"Awesome Contractor — Fair Pricing & Quality Workmanship Geno's Siding & Roofing Company replaced my gable vent today. It was the first time that I used this company, and I will absolutely use them again. I am retired, so I watched the entire project and was amazed at how skilled and meticulous the worker (actually the owner) was. The next time I encounter something that I can’t personally fix, I am calling Geno's Siding & Roofing Company at 215-971-6292. Howard (Howie) Walters Langhorne, PA"

Roofing FAQs, answered by experts

The most common slope range for roofs on houses in snowy areas is between 4/12 and 6/12, or 50%. A roof with a slope of less than 10%, or roughly a 2/12 pitch, won’t be effective at shedding snow. However, roofs that are too steep can allow large amounts of snow to build up and fall all at once, creating a hazard for those on the ground.

Before hiring a roofing contractor, it's wise to ask several key questions. Inquire if they are licensed for roof replacement and repair and if they hold any special certifications. Ask if they will be completing all the work themselves or subcontracting parts of it. It's also important to understand the project timeline, whether they will remove the old roof or place new shingles on top, and how they will handle cleanup after the project is complete. Finally, ask about warranties for both work and materials, what recourse you have if issues like leaks arise, and if they can provide customer references.

After you take steps to determine when your roof was last replaced, you may realize you need a new one. Hiring a roofing contractor you can trust involves asking for references and examples of past work. Verify any qualifications the roofer provides. Ask about the expected time to complete the work and about putting guarantees in writing.

This will depend on your existing roof to some degree, but it’s common to raise a roof 4 to 8 feet. The exact amount you can raise is subject to the existing structure. For most homes with average roof slopes—20 to 45 degrees—you can raise the roof around 5 feet.

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.
