steel. Excluding labor, average material costs are around $100 for galvanized steel, $250 for stainless steel, and $600 for copper. You may also face additional costs, such as hiring a chimney sweep to clean the chimney before the cap is installed.
