"This company is outstanding. They tore off the old roof and replaced a new roof in 9 hours with a crew of 7. Everything was put back in place and cleaned up perfectly. I did not find one nail anywhere after they left. This is the second time High Top Roofing was contracted to do the job in 18 years. Great company and Dan is wonderful to work with."

"I am very happy with the new roof. Daryl, the sales rep, communicated everything very nicely and made sure that I was given the best option for my roof. Mike, Devan, and Walter were the project managers and they were very helpful throughout the roof install. I wasnâ t able to communicate very well with the roofing crew but the project managers made sure that all of my concerns were taken care of."

Roofing questions, answered by experts

The golden ratio for roof pitch is 1:1.62. It’s simply a standard aspect ratio that home and building designers and architects use when deciding how steep a roof should be to maintain visual appeal. The golden ratio can apply to any home or structure with a visible roof that isn't considered a flat roof.

The most common defect in a flat roof is leaking. Flat roofs have minimal slope, so water pools more readily on a flat roof than on a sloped roof, and the risk of the waterproof membrane failing increases with exposure. Tears and punctures from foot traffic and blown debris are other common problems, especially with single-ply roofing membranes like TPO and EPDM roofs.

Gaps between tiles are necessary to help with weatherproofing, allow for thermal expansion, and increase wind resistance. In general, a small gap no larger than 3 millimeters wide will encourage proper drainage and limit cracking. Beyond that, tiles should overlap a minimum of 3 inches, except at the eaves where they should extend to the center of the gutter.

In most cases, below 40 degrees Fahrenheit is too cold to replace a roof. The cold affects the shingles, making it more difficult to adhere them to your roof. It also becomes dangerous for contractors to get up on your roof in the cold weather, as there can be ice and slush causing surfaces to become slippery.

In general, you should consider replacing your roof if more than 30% of it is damaged. This includes several missing shingles, large spots of granule loss, extreme curling or cracking, structural damage to the roof's decking, or multiple areas of leaks. All of these issues could indicate compromised structural integrity that requires roof replacement.
