Hello my names Christopher i am 23 tired of working for a boss that doesnt understand what goes into things when we install. I have finally turned over a new leaf and wanted to start dping things on my own. I have worked for a few different landscaping companys, i have done some demo work for family and friends, i also worked at thrasher for ahile working my way up to team lead. I just had a baby last year on December and i want to be able to see her grow! Thats why im here to get jobs that i want. I dont wanna work for a boss who has no idea how the stuff i install goes in. I want to be thats hands on boss that is for the customer. Tired of meeting quotas. I want to love what i do for work and believe you me i love getting dirty and getting the job done.

Roofing questions, answered by experts

Roofing estimates vary for many reasons, but the most significant ones include differences in the cost of labor based on the contractor’s experience and overhead costs, as well as the quality of the materials your roofer will use for the job. You should get your estimates itemized and make sure your contractors include details about the materials they plan on using. Doing so allows you to compare not only based on the cost but also the value that you’ll get for your money.

Look for certified local roofing contractors with plenty of experience working with cedar. There are also several important roofing questions to ask before choosing a roofer, including whether they are licensed, bonded, and insured. Once you’ve rounded up a few good candidates, compare estimates and hire whoever gives you the best bang for your buck.

In most cases and locations, roofs with a single layer of asphalt roofing shingles won't require roof removal before installing a metal roof. However, underlayment may be necessary on roofs with moderate shingle damage. Heavily damaged roofs or ones with multiple shingle layers will most likely require removal before a metal roof can go on.

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.

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.
