Customers say: Quick response

"I called and left a message for a call back on Sunday and Jessie called me back on that Monday. I found him to be pleasant and very easy to work with. I advised Jessie what the problem was with mine and my tenants roof and I ask him what he thought it would take to repair both sides. He had quoted me a price, but after his assistant had looked at what was needed, he was upfront and advised that it would be more and gave me a bottom line price which I thought was reasonable and fair. Jessie's assistant came and completed the project in one day and I was pleased with the finished product. Thanks Jessie, I will refer and use your services again in the future."

"The decision to replace a roof is a big one, and Peak Roofing helped guide us every step of the way in the process. We had an old failing metal roof on our rental property. Damian, one of the partners, walked us through every step of the process and was very patient with all of the questions that my grandfather and I posed. He was very quick to fit us into the schedule. He was incredibly knowledgeable and informative regarding a type of roofing membrane that would fit well onto our style roof (lean-to flat roof). Tony, the other partner of the company accommodated the drop off location of the down payment, and even met us at our home so that my grandfather did not have to drive at night. On the day that the work commenced (and was completed!), Carlos, the foreman, kept me informed throughout the day of all progress. The team they brought along were so quick, efficient, and safe. They protected all utilities during construction and cleaned up before leaving. They will be coming back to install gutters on the home as well, soon as a few other projects get done. I am happy that they are able and willing to phase the work into different days. I would recommend Peak Roofing to anyone! They are professional and attentive. We are very happy with the product and especially the customer service."

"I gave Tj my vision of a new open concept porch and new metal vertical siding and he and his team brought it to reality. It was far nicer than I even expected. The whole crew are very polite, professional, reasonable and very detail oriented. This is 2nd major project they did for us. Last year they did garage expansion and metal roof and siding. I love my house now all because of Tj. Will be using them again infact just asked for an estimate on new bathroom floor."

Roofing FAQs, answered by experts

The best kind of tarp for a roof is one that will stand up to the elements, weather, and sun. Viny roof tarps are known for their durability and resistance to water, tears, and mold—making these tarps a good choice for use in winter conditions and the summer sun. Polyethylene tarps are also quite durable and waterproof.

If you need to replace the roof over your attached garage, a roofing contractor can perform what is called a partial roof replacement that only affects garage roofing. However, it's important to keep in mind that only replacing a portion of your roof creates a situation where your roofing has two different lifespans. You will also miss out on the opportunity for a full roof warranty. In some cases, having two different roofs on your home could increase risks for leaks. When replacing the roof on a detached garage, homeowners have the option to make the project bigger by upgrading their home roof alongside their garage roof. However, this isn't necessary if your home has a newer, properly functioning roof. It is better to try to match the new garage roof to your home's existing roof instead.

Most Cape Cod houses are two stories tall at the peak, although they’re considered one-and-a-half stories tall because the steep roof pitch cuts off a portion of the living space on the second story. Unless you raise the roof on your Cape Cod house to add a dormer, the interior rooms upstairs will lose some usable living space to the sloped ceilings.

Underlayment is required by building code, so any roof installed without it is technically against code. The underlayment acts as the second layer of defense against water, so installing a roof without underlayment means a much higher risk of roof leaks. You’ll have the best chance of avoiding roof leaks if you install drip edge flashing covered by underlayment, and then install your roofing material over that.

You can technically install a metal roof over asphalt shingles, but it isn’t a good idea. This is because you’re essentially creating a moisture barrier under the metal, which can easily—and often does—lead to significant mold damage. Removing an asphalt roof isn’t terribly expensive, and some roofing companies might cut you a serious labor and disposal discount if you add it to a new install.
