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.

Roofing questions, answered by experts

Maybe you waited a little longer than you should have before dealing with the snow accumulation on your roof, and now you are wondering if there is risk of roof collapse. Here are some signs you should look out for: a sagging roof, cracking and cracking sounds, cracks in walls, and leaks in your attic and ceiling.

If you suspect potential roof collapse, do not delay. Take immediate action. Call a professional roofing company and get an inspection. You may want to move your belongings to a safe place and relocate your family until everything has been taken care of.

You can install a spray foam roof over shingles, but it may compromise the roof’s protective qualities or shorten its lifespan. Before installing a new roof, ask a qualified roofer if your existing roof needs to be removed before installing a spray foam roof so you ensure your home has quality, long-lasting protection. 

Removing snow from your roof can help prevent ice dams, but the best thing to do is address insulation issues in your attic. If you do decide to remove the snow manually, you should always use a roof rake rather than a shovel. You shouldn’t climb your snowy roof in any circumstance, and roof rake allows you to remove the snow from the ground or a ladder. For the best results, remove snow as soon as possible after it falls.

Sometimes chimney caps blow off during storms or fall off after rusting away. While this typically won’t cause structural damage, failing to replace a chimney cap can. A chimney cap prevents moisture, animals, and debris from entering your chimney, all of which can cause serious problems, such as damage to the masonry or blockages in the flue.

The level of underlayment’s water resistance will depend on the type of underlayment. The most popular underlayment, felt, is water-resistant, but it can’t withstand long direct exposure to rain or the elements. 

Synthetic underlayment is more waterproof, but asphalt is the only fully waterproof type of underlayment.
