"We had them come out to quote installation of windows and ended up purchasing new doors as well. Then we had them quote new siding. They did an awesome job installing the windows we had and removing/re-installing the new entrance and screen doors. Then we had them remove existing siding, install new siding which turned out fantastic. We wanted a couple of things changed and Jose was quick to fix any issues we had or changes we made. We liked DLR enough that we are having them add to our existing deck and do some custom deck building. Jose and his crew show up when promised and will make sure you are completely satisfied with the job before moving on. Absolutely recommend DLR for most any project."

"I am thrilled with my Bathroom- they showed up when they said they would. They listened to my requests - went into the project knowing what the end goal would be. The bill was what they quoted. They cleaned up after themselves. Great customer service and outstanding workmanship."

"Des Moines Area Roofing was professional, trustworthy, and demonstrated excellent attention to detail from initial contact to job completion. Cleanup was so thorough that the next day you wouldn't even know that such a major project had taken place. It has been 2 weeks since the new roofs and we haven't seen even one stray nail left behind (and they did a complete tear down to both buildings, right down to the wood). An excellent company with which to do business. I offer my highest possible recommendation."

"It is a waste of money. The great majority of people are not going to find any value out of the service. If you need design consultation, you need a full service consultation. If you already have knowledge and experience, and you just need to get a few ideas, then you don't need to pay for that. You can just get a magazine or a book since you already have the knowledge of basic designs in your head or a little bit of experience. To have someone call you and give you information over the phone, you are not getting the personal service that you need. You may as well take the money $49 and apply it to something else like getting someone else to come out and give you the service that you need. Because, you are not getting much, you are not getting anything at all. They are going to have you do the work. After talking to them and I was talking to other home designers, I found out that that was a waste of time and waste of money. I gave them a C because they didn't fail at what they do but they don't offer any value for what they do. There's not much value to it. The cost was fair. They didn't do a terrible job and the cost isn't terrible, it was only $49. It just has a very low value. For responsiveness I gave them a B because they will answer your phone and answer your emails."

"Once I sent her all the measurements, it took her a little while to get the options back to me.  Overall, they're good designs.  However, they're very simplistic and give general ideas for space planning.  I was hoping to have a better idea for sizes of furniture for the space and some variations on staging.  
Jill was very responsive when I did have a question.  I'm not sure how helpful it is to have a virtual design done.  If we lived in similar cities, I'd probably use her again for help with additional designs.

FAQs for addition to existing structure building service projects in Pilot-mound, IA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
