"While we hired AllAmerican construction to deal with a gutter issue, which they accomplished by adding a downspout and sealing an end cap, the reason we are giving them 5 stars is that they did a free inspection of of the roof and all things protruding from it. They took pictures of problems they found including openings around 2 standpipes and flashing problems around the chimney. Two days after that first meeting they returned with all the parts and equipment necessary to do the gutter work, replace the standpipes where they exit the roof, and do the flashing replacement/repairs. They also took further pictures of the chimney showing us areas where water has gotten into the chimney structure. We are currently in talks with them about taking the chimney down to the roof line and rebuilding it to fix these problems. We have been very pleased with all three people we’ve been working with-Erica, Jonnathan, and Edison."

"Electrical and plumbing were subcontracted and I have no complaint on their work. However for the work this contractor performed.....It started out okay, complimented his work... But by the time the last of the porch repair and the bathroom reno was completed I realised I had made a huge error of judgement. He insisted in starting the porch work in the fall and then over the winter. When the ground thawed in the spring and the supports no longer met the concrete footing blocks, he used rigid foam boards to shim the concrete blocks up to meet the posts. The floorboards had been removed and proper footings could have been sunk below the frost line, instead it had to be jury rigged and as the ground heave sin the winter and thaws back down, I expect it to be only a matter of time before the folly of this becomes apparent and I will have to get a competent contractor in to fix it. The bathroom was to have a radiant heat floor put in, but the system installed is not meant to be used in a wet room. There is baseboard heat with a pipe running through the floor and that was "sealed" with a piece of moulding and if there is any problem with the heater or the pipe breaks it is harder to get to, nevermind just being able to clean it. I was concerned over the floor system and he promised me that a letter would be coming from the manufacturer saying the system was safe as installed. I spoke to a company rep and they cannot sign off on an installation that they did not witness. So I am unable to recommend this contractor based on any sense I have of his integrity. I am back to using a space heater and When I am able to I will have to have the floor taken up and the correct system put in. There are numerous other minor things, such as the laminate floor being laid with no regard to the pattern on the boards so the same pattern piece was used 3 times next to each other. I did look up how to install this type of floor and found plenty of instructive videos saying how the boards are usually separated by pattern and then laid down in such a way to be random and give the illusion of real wood. The result on my floor does not demonstrate to me an attention to detail. The light over the shower, an upgraded ceiling fan, an additional outlet or two were all part of the plan but were never installed. There were assertions like a new outlet would have cost $400. I checked with the electrician myself and was told that was not the price they would charge and did not understand why that would have been quoted. When issues were raised it was mentioned that he had a lien on someone's house who didn't want to pay for their finished projects. So, there is a lot of work to redo and since the money isn't there I will have to live with things as they are for a while. Not the result I was expecting after 6 months (way beyond the estimated time) of work having been done and at no small expense. I will try to post photos to illustrate what I have mentioned above."

FAQs for natural slate roofing repair projects in Windsor, ME

If more than 30% of your slate roof is damaged, it's time to consider a full replacement. This will prevent further deterioration and avoid costly recurring repairs. A professional slate inspection (costing between $130 and $360) can confirm whether repairs are sufficient or if a full roof replacement is the better option.

A slate roof can last anywhere from 60 to 150 years, depending on factors like installation quality, regular maintenance and repairs, and local weather conditions. Compared to materials like clay and concrete, which often last around 50 years, a well-maintained slate roof offers superior longevity, durability, and long-lasting aesthetic appeal.

Yes, you can use temporary patch solutions, such as roofing cement or patchwork, to provide immediate relief for minor leaks or underlayment issues observed from inside your home. However, these provisional fixes do not replace the need for a permanent, professional exterior repair, which is necessary to ensure the long-term integrity and weather resistance of your slate roof.
