"Excellent. Gary’s pricing was fair and reasonable, despite the difficult market right now in acquiring any construction supplies, and roofing supplies in particular. He kept us apprised of anticipated start date and started work in a timely fashion. He and his crew were careful and thorough, rather than rushing to get done, and the work quality was excellent. Any and all needed additional work- not unanticipated with a 30 year old roof, was explained and approved ahead of time. Post work site clean up was pristine. I enthusiastically recommend Gary and High Tech Roofing."

"I recently had my roof replaced by Local Construction, and I could not be happier with the results. From the initial consultation to the final cleanup, the entire process was smooth and professional. The team was efficient, skilled, and completed the job in a timely manner. The new roof not only looks fantastic but has also significantly improved the insulation. I highly recommend this roofing company for anyone in need of a reliable and top-quality roof replacement service."

"I contacted Klestian from All Point Roofing company regarding the hail and wind damage on my roof. He went thru a thorough inspection on the roof and submitted the report with the pictures of the damages. Followed by explanation about the new roof installation process in details. The whole roof installation went well and on time. No mess left on the ground. Besides the good quality work he and his team did, I found that him being responsive and attentive to accommodate customer needs is one of the key factor that make me seal the business with All Point Roofing company!"

Roofing FAQs, answered by experts

Flapping shingles, or shingles that are lifting or curling away from your roof, can be glued back into place using roofing cement or sealant. Apply the glue underneath the shingle, then press it down firmly. You can leave a brick on top of the shingle to hold it in place overnight while the sealant dries.

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.

Roll roofs don’t last as long as traditional roofs, like those made of asphalt shingles. A roll roof typically lasts between five and 15 years, whereas a shingled roof will last between 20 and 50  years. Modified bitumen roofs are similar in look to rolled roofing but have a 12 to 15 year warranty.

Roofing replacements and repairs expose the interior of your home to the elements. Failing to protect these areas during inclement weather can cause extensive damage and job delays. Have a conversation with your pro to learn their plans to use tarps, plastic sheeting, or other waterproofing methods to keep your home safe. Also, ask whether your pro will inspect your home during rain or snow to ensure the covering works.

It’s possible for a roofing estimate to change after the initial assessment, but in most cases, it shouldn’t. There’s always the risk that something unexpected will happen that causes prices to go up, like discontinued materials or your roofer discovering previously hidden damage to your decking when ripping off the old roof. However, experienced roofers should account for these circumstances in their initial estimates. Roofing contracts are binding, so always check your contract for language about how and why your numbers could change.
