"This roofing job started off bad and continued to the finish. I wanted a professional with a few requirements. Be careful of original structure as it is prefabbed. The workers punched twelve holes in sheeting removing old roof material, requiring sheeting overlay. I requested that roofing nails not protrude through roof in patio area. They were protruding through the entire area. They left refuge sitting on the side of the driveway until I asked to have it removed. The one-week job turned into a two-month Odessey. The job was obviously a side job, piece-mealed together with little supervision little supervision. I am not confident the roof will not fail. prematurely fail. "

Modern Method Roofing maintains superior standards, encourages truth, honesty and fairness in the marketplace, and responsive customer service.

"I had two jobs done by modern method on my rental property. one in 2016 and one in 2019. One was a skylight leak repair and the other a section of leaking flat roof. both jobs took a couple months to mobilize in winter. The skylight repair failed after 3 years. The other section was done with white material, while the rest of my roof is brown, so it looks pretty terrible. As the owner, I was never made aware of this decision- they worked directly with my property manager which I consider unprofessional considering they changed my roof color. I called them out to see what can be done about both. They told me the skylight repair was not done the right way and needed to replace the entire roof section including the skylights. They also said they would torch down some brown material over the white material they provided and quoted me for both. I tried to appeal to them as to why I would give them even more money to do my skylights when they recommended the repair that failed, and also why in the world they would change my roof color. The estimator gave me some options including torching brown material down over the white, paying full price for all of the repair. I called to complain, and they sent their owner over who basically told me that any flat roofing is always done with white material (sorry, not true), that torching brown material over the top is not a very good thing to do, and that the skylights obviously need to be replaced. He didn't have anything to say about why I should trust them to do good work other than "I wasn't involved in the conversations, so I don't know". Very disappointed."

Roofing questions, answered by experts

Winter is the least expensive time of year to replace a roof due to decreased demand. However, it’s not an ideal time to replace your roof, as there are numerous factors that can inhibit the work, including shorter days, snow and ice, and cold temperatures.

Hail is unlikely to damage a tar and gravel roof because the hailstones will hit the protective gravel rather than your delicate roof membrane. A tar and gravel roof is the most resilient flat roof option, which means it’s the best one for areas that see hail, fallen tree debris, and blown debris from intense winds.

Walking on an asbestos roof can pose a risk. Asbestos roofing materials can become brittle over time, increasing the chances of them breaking or releasing fibers when stepped on. Additionally, walking on an asbestos roof without proper precautions can cause further damage to the material. If possible, avoid touching an asbestos roof in any way and consult with a professional about removing and replacing the roof. 

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.

A tarp can temporarily stop a roof leak, but how long the solution works heavily depends on the placement and size of the leak. While a tarp can be a temporary solution, it’s crucial to have a professional inspect and repair the leak as soon as possible to implement a permanent fix.
