Community Involvement

“ The service provided by Allied Construction was TOP NOTCH. They were there the day after my shingles blew off in the storm. They helped me through the insurance struggle, and worked with me throughout the whole process. The crew they sent out to do the work was also TOP NOTCH. My wife works from home and was prepared to have to change her schedule because of the noise, but did not have to at all. So she was very satisfied. They got the job done in record time and had everything cleaned up and spotless, like they were never there. I will and have recommended them to everyone I know. ”

“ I recently had roof and sliding damage from hail but had never dealt with an insurance claim like this. The team at Allied handled everything with our insurance and made the process so easy. The quality of work and attention to detail was second to none. I highly recommend these guys for all your roofing, siding and construction needs. Thanks again Allied! ”

Tyler S.

“ Allied Construction just finished helping our senior living facility through a water emergency. The crews were fast to respond. They brought in air scrubbers (commerial dehumidifiers)and fans, they pulled drywall and flooring only where needed. They continued to monitor and communicate with site staff until the project was complete. They were great to work with and great with our residents! ”

Brenda S.

“ Rick came by and marked all of the damage on the roof and siding before the insurance inspector arrived. We ended up having both the roof and siding covered by insurance and Allied took care of all the negotiations with the insurance company. Besides knowing insurance, they have a great crew who were really thorough in all of their work, clean up and inspections. I don't think the experience could have been better. Thank you Allied Construction ”
