Roof Problems

Something is wrong with your roof and you need to know what it is. What each symptom usually means, how urgent it is, and whether it needs a professional.

Most roof trouble announces itself long before it becomes expensive: a stain on a ceiling, a shingle in the garden, a roofline that has stopped being straight. The difficulty is knowing which of those means call someone this week, and which means keep an eye on it.

These articles work symptom by symptom. Each explains what usually causes it, how quickly it tends to get worse, and where the line sits between something you can assess from the ground and something that needs a person on the roof. Where a symptom can point to more than one cause, we say so rather than guessing on your behalf.
