"Roca roofing just replaced my roof and did a VERY good job. Jerry Roca helped me
with the Insurance claim and that was wonderful, he made sure that I got all that I was entitled too. He did a great job on
my roof. I can't recommend him enough. I would refer anyone to Roca roofing. They're good people.

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

Mold Testing and Remediation FAQs, answered by experts

Mold doesn’t require much airflow to make it out from behind walls and into your living space, making you sick. HVAC systems can actually pull the mold from behind walls and spread it through your home. While the mold may be out of sight, moisture transfer from the wall can also spread the mold from behind the wall into your living space and air. Any cracks in the walls or bad insulation only compound this effect. 

Professionals suggest through ventilation, source removal, or filtration systems.

Toxic black mold on wood appears as dark green or black patches. It often has a slimy or wet texture and may spread across the surface in a spotty pattern. The affected wood might appear discolored, soft, and damp. Identifying black mold early is crucial because it can cause severe health problems when its spores are released into the air. Prompt remediation is necessary to prevent further damage and health risks.

No, not all black mold is toxic. Although people often refer to stachybotrys chartarum as toxic black mold, there is little evidence that any one type of black mold has more toxicity than another. People who have an allergy to black mold would be more likely to have a dangerous reaction after inhaling it. Long-term exposure to black mold spores can lead to severe infection and disease. Some people only have minor health problems after black mold exposure. Ultimately, toxicity is rare with any kind of mold, but it is possible, so always take the appropriate precautions.

Efflorescence itself won’t turn into mold, but it can cause moisture problems, which can lead to mold. It’s important to address an efflorescence problem as soon as possible, as mold can pose health risks and even compromise the structure of your home.
